Efficacy of Electromyographic-Biofeedback Supplementation Training with Patellar Taping on Quadriceps Strengthening in Patellofemoral Pain Syndrome among Young Adult Male Athletes

研究概要

Sixty young adult male athletes with patellofemoral pain syndrome were randomized to receive 4 weeks of electromyographic-biofeedback-guided isometric strength training plus patella taping (n=30) or 4 weeks of isometric strength training with sham electromyographic-biofeedback guidance and sham taping (n=30). Outcomes of interest included pain on the visual analog scale (VAS), knee function on the Kujala Anterior Knee Pain Scale, and quadriceps muscle strength which was measured using a dynamometer. Outcomes were assessed at 2, 4 and 6 weeks (2 weeks post-intervention) follow up. VAS pain scores were significantly lower in the intervention group compared to the control group at all time-points (p<0.001 for all). Moreover, quadriceps strength was significantly greater in the intervention group compared the control group at 4 and 6 weeks follow up (p<0.001 for both). Lastly, knee function scores were significantly in favour of the intervention group at 6 weeks follow up only (p=0.0002).
