Abstract: A study examining the efficacy of patellar taping on the level of pain, isokinetic performance and muscle activities of vastus medialis obliquue (VMO) and vastus lateralis (VL) was performed. A total of fifteen subjects diagnosed with patellofemoral pain syndrome (PFPS) and presented with patellar malalignment and moderate intensity of pain were studied. The tests included level of pain during squatting at 30o of knee flexion, assessed by visual analogue scale (VAS), root mean square value (RMS) of surface electromyographic (SEMG) recordings of VMO and VL at 30o knee flexion with 20% of extra body weight loading, and isokinetic knee exercise between 40o flexion and full extension at 120o/s. These parameters were measured before and after taping. All subjects were examined by a physiotherapist to determine the degree of patellar malalignment before the study. The procedures of taping and tension of the tapes were standardized for all subjects. The data for analysis included the VAS scores, EMG(RMS) ratio of VMO:VL, isokinetic extension peak torque and isokinetic total work. Data were analyzed with paired t-tests and 帢 was set at 0.05. Results of this study showed that there was a decrease in VAS scores (p=0.000), EMG ratio of VMO:VL (p=0.058) and an increase in isokinetic peak torque (p=0.121) and total work (p=0.246) after patellar taping. These results demonstrated that taping could reduce pain but offered no preferential activation of VMO over VL in a semi-squat position. Moreover, there were signs that it could enhance performance of the knee in the isokinetic testing protocol.
