What is the primary purpose of manual muscle testing in physical therapy?

• A. To diagnose ligament injuries
• B. To assess cardiopulmonary endurance
• C. To quantify strength and monitor change over time
• D. To measure range of motion

Answer: (C)

Manual muscle testing is used to quantify how much force a muscle can generate against resistance and to track changes in that strength over the course of rehabilitation. By applying a controlled amount of resistance and grading the response, clinicians can measure gains or losses in muscle strength, guide progression of exercises, and set measurable goals. This differs from tests for ligament injuries (which assess stability), cardiopulmonary endurance (which measures aerobic capacity), and range of motion (which assesses how far joints can move).
