“…The four chosen exercises are used frequently in physical therapy clinics and have been investigated in previous studies with conflicting results [16,17,19,41]. All of the exercises tested produced relatively high VMO/VL ratios, however this study indicates that there is a statistically significant increase in the EMG activity of the VMO and VL during the SAQ exercises over the SLR, regardless of hip position.…”

“…Other researchers have hypothesized that there will be an increase in VMO activity with external rotation of the hip because of the VMO's muscular fibers originating from the adductor magnus muscle. Based on this thinking, when the hip is placed in an externally rotated position and flexed using the adductors, the VMO would be stimulated, therefore causing an increase in EMG activity [10,[17][18][19]. This study found, however, that there was no significant difference between VMO activation during lateral rotation or neutral positioning of the hip.…”

“…Despite PFPS being more prevalent in females [17,19,[36][37][38], several studies reviewed used exclusively male subjects [39,40]. In order to broaden the patient population that this study is applicable to, we chose to include both males and females.…”

Abstract:The purpose of this study was to compare four common rehabilitation exercises used in physical therapy clinics for activating the vastus medialis oblique (VMO) and vastus lateralis (VL). Thirty-four subjects, aged 22-28 years, without patellofemoral pain syndrome (PFPS) (18 females and 16 males) were recruited. Subjects performed four exercises-straight leg raise with neutral and externally rotated hip positions (SLRN, SLRER), and short arc quad with neutral and externally rotated hip positions (SAQN, SAQER). The integrated electromyographic (iEMG) activity of the VMO and VL and were recorded, with means of the VMO, VL and VMO/VL compared across exercises. No significant difference was found for the VMO/VL ratio across the four exercises (p=0.147). However, for the VMO and VL individually, a significant difference was found (p=0.0001), SAQER was significantly greater than SLRN and SLRER; SAQN was significantly greater than SLRN and SLRER.These findings suggest that exercises including short arc quad knee extensions are more effective for both the VMO and VL activation than those incorporating straight leg raises, and potentially more beneficial in the rehabilitation of patients with PFPS.
