Introduction
Constraint-Induced Movement Therapy (CIMT) consists of a set of rehabilitation techniques designed to reduce functional problems in the most affected upper extremity of clients with strokeAlso called a “brain attack” and happens when brain cells die because of inadequate blood flow. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. 80% of cases are also know as a “schemic stroke”, or the formation of a blood clot in a vessel supplying blood to the brain. More. This therapy involves constraining movements of the less-affected arm, usually with a sling or mitt for 90% of waking hours, while intensively inducing the use of the more-affected arm. Concentrated, repetitive training of the more-affected limb is usually performed for six hours a day for a two to three week period. Compliance of the patient for the rigorous restraint and training schedule, as well as the required intensity of therapy provided by therapists in a clinical setting, are important issues to consider.
Modified CIMT (mCIMT) is a less intense treatment that involves the same principles as CIMT (i.e. restraint of the less-affected upper extremity and practice of functional activitiesAs defined by the International Classification of Functioning, Disability and Health, activity is the performance of a task or action by an individual. Activity limitations are difficulties in performance of activities. These are also referred to as function.
of the more-affected extremity), but with less intensity than traditional CIMT (i.e. less time). The common therapeutic factor in all CIMT techniques includes concentrated, repetitive tasks with the more-affected arm.
Functional benefits appear to be largely confined to those individuals with some active wrist and hand movement. Studies have explored the efficacy of this intervention for improving functional outcomes post-stroke.
A number of neuro-imaging and transcranial magnetic stimulation studies have shown that CIMT can produce a massive use-dependent cortical reorganization that increases the area of cortex involved in the innervation of movement of the more-affected limb (Taub et al., 1999). In terms of studies examining the effectiveness of this treatment intervention, high quality randomized controlled trials (RCTs) have reported a positive impact for patients with strokeAlso called a “brain attack” and happens when brain cells die because of inadequate blood flow. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. 80% of cases are also know as a “schemic stroke”, or the formation of a blood clot in a vessel supplying blood to the brain.

What is constraint-induced movement therapy (CIMT)?
After a strokeAlso called a “brain attack” and happens when brain cells die because of inadequate blood flow. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. 80% of cases are also know as a “schemic stroke”, or the formation of a blood clot in a vessel supplying blood to the brain. More, regaining strength and function in your weaker arm (the side weakened by the stroke) can be challenging. Constraint-Induced Movement Therapy (CIMT) involves intensive training of the weaker arm while restricting the use of the stronger arm. Specifically, the use of the stronger arm is restricted by the use of a mitten or a sling for much of each day. The idea is to encourage you to use your weaker hand to do daily activitiesAs defined by the International Classification of Functioning, Disability and Health, activity is the performance of a task or action by an individual. Activity limitations are difficulties in performance of activities. These are also referred to as function.
. This therapy has been studied by high quality research studies and has been found beneficial for arm function in some patients- especially those who already have some use of their arm and hand.
The use of an arm sling during walking training. The sling makes it impossible to use stronger arm. The man must use his weaker arm to hold
Use of a mitten while writing. The mitten makes it impossible to use the good arm. The woman is forced to use her weaker hand to write
Are there different kinds of constraint-induced therapies?
The term “CIMT” is used to describe a newer technique based on older existing techniques that force the patients to use their weaker arm. These older techniques are called “forced-use” therapy. The goal is to intensively train the weaker arm by using it to perform daily tasks such as preparing meals, engage in fun activitiesAs defined by the International Classification of Functioning, Disability and Health, activity is the performance of a task or action by an individual. Activity limitations are difficulties in performance of activities. These are also referred to as function.

such as writing.
More recently, research has looked at the benefit of modified CIMT (mCIMT), which is based on the same principles as CIMT but with less time wearing the restraint and fewer hours of exercise each day.
What is it used for in people with stroke?
The goal of CIMT is to help regain strength and function on the weaker side of the body, typically the side affected by the strokeAlso called a “brain attack” and happens when brain cells die because of inadequate blood flow. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. 80% of cases are also know as a “schemic stroke”, or the formation of a blood clot in a vessel supplying blood to the brain. More. CIMT is used for a variety of purposes. Here we describe its use for arm and hand therapy.
Does it work for stroke?
As already mentioned, this therapy has been examined using high quality research studies and has been found beneficial for arm function in some patients after a strokeAlso called a “brain attack” and happens when brain cells die because of inadequate blood flow. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. 80% of cases are also know as a “schemic stroke”, or the formation of a blood clot in a vessel supplying blood to the brain. More – especially those who already have some use of their arm and hand.
Although researchers are not exactly sure of how it works, some experts suggest that CIMT affects the brain by enlarging the brain area controlling the weaker arm. Research studies have reported that patients who receive CIMT have better control of their weaker arm and better ability to perform daily activitiesAs defined by the International Classification of Functioning, Disability and Health, activity is the performance of a task or action by an individual. Activity limitations are difficulties in performance of activities. These are also referred to as function.

