放射状冲击波治疗膝骨关节炎的临床研究

The Clinical Study of Radial Shock Wave Therapy in the Treatment of Knee Osteoarthritis

目的:分析体外放射状冲击波(RSWT)治疗膝骨关节炎(KOA)的临床效果。方法:将确诊为膝骨关节炎的患者106例,按随机数字表法分为对照组51例和研究组55例。对照组采用传统的超声波治疗,研究组采用RSWT治疗。分别在治疗前及治疗结束时、治疗后1周、治疗后1个月采用视觉类比疼痛评分(VAS)及膝关节功能评分(Lysholm)评价其临床疗效,治疗期间均需观察患者出现的不良反应。结果:治疗结束时及治疗后1周,研究组和对照组患者的VAS和Lysholm评分较治疗前均明显改善,差异均有统计学意义(P<0.05),但两组比较差异均无统计学意义(P>0.05)。治疗后1个月,对照组患者的VAS评分较治疗前有明显改善(P<0.05),Lysholm评分与治疗前比较虽有所下降,但差异无统计学意义(P>0.05);研究组患者VAS和Lysholm评分均优于治疗前及对照组,差异均有统计学意义(P<0.05)。对照组的不良反应发生率为3.9%(2/51),与研究组的3.6%(2/55)比较,差异无统计学意义(P>0.05)。结论:放射状冲击波治疗膝骨关节炎是一种安全有效、患者易于接受的物理疗法。

Objective：To analyze the clinical efficacy of radial shock wave therapy （RSWT）in the treatment of knee osteoarthritis （KOA）.Method：A total of 106 patients with knee osteoarthritis were randomly divided into the control group （51 cases） and the study group （55 cases）.The control group was treated with traditional ultrasound therapy,and the study group was treated with RSWT.Respectively before and after treatment,1 week and 1 month after treatment,the visual analog pain score （VAS） and knee function score （Lysholm） were used to evaluate its clinical efficacy,the adverse effects of the two groups were observed during the treatment period.Result：At the end of treatment and 1 week after treatment,VAS and Lysholm scores in the study group and the control group were significantly improved than those before treatment,the differences were statistically significant（P〈0.05）,but there were no significant differences between the two groups（P〉0.05）.1 month after the treatment,the VAS score of the control group was significantly improved （P〈0.05）,compared with before treatment,but the Lysholm score was lower than that before treatment,but the difference was not statistically significant（P〉0.05）;the VAS and Lysholm scores of the patients in the study group were better than those before treatment and the control group,the differences were statistically significant（P〈0.05）.The incidence of adverse reactions in the control group was 3.9%（2/51）,compared with 3.6%（2/55） in the study group,there was no significant difference（P〉0.05）.Conclusion：Radial shock wave is a safe,effective and physically acceptable treatment for osteoarthritis of the knee.
