Effects of Motor Imagery on Trapeziometacarpal Osteoarthritis in Women During the Postoperative Immobilization Period

Study Overview
=================
Brief Summary
-----------------
The aim of this study is to verify whether after trapeziometacarpal osteoarthrosis surgery and during the period of immobilization immediately after it, applying motor imagery, improvements are achieved on pain, strength, edema and / or inflammation, function and the joint range, accelerating the recovery process.

Detailed Description
-----------------
Motor imagery (IM) consists of a complex cognitive operation by which an action is simulated without doing it physically. Many studies support the usefulness of motor imaging in rehabilitation after manual surgery. An approach based on motor imagery may be useful in trapeziometacarpal osteoarthritis, and may be used to promote motor recovery after surgical treatment.
