This is a simple shoulder rotation flexibility test, using just a long solid object. A similar, though more complex flexibility test of the shoulder, which accounts for the shoulder width, is the Acuflex III Shoulder Rotation Test.

• purpose: To test the flexibility of the shoulder joint, which is important for injury prevention and in particular is important in swimming, racket sports and throwing sports.
• equipment required: stick or towel, ruler or tape measure.
• procedure: Start by holding a towel or a stick in front of the body with both hands wide apart and palms facing downwards. Lift the stick over the head to behind the back, maintaining the hand grip on the object. Repeat the test, moving hands closer together each time until the movement cannot be completed. Alternatively, if your hands can slide along the stick or ruler, start with the hands close together, and as you swing the object over your head, slowly slide the hands apart just enough to enable it to go over your head and behind you. Repeat a few times.

• scoring: measure the minimum distance between hands.
• disadvantages: Variations in arm length and shoulder width can make comparisons between individuals misleading.
