关节松动术联合PNF训练对膝关节骨性关节炎临床疗效分析

Clinical Effect of Joint Loosening Combined with PNF Training on Knee Osteoarthritis

摘要: 目的：通过临床随机对照观察关节松动术联合PNF对膝骨性关节炎的临床康复疗效分析。方法：选取60例膝关节骨性关节炎患者为受试者。将符合纳入标准的受试者随机数字表法随机分为A、B、C组，A组接受关节松动术训练；B组接受PNF训练；C组接受关节松动术和PNF训练。对所有受试者，分别在治疗前和治疗4周行膝关节Lysholm评分和膝关节伸屈肌的峰力矩评定。结果：3组治疗前膝关节Lysholm评分和膝关节伸屈肌的峰力矩评定无统计学意义(P > 0.05)。A组治疗后膝关节Lysholm评分和膝关节伸屈肌的峰力矩评定优于治疗前，差异有统计学意义(P < 0.05)；B组治疗后膝关节Lysholm评分和膝关节伸屈肌的峰力矩评定优于治疗前，差异有统计学意义(P < 0.05)；C组膝关节Lysholm评分和膝关节伸屈肌的峰力矩评定优于治疗前，差异有统计学意义(P < 0.05)。A组和B组治疗后膝关节Lysholm评分和膝关节伸屈肌的峰力矩评定差异无统计学意义(P > 0.05)，C组治疗后Lysholm评分和膝关节伸屈肌的峰力矩优于A组，比较差异有统计学意义(P < 0.05)，C组治疗后Lysholm评分和膝关节伸屈肌的峰力矩评定优于B组，差异有统计学意义(P < 0.05)，C组对膝关节的功能改善和伸屈肌肉力量增加更明显。结论：关节松动术和PNF训练都能一定程度改善膝关节功能和力量，关节松动术联合PNF训练对膝关节骨性关节炎的治疗疗效明显优于其中一种技术，值得临床推广应用。

Abstract: Objective: To observe the clinical rehabilitation effect of joint mobilization combined with PNF in patients with knee osteoarthritis through clinical randomized trial. Methods: Sixty patients with knee osteoarthritis meeting the inclusion were randomly divided into group A, B and C groups. Pa-tients in group A received joint mobilization training. Patients in group B received PNF training; Pa-tients in group C received joint mobilization and PNF training. For all subjects, knee Lysholm score and knee extensor muscle peak torques were assessed before and at 4 weeks after treatment. Re-sults: There were no statistical significances in Lysholm score of knee joint and peak moment of knee extensor muscle before treatment in 3 groups (P > 0.05). Lysholm score of knee joint and peak moment of knee extensor muscle in group A after treatment were better than before treatment, the differences were statistically significant (P < 0.05). The lysholm score of knee joint and peak mo-ment of knee extensor muscle in group B after treatment were better than before treatment, the differences were statistically significant (P < 0.05). Lysholm score of knee joint and peak moment of knee extensor muscle in group C after treatment were better than before treatment, the differences were statistically significant (P < 0.05). There were no significant differences in Lysholm score of knee joint and peak torque of knee flexor extensor after treatment between group A and group B (P > 0.05), while Lysholm score of knee joint and peak torque of knee flexor extensor after treat-ment in group C were better than that in group A and group B (P < 0.05). Conclusion: Both joint mo-bilization and PNF training can improve the function and strength of knee joint. Joint mobilization combined with PN F training has significantly better therapeutic effect on knee osteoarthritis than either of the two techniques, which is worthy of clinical application.
