DeQuervain's tenosynovitis is characterized by pain on the pain on the radial (thumb) side of the wrist problems with thumb function. At this point, the standard care is to change daily activities, use a thumb brace, and the possible use of painkillers. There is a difference in opinion among physical therapists about how to use the splint in the treatment of DeQuervain tenosynovitis. Some physicians tell patients to wear the brace at all times while other therapists encourage patients to exercise and use the brace as needed. Both approaches to using the splint are accepted as standard. The purpose of this study is to test and evaluate these two ways of splinting and assess which one is better for patients with DeQuervain tenosynovitis.
