Evaluation of the Effectiveness of Night Orthosis in Treating Women With Symptomatic Osteoarthritis in the Interphalangeal Joint of the Dominant Hand

Study Overview
=================
Brief Summary
-----------------
Evaluation of the effectiveness of using a night orthosis for II and III or fingers of the dominant hand in women diagnosed with symptomatic osteoarthritis compared to a control group.

Detailed Description
-----------------
Objective: To evaluate the effectiveness of using a night orthosis for II and III or fingers of the dominant hand in women diagnosed with symptomatic osteoarthritis compared to a control group. Methods: Through a randomized controlled clinical trial with blind assessment and follow-up of six months. Fifty-Two participants were randomized into two groups: group orthosis and control, and made a night orthosis II and or III fingers, thermoplastic will be used as a treatment for participants orthosis group. The participants underwent four evaluations at time 0, 45 days, 90 days and 180 days after its inclusion in the study. The variables studied were: the visual analog scale of pain, grip and pinch strength, questionnaires Cochin and Australian/Canadian Hand Osteoarthritis Index and functional Pick-up test.
