Summary of Condition:
Tenosynovitis is an inflammation of the synovial sheaths covering the tendons.  It is seen frequently as a result of trauma, rheumatoid arthritis, or infection.  It is frequently caused by trauma to the wrist and prominent swelling usually occurs.  Tenderness on pressure over the tendon sheath is a constant finding.  The problem may involve the thumb muscles including the abductor pollicis and extensor pollicis brevis (de QuerVain’s Teno Synovitis), which produces a stenosis in the common osteofibrous canal.  Pain frequents on moving the wrist and thumb, especially with opposition of the thumb to the little finger and ulnar flexion of the wrist.  Historically, there is a short period of injection and immobilization.

Benefits of AIS on Condition:
Upon medical approval, specific AIS stretching of the wrist and hand is performed very carefully.  An active AIS strength program with mild resistance using a wrist roller stick, a soft ball and a rubber band in isolated thumb, finger and wrist movements.
