全膝关节置换术前本体感觉训练对术后的影响

Influence of Preoperative Proprioceptive Training for Patients with Total Knee Arthroplasty

目的:探讨全膝关节置换术前本体感觉训练对术后功能恢复的影响。方法:选取48例严重膝关节骨关节炎且拟行全膝关节置换术的患者,随机分为2组。训练组26例在行全膝关节置换术前6周进行本体感觉训练,包括膝屈曲位、双单腿、睁闭眼等的平板训练,固定自行车练习等。对照组22例未进行本体感觉训练。2组分别在行全膝关节置换术前后6周进行膝关节本体感觉测试(即膝关节主动复位误差角度值);术后6周进行膝关节功能评分(Hospital for Special Surgery,HSS);以Biodex 3等速系统测量2组患者双膝关节主动复位误差角度,以作为个体本体感觉能力优劣的代表。结果:术后6周训练组患膝关节主动复位误差角度值明显小于术前及对照组(P<0.05)。HSS项目中的疼痛、行走功能、肌力及稳定性评分,训练组均明显高于对照组(P<0.05)。结论:全膝关节置换术前进行本体感觉训练,可以提高患者术后本体感觉及肢体功能。

Objective： To observe whether proprioceptive training can influence postoperative function in patients undergoing total knee arthroplasty（TKA）.Methods： Forty-eight subjects with severe osteoarthritis of the knee scheduled for TKA were randomly divided into control group（CG） and training group（TG）.Training group was given preoperative proprioceptive training.All patients with TKA were assessed with HSS and proprioceptive function before and six weeks after operation.The proprioceptive functions of all subjects were measured by a repositioning test on the Biodex Ⅲ dynamometer.The Bioedx Ⅲ isokinetic dynamometer was used to assess knee proprioceptive function： active position sense.Results： The results showed the training group had significant improvements in Hospital for Special Surgery（HSS）（P0.05） and active reposition sense（P0.05） compared to control group.Conclusion： It was concluded that preoperative proprioceptive training on patients receiving TKA can effectively improve the functions of knee and proprioception.