What can I expect?
Your therapist will decide with you what regime is most suitable for you. However, CIMT typically requires you to wear either a large mitten or an arm sling on your stronger arm, many hours a day, seven days a week, for about two weeks or more. The mitten or the sling is worn to encourage you to use your weaker arm and hand to do everyday tasks. In addition, the occupational therapistIn charge of the “assessment of personal and domestic care activities; evaluation and treatment of functional impairments related to change in sensorimotor, cognitive and perceptual abilities; prescription of wheelchairs and bathroom appliances; home visits; patient and family education.”(Suggested by Philips et al, 2002)

providing the treatment will do exercises with you and may also give you exercises to do on your own or with a family member or friend. While results can vary from person to person, there is scientific evidence that many people who receive this therapy can have improved use of their weaker arm.
Are there any side effects or risks?
CIMT is usually done by a physical therapistIn charge of the “assessment and treatment of motor functioning, including motor control, strength and physical conditioning; balance, gait and mobility retraining; home and community visits; patient and family education regarding mobility and safety issues.” (Suggested by Philips et al, 2002)

at a rehabilitation centre or out-patient clinic. However, many of the exercises must be done outside of treatment time. Family members and friends can be very important in helping you do these exercises. Ask your therapist to give you and your friends/family specific information on exercises.
How long is the treatment period?
Intense, repetitive training of the weaker arm is usually given for 90 percent of waking hours (about 13 hours/day) for a 2-week period. This can be done in the clinic, at home, and wherever else it is safe to do so.
An alternative form of CIMT – modified CIMT – is done for fewer hours and possibly, for more weeks. Consult with your therapist or physician who will help you decide which is right for you – CIMT or mCIMT.
This treatment program requires a good deal of self-discipline and commitment. Individuals with strokeAlso called a “brain attack” and happens when brain cells die because of inadequate blood flow. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. 80% of cases are also know as a “schemic stroke”, or the formation of a blood clot in a vessel supplying blood to the brain.

Is constraint-induced movement therapy for me?
CIMT can be of benefit to those who have lost some of the use of their upper limb following strokeAlso called a “brain attack” and happens when brain cells die because of inadequate blood flow. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. 80% of cases are also know as a “schemic stroke”, or the formation of a blood clot in a vessel supplying blood to the brain.

Clinician Information
Note: When reviewing the findings, it is important to note that they are always made according to randomized clinical trial (RCT) criteria – specifically as compared to a control group. To clarify, if a treatment is “effective” it implies that it is more effective than the control treatment to which it was compared. Non-randomized studies are no longer included when there is sufficient research to indicate strong evidence (level 1a) for an outcome.
The effectiveness of Constraint-Induced Movement Therapy (CIMT) has been explored as an approach to reducing motor impairmentLoss of strength and coordination, decrease in arm or leg movement
and improving motor activity during functional tasks post-stroke. Fifty-one RCTs, 35 of high quality, 12 of fair quality and four of poor quality have examined the effectiveness of CIMT (restraint for 90% of waking hours and 6 hours of upper limb therapy per day for 2 weeks) or modified CIMT (mCIMT – whereby restraint and/or therapy is provided at a lesser intensity than CIMT) in comparison to traditional upper extremity (UE) therapy OR other forms of UE treatment. Studies have explored the use of CIMT or mCIMT at varying phases of strokeAlso called a “brain attack” and happens when brain cells die because of inadequate blood flow. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. 80% of cases are also know as a “schemic stroke”, or the formation of a blood clot in a vessel supplying blood to the brain.

The results from all reviews indicate a significant effect of CIMT, mCIMT or forced use therapy on arm motor function and impairment. The effect on disability is less conclusive, with Sirtori et al. (2009) reporting a moderate effect of CIMT, mCIMT or forced use therapy immediately post-intervention (but not 3 to 6 months post-intervention), Corbetta et al. (2010) reporting no significant effect of CIMT, mCIMT or forced use therapy on disability, and Shi et al. (2011) reporting a significant effect of mCIMT when disability is measured using the Functional Independence Measure, but not the Barthel Index. While all but two studies included in these three reviews are also reviewed on this website, differentiation of the studies according to the particular type of intervention (CIMT or mCIMT) and stage of strokeAlso called a “brain attack” and happens when brain cells die because of inadequate blood flow. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. 80% of cases are also know as a “schemic stroke”, or the formation of a blood clot in a vessel supplying blood to the brain.

