Objectification of the Functional Myodiagnosis Muscle Test

Area of Science:

• Biomedical Engineering
• Sports Medicine
• Complementary Medicine

Background:

• Subjective muscle strength assessments lack objective verification.
• Functional Myodiagnosis muscle test (FMD-MT) is an accepted complementary medicine method.
• Reliability of manual muscle testing requires further scientific evidence.

Purpose of the Study:

• To objectively verify subjective FMD-MT assessments using measurable physical parameters.
• To evaluate the reliability and validity of the FMD-MT.
• To reinforce scientific evidence for this complementary medicine approach.

Main Methods:

• Crossover observational study with 24 healthy participants.
• FMD-MT of the rectus femoris muscle performed by three experienced practitioners.
• Measurements recorded via oscillogram, analyzing force-time integral, joint angle change, and additional force load.

Main Results:

• Significant differences found in force-time integral, joint angle change, and additional force load between strong and weak muscles (p<0.005).
• Examiners showed high accuracy (99.2-100%) in muscle strength classification.
• Excellent interrater reliability (ICC=0.984) and high oscillogram accuracy (81.7-86.7%) were observed.

Conclusions:

• FMD-MT objectively differentiates strong and weak muscles.
• Statistically significant differences in key parameters confirm FMD-MT's objectivity.
• The FMD-MT is a valid (99.6%), reliable, and reproducible diagnostic method.
