What does the back scratch test measure?

The back scratch test is specifically designed to measure shoulder range of motion, particularly the flexibility of the shoulder joint. During this test, an individual typically reaches one hand over the shoulder and the other hand behind the back, attempting to touch or grasp their fingers together. The distance between the fingers or whether they can touch indicates the range of motion in the shoulder girdle, assessing the flexibility of the muscles and connective tissues involved.

This test is particularly useful because shoulder flexibility is an essential component of overall functional fitness, affecting other movements in daily life and various sports activities. Improved shoulder range of motion contributes to better performance and a reduced risk of injury during upper body activities.

The other options, while they may be associated with flexibility or strength assessments, do not pertain to the back scratch test. Lower back strength is typically measured using different strength tests, hamstring flexibility is often assessed with tests like the sit-and-reach, and overall body flexibility encompasses a broader range of movements beyond the specific shoulder motion evaluated in the back scratch test.
