Introduction
Bilateral Arm Training (BAT) comprises repetitive practice of bilateral arm movements in symmetrical or alternating patterns. Traditionally, bilateral arm training was performed by linking both hands together so that the less-affected limb facilitated passive movement of the affected limb. Variations of bilateral arm training include bilateral isokinematic training (spatiotemporally identical active movements performed during functional tasks), use of mechanical devices to drive passive or active movement of the affected limb, or bilateral arm training with rhythmic auditory cueing or electromyography (EMG) stimulation.
The use of bilateral arm training in 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. rehabilitation is based on the assumption that symmetrical bilateral movements activate similar neural networks in both hemispheres, promoting neural plasticity and cortical repair that result in improved motor control in the affected limb. Bilateral arm training is suitable for use as an adjunct to other upper limb interventions and should involve repetitive movement during performance of novel, functional tasks.

What is bilateral arm training (BAT)?
Bilateral Arm Training is a type of rehabilitation that uses symmetrical (same) or alternating (opposite) movements of both arms. 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. can disrupt the messages that are sent from your brain to your muscles; this can affect strength and movement in your arm/hand. Moving your arms during Bilateral Arm Training might send feedback to both sides of the brain (the affected and the non-affected hemispheres), which might increase brain activity. This in turn might help rebuild the side of the brain 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., and the pathways in the brain that cause movement in the affected arm.
What is Bilateral Arm Training used for in people with stroke?
The goal of Bilateral Arm Training is to improve strength and use of the arm that was 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..
Are there different kinds of bilateral arm therapies?
Traditionally, Bilateral Arm Training was done by linking both hands together so that the less-affected arm helped to move the affected arm.
Variations of BAT include:
- Isokinematic BAT – identical active movements of both arms
- BAT with robotic or mechanical devices – the device drives the movement of the affected arm
- BAT with rhythmic auditory cueing – music or a metronome are used to guide arm movements
- BAT with electromyography (EMG) stimulation – an electrical stimulation is applied to the muscles of the affected arm during arm movements.
Does Bilateral Arm Training work for stroke?
The use of Bilateral Arm Training has been examined using high quality research studies. It was shown to improve arm function in some patients after 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.. In particular, BAT and BAT with rhythmic auditory cueing were useful for 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 than 6 months after 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.) to improve movement, strength and function of the affected arm. It is important to note that results can vary from person to person.
What can I expect?
During traditional Bilateral Arm Training, you will practice repetitive and intensive exercises of both arms for 1-2 hours per day, 2-5 times per week for 2 weeks or more. In addition, your 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)
or 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)
might choose other types of BAT (see above) to assist in moving and strengthening the affected arm. Your therapist will discuss with you the regime and type of BAT that is most suitable for you.
Who provides the treatment?
Bilateral Arm Training is usually administered 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 at an out-patient clinic.
How long is the treatment period?
Bilateral Arm Training treatment regimens vary. Sessions may range from 45 minutes to 2 hours, from 2 to 5 times per week, and for 1 to 6 weeks. On average, it is delivered for 1 hour, 3 times per week for 4 weeks.
Are there any side effects or risks?
Bilateral Arm Training is usually administered by a trained health professional at a rehabilitation clinic. Your therapist will monitor your reactions to this therapy closely. It is important to report any feelings of discomfort or pain (such as pain at the shoulder of the affected arm). Your therapist will adjust the intensity and the duration of therapy according to your ability, endurance and progress.

Clinician Information
Note: When reviewing the findings, it is important to note that they are always made according to randomized clinical trial (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.) 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 moderate-strong evidence (Level 1b-1a) for an outcome.
A total of 40 studies (20 high quality RCTs, ten fair quality RCTs, three poor quality RCTs and seven non-randomized studies) that investigate the use of bilateral arm therapy in post-stroke upper limb rehabilitation were reviewed.

Types of bilateral arm training have been differentiated according to the following categories: generic bilateral arm training; device-driven bilateral arm training (passive/active movements using mechanical devices); bilateral arm training with rhythmic auditory cueing (BATRAC); and bilateral arm training with electromyography (EMG).
Overall, results indicate that bilateral arm training is not more effective than comparison therapies and is typically less effective than constraint induced movement therapies. Recent systematic reviews by Coupar et al., (2010) and van Delden et al (2012) drew similar conclusions.

