Background Muscle imbalance between the vastus lateralis (VL) and vastus medialis (VM) can lead to patellar maltracking, particularly lateral displacement of the patella, which is a common cause of patellofemoral pain syndrome (PFPS). Non-elastic taping, such as the McConnell taping method, is frequently applied in clinical practice to inhibit overactive muscles and improve joint alignment. However, the influence of taping direction—whether applied across or along muscle fibers—on muscle inhibition remains unclear, with inconsistent findings reported in previous research. Objectives This study aimed to investigate the inhibitory effect of non-elastic taping on the VL based on the direction of tape application and to determine the more effective taping approach during isometric knee extension in healthy adults. Methods Twenty healthy adults (15 males, 5 females) participated. Each performed seated isometric knee extension for 5 seconds before and after applying inhibition taping either the transverse or longitudinal direction of the VL muscle fibers. Results Transverse and longitudinal taping techniques are significantly reduced VL activity (p < 0.05). Conclusions Transverse and longitudinal taping showed inhibition of VL activity, suggesting its usefulness in clinical interventions for muscle overactivation and related knee joint disorders.
