![]() This information is important in training accurate muscle testers and in evaluating the reliability and validity of other AK procedures based on muscle responses to various stimuli and challenges.Īctive or “make” tests are similar to maximum isometric voluntary contraction tests-the subject presses against a fixed dynamometer, a strap with a force transducer is used, or the examiner acts as a fixed point. 1,3 The range of parameters that yield similar results on this binary evaluation is not currently known. Applied kinesiology (AK) authors suggest that manual muscle testing (MMT) measures a complex proprioceptive response to changing pressure, rather than strength of the muscle itself. If the muscle weakens during the procedure, the muscle is rated as “inhibited” or “weak” (grade 4 or less). If the subject can maintain the position against gradually increasing pressure, it is graded as “facilitated” or “strong” (grade 5). 1 Muscles are tested according to similar methods described by Kendall et al 2 from a contracted position with pressure toward lengthening. ![]() Applied kinesiologists test muscles before and after challenges and treatments, and may make clinical judgments based on immediate changes in muscle tests. ![]()
