Intro to MMT and Tests:

Manual Muscle Testing (MMT)

Manual Muscle Testing (MMT)

Evaluation of strength based on the relationship between gravity and manual resistance in the available Range of Motion (ROM) for a joint.

Kendall Scale

A 0-10 scale used in one school of MMT to grade muscle strength.

Daniels & Worthingham Scale

A 0-5 scale used in another school of MMT to grade muscle strength.

Break Test

Applying manual resistance until the Physical Therapist overpowers the patient, initiating an eccentric contraction.

Make Test

Applying manual resistance while the patient moves through the ROM, focusing on concentric contraction against maximal resistance.

Grading Scale

System used to assess muscle strength, including categories like Zero, Trace, Poor, Fair, Good, and Normal.

Intratester Reliability

Refers to the consistency of MMT results when performed by the same trained PT.

Intertester Reliability

Refers to the consistency of MMT results when performed by different individuals, which can vary more widely.

Order of Operations

Steps to follow during MMT, including observing muscle bulk, positioning the patient and joint, checking AROM, giving clear instructions, demonstrating movements, and testing the uninvolved side.

Audience Consideration

Considering factors like age or cognitive abilities when conducting MMT, such as adapting instructions for children under 7 or dementia patients.
