<prompt> Lift -off test is done to assess the function ofSupraspinatus muscleInfraspinatus muscleTeres minorSubscapularis muscle  <response>: In this test,the patient is asked to stand and place one arm behind his her back with the dorsum of the hand resting against the mid-lumbar spine. The examiner then lifts the patient;s hand off the back and the patient is told to hold it there. Inability to do this signifies subscapularis weakness,possibly due to rupture. A drawback is that the test calls for full passive internal rotation,so it cannot be used if internal rotation is painful or restricted. Ref: Maheshwari and Mhaskar 6e pg 95
