VALGUS STRESS TEST (WRIST AND HAND)
TEST POSITIONING
The therapist maintains stabilization of the proximal bone between the thumb and forefinger, and grasps the distal bone (usually the bones comprising a hinge joint).
ACTION
The therapist provides a valgus force to the joint, creating a fulcrum while attempting to "gap the joint".
POSITIVE FINDING
Any excessive gapping that is noted when compared to the uninvolved side may indicate a collateral ligament tear.
CONSIDERATIONS & COMMENTS
The therapist should perform this test with extreme care so no further damage is created with the valgus stress that is applied.
This test can also be performed at the metacarpophalangeal joint of the thumb, where excessive joint movement would indicate an ulnar collateral ligament tear, commonly referred to as "Skier's Thumb".
