Effects of a Compliant Arm Support on Post-stroke Upper Extremity Range of Motion

Effects of Post-Stroke Upper Extremity Assistance

The aim of this study is to show that a wearable compliant arm support consisting of inflatable bladders with adjustable straps to connect them to the waist and arm can meaningfully increase the reachable workspace of persons with post-stroke arm weakness.

Inclusion Criteria:

• greater than 6 months post-stroke
• passive abduction to 90 degrees at shoulder
• reduced active (retro)flexion/extension at shoulder when abducted to 90 degrees
• reduced active flexion/extension at elbow

Exclusion Criteria:

• unable to give informed consent
• unable to comprehend and follow instructions
• have a condition (other than stroke) affecting sensorimotor function
• show evidence of unilateral spatial neglect
• unable to sit in a chair without armrests for 2 hours
