前交叉韧带重建术后髋、膝、踝关节周围肌群在不同角速度下的等速肌力特征研究
Isokinetic muscle strength characteristics of hip,knee,and ankle muscles at different angular velocities following anterior cruciate ligament reconstruction
摘要
Abstract
Objective To evaluate isokinetic muscle strength of the hip,knee,and ankle musculature in patients following anterior cruciate ligament reconstruction(ACLR),and to analyze muscle strength imbalances across different joints and angular velocities,thereby providing evidence for optimizing postoperative rehabilitation strategies.Methods An isokinetic dynamometer was used to assess muscle strength in 40 patients after ACLR and 20 healthy controls.Isokinet-ic testing of muscle groups surrounding the hip,knee,and ankle joints was performed at different angular velocities.Key parameters,including relative peak torque(RPT)and muscle strength ratios,were recorded.Differences between ACLR patients and healthy controls,as well as between limbs,were analyzed.Results At angular velocities of 60°/s and 120°/s,significant differences were observed between the ACLR group and the control group in hip abductor and adductor RPT values and abductor/adductor ratios(P＜0.05).For the knee joint,significant differences were found in extensor and flexor RPT values as well as flexor/extensor ratios between the two groups(P＜0.05).Additionally,significant differences were identified in ankle invertor,evert or,plantarflexor,and dorsiflexor RPT values between groups(P＜0.05).Conclusion Patients following ACLR exhibit significant reductions and imbalances in isokinetic muscle strength of the hip,knee,and ankle musculature.These alterations vary across joints and angular velocities,indicating joint-spe-cific and velocity-dependent characteristics.Individualized rehabilitation programs tailored to joint-specific muscle strength profiles are essential to promote optimal recovery of muscle strength and functional performance after ACLR.关键词
