Click here to download a PDF version of this application. This app can be used for Carpal Tunnel Syndrome (CTS), which is caused by compression of the median nerve travelling through the carpal tunnel. CTS affects the hands since it is an upper limb neuropathy that results in motor and sensory disturbance of the median nerve. Simply move the app over the area where you feel the most pain. These directions may be different than the video; feel free to experiment. If you're still not getting relief we recommend you contact one of our Rock Docs for medical consultation.
