Abstract
Context: Anterior knee pain (AKP) is a symptom of poor biomechanics and strength deficits. Common hip rehabilitation programs perform only static, but dynamic exercises are more functional based. Objective: The purpose of the study was to determine if static or dynamic hip exercise increased knee stability and functional mobility while decreasing AKP in dancers. Design: Randomized factorial design. Setting: Controlled laboratory setting. Subjects: Twelve college-aged dancers (21.75±1.06yrs) voluntarily participated. Six of the 12 subjects perceived to have AKP. Interventions: Subjects reported to the laboratory twice (pre- and post-hip rehabilitation exercises) to measure their hip stability and functionality. An 8-week of static or dynamic hip rehabilitation exercises was randomly assigned in each subject. Measurements: Stability of the knee/hip was measured through the Y-Balance System and the BESS tests. Functional mobility was measured by the single and double leg squat analysis. A visual analogue scale was conducted to show perceived knee pain. Results: Improvements were observed from pretest to posttest for the Y-Balance System in anterior (F1,8=10.23, P=0.012), posteromedial (F1,8=5.51, P=0.047), and posterolateral (F1,8=16.33, P=0.004) directions, knee valgus/varus (F1,8 =6.14, P=0.02) for the single leg squat, and overall scores (F1.8=15.75, P=0.004) for the double leg squat. Interactions were found between pain x treatment (F1,8=6.37, P=0.036) and pain x testing (F1,8= 121.94, P<0.001). Conclusions: Performing hip rehabilitation exercises seemed to improve knee and hip stability and functional mobility. It was not determined if static or dynamic exercises had a higher increase than the other. Dynamic hip exercises decreased AKP more compared to static.