Five high quality RCTs (van der Lee et al., 1999; Lin et al., 2009; Lin et al., 2010; Wu et al., 2011; Wu et al., 2012), two fair quality RCTs (Shim & Jung, 2015; Sethy et al., 2016) and one poor 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. (Wu et al., 2010) investigated the effect of bilateral arm training on upper extremity motor activity 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..
The first high quality RCT (van der Lee et al., 1999) randomized patients to receive bilateral arm training based on neurodevelopmental techniques or forced use therapy. Upper extremity motor activity was measured by the Motor Activity Log – Amount of Use (MAL-AOU), Quality of Movement (MAL-QOM) and Problem (MAL-Problem) scores at post-treatment (3 weeks) and follow-up (6 weeks, 6 months, 12 months). No significant between-group differences were found at any time points.
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. (Lin et al., 2009) randomized patients to receive bilateral arm training, modified constraint induced movement therapy (mCIMT) or dose-matched conventional rehabilitation comprising neurodevelopmental therapy and compensatory practice of functional tasks. Upper extremity motor activity was measured by MAL-AOU and MAL-QOM scores at post-treatment (3 weeks). Significant between-group differences on both upper extremity motor activity measures were found, favouring mCIMT vs. bilateral arm training. There were no significant differences between bilateral arm training and conventional rehabilitation.
Note: There were significant differences on both upper extremity motor activity measures, favouring mCIMT vs. conventional rehabilitation.
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. (Lin et al., 2010) randomized patients to receive bilateral arm training using functional tasks or occupational therapy upper limb training using neurodevelopmental techniques. Upper extremity motor activity was measured by the MAL-AOU and MAL-QOM at post-treatment (3 weeks). No significant between-group differences were found.
The fourth 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. (Wu et al., 2011) randomized patients to receive bilateral arm training, mCIMT or conventional rehabilitation. Upper extremity motor activity was measured by the MAL-AOU and MAL-QOM at post-treatment (3 weeks).

Effects of the experimental treatment are then compared statistically to results of the control treatment to determine effectiveness. (Wu et al., 20122) randomized patients to receive therapist-led bilateral arm training, robot-assisted bilateral arm training or conventional rehabilitation. Upper extremity motor activity was measured by the MAL-AOU and MAL-QOM at post-treatment (4 weeks). No significant between-group differences were found between therapist-led bilateral arm training vs. conventional rehabilitation, or between therapist-led vs. robot-assisted bilateral arm training.

Effects of the experimental treatment are then compared statistically to results of the control treatment to determine effectiveness. (Shim & Jung, 2015) randomized patients to receive bilateral or unilateral arm training using functional tasks. Upper extremity motor activity (paretic/non-paretic side: amount, intensity) was measured by Actisleep accelerometry at post-treatment (6 weeks). Significant between-group differences were found on both measures of upper extremity motor activity of the paretic limb (amount; intensity: reduced sedentary activity, increased moderate activity), favouring bilateral vs. unilateral arm training.
The second 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.

One non-randomized study (Whitall et al., 2000) investigated the use of bilateral arm training with rhythmic auditory cueing (BATRAC) on range of motion in the upper extremity 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.. This non-randomized study assigned patients to receive BATRAC. Active and passive range of motion (aROM, pROM) at the shoulder (flexion, extension, abduction, adduction), elbow (flexion, extension), wrist (flexion, extension) and thumb (opposition) was measured at post-treatment (6 weeks) and follow-up (2 months). At post-treatment significant improvements in shoulder aROM (extension only), wrist aROM/pROM (flexion only), and thumb aROM (opposition) were found. At follow-up, improvements in wrist pROM (flexion only) and thumb aROM (opposition) were maintained.
Conclusion: There is limited evidence (Level 2b) from one non-randomized study that BATRAC is not effective for improving upper extremity range of motion 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..

Two high quality RCTs (Luft et al., 2004; Whitall et al., 2011) and one non-randomized study (Whitall et al., 2000) investigated the effect of bilateral arm training with rhythmic auditory cueing (BATRAC) on upper extremity strength 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..
The first 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. (Luft et al., 2004) randomized patients to receive BATRAC or dose-matched upper limb exercises based on neurodevelopmental techniques. Strength of the paretic shoulder and elbow was measured by a dynamometer at post-treatment (6 weeks). No significant between-group difference was found.
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. (Whitall et al., 2011) randomized patients to receive BATRAC or dose-matched unilateral therapeutic exercises based on neurodevelopmental techniques. Isometric shoulder strength (flexion/extension) and isokinetic elbow (flexion/extension) and wrist (flexion/extension) strength of the paretic/non-paretic limbs were measured by dynamometer at post-treatment (6 weeks) and at follow-up (4 months). No significant between-group differences in shoulder strength were found at either time point. Significant between-group differences in strength of the non-paretic elbow (flexion only) and non-paretic wrist (flexion only) were found at post-treatment, favouring BATRAC vs. neurodevelopmental techniques. Conversely, a significant between-group difference in strength of the paretic wrist (extension only) was found, favouring the neurodevelopmental approach vs. BATRAC. Differences remained significant at follow-up.
One non-randomized study (Whitall et al., 2000) assigned patients to receive BATRAC. Isometric strength of the paretic/non-paretic shoulder, elbow and wrist (flexion/extension) was measured at post-treatment (6 weeks) and follow-up (2 months). At post-treatment there were no significant changes in shoulder or elbow strength, but there was a significant improvement in paretic wrist strength (flexion only). At follow-up there was a significant improvement in non-paretic elbow strength (flexion only) and non-paretic wrist strength(extension).
Conclusion: There is strong evidence (Level 1a) from two high quality RCTs that BATRAC is not more effective than a comparison intervention (neurodevelopmental techniques) in improving paretic upper extremity strength (shoulder, elbow, wrist).
Note: BATRAC was more effective than neurodevelopmental techniques in improving non-paretic wrist and elbow strength, whereas the neurodevelopmental approach was more effective than BATRAC for improving paretic wrist strength. Furthermore, a non-randomized study found significant short-term improvements in paretic wrist strength (flexion only), and significant long-term improvements in non-paretic elbow strength (flexion only) and non-paretic wrist strength (extension), following a BATRAC.

