Recent studies have suggested that retropatellar pain can be minimized by focusing treatment on correct tracking of the patella. The purpose of this study was to examine the effects of patellar taping on quadriceps muscle function during concentric, eccentric, and isometric contractions. Fourteen qualifying subjects ranging in age from 19 to 29 years (X=23) underwent a series of closed chain exercises while electromyograph (EMG) recordings were made from the vastus medialis obliquus (VMO) and vastus lateralis (VL) muscles. A two-way analysis of variance for repeated measures compared VMO:VL ratios for concentric, eccentric and isometric exercises. There were no significant differences (P<..05) in EMG activity between the conditions of before and after patellar taping. This study showed that patellar taping did not result in an increase in VMO muscle activity in subjects with patellofemoral symptoms.
