Introduction: Kinesiology is a diagnostic, therapeutic
complementary therapy utilising subtle change in manual
muscle testing results to evaluate the body’s energetic
balance and select healing modalities. Anecdotal evidence
suggests kinesiology is helpful, therefore we
wished to critically review the literature. Aims: (1) To ascertain
if diagnostic accuracy including inter-examiner
reliability has been established. (2) To review whether
there is evidence for its therapeutic effectiveness. (3) To
critically assess the quality of relevant studies. Methods:
Electronic databases were searched. Diagnostic accuracy
studies were analysed and scored for methodological
quality and quality of reporting using the quality assessment
tool for studies of diagnostic accuracy included in
systematic reviews (QUADAS) and the Standards for Reporting
of Diagnostic Studies (STARD). Clinical studies
were analysed for methodological quality using the
JADAD scale and for quality of reporting using the Consolidated
Standards of Reporting Trials (CONSORT). Results:
22 original relevant studies were identified. Their
methodology was poor. Items reported on QUADAS
scored 1-11 out of a possible 14, STARD scores were between
6-13 out of 25, JADAD scores were all 0 out of 5
and CONSORT 4-6 out of 22. Consequently, we were unable
to answer any of our research questions. Conclusion:
There is insufficient evidence for diagnostic accuracy
within kinesiology, the validity of muscle response
and the effectiveness of kinesiology for any condition.
The standards of reporting were low. We recommend a
pragmatic study of the effectiveness of kinesiology as
the most appropriate initial step to determine whether
kinesiology has any clinical value.
