A case having difficulty in tying with the forearm in the supinated position assuming a back-scratching motion: focus on shoulder range of motion

Abstract

We report a case of cervical disc hernia who found it difficult to scratch the back with the right hand due to pain. With a supinated forearm, although it was difficult to perform the tying movement with the right palm facing the back, this could be performed without pain. A difference was found in the shoulder extension movement when comparing the tying movements of the medial and supinated positions of the forearm. As a result of treatment focusing on the range of motion of right shoulder joint extension, the practical use of the tying movement in the supinated position of the forearm increased.
