SPECIAL TESTS FOR THE WRIST AND HAND SPECIAL TESTS FOR THE WRIST AND HAND SPECIAL TEST: Collateral Ligament Test of Fingers STRUCTURE: Collateral Ligament of MCP joint (can be repeated for PIP and DIP with finger in extension). POSITION: The patient is seated with the wrist in neutral position; the MCP is in 90 degrees of flexion (this tightens the collateral ligaments).. The therapist is standing/ sitting with the thumb of the operating hand on the radial side of the proximal phalanx of patient’s digit. APPLICATION: POSITIVE SIGN: REFERENCE: Perform a varus force to phalanx distal to MCP; repeat with a valgus force. Gapping/instability at MCP joint. A. B. C.

The therapist moves the proximal interphalangeal joint into flexion. The patient's metacarpophalangeal joint is then placed in slight flexion and the therapist moves the interphalangeal joint into flexion. Metacarpophalangeal joint in flexed position; test is positive when the interphalangeal joint will not flex. If the metacarpophalangeal joint and interphalangeal joint will not flex, then the intrinsic muscle is tight or there is a contracture of the joint capsule. If the metacarpophalangeal joint is slightly flexed and the proximal interphalangeal joint will flex then the intrinsics are tight. The proximal phalangeal joint will not flex if the capsule is tight.

The patient remains passive throughout test. The therapist is sitting or standing. The patient’s proximal interphalangeal joint is held in a neutral position by the therapist. The therapist's thumb is on the palmar surface of the proximal interphalangeal space. The therapist's index finger is on the dorsal surface of the phalanx between the proximal and distal joint to maintain neutral position. The distal interphalangeal joint is flexed by the therapist. Distal Interphalangeal joint does not flex because the retinacular (collateral) ligaments or capsule is tight. Second Part of Retinacular Test: (to differentiate between capsule or ligaments) POSITION: The patient is sitting.The therapist is sitting or standing. APPLICATION: The therapist flexes the proximal interphalangeal joint of the patient (to relax the retinaculum). The therapist flexes the distal interphalangeal joint. POSITIVE SIGN: Distal interphalangeal joint flexes Retinacular ligaments are tight and the capsule is normal. If the distal interphalangeal joint does not flex then the capsule is contracted.

The patient is sitting. The therapist is sitting or standing. APPLICATION: The therapist stabilizes the metacarpophalangeal and interphalangeal joints in extension. The patient then flexes his finger at the distal interphalangeal joint. POSITIVE SIGN: If the distal interphalangeal joint flexion occurs then the tendon iS functional (figure A). A positive test shows the distal interphalangeal joint does not flex (figure).

The patient is seated with the hand pronated, while making a fist with the thumb tucked inside the fist.The therapist is standing alongside the patient using one hand to stabilize the patient’s forearm. While stabilizing the wrist / forearm of the patient, passively gently force the wrist into ulnar deviation. Significant pain over the radial styloid which may indicate stenosing tenosynovitis.

The patient is sittingThe therapist is sitting/standing APPLICATION: The radial and ulnar arteries are tested separately. The test can determine which artery supplies the most blood to the hand. The patient actively opens and closes the hand several times as quickly as possible. The patient's hand is kept closed tightly on the final squeeze. This allows for the venous blood to be removed from the palm. The therapis'ts thumb is placed over the patient's radial artery and occludes the artery. The therapist's index and middle finger are placed over the patient's ulnar artery to occlude the artery simultaneously. The therapist maintains the pressure over the arteries. The palm will appear pale. The patient is then instructed to open his hand. The therapist releases 1 artery and maintains pressure on the opposite artery. The test is repeated for the opposing artery. The test is compared to the contralateral hand. POSITIVE SIGN: The hand remains pale or the hand flushes slowly. Normally the hand will flush immediately.

The patient is sitting. Therapist is sitting/standing. APPLICATION: The patient actively opens and closes the hand several times as quickly as possible to remove the venous blood from the palm. The hand is kept tightly closed on the final squeeze. The patient's hand is kept in a fist. The therapist places his thumb and index finger on the sides of the base of the involved finger. Pressure is applied by the therapist on the digital arteries, pressing the arteries to the bone, occluding the arteries. The finger should be pale from the occlusion of the arteries. The patient open his hand and pressure is released by the therapist of one of the digital arteries. The test is repeated for the opposite digital artery of the same finger. The test should also be repeated for the same finger of the opposite hand. POSITIVE SIGN: The finger normally flushes when pressure is released from the artery. A positive test would reveal a pale finger or a slow flushing affect.

Ulnar nerve paralysis. The patient is sitting. The therapist is sitting or standing. APPLICATION: Place a piece of paper between the patient’s index finger and thumb at the level of the metacarpalphalangeal joints and have the patient squeeze hard. The therapist pulls the paper.

This distance is the Threshold for Discrimination. POSITION: The patient is sitting with the hand supported by a hard surface. The therapist is sitting or standing APPLICATION: The therapist simultaneously applies pressure on two adjacent points of the patients fingertips with a paper clip, 2 point discriminator, or caliper. The pressure is applied either in a longitudinal or perpendicular direction to the long axis of the finger. The therapist must make sure the two points touch the skin simultaneously. No blanching of the skin should occur when points are tested. The distance between the two points should be increased or decreased depending on the patients response. The patient shouldnot see the area being tested. POSITIVE SIGN: Normal distance between two points: less than 6 mm -Fair distance between two points: 6 mm to 10 mm -Poor distance between two points : 11 mm to 15 mm This test can be useful in determining the discrimination necessary to perform certain tasks: -Winding a watch: -Sewing: -Handling precision tools: -Gross tool handling: REFERENCE: 6 mm discrimination 6-8 mm discrimination 12 mm discrimination > 15 mm discrimination C. p. 195 Copyright © 1998 by The Ola Grimsby Institute • 1.800.646.6128 WRT • 17 NOTES WRT • 18 Copyright © 1998 by The Ola Grimsby Institute • 1.800.646.6128
