Validity of manual muscle testing

Scott C Cuthbert and George J Goodheart Jr. The aim of this report is to provide an historical overview, literature review, description, synthesis and critique of the reliability and validity of manual muscle test (MMT) in the evaluation of the musculoskeletal and nervous systems. More than 100 studies related to MMT and the applied kinesiology … Continue reading Results: The ability of manual muscle testing to detect 15, 20, 25 and 30% between-side differences and deficits in knee extension force was described. Although the specificity of manual muscle testing was acceptable (mostly>80%), its sensitivity to differences between sides and to deficits relative to normal never exceeded 75%. Manual Muscle Testing . 16 muscle groups/ motions will be tested (not individual muscles). 14 of these are tested bilaterally. Grading will be based on the isometric "Break" test. It is essential that a grade of 3 be established before proceeding to application of resistance for grades above 3 or to alternate gravity minimized tests for Manual muscle testing by handheld dynamometry has been compared with MVIC for inter- and intrarater reliability by Visser et al. 34 Both techniques were acceptably reliable and correlated well for longitudinal evaluation of muscle strength in patients with On the reliability and validity of manual muscle testing: a literature They concluded that "The MMT employed by chiropractors, physical therapists, and neurologists was shown to be a clinically useful tool, but its ultimate scientific validation and application requires testing that employs sophisticated research models in the areas of neurophysiology, biomechanics, RCTs, and statistical analysis." The study, "On the Reliability and Validity of Manual Muscle Testing: A Literature Review," by Drs. Scott C. Cuthbert and George J. Goodheart, Jr. presents the results of more than 100 peer-reviewed studies related to the MMT and the applied kinesiology chiropractic technique (AKCT). It is used to evaluate weakness and can be effective in differentiating true weakness from imbalance or poor endurance. It may be referred to as motor testing, muscle strength grading, manual muscle testing, or any other synonyms. Muscle strength can be assessed by a number of methods-manually, functionally, or mechanically. [1] Validity of the Modified Manual Muscle Test [ Time Frame: Baseline- Baseline plus 4 hours ] The inter-rater reliability of the BMRC will be measured by the ICC. The ICC of the BMRC will be estimated and analysed as previously described for the primary analysis. The ICCs of the MMMT and the BMRC will be compared descriptively. Manual Muscle Testing (MMT) practiced by over a million practitioners worldwide. However, it's accuracy under varying levels of blindness has not yet been considered. This study will test this accuracy. Study Hypothesis: MMT can accurately distinguish congruent from incongruent statements. Results: The ability of manual muscle testing to detect 15, 20, 25 and 30% between-side differences and deficits in knee extension force was described.Although the specificity of manual muscle testing was acceptable (mostly>80%), its sensitivity to differences between sides and to deficits relative to normal never exceeded 75%. Manual muscle testing (MMT) and hand-held dynamometry (HHD) are commonly used in people with inflammatory myopathy (IM), but their clinimetric properties have not yet been sufficiently studied.
