GRIND TEST

​• ​Test positioning

The client lies supine on a table with their shoulder abducted to 90-degrees and their elbow flexed to 90-degrees on the involved side.

The therapist grasps the client's elbow with one hand and the client's proximal humerus with the other hand.

​• ​Action

The therapist applies compression to the glenoid labrum while attempting to rotate the humeral head 360-degrees around the surface of the glenoid fossa.

​• ​Positive finding

A positive finding of a grinding or clunking sensation may be indicative of a glenoid labrum tear to the specific location, which is being compressed.

​• ​Special considerations & comments

​​This test should be done carefully, since the application of excessive pressure combined with rotation may further damage the glenoid labrum.