(2009) concluded that restriction of the hand only, and a treatment protocol of no more than 30 hours indicate a significant effect sizeEffect size (ES) is a name given to a family of indices that measure the magnitude of a treatment effect. Unlike significance tests, these indices are independent of sample size. The ES is generally measured in two ways: as the standardized difference between two means, or as the correlation between the independent variable classification and the individual scores on the dependent variable. This correlation is called the “effect size correlation”.

We have reviewed all of the CIMT and mCIMT studies to identify outcomes according to stage of post-stroke recovery (acute, subacute, chronic). Patients less than one month post-stroke were identified as acute, those between 1 and 6 months post-stroke as subacute, and those greater than 6 months post-stroke as chronic. Intensity and duration of treatment were also important factors in influencing outcome, and these details are included in the review of each study.

One high quality RCT (Dromerick et al., 2009) examined the effect of mCIMT on depressionIllness involving the body, mood, and thoughts, that affects the way a person eats and sleeps, the way one feels about oneself, and the way one thinks about things. A depressive disorder is not the same as a passing blue mood or a sign of personal weakness or a condition that can be wished away. People with a depressive disease cannot merely “pull themselves together” and get better. Without treatment, symptoms can last for weeks, months, or years. Appropriate treatment, however, can help most people with depression.

This high quality RCT randomized patients with acute stroke to receive ‘standard’ mCIMT (shaping therapy for 2 hours/day and restraint 6 hours/day), ‘intensive’ mCIMT (shaping therapy for 3 hours/day and restraint 90% of waking hours) or conventional UE therapy. There were no significant between-group differences in depression (Geriatric Depression-15 Scale) at post-treatment (14 days) or follow-up (90 days).
Note: The terms ‘standard’ and ‘intensive’ mCIMT were defined by the authors of this study.

The first high quality RCT (Boake et al., 2007) randomized patients with acute strokeAlso called a “brain attack” and happens when brain cells die because of inadequate blood flow. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. 80% of cases are also know as a “schemic stroke”, or the formation of a blood clot in a vessel supplying blood to the brain. More to receive mCIMT or to receive intensive traditional upper extremity therapy (control group). The mCIMT group received 3 hours of therapy a day and wore a constraint 90% of waking hours. Dexterity was measured with the Grooved Pegboard Test at baseline, at 14-15 days (post-treatment) and at 3 to 4 months post-stroke (follow-up). No significant between-group difference in dexterity was found at either time point.
The second high quality RCTA randomized controlled trial (RCT) is an experimental design in which subjects are randomly assigned to a treatment group, or to a control (no treatment or alternative treatment) group. Effects of the experimental treatment are then compared statistically to results of the control treatment to determine effectiveness. More (Thrane et al., 2015) randomized patients with acute stroke to receive mCIMT or usual care. The mCIMT group received rehabilitation for 3 hours/day over 10 consecutive weekdays and wore a mitt on the nonaffected hand for 90% of waking hours. Dexterity was measured with the Nine Hole Peg Test at baseline, 2 weeks (post-treatment) and six months (follow-up). A significant between-group difference in dexterity was found at post-treatment in favour of the mCIMT group compared to the control group. This difference did not remain significant at 6-month follow-up.
Conclusion: There is conflicting evidence (level 4) from 2 high quality RCTs regarding the effect of mCIMT on dexterity. While one high quality RCT found that mCIMT is not more effective than intensive traditional therapy, a second high quality RCTA randomized controlled trial (RCT) is an experimental design in which subjects are randomly assigned to a treatment group, or to a control (no treatment or alternative treatment) group. Effects of the experimental treatment are then compared statistically to results of the control treatment to determine effectiveness.

Three high quality RCTs (Dromerick et al., 2000; Dromerick et al., 2009; Liu et al., 2016) examined the effects of mCIMT on functional independence in patients with acute stroke.
The first high quality RCT (Dromerick et al., 2000) randomized patients with acute strokeAlso called a “brain attack” and happens when brain cells die because of inadequate blood flow. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. 80% of cases are also know as a “schemic stroke”, or the formation of a blood clot in a vessel supplying blood to the brain. More to receive mCIMT plus conventional UE therapy or conventional UE therapy alone. The mCIMT group wore a padded mitt 6 hours a day for 14 days and received traditional therapy 2 hours a day. Functional independence in ADL was measured with the Barthel Index and 5 subscales of the Functional Independence Measure (FIM) at discharge from inpatient rehabilitation. A significant between-group difference in upper extremity dressing (FIM), was found in favour of mCIMT compared to conventional UE. There were no other significant between-group differences found in functional independence in ADL (Barthel Index; FIM eating, bathing, grooming and lower body dressing subscales) on discharge.

