Methods: A quantitative, non-intervention clinical exploratory study. Fifty participants were divided into two groups, Group A (40 symptomatics) and Group B (10 asymptomatics). Both groups were screened for vastus lateralis and vastus medialis trigger points. Subjective data was obtained from Group A only, using the Numerical Pain Rating Scale and the Patient Specific Functional Scale. Objective data was obtained from both groups using the algometer, Myofascial Diagnostic Scale, and the Cybex 700 Isokinetic Dynanometer. For descriptive analysis frequency tabulations, box and whisker plots were used to display distributions graphically. Comparisons of categorical and quantitative variables between independent groups were run using chi square and Mann-Whitney testing consecutively. Finally Spearman’s correlation, multivariate generalized linear modelling and repeated measures ANOVA were also used. All statistical analysis was completed at the 95% (p<0.05) level of confidence.95 penChiropracticLong distance runningMyofascial pain syndromes--Chiropractic treatmentKnee--Wounds and injuries--Chiropractic treatmentPatellofemoral jointThesishttps://doi.org/10.51415/10321/230
