Abstract
ABSTRACT AIMS & OBJECTIVES The aim of this study is to evaluate and compare the effects of Short-Arc and Isometric Quadriceps exercises on Quadriceps strength and health related quality of life among Anterior Knee pain patients by using EMG biofeedback. METHODOLOGY Total 80 participants were recruited and randomly distributed in two groups; A and B. Individuals in group A performed isometric quadriceps exercise while group B participants performed short-arc exercise for 1st, 6th and 8th week along with a home exercise programme. Pre and post treatment assessment was performed using EMG Biofeedback, VAS, and KUJALA scoring questionnaire. Statistically, data was analysed using SPSS version 20. RESULTS After 8 weeks, EMG Biofeedback revealed the higher effectiveness short-arc exercises with value 88.20mv ± 6.64 comparing isometric quadriceps exercises. Moreover, Wilcoxon rank test revealed statistically significant improvement in VAS score with p-value <0.05. Furthermore, KUJALA score also advocated the effectiveness of short-arc exercises with statistically significant values (p-value < 0.05). CONCLUSION The study concluded the effectiveness of Short-arc quadriceps exercises comparing to static-quadriceps exercises in improving muscles strength, pain and health related quality of life after 8 weeks of intervention.