More to receive self-regulated mCIMT (SR-mCIMT), mCIMT or conventional rehabilitation. Participants in the mCIMT groups wore a restraint for 4 hours/day and all participants received individual training for 1 hour/day for 10 days. Upper extremity motor activity was measured at baseline, 2 weeks (post-treatment) and 4 weeks post-treatment (follow-up), using the MAL-AOU and MAL-QOM. At post-treatment there were significant differences in MAL-AOU and MAL-QOM scores in favour of mCIMT compared to conventional rehabilitation; differences did not remain significant at follow-up.
Note: Comparison of SR-mCIMT with conventional rehabilitation showed significant differences in MAL-AOU and MAL-QOM scores at post-treatment and follow-up. Comparison of SR-mCIMT with mCIMT showed significant differences in MAL-AOU scores in favour of SR-mCIMT at post-treatment, but differences did not remain significant at follow-up.
The fair quality RCT (Page et al., 2005) randomized patients with acute strokeAlso called a “brain attack” and happens when brain cells die because of inadequate blood flow. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. 80% of cases are also know as a “schemic stroke”, or the formation of a blood clot in a vessel supplying blood to the brain.

Conclusion: There is conflicting evidence (level 4) among 3 high quality RCTs. While 2 high quality RCTs reported that mCIMT (training 3 hours/day and restraint 90% of waking hours for 2 weeks) is not more effective than conventional rehabilitation, 1 high quality RCTA randomized controlled trial (RCT) is an experimental design in which subjects are randomly assigned to a treatment group, or to a control (no treatment or alternative treatment) group. Effects of the experimental treatment are then compared statistically to results of the control treatment to determine effectiveness. More found that mCIMT of less intensity (training 1 hour/day and restraint for 4-5 hours/day for 2 weeks) to be more effective than conventional rehabilitation.

One high quality RCT (Sawaki et al., 2008) and 1 fair quality RCT (Yoon et al., 2014) have examined the effect of CIMT on upper extremity (UE) motor function in patients with subacute stroke.
The high quality RCTA randomized controlled trial (RCT) is an experimental design in which subjects are randomly assigned to a treatment group, or to a control (no treatment or alternative treatment) group. Effects of the experimental treatment are then compared statistically to results of the control treatment to determine effectiveness. More (Sawaki et al., 2008) randomized patients with subacute stroke to receive CIMT or usual care. The CIMT group wore a padded mitt on the less-affected limb for at least 90% of waking hours and performed intensive therapy for 6 hours/day, 5 days/week for 2 weeks. Upper extremity motor function was measured using the Wolf Motor Function Test (WMFT) at baseline, 2 weeks (post-treatment) and at 4 months (follow-up). There was a significant between-group difference in only one measure of upper extremity motor function (WMFT grip strength), in favour of the CIMT group compared to the control group. There were no significant between-group differences in other measures of UE motor function (WMFT weight and time-based measures).
The fair quality RCT (Yoon et al., 2014) randomized patients with subacute strokeAlso called a “brain attack” and happens when brain cells die because of inadequate blood flow. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. 80% of cases are also know as a “schemic stroke”, or the formation of a blood clot in a vessel supplying blood to the brain. More to receive CIMT, CIMT + mirror therapy, or a control group that received occupational therapy and a self-exercise program. Upper extremity motor function was measured at baseline and 2 weeks (post-treatment) using the Wolf Motor Function Test (WMFT) and the Fugl-Meyer Assessment (FMA) – total score and Upper Extremity score (FMA-UE). At post-treatment there was a significant between-group difference in one measure of upper extremity motor function (WMFT), in favour of CIMT compared to the control group.
Note: At post-treatment the CIMT + mirror therapy group also showed significantly better WMFT scores than the control group.
Conclusion: There is moderate evidence (level 1b) from 1 high quality RCTA randomized controlled trial (RCT) is an experimental design in which subjects are randomly assigned to a treatment group, or to a control (no treatment or alternative treatment) group. Effects of the experimental treatment are then compared statistically to results of the control treatment to determine effectiveness. More and 1 fair quality RCTA randomized controlled trial (RCT) is an experimental design in which subjects are randomly assigned to a treatment group, or to a control (no treatment or alternative treatment) group.

