Visible or palpable contraction with no motion a 1 2. One arm cradles test limb around thigh with hand supporting underside of knee. Manual muscle testing procedures key to muscle grading. Grading follows the medical research council mrc system table 1. It is not necessary, therefore, to use a hand to manually stabilize the contralateral limb. Manual muscle testing mmt is a method diagnostic evaluation used by physical therapists, chiropractors, physiological researchers and others concerned with establishing effective treatment and tracking progress throughout a specific regimen.
Pillows are placed under the knee to flex the hip to 90 degrees. This is one of the cardinal principles of manual muscle testing. Some muscle groups are listed here with antigravity testing, but for a weaker patient, these would be tested in a sidelying or supine position, per the table below. Generally, for bilateral muscle testing, each muscle group is first tested on the right and then the left, prior to proceeding to the next muscle group in the list. Sidelying with test limb superior to the supporting limb. Applied kinesiologists use submaximal manual break tests and a binary grading scale to test shortterm changes in muscle function in response to challenges. A patient should be able to stand on one leg keeping the pelvis level with a muscle grade of 4 or 5. It is essential that a grade of 3 be established before proceeding to application of resistance for grades above 3. See available hand held dynamometers for sale mmt is such an important part of a physical therapy examination and grading strength an. Mmt is a procedure for the evaluation of strength of individual muscle or muscles group, based upon the effective performance of a movement in relation to the forces of gravity or manual resistance through the available rom. On the reliability and validity of manual muscle testing. The most commonly accepted method of evaluating muscle strength is the oxford scale aka medical research council manual muscle testing scale.
In a bedridden patient, grades 5, 4, and 3 are tested with the bed in the chair position, or the head of the bed elevated as far as possible. The examiner assures that the foot is lifted off the bed when asking the patient to raise the knee off the bed. Through full range actively against strong resistance. The evolution of current methods of manual muscle testing can be traced back to the early 1900s, when gravity tests were used to assess spinal nerve damage.
Introduction to the topic mmt is the most vital part of motor assessment performa in medical examination. Figure 1 illustrates an algorithm for the mrc muscle strength scoring. In a survey by the national board of chiropractic examiners in 2000. This table provides a preferred order to the testing of muscle groups for manual muscle testing.
