Reliability and Validity of Manual Muscle Testing
Author Information
Author(s): Cuthbert Scott C, Goodheart George J Jr
Hypothesis
Is the MMT approach worthy of scientific merit?
Conclusion
Manual muscle testing (MMT) is a clinically useful tool for evaluating musculoskeletal and nervous system dysfunction, but requires further sophisticated research for validation.
Supporting Evidence
- More than 100 studies related to MMT were reviewed.
- Evidence for good reliability and validity in MMT for neuromusculoskeletal dysfunction was found.
- 12 randomized controlled trials showed MMT findings were not dependent on examiner bias.
Takeaway
This study looks at how well manual muscle testing works for checking muscle strength and health. It shows that MMT can be helpful, but more research is needed to prove it really works.
Methodology
The authors reviewed over 100 studies on manual muscle testing, assessing their quality and categorizing them by reliability and validity.
Potential Biases
Potential bias due to the subjective nature of muscle testing and variability in examiner experience.
Limitations
The review may not include all relevant studies and lacks critical ratings for internal and external validity.
Participant Demographics
The studies reviewed included various patient populations with musculoskeletal and neurological conditions.