Note: However the high quality RCT found a difference in WMFT grip strength in favour of CIMT vs. usual care; the fair quality RCTA randomized controlled trial (RCT) is an experimental design in which subjects are randomly assigned to a treatment group, or to a control (no treatment or alternative treatment) group. Effects of the experimental treatment are then compared statistically to results of the control treatment to determine effectiveness. More found differences in WMFT scores in favour of CIMT vs. OT and in favour of CIMT + mirror therapy vs. OT.

More to receive mCIMT or conventional occupational and physical therapy. The mCIMT group received 4 hours daily of therapy and wore a shoulder sling on the less-affected extremity for 90% of waking hours. Functional independence was measured using the modified Barthel Index (mBI) at baseline, 2 weeks (post-treatment) and 12 weeks (follow-up). There were no significant between-group differences in ADLs at either time point.

The third high quality RCTA randomized controlled trial (RCT) is an experimental design in which subjects are randomly assigned to a treatment group, or to a control (no treatment or alternative treatment) group. Effects of the experimental treatment are then compared statistically to results of the control treatment to determine effectiveness. More (Hammer & Lindmark, 2009b) randomized patients with subacute strokeAlso called a “brain attack” and happens when brain cells die because of inadequate blood flow. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. 80% of cases are also know as a “schemic stroke”, or the formation of a blood clot in a vessel supplying blood to the brain. More to a ‘forced use’ group or a control group that received conventional rehabilitation. The forced use group wore a sling to promote forced use of the paretic upper limb for up to 6 hours/day, 5 days/week for 2 weeks. Upper extremity motor function was measured using the FMA-UE, ARAT and Motor Assessment Scale at baseline, 2 weeks (post-treatment), 1 month (follow-up A) and 3 months (follow-up B). There were no significant between-group differences in upper extremity motor function at any time point.
The fourth high quality RCT (Brogardh et al., 2009b) randomized patients with subacute strokeAlso called a “brain attack” and happens when brain cells die because of inadequate blood flow. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. 80% of cases are also know as a “schemic stroke”, or the formation of a blood clot in a vessel supplying blood to the brain. More to a mCIMT group that wore a mitt on the less affected arm for 90% of waking hours, or a group that did not wear a mitt. Both groups received 3 hours of therapy for the affected arm for 12 days. Upper extremity motor function was measured using the modified Motor Assessment Scale and the Sollerman Hand Function Test (SHFT) at baseline, 2 weeks (post-treatment), 3 months and 12 months (follows-up). There were no significant between-group differences in upper extremity motor function at post-treatment or at follow-up (see Brogardh & Lexell, 2010).
The fifth high quality RCTA randomized controlled trial (RCT) is an experimental design in which subjects are randomly assigned to a treatment group, or to a control (no treatment or alternative treatment) group. Effects of the experimental treatment are then compared statistically to results of the control treatment to determine effectiveness. More (Brunner, Skouen & Strand, 2012) randomized patients with subacute strokeAlso called a “brain attack” and happens when brain cells die because of inadequate blood flow. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. 80% of cases are also know as a “schemic stroke”, or the formation of a blood clot in a vessel supplying blood to the brain. More to receive mCIMT or bimanual task-related training. The mCIMT group wore a restraint for 4 hours/day in addition to therapist-directed training for 4 hours/week and self-directed training for 2-3 hours/day for 4 weeks. Upper extremity motor function was measured at baseline, 4 weeks (post-treatment) and 3-month follow-up using the ARAT. There were no significant between-group differences in upper extremity motor function at any time point
