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

Not Applicable

Completed

• Conditions: Arm Weakness as a Consequence of Stroke
• Interventions: Device: compliant support

• Registration Number: NCT03867838
• Lead Sponsor: Stanford University

Brief Summary

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.

Arm && Interventions

Group	Intervention	Description
Stroke survivors	compliant support	Stroke survivors with upper extremity motor impairments

Primary Outcome Measures

Name	Time	Method
Percent Change From Baseline in Reachable Workspace	baseline, while using support device, and 30 minutes following removal of support device (up to 4 minutes per assessment)	Reachable workspace was measured using a PhaseSpace motion capture system, recorded as an area (in square meters).

Secondary Outcome Measures

Name	Time	Method
Percent Change From Baseline in Biceps Activation	baseline and while using support device (up to 10 seconds per assessment)	Biceps activation measured using surface electromyography during an isometric hold to approximate the contributions of erroneous flexor synergies.
