Finkelstein's test is used to diagnose De Quervain's tenosynovitis in people who have wrist pain. To perform the test, the examining physician or therapist grasps the thumb and ulnar deviates the hand sharply, as shown in the image. If sharp pain occurs along the distal radius (top of forearm, close to wrist; see image), de Quervain's tenosynovitis is likely.〔(De Quervain’s Tenosynovitis: Finkelstein’s Test )〕 Other practitioners use a modified Eichhoff's test, below, and ask their patients to flex their thumb and clench their fist over the thumb before ulnar deviation, but with ulnar deviation performed by the practitioner.〔Walker, Julia J., & Dave, Shashank J. (2009). "Road Cycling Injuries". In Buschbacher, Ralph M., Prahlow, Nathan D., & Dave, Shashank J., ''Sports Medicine and Rehabilitation'' (2nd Edition, p 113). Philadelphia, PA: Lippincott Williams & Wilkins.]〕 Eichhoff's test is commonly confused with Finkelstein's test. However the Eichhoff's test may produce false positive results, while a Finkelstein's test performed by a skilled practitioner is unlikely to produce a false positive.〔http://jhs.sagepub.com/content/39/3/286〕 ==Purpose== Finkelstein's test is one way to determine if there is tenosynovitis in the abductor pollicis longus and extensor pollicis brevis tendons of the wrist. These two tendons belong to the first dorsal compartment. *First dorsal compartment: abductor pollicis longus and extensor pollicis brevis. *Second dorsal compartment: extensor carpi radialis longus and extensor carpi radialis brevis. *Third dorsal compartment: extensor pollicis longus. *Fourth dorsal compartment: extensor digitorum and extensor indicis. *Fifth dorsal compartment: extensor digiti minimi. *Sixth dorsal compartment: extensor carpi ulnaris. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Finkelstein's test」の詳細全文を読む スポンサード リンク
