FREE MMT Limitations and Considerations Questions and Answers
What is one of the main limitations of Manual Muscle Testing?
MMT relies on the examiner’s ability to apply consistent resistance and grade accurately, which can lead to variability between testers.
How can patient factors, such as pain, affect MMT results?
Pain during testing may prevent patients from exerting full effort, leading to underestimation of their actual muscle strength.
Why might MMT be less accurate in young children?
Young children might have difficulty following instructions or may not consistently participate in the test, affecting reliability.
In which situation would an alternative to MMT, such as a dynamometer, be more appropriate?
A dynamometer provides precise and objective data on muscle strength, which is useful for tracking progress or comparing results across time or populations.
Why is inter-rater variability a concern in MMT?
Inter-rater variability occurs when different testers perform MMT differently, leading to inconsistent results. This is a key limitation that affects the reliability of MMT across multiple clinicians.
