Robot-Assisted Arm Training in Stroke Individuals With Unilateral Spatial Neglect: A Pilot Study

Area of Science:

• Neurorehabilitation
• Robotics in Medicine
• Stroke Recovery

Background:

• Unilateral spatial neglect is a common post-stroke deficit.
• Robot-assisted arm training (RAT) offers intensive, adaptive therapy.
• The efficacy of RAT for unilateral spatial neglect post-stroke is underexplored.

Purpose of the Study:

• To investigate the effects of RAT on unilateral spatial neglect.
• To assess RAT's impact on arm motor function, daily living activities, and social participation after stroke.

Main Methods:

• Pilot randomized controlled trial involving stroke patients with unilateral spatial neglect.
• Intervention group received RAT; control group received standard care.
• Training involved 45-min sessions, 5 days/week for 4 weeks.

Main Results:

• RAT was feasible and safe.
• Significant improvements observed in neglect symptoms (BIT-C), upper extremity function (FMA-UE), and social participation (WHODAS 2.0) in the RAT group.
• No significant differences between groups for CBS and MBI scores.

Conclusions:

• Preliminary evidence supports RAT for unilateral spatial neglect remediation post-stroke.
• RAT may improve neglect symptoms, motor function, and social participation.
• RAT did not demonstrate significant improvements in activities of daily living.
