Effectiveness of a Neoprene CMC Joint Orthosis

Study Overview
=================
Brief Summary
-----------------
Patients will be gathered via convenience sample from a hand therapy clinic. They will be provided with a neoprene commercially available orthosis free of charge. Baseline pain and function will be assessed using the VAS and Functional Index of Hand Arthropathies. Four weeks later, pain, function, and patient satisfaction with the device will be gathered using the Quebec User Evaluation of Assistive Technology questionnaire.

Detailed Description
-----------------
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.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Pain using the Visual Analog Scale (VAS) scale | Pain measured with VAS pain scale, measured from 1-10. 1 is the best and 10 is the worst | 1 month | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Hand osteoarthritis Function | Function measured with FIHOA.The FIHOA assesses hand OA-related functional impairment scoring from 0 (no functional impairment) to 30 points (maximal impairment).The total score ranges from 0 to 30, with a validated threshold of 5 able to distinguish between symptomatic and not symptomatic patients or controls. | 1 month | 
| Patient satisfaction with device: Quebec User Evaluation of Satisfaction with Assistive Technology | Measured with QUEST scale. The Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST 2.0) is a 12-item outcome measure that assesses user satisfaction with two components, Device and Services. Scores of 1 indicate dissatisfaction and scores of 5 indicate high satisfaction | 1 month |
