Effectiveness of a Neoprene CMC Joint Orthosis

Patients with the diagnosis of carpometacarpal osteoarthritis that are receiving hand therapy will be recruited for the study. Baseline measurements will include usual pain over the past week, current pain, and worst pain experienced over the past week using the VAS pain scale. Hand function will be assessed using the Functional Index of Hand Arthropathies measure. The patients will be provided with a free neoprene hand orthosis (Hely and Weber CMC controller). They will be instructed to wear the device as needed for pain. After 1 month, the investigators will call the patient to assess pain, function, and satisfaction with the device using the Quebec User Evaluation of Assistive Technology Questionnaire.
