영문 초록

Patellofemoral pain syndrome (PFPS) is often attributed to malalignment and maltracking of patella within the patellofemoral joint. Most exercise for PFPS has focused on selectively strengthening the vastus medialis oblique muscle (VMO). This study was designed to identify the effect of medial, lateral wedge and difference of Quadriceps angle (Q-angle) on vastus medialis oblique/vastus lateralis muscle CVL) activity ratios. The subjects were twenty young adult males who had not experienced any knee injury. They were asked to per form isometric contraction exercises in three postures using medial and lateral wedge. The EMG activity of the VL and VMO were recorded in three postures by surface electrodes and normalized by %MVC values derived from seated, isometric knee extensions. The normalized EMG activity levels (%MVC) of the VL and VMO for the three postures of the lower extremities were compared using 2-way repeated measures ANOVA with 1 between-subject factor (group), and 1 within-subject factor (wedge). Results of repeated measures of ANOVA’s revealed that the medial wedge isometric contraction exercise produced significantly greater EMG activity of VMO/VL, ratios in Group Ⅰ (Q-angle 18° or less) (p＜.05). But, the medial wedge isometric contraction exercise was no significant difference of VMO/VL ratios in Group Ⅱ (Q-angle 19° or more) (p＞.05). These results have important implications for selective VMO muscle strengthening exercises in PFPS patients.