The fair quality RCTA randomized controlled trial (RCT) is an experimental design in which subjects are randomly assigned to a treatment group, or to a control (no treatment or alternative treatment) group. Effects of the experimental treatment are then compared statistically to results of the control treatment to determine effectiveness. More (Page et al., 2001) randomized patients with subacute strokeAlso called a “brain attack” and happens when brain cells die because of inadequate blood flow. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. 80% of cases are also know as a “schemic stroke”, or the formation of a blood clot in a vessel supplying blood to the brain. More to receive mCIMT, conventional rehabilitation or no therapy. mCIMT comprised 30 minutes each of physiotherapy and occupational therapy 5 days/week for 10 weeks and restraint of the less affected arm 5 hours/day, 5 days/week for 10 weeks. Upper extremity motor function was measured using the ARAT, FMA and Wolf Motor Function Test (WMFT) at baseline and 10 weeks (post-treatment). The mCIMT group demonstrated substantial improvements in motor function whereas the other groups did not demonstrate substantial improvements on any measure of upper extremity motor function. Statistical data and between-group differences were not reported; accordingly this study is not included in determining level of evidence1a (Strong) : Well-designed meta-analysis, or 2 or more high quality RCTs (PEDro ≥ 6) showing similar findings 1b(Moderate): 1 RCT of high quality (PEDro ≥ 6) 2a (Limited): At least 1 fair quality RCT (PEDro = 4-5) 2b (Limited): At least one poor quality RCT (PEDro < 4) or well-designed non-experimental study (non-randomized controlled trial, quasi-experimental studies, cohort studies with multiple baselines, single subject series with multiple baselines, etc.) 3 (Consensus): Agreement by an expert panel or a group of professionals in the field or a number of pre-post studies all with similar results 4 (Conflicting): Conflicting evidence of 2 or more equally well-designed studies 5 (No evidence): No well-designed studies – only case studies/case descriptions or cohort studies/single subject series with no multiple baselines) More in the conclusion below.
Conclusion: There is strong evidence (level 1a) from 4 high quality RCTs that mCIMT or forced use therapy is not more effective than comparison interventions (conventional rehabilitation, no treatment, mCIMT training with no mitt use or bimanual task training) for improving upper extremity motor function among patients with subacute strokeAlso called a “brain attack” and happens when brain cells die because of inadequate blood flow. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. 80% of cases are also know as a “schemic stroke”, or the formation of a blood clot in a vessel supplying blood to the brain. More. However, 1 of these high quality RCTs found results in favour of mCIMT on one measure of upper extremity motor function (FMA) but not another (ARAT); and another highquality RCTfound that mCIMT is more effective than control therapy (e.g. conventional rehabilitation).
Note: Studies varied in constraint intensity (from 4 hours/day to 90% of waking hours), frequency of therapy (from 3 to 20 hours/week) and intervention duration (from 10 days to 10 weeks), which is likely to account for discrepancies in results among studies.
Note: One fair quality RCT demonstrated improved motor function at post-treatment for the mCIMT group but as statistical data and between-group differences were not reported, this study is not included in determining level of evidence1a (Strong) : Well-designed meta-analysis, or 2 or more high quality RCTs (PEDro ≥ 6) showing similar findings 1b(Moderate): 1 RCT of high quality (PEDro ≥ 6) 2a (Limited): At least 1 fair quality RCT (PEDro = 4-5) 2b (Limited): At least one poor quality RCT (PEDro < 4) or well-designed non-experimental study (non-randomized controlled trial, quasi-experimental studies, cohort studies with multiple baselines, single subject series with multiple baselines, etc.) 3 (Consensus): Agreement by an expert panel or a group of professionals in the field or a number of pre-post studies all with similar results 4 (Conflicting): Conflicting evidence of 2 or more equally well-designed studies 5 (No evidence): No well-designed studies – only case studies/case descriptions or cohort studies/single subject series with no multiple baselines) More.

