Stand or sit. Position bent arms up to sides; elbows bent shoulder height with wrists above elbows.
Pull elbows back behind shoulders as far as possible.
Elbows should be able to freely travel behind shoulders symmetrically. The distance elbows travel behind shoulders or range of motion is noted.
Elbows must be kept at shoulder height during attempt for consistent assessment protocol. A mirror may help monitor proper form and assist in a more accurate assessment. Note any pain or discomfort during movement. See Shoulder Transverse Adductor Inflexibility and Protracted Shoulder Girdle.
