Effect of protective taping on knee eversion angle and jump height during single-leg vertical jumps in patients with anterior cruciate ligament reconstruction.

[Purpose] Taping is often performed to prevent injury and injury recurrence. However, it is unclear how taping affects landing and jumping kinematics in patients undergoing anterior cruciate ligament reconstruction. Therefore, this study aimed to determine the kinematic effects caused by taping during single-leg vertical jumps in patients with anterior cruciate ligament reconstruction. [Participants and Methods] Ten young patients who underwent anterior cruciate ligament reconstruction were included. The maximum knee joint flexion angle, peak value of the vertical component of the floor reaction force, maximum knee joint eversion angle, and jumping height during a single-leg vertical jump were measured using a three-dimensional motion analyzer and compared among the following three groups: without taping, with protective taping using elastic tape, and with protective taping using non-elastic tape. [Results] There were no significant differences in the peak value of the vertical component of the floor reaction force or the maximum knee joint flexion angle among the three groups. The maximum knee joint eversion angle and jumping height were significantly lower in the elastic tape and non-elastic tape groups than in the non-taping group. [Conclusion] Anterior cruciate ligament taping does not affect the magnitude of the impact on the body and can decrease knee joint eversion. However, jumping height was lower in the two taping groups than in the no-taping group. There were no significant differences in the items studied between the two taping groups.
