What is Muscle Strength Evaluation by Manual Muscle Testing (MMT)?

Manual muscle testing is an examination technique standardized by Daniels and Worthingham, in which the strength of a muscle or muscle group is evaluated manually by a physiatrist.

Evaluation is graded between 0 (no contraction) and 5 (normal strength). Grade 3 (full motion against gravity) is a key point; below this it is evaluated in a gravity-eliminated position, and above it against gravity and against resistance.

MMT is used in the diagnosis, treatment planning and follow-up of rehabilitation effectiveness in neurological and musculoskeletal diseases. It can be supported by instrumental measurements such as a dynamometer.

Symptoms

Muscle weakness
Hemiplegia and hemiparesis
Neurological deficit
Peripheral nerve injury
Myopathy
Muscle atrophy
Gait disturbance

Risk Factors

  • In neurological disease follow-up
  • At the start of a rehabilitation program
  • In periodic rehabilitation follow-ups
  • In preoperative evaluation
