What is Teres Test?
The teres test indicates contracture of the teres major muscle. The teres major muscle functions as an internal rotator of the humerus.
The procedure of Performing the Teres Test
Position of the patient – The patient will be in a relaxed and standing position.
Position of the examiner – The examiner evaluates the position of the patient’s hands from behind.
Test Results of the Teres test
If there is a contracture present, the palm of the affected or tested hand will face backward compared to the contralateral hand (non-tested hand).
Therefore, with the patient standing in a relaxed position, if the palm of the affected or tested hand will face backward, such a finding suggests contracture of the teres major muscle.
