Increase upper extremity ROM through positioning techniques including prolonged stretch, tone management, and shoulder support
Capacity to facilitate elbow flexion, internal/external shoulder rotation, abduction, wrist extension.
Wear schedule for device
> 2 hours prolonged stretch (Ada et al., 2005)
Continual assessment of fit to ensure
progress and comfort (ie. edema, pressure,