Functional independence
Not effective
1B
One high quality RCT (Huseyinsinoglu, Ozdincler, & Krespi, 2012) investigated the effect of CIMT on functional independence in patients with chronic stroke. This high quality RCT randomized patients with chronic strokeAlso called a “brain attack” and happens when brain cells die because of inadequate blood flow. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. 80% of cases are also know as a “schemic stroke”, or the formation of a blood clot in a vessel supplying blood to the brain. More to receive CIMT or Bobath Concept therapy. Functional independence was measured using the Functional Independence Measure (FIM self cares and total score) at baseline and 2 weeks (post-treatment). There were no significant between-group differences in functional independence at post-treatment.
Conclusion: There is moderate (level 1b) evidence from 1 high quality RCTA randomized controlled trial (RCT) is an experimental design in which subjects are randomly assigned to a treatment group, or to a control (no treatment or alternative treatment) group. Effects of the experimental treatment are then compared statistically to results of the control treatment to determine effectiveness.

More. This high quality RCT randomized patients with chronic stroke to receive CIMT and affected-UE training or bimanual-UE training without restraint. Pinch strength and grip strength were measured by dynamometer at baseline and 2 weeks (post-treatment). At post-treatment there were significant between-group differences in pinch strength only, in favour of the CIMT group compared to the control group.
Conclusion: There is moderate evidence (level 1b) from one high quality RCT that CIMT is more effective than comparison interventions (bimanual upper extremity training) for improving pinch strength – but not grip strength – among patients with chronic stroke.
Kinematics (Upper extremity)

One pre-post study (Richards et al., 2008) investigated the effect of CIMT on upper extremity kinematics with 3 patients with chronic strokeAlso called a “brain attack” and happens when brain cells die because of inadequate blood flow. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. 80% of cases are also know as a “schemic stroke”, or the formation of a blood clot in a vessel supplying blood to the brain. More and ataxia. This pre-post study assigned patients to wear a mitten restraint during 90% of waking hours. Patients 1 and 2 received therapy 6 hours a day (CIMT) while patient 3 received therapy 3 hours a day (mCIMT). All participants demonstrated improved kinematic reaching values post-intervention, with no significant between-patient differences.
Note: Patients 1 and 2 improved on all kinematic measures: maximum velocity and time to maximum velocity increased, while index of curvature, number of peaks in the velocity profile, and trunk movement decreased. Participant 3 improved on some kinematic measures (smoother velocity profile, increased time to maximum velocity and decreased number of peaks in the velocity profile) but not all (decreased maximum velocity, increased index of curvature).
Conclusion: There is an insufficient evidence (level 5) comparing CIMT and control therapies on upper extremity kinematics in patients with chronic strokeAlso called a “brain attack” and happens when brain cells die because of inadequate blood flow. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. 80% of cases are also know as a “schemic stroke”, or the formation of a blood clot in a vessel supplying blood to the brain.

There were significant gains in MAL scores at post-treatment, in favour of CIMT + task-oriented training compared to task-oriented training alone.
The second fair quality RCT (Brogårdh & Sjülund, 2006) provided patients with chronic strokeAlso called a “brain attack” and happens when brain cells die because of inadequate blood flow. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. 80% of cases are also know as a “schemic stroke”, or the formation of a blood clot in a vessel supplying blood to the brain.

All participants demonstrated improved MAL-AOU and MAL-QOM scores after 2 weeks of CIMT, however no significant between-group differences were reported at 3 months.
Note: The authors reported that the small sample size was a limitation of this study.
A 4-year follow-up to this study (Brogårdh et al., 2009a) found a significant improvement in upper extremity motor activity from baseline to 4 years. However, comparison from post-treatment time points (2 weeks and 3 months) to 4-year follow-up revealed a significant decrease in motor activity.

Upper extremity motor activity was measured using the MAL-QOM subtest and the Upper Extremity Actual Amout of Use test (AAUT) at baseline, 2 weeks (post-treatment), 4 weeks (follow-up A) and 2 years (follow-up B). There was a significantly greater improvement in upper extremity motor activity at post-treatment, in favour of CIMT compared to the control group. No significant between-group differences were reported at follow-up time points.

One high quality RCT (Huseyinsinoglu, Ozdincler, & Krespi, 2012) has investigated the effect of CIMT on quality of movement of the upper extremity in patients with chronic stroke. This high quality RCT randomized patients with chronic stroke to receive CIMT or Bobath Concept therapy. At post-treatment (2 weeks) there was no significant between-group difference in upper extremity quality of movement (Motor Evaluation Scale for Arm in Stroke Patients).
Conclusion: There is moderate (level 1b) evidence from 1 high quality RCTA randomized controlled trial (RCT) is an experimental design in which subjects are randomly assigned to a treatment group, or to a control (no treatment or alternative treatment) group.

Sensory discrimination
Not effective
2a
One fair quality RCT (Brogårdh & Sjülund, 2006) examined the effect of CIMT on sensory discrimination in patients with chronic stroke. This fair quality RCT provided patients with a 2-week CIMT program, then randomized patients to prolonged mitt use for a further 3 months, or no further treatment. There were no significant within-group differences in sensory discrimination (Two-Point Discrimination Test) following 2 weeks of CIMT. Further, there were no significant between-group differences in sensory discrimination at 3 months.
Conclusion: There is limited evidence (level 2a) from 1 fairquality RCTthat CIMT does not improve sensory discrimination in chronic stroke. Further, the fairquality RCTfound that prolonged mitt wear is not more effective than control therapy (i.e. no treatment) for improving sensory discrimination in patients with chronic stroke.
Chronic phase: mCIMT vs. control or alternative interventions
One high quality RCT (Barzel et al., 2015), 1 poor quality RCT (Kim et al., 2008) and 1 quasi-experimental studyAn experimental study in which the participants are not randomized to receive treatments and as such the investigators lack control over allocation to interventions. This study design is inferior to a randomized controlled trial (RCT) but is valuable in answering research questions when an RCT is not possible either because of ethical constraints or logistic restraints.