One non-randomized study (Hijmans et al., 2011) investigated the effect of bilateral video game training on upper extremity motor function in patients with chronic stroke. This non-randomized design study assigned patients to receive unilateral mouse-based computer game training using the less-affected hand (phase 1), then a washout period of no training (phase 2), then bilateral video game training using the CyWee Z game controller (phase 3). Upper extremity motor function was measured by the Fugl-Meyer Assessment – Upper Extremity (FMA-UE), the Wolf-Motor Function Test (WMFT), and the Disabilities of Arm Shoulder and Hand (DASH) at baseline and following phase 1 (unilateral training, 2.5 weeks), phase 2 (washout period, approx. week 5) and phase 3 (bilateral training, 7.5 weeks). A significant improvement was found in one measure of upper extremity motor function (FMA-UE) from baseline to phase 3.
Conclusion: There is limited evidence (Level 2b) from one non-randomized study that bilateral video game training is effective for improving upper extremity motor function 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..

Movement kinematics (NMT, NMU, NTD, trunk contribution slope for the middle part during unilateral and bilateral movement, angular changes of shoulder flexion during unilateral and bilateral movements) were measured at post-treatment (4 weeks). Comparison of robot-assisted bilateral arm training vs. conventional rehabilitation revealed significant differences (angular changes of normalized shoulder flexion during unilateral and bilateral movements), favouring robot-assisted bilateral arm training. Comparison of robot-assisted bilateral arm training vs. therapist-led bilateral arm training revealed a significant difference in one variable (angular changes of normalized shoulder flexion during unilateral movements), favouring robot-assisted bilateral arm training.

Movement kinematics (NMT, NMU, trunk contribution, slope start/mid during unilateral and bilateral movements) were measured at post-treatment (4 weeks). Comparison of bilateral vs. unilateral robot-assisted arm training revealed a significant between-group difference for one variable (slope start during bilateral movement), favouring robot-assisted bilateral arm training. There were no significant differences between robot-assisted bilateral arm training and conventional rehabilitation.
Note: Comparison of robot-assisted unilateral arm training vs. conventional rehabilitation revealed a significant between-group difference for one measure (slope mid during bilateral movement), favouring conventional rehabilitation.
The non-randomized study (Chang et al., 2007) assigned patients to receive robot-aided bilateral training using a bilateral force-induced isokinetic arm movement trainer (BFIAMT) and conventional rehabilitation. Reaching movement kinematics (movement time, peak velocity, percentage of time to peak velocity, normalized jerk score) were measured at post-treatment (8 weeks) and follow-up (16 weeks). Significant improvements in all reaching movement kinematics were found at post-treatment, but these did not remain significant at follow-up.
Conclusion: There is strong evidence (level 1a) from three high quality RCTs that device-driven bilateral arm training is more effective than comparison interventions (conventional upper limb rehabilitation using neurodevelopmental techniques, conventional rehabilitation,therapist-led bilateral arm training, or robot-assisted unilateral arm training) for improving 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..

A significant between-group difference (FMA-UE Proximal score only) was found at mid-treatment and at post-treatment, favouring bilateral robot-assisted movement training vs. neurodevelopmental techniques. This difference was not maintained at 6-month follow-up.

Wrist strength (flexion/extension) was measured at baseline and at post-treatment (4 weeks). No significant improvement was reported from baseline to post-treatment.
The second non-randomized study (Sampson et al., 2012) assigned patients with subacute/chronic stroke to receive bilateral arm training using the BUiLT bilateral arm trainer. Isometric strength at the shoulder (flexion, extension, abduction, external/internal rotation) and elbow (flexion/extension) was measured by dynamometer at post-treatment (6 weeks). Improved strength at the shoulder and elbow were reported, however statistical data was not provided.
