When the first carpometacarpal joint of wrist is immobilized using an orthosis to combat effects osteoarthritis, atrophy thenar muscles may occur.The aim this study was evaluate muscle diameter and cross-sectional area, function, pain, before after being supplied with in patients grades 1 2 osteoarthritis compared a control group.Randomized clinical trial.A total 25 volunteer were randomized into two groups (an group group) randomization table. A visual analog scale, Michigan Hand Questionnaire, ultrasound used measure specific areas at baseline 4 weeks both groups.Mean scale pain scores decreased by 20% splinting, while those 3%. Changes significantly different between ( p = 0.001). There no significant difference either Questionnaire score or area.A large effect on perceived observed splint use. Differences treatment found regard areas, but these not significant. Clinical relevance Custom-made splints be recommended for osteoarthritis. Moderate non-significant areas.
