![]() Accordingly, this study’s aim was to investigate the influence of KT on trunk, hip and knee motions during a single-leg drop landing (SLDL), SLVDJ, double leg vertical drop jump (DLVDJ), and double leg forward jump (DLFJ) tasks. ![]() Investigating different landing tasks can enhance our understanding of the influence of KT on motion and injury risk. Using methods such as KT may help correct dynamic malalignment patterns, and reduce knee injury risk. Īccording to the author's knowledge, no study has tried to examine the sum of knee valgus and lateral trunk lean, lateral trunk lean, knee abduction, hip and knee flexion, and asymmetry of landing tasks after KT application. Also, through tactile input, KT has been able to stimulate cutaneous mechanoreceptors and alter motoneurons. Moreover, KT is known for improving function, stability, proprioception, and force production of the muscle. KT has several positive effects: improving lymphatic flow by increasing interstitial space, supporting muscles and joints, and correcting articular malalignment and function. KT is an elastic therapeutic tape used to prevent and treat sports injuries and various musculoskeletal conditions. While it is accepted that dynamic trunk, hip, and knee alignment influence one’s risk for ACL injury, it is largely unknown if kinesio taping (KT) may improve high-risk kinematics. Reduced asymmetry, specifically in regards to knee flexion, knee abduction, and hip flexion, can prevent lower extremity injury. In addition to intra-limb kinematics, inter-limb asymmetries are also shown to increase the occurrence of sport-related injuries. Greater KV allows the ground reaction force (GRF) to exert even greater frontal plane torque upon the knee joint. ![]() Increased lateral trunk lean causes the ground reaction vector to pass lateral to the knee joint, thereby creating an external knee abduction moment. A combination of increased two-dimensional (2D) measured KV and ipsilateral trunk lean was associated with increased external peak knee abduction moment during a single leg vertical drop jump (SLVDJ). In the frontal plane, greater KV displacement is a primary predictor of non-contact ACL injury risk. In the sagittal plane, the trunk and lower extremity work in a coupled fashion to attenuate landing forces, such that greater motion at one joint is typically accompanied by corresponding motion at adjacent joints, allowing for improved force absorption. Characterized by an erect landing posture and less sagittal plane trunk displacement, stiff landings result in greater ground reaction forces, external knee abduction and flexion moments, and smaller external hip flexion moments. Specifically, dynamic malalignment patterns comprised of greater ipsilateral trunk lean, hip adduction, hip internal rotation, knee valgus (KV) and tibial internal or external rotation, in addition to less hip and knee flexion, have been associated with greater knee joint loading and subsequently higher non-contact ACL injury risk during landing tasks. Poor sagittal and frontal plane movement patterns are believed to increase knee injury risk in athletes. ![]() In order to assess ACL injury risk and develop potential preventive strategies, researchers have typically measured biomechanical characteristics during various landing tasks. ![]() Level of evidenceĪnterior cruciate ligament (ACL) injuries frequently occur in non-contact situations such as landing. Therefore, KT application may marginally improve high-risk landing kinematics in competitive male athletes. The research findings suggest that KT after 72-h application may improve knee abduction and sum of knee valgus and lateral trunk lean during SLDL, knee flexion during SLDL and SLVDJ in individuals displaying risky single-leg kinematics. The KT application resulted in more knee flexion and abduction, sum of knee valgus and lateral trunk lean as compared with the non-KT condition during SLDL (P 0.05). The sum of knee valgus and lateral trunk lean, symmetry index (SI), and peak angles of lateral trunk lean, hip flexion, knee abduction and flexion were assessed for all participants during single-leg drop landing (SLDL), single-leg vertical drop jump (SLVDJ), vertical drop jump (DLVDJ), and double leg forward jump (DLFJ), at baseline and seventy-two hours following KT application. Twenty-nine competitive male athletes participated in this study. The purpose of the study was to investigate the influence of a 72-h KT application on trunk and lower extremity kinematics during different landing tasks. ![]()
