The etiology was feathering multi-factorial. Femur internal rotation was proved to contribute in patella lateral laterization position in patients with PFPS. Excessive hip adduction and internal rotation during various tasks were recognized in patients with PFPS and associated with the increased stress of patellofemoral joint. Therefore, hip movement control can be an important issue when making management decision. Hip stabilization brace was proved to be effective in pain reduction, decreasing hip internal rotation and improving posture stability. Kinesio taping has been applied in the upper extremity for movement correction. However, whether applying Kinesio taping is able to correct the movement patterns of the lower extremity during weight bearing activities remains unknown. Therefore, the purpose of this study was to investigate the immediate effects of hip corrective taping on hip and knee movements during lay-up jump and single-leg squat in basketball players with PFPS. Methods: 12 basketball players (10 males, 2 females) with PFPS and 14 healthy (10 males, 4 females) player were asked to perform lay-up jump and single-leg squat with and without corrective taping. Whole body kinematics and ground reaction forces were recorded using Vicon 3D motion analysis system (200Hz) and an AMTI force plate (1000Hz). The primary objectives of corrective taping in this study were to limit hip adduction and internal rotation and provide guidance of hip abduction and external rotation during tasks. Thus, kinesio tape was applied from 3 cm below medial tibia epicondyle to 3 cm above ipsilateral anterior superior iliac crest spirally with maximal tension. Results: The PFPS group showed greater knee external rotation than healthy players (10.23° v.s. 4.88°) but no significant differences in hip joint kinematic during lay-up jump. However, distance between center of mass and hip joint center in PFPS group was shorter than control group. In terms of taping effects, for lay-up jump task at initial contact, the angle of knee external rotation was significantly decreased after taping. (10.24° vs. 8.02°, p = 0.038). For single-leg squat task, hip internal rotation was significantly decreased (7.94° vs. 4.72°, p = 0.050). A trend of decreased hip adduction were also observed (11.45° vs. 10.16°, p = 0.059). Conclusions: Corrective taping applied in this study may have the effects of decreasing hip adduction and internal rotation in basketball players with PFPS during both static and dynamic tasks. Clinical Relevance: The results of current study provided evidence for corrective taping in basketball players with PFPS to limit hip movement patterns associated with increased patellofemoral joint stress. Clinically this taping method may be beneficial for the other populations with PFPS.
