Summary

Subjects will receive 30 treatments with AMES, to the proximal arm which has been affected by a chronic stroke.

Detailed description

This study seeks to determine whether 30 treatments with AMES, to the proximal affected arm of subjects with chronic stroke, will improve subjects' proximal arm active range-of-motion. We hypothesize that the combination of assisted movement, torque biofeedback, and muscle vibration will reduce impairment (i.e., increase strength and range-of-motion; decrease inappropriate patterns of muscle contraction) and, thereby, lead to more accurate reaching with the proximal arm.

Conditions

• Stroke
• Cerebrovascular Accident

Interventions

Type	Name	Description
DEVICE	30 PAAD treatments	Subjects will don a shirt with pockets at the elbow and shoulder in each of which a muscle vibrator is located. The subject will then place the affected arm in the PAAD. The PAAD will range the affected arm, at the shoulder in the adduction-abduction direction, and at the elbow in the flexion-extension direction. The subject will assist volitionally this motion, and visual feedback of the level of their assistive torque will be provided along with a target torque level. The muscle vibrators will alternate from one side of each of the 2 joints to the other as the motion reverses, vibration always being applied to the lengthening muscles. This treatment will last 30 min in each session.
