前交叉韧带保残重建术后减重支持步行训练对膝关节位置觉的影响

Effects of early partial body weight support gait training on the topesthesia of the knee after anterior cruciate ligament reconstructions with remnant preservation

目的:探讨前交叉韧带保残重建术后早期减重支持步行训练对膝关节位置觉的影响。方法:将前交叉韧带保残重建术后患者41例分为对照组21例及治疗组20例,术后分别进行常规康复训练及附加减重支持步行训练。术后12周、6个月进行健患侧膝0°—20°、40°—60°、80°—100°被动角度重现测定。结果:术后12周及6个月两组健患侧膝之间位置重现试验差异均有显著性意义(P<0.05),6个月时健患侧膝之间位置觉成绩之差两组均较12周时进一步缩小,且治疗组差值小于对照组,3个角度中伸直、中间位时的位置觉差值有显著性意义。结论:前交叉韧带保残重建术后加入减重支持步行训练能早期对膝关节位置觉产生积极意义,可明显改善0—60°膝关节位置觉。

Objective： To evaluate the effects of early partial body weight support （PBWS） gait training on the topesthesia of the knee after anterior cruciate ligament reconstructions with remnant preservation. Method： Forty-one patients underwent anterior cruciate ligaments reconstructions with remnant preservation were divided into control group （n=21） and observation group （n=20）. They were given conventional rehabilita- tion trainings and additional PBWS gait training respectively. Position reappearance tests were recorded at 12 weeks and 6 months postoperatively. Result： There were significant differences of position reappearance between two groups at 12 weeks and 6 months follow-up （P〈0.05）. At 6-month-follow-up, the time gap of position reappearance between two sides of lower limbs decreased compared to 12-week-follow-up. Besides, these scores in observation group were even smaller than that in control group. The time gap of two sides of lower limbs were significantly different in two （extension, neutral） out of three positions. Conclusion： After anterior cruciate ligament reconstruction surgeries with remnant preservation, early introduc- tion to PBWS gait training can improve topesthesia recovery of knee joint, and it can significantly improve the topesthesia specifically regarding the positions about 0 to 60°.
