Abstract: BACKGROUD: The control of hip and ankle joint movement is important for patients with dynamic knee valgus (DKV), but few studies have used non-elastic taping (NET) to adjust alignment of the hip and ankle joints during overhead squat (OHS) simultaneously in patients with DKV. OBJECTIVE: We investigated changes in lower extremity joint kinematics and dynamic balance after the application of NET to the hip and ankle joints during OHS. METHODS: A total of 30 DKV patients participated in this study. We determined the kinematics of the hip, knee, and ankle joints, and scores on the lower quarter Y-balance test (YBT-LQ) during OHS under three conditions (non-taping, NET on hip and ankle, and sham taping). RESULTS: Hip internal rotation, knee valgus, and the ankle dorsiflexion angle were significantly lower with NET than with non- or sham taping. The hip flexion angle and scores on the YBT-LQ were significantly greater with NET than with non- or sham taping. CONCLUSIONS: The application of NET while performing a OHS is a useful method for correcting lower extremity alignment in patients with DKV, however, application of NET on the ankle should be considered.
