Muscle testing is an important procedure to assess the function and strength of the individual muscles and group of muscles.
Manual muscle testing is a procedure where the function and strength of the muscles are studied based on the performance and movement under manual resistance and gravitational forces.
When a patient is tested to have “fair muscle strength and the muscles are at 50% normal condition”, it means that “there is Full range of motion with gravity”. It indicates that the muscle is capable of holding test position against gravity.
