外踝扭伤后本体感觉的恢复

Recovery of proprioception after lateral ankle sprain

目的观察外踝扭伤常规康复后,患侧踝关节本体感觉随时间的恢复情况。方法2020年6月至2022年6月,昆山市康复医院外踝扭伤患者18例,均行常规康复训练12周。分别于治疗前、治疗4周、治疗8周和治疗12周时,采用等速肌力测试系统评估双侧踝关节主动位置觉和被动位置觉。结果治疗后,患侧踝关节主动位置呈现差逐渐降低(F=22.533,P<0.001),但均显著高于健侧同时间点(t>4.419,P<0.001);患侧踝关节被动位置呈现差无显著变化(F=1.175,P>0.05),与健侧同时间点无显著性差异(|t|<0.646,P>0.05)。结论外踝扭伤后患侧踝关节本体感觉受损,康复训练后逐渐恢复,但训练3个月后仍未恢复到健侧水平。被动位置觉作为评价本体感觉的指标有待进一步研究。

Objective To observe the recovery of proprioception of the affected ankle over time after lateral ankle sprain accepting routine rehabilitation.Methods From June,2020 to June,2022,18 patients with lateral ankle sprain in Kunshan Rehabilitation Hospital underwent routine rehabilitation for twelve weeks.They were measured active and passive position sense of bilateral ankles using an isokinetic dynamometer before treatment,and four,eight and twelve weeks after treatment,respectively.Results The active presentation difference of affected ankle reduced after treatment(F=22.533,P<0.001),but it was more than that of the healthy ankle at the same time(t>4.419,P<0.001).No significant improvement was found in passive presentation difference of affected ankle after treatment(F=1.175,P>0.05),and it was not significantly different from those of the healthy ankle at the same time(|t|<0.646,P>0.05).Conclusion Proprioception of affected ankle has been impaired after lateral ankle sprain,and it can be recovered after rehabilitation,but cannot achieve the healthy level even after three months of training.Passive position sense as an index of proprioception needs more researches.
