Manual Muscle Testing (MMT) is a procedure to measure the function and strength of individual muscles and muscle groups. Hand-held myometry, using a device known as a dynamometer, is one method used for MMT. The dynamometer is held against the patient's limb by the examiner and the patient is asked to resist the force applied by the examiner. The dynamometer measures the force applied by the patient, providing a quantitative and objective assessment of strength of the particular muscle or muscle group. The effectiveness of a therapeutic intervention on muscle strength, as measured by hand-held myometry, can be assessed by comparing post-treatment to pre-treatment (baseline) measurements.
