等速肌力训练结合半导体激光对急性期膝关节骨性关节炎康复效果研究

Rehabilitation effect of isokinetic muscle training combined with semiconductor laser on acute knee osteoarthritis

目的探讨应用等速肌力训练联合半导体激光照射对急性期膝关节骨性关节炎(KOA)的康复治疗效果.方法将符合入组标准的98例KOA患者随机分成4组,所有受试者均给予常规康复治疗与护理,在此基础上,实验组1给予半导体激光治疗,实验组2给予等速肌力训练,实验组3给予激光照射联合等速肌力训练.患者分别于治疗前和治疗4周后进行骨关节炎指数评定和患侧膝关节周围屈伸肌群指标评定,包括峰力矩、峰功、平均功率、平均功、屈伸肌的峰力矩比值,并比较其差异.结果 4种治疗方案均可显著性缓解急性期KOA患者病情,改善患侧膝关节周围肌肉状况.等速肌力训练对KOA患者膝关节功能的改善优于激光照射治疗.等速肌力训练联合激光照射对KOA患者膝关节疼痛、僵硬、功能障碍、及屈伸肌群肌力等状况的改善最为显著.结论等速肌力训练联合半导体激光照射对缓解急性期KOA患者疼痛、僵硬、功能障碍,提高患侧下肢肌力有着显著疗效,同时较好的解决了缓解症状和增强功能问题,优于单纯药物治疗或单纯理疗、运动锻炼方案.

Objective To evaluate the effect of isokinetic muscle training combined with semiconductor laser on acute knee osteoarthritis (KOA).Methods Ninety-eight KOA patients were randomly divided into 4 groups.All patients were treated with conventional rehabilitation treatment and nursing.Based on that treatment,the group 1 received semiconductor laser irradiation,the group 2 received isokinetic muscle training,and the group 3 received laser irradiation combined with isokinetic muscle training.All patients were assessed with WOMAC osteoarthritis rating scale and affected knee extensor and flexor muscles strength measurement including peak torque,peak work,average power,average work and flex/extend before and 4 weeks after the treatment.Results All of the four treatments can significantly alleviate the condition of acute KOA patients and improve the muscle condition around the ipsilateral knee joint.The isokinetic muscle training improves the knee function of KOA patients better than the laser irradiation treatment.Isokinetic strength training combined with laser irradiation can get the most significant improvement of knee joint pain,stiffness,dysfunction,muscle strength of flexors and extensors in KOA patients.Conclusions The combination of isokinetic muscle training and semiconductor laser irradiation has a significant effect on relieving pain,reducing the stiffness,improving the function of knee of the patients with KOA in the acute phase and improving the muscle strength of the affected lower extremities.That methad is superior to drug therapy,physical therapy,or exercise alone,and is better to solve the problem of relieving symptoms and enhancing function simultaneously.
