- Abstract
- Reciprocal inhibition (RI) is a neurological phenomenon documented to be of importance in mediating the inhibition of antagonist motor neurons during movement. Within the field of osteopathic medicine, the theory of RI has been used as one explanation for the effectiveness of muscle energy techniques (MET). MethodsThis paper examined for the presence of RI in 11 healthy, asymptomatic male subjects (n=11), aged between 18-40 years in a randomised crossover study. Surface Electromyography (sEMG) data was monitored of both the agonist and antagonist muscle groups, the quadriceps and hamstrings respectively, during three separate visits. Measuring electrical activity during 100%, 20% and 0% of the patient's perceived maximal voluntary contraction (MVC) force output. Range of motion (ROM) data of knee and hip flexion, was also observed as a method of establishing any increased ROM as a result of each visit. The study was also able to examine the accuracy of the subject's supposed 20% MVC, this is of relevance as 20% MVC is the suggested force recommended to maximise the effectiveness of MET. ResultsA two way analysis of variance (ANOVA) with statistical significance set at (p<0.005) was used in analysis of quadriceps and hamstrings sEMG data and hip and knee flexion range of motion (ROM). A t-test was used to analyse differences between participant 20% and 100% MVC, and the calculation (=CellA/CellB*100) was used to determine the accuracy of each participants subjective 20% MVC. Results showed no presence of sEMG signal depression or evidence of RI during isometric quadriceps contraction. No statistical significance was observed concerning changes in hip or knee flexion ROM. Only one participant accurately averaged a percentage of submaximal contraction within 20-30% MVC. ConclusionThis study suggests that the effect of MET may not be due entirely to RI and that if the effectiveness of METs is maximised at 20-30% MVC, then the method for determining the accuracy of a patient’s subjective measurement in a clinic scenario should be revised.