More to receive mCIMT, bilateral arm therapy (BAT) or conventional therapy. mCIMT comprised use of a restrictive mitt for 6 hours/weekday. All groups received 2 hours of occupational therapy daily over the intervention period. Unilateral and bilateral reach kinematics were measured at baseline and 3 weeks (post-treatment) according to movement efficiency (normalized movement time – NMT), movement smoothness (normalized movement unit – NMU), peak velocity (PV) and movement strategies (percentage of movement time when peak velocity occurred – PPV). At post-treatment there was a significant between-group difference in unilateral and bilateral NMU in favour of the mCIMT group compared to the control group.
Note: There was also a significant between-group difference in unilateral and bilateral NMU and PV, in favour of the BAT group compared to the control group. There were no differences between groups for other kinematic measures.

A pre-post study without multiple baselines (Caimmi et al., 2008) tested the suitability of a new method of kinematic analysis for evaluating the effects of mCIMT in patients with chronic strokeAlso called a “brain attack” and happens when brain cells die because of inadequate blood flow. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. 80% of cases are also know as a “schemic stroke”, or the formation of a blood clot in a vessel supplying blood to the brain. More. The patients wore a splint on the less affected limb for approximately 80% of waking hours for 14 consecutive days and received 1 hour of physiotherapy and occupational therapy every weekday. Motor function was assessed at baseline and 2 weeks (post-treatment) using the WMFT and the Motricity Index upper extremity subtests. At post treatment the patients demonstrated significantly improved within-subject pre-post scores on the WMFT but not on the Motricity Index.
A pre-post study with multiple baselines (Dettmers et al., 2005) examined the effects of mCIMT in patients with chronic strokeAlso called a “brain attack” and happens when brain cells die because of inadequate blood flow. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. 80% of cases are also know as a “schemic stroke”, or the formation of a blood clot in a vessel supplying blood to the brain.

Upper extremity motor function was measured at baseline, 3 weeks (post-treatment) and at 6-month follow-up using the WMFT, Frenchay Arm Test, and grip strength. There were significant improvements on all measures of motor function from pre- to post-treatment, and results were retained at 6-month follow-up.

The first high quality RCT (Wu et al., 2007b) randomized patients between 3 weeks and 35 months since strokeAlso called a “brain attack” and happens when brain cells die because of inadequate blood flow. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. 80% of cases are also know as a “schemic stroke”, or the formation of a blood clot in a vessel supplying blood to the brain. More to receive mCIMT or neurodevelopmental therapy (NDT). Functional independence was measured at baseline and 3 weeks (post-treatment) using the Functional Independence Measure (FIM). There were significant between-group differences in functional independence at post-treatment, in favour of mCIMT compared to NDT.
The second high quality RCT (Batool et al., 2015) randomized patients who were 2 weeks to 3 months post-stroke to receive mCIMT or a motor relearning program. The mCIMT group wore a mitt during 2-hour training sessions, 6 times/week. Functional independence was measured at baseline and 3 weeks (post-treatment) using the Functional Independence Measure (FIM) – eating, grooming, bathing, dressing upper body, dressing lower body and total scores. There were significant between-group differences on all FIM domains except FIM – dressing upper body at post-treatment, in favour of mCIMT compared to the motor relearning program.

Range of motion
Not effective
1b
One high quality RCT (Khan et al., 2011) investigated the effect of mCIMT on upper extremity range of motion in patients with stroke. This high quality RCT randomized patients with subacute to chronic stroke to receive mCIMT, conventional neurological therapy, or therapeutic climbing. The mCIMT group received physiotherapy and occupational therapy for 5 hours/week while wearing a mitt, and an additional 5 hours/week of self-training of repetitive task-oriented activitiesAs defined by the International Classification of Functioning, Disability and Health, activity is the performance of a task or action by an individual. Activity limitations are difficulties in performance of activities. These are also referred to as function.
. Upper extremity active range of motion (shoulder flexion) was measured using a goniometer at baseline, 5 weeks (post-treatment) and 6-month follow-up. There were no significant between-group differences in active range of motion on shoulder flexion at any time point.
Conclusion: There is moderate evidence (level 1b) from 1 high quality RCT that mCIMT is not more effective than comparison interventions (conventional neurological therapy, therapeutic climbing) for improving upper extremity range of motion in patients with strokeAlso called a “brain attack” and happens when brain cells die because of inadequate blood flow. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. 80% of cases are also know as a “schemic stroke”, or the formation of a blood clot in a vessel supplying blood to the brain.
