Tests For Length Of Shoulder Rotators

MEDIAL ROTATORS

LATERAL ROTATORS

Equipment: Firm table; no soft padding.

Starting Position: Supine, with the low back flat on the table, arm at shoulder level (90° abduction), elbow at the edge of the table and flexed to 90° and forearm perpendicular to the table.

lest for Length of Medial Rotators: Lateral rotation of the shoulder, bringing the forearms down toward table level, parallel with the head. (Do not allow the back to arch up from the table.)

Normal Range of Motion: 90° (forearm flat on the table while maintaining the low back flat on the table).

Note: If the test for tightness of the teres major and latissimus dorsi (see p. 309) shows limitation, but external rotation (as above) shows normal range, then tighmess is in the latissimus dorsi but not in the teres major.

Equipment: Firm table; no soft padding.

Starting Position: Supine, with the low back flat on the table, arm at shoulder level (90° abduction), elbow at the edge of the table and flexed to 90° and forearm perpendicular to the table.

Test for Length of Lateral Rotators: Medial rotation of the shoulder, bringing the forearms downward toward table, while the examiner holds the shoulder down to prevent substitution by the shoulder girdle. (Do not allow forward thrust of the shoulder girdle.)

Normal Range of Motion: 70°

with the table.)

(forearm at a 20° angle

To test for excess.ve range of motion in lateral rotation, it is necessary to have the elbow slightly beyond the edge of the table to allow the forearm to drop below table level. Excessive lateral rotation is frequently found.

This subject demonstrated marked limitation of «na-dial rotation and excessive lateral rotation-an imbalance often seen in baseball players,
