全膝关节置换术对本体感觉的影响

目的：探讨全膝关节置换术后对患侧本体感觉的影响。方法：选取48例全膝关节置换术后3个月的患者（置换组）和50例同龄正常人（健康组）,以Biodex 3等速系统测试双膝关节主动复位的误差角度,以作为个体本体感觉能力优劣的评估指标。结果：置换组患者术侧膝关节主动复位误差角度显著大于健康组的左右膝（P〈0.05）。结论：全膝关节置换术后患者的个体本体感觉明显降低,因此其运动康复计划中应包含本体感觉的训练。

Effects of Total Knee Arthroplasty on Proprioceptive Function

Objective： To observe the influence of total knee arthroplasty（TKA） on proprioceptive function.Method： Forty-eight patients three months after TKA（TKA group） and 50 age-matched healthy people（healthy group） were selected.The proprioceptive function of all subjects was 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 TKA group had significantly worse active reposition sense than healthy group（P0.05）.Conclusion： The active position sense in patients with TKA is impaired.It was recommended that rehabilitation program for TKA should include the proprioceptive training,especially in restoring the active reposition sense.
