Link to Instrument Instrument Details. Acronym MMT. Assessment Type Performance Measure.
Musculoskeletal Conditions. Spinal Injuries. Pediatric Disorders. Non-Specific Patient Population. Number of Items Determined by the number of muscles being tested.
Less than 1 minutes. Required Training No Training. Infant 0 - 2 years. Preschool Children 2 - 5 years. Child 6 - 12 years. Adolescent 13 - 17 years. Adult 18 - 64 years. Considerations MMT may not be sufficiently sensitive to measure strength in good and normal range. Schwartz et al, Herbison et al and Schwartz et al found significant differences in strength change over time using myometry that were not detected with manual muscle testing with strength grades greater than 3.
In this grade, a patient is able to perform complete range of motion with the addition of gravity and minimal resistance. In this grade, the patient can complete the complete range of motion against gravity, however, will be unable to perform the test with any added pressure.
There are two sides to this grade. Grade 2- Poor - : With Grade 2-, patients can only move partially in a horizontal plane. The distinction with this grade is that movement can only be performed partially and only when both gravity and resistance has been eliminated. Grade 1 Trace : Grade 1 is the last of the manual muscle grades and indicates that there is no visible movement on the tested body part.
In muscle testing, with this grade, patients are unable to move the tested body part at all regardless of the lack of resistance or gravity. Modern methods for doing physiological testing have adopted standard accepted procedures and grading systems that allow physicians to understand and communicate muscle testing findings. Muscle testing can be performed using manual strength testing, functional tests, and dynamometry.
Manual muscle strength testing is one of the most commonly used form of muscle testing by practitioners. With MMT, the patient is instructed to hold the corresponding limb or appropriate body part to be tested at a specific point in its available range of motion, working against gravity or while the practitioner provides opposing manual resistance to determine the grade to assign the muscle.
MMT is such an important part of a physical therapy examination and grading strength an invaluable skill that when performed appropriately can provide the rehabilitation practitioner necessary information which can assist him or her in planning appropriate interventions, modifications, or treatments. There are specific protocols to use when doing MMT to ensure accurate results. These protocols are necessary to get the most accurate results with manual muscle testing.
Conversely, there are some things to avoid which can negatively impact results. Here are some of the other things that you should consider when performing manual muscle testing:. In , Florence Kendall and two other authors published a guide to performing muscle testing: Muscles: Testing and Function. Detailed below, published by the National Institute of Health is an adaptation from the discussion of muscle testing procedures found in that book, which established a widely accepted grading chart that can be used by physicians to assess patients.
Grade 5 Normal. Grade 4 Good. Grade 1 Trace. Grade 5 Normal : This grade means the patient is able to complete the full range of motion movement against gravity while the practitioner applies maximum resistance. Grade 4 Good : This grade means the patient is able to complete the full range of motion movement against gravity while the practitioner applies moderate resistance.
