Flexibility is the capacity of a joint to move through its full range of motion. Flexibility tests are used to measure the range of motion in a joint and are often part of the physical examination. Although sometimes a single flexibility test is used in a test battery to represent a flexibility score, there is no single test that gives you a score for overall flexibility – each test is specific to a particular movement or joints.
Flexibility tests may be used to help determine whether you have a muscle imbalance or arthritis in a joint or to help determine the progression of a condition such as shoulder impingement or a sprain. There are several different kinds of flexibility tests, geared to specific joints and muscles. Your doctor may ask you to reach or bend or to move the affected extremity in a certain way. No preparation is required, and normally these tests are not painful.
