Abstract: Systems and methods for recording data representative of, and reviewing and analyzing such data for, compliance by patients with prescribed use regimens of rehabilitation devices, such as a sling, are disclosed. Such devices comprise one or more sensors, a power source, and a communication system. The sensors track data indicative of the actual wear or use time of the rehabilitation device, which may be used to monitor compliance with physician recommended wear times. Adjustments may then be made to the prescribed use regimen, or physical adjustments may be made directly to the rehabilitation device.
