| Abstract | Anterior cruciate ligament reconstruction (ACLR) is essentialfor athletes recovering from ACL injuries, yet many face challenges in regaining pre-injury performance due to persistent muscle imbalances and altered knee biomechanics. Objective:Toexaminethe effects of incorporating Single-Leg Hamstring Bridge (SLHB) exercises into standard ACLR rehabilitation protocols, focusing on hamstring strength and knee joint kinematics during running.Methodology:Eight male athletes (mean age 23.4±3.1years) who had undergone ACLR with hamstring tendon autografts were randomly assigned to a control group (standard rehabilitation only) or an intervention group (standard rehabilitation+SLHB) for six weeks. Hamstring strength was measured via isokinetic peak torque at 60°/sec, and knee kinematics, such as knee angle at foot strike, were recorded during treadmill running at 3.35m/s.Results:The IG shows significant improvement in knee flexion peak torque of the uninvolved leg(p = 0.016)post-intervention, and knee angle at the foot strike of the uninvolved leg(p = 0.037) compared to the CG.Conclusion:Adding SLHB to standard ACLR rehabilitation significantly enhanced hamstring strength in the uninvolved limb and improved knee positioning at foot strike, suggesting better dynamic knee stability and lower-limb function. However, because strength gains were confined to the uninvolved leg, conclusions about benefits for the operated limb remain tentative. SLHB may improve gait mechanics during ACLR rehabilitation;however,further studies with larger samples and longer follow-up are needed to confirm its effects on the surgical limb and long-term return-to-sport outcomes |
