To investigate the effect of ultrasound in the treatment of osteoarthritis of the knee.
Eighty-seven out- and in-patients with osteoarthritis of the knee (15 men and 72 women) underwent ultrasonic therapy from February to October 2010. The patients were randomly assigned to an ultrasound group (Group A) and a placebo group (Group B). Group A was offered ultrasonic therapy while Group B underwent mock treatment. The visual analogue scale (VAS) and Lequesne scores of the two groups before and after treatment were compared. The data were analyzed by normal distribution, Student's t-test and the rank sum test. The means during and after treatment of the VAS and Lequesne efficacy index of the treatment group were calculated and plotted on a bar graph.
Single sample analysis of Groups A and B showed VAS efficacy index: mean = 0.3640, P= 0.000; Lequesne efficacy index, median = 0.3080, P= 0.000, and mean = 0.1000, P= 0.000; Lequesne efficacy index, mean = 0.0364, P= 0.024, respectively. Independent samples t test and rank sum test showed significant differences between the two groups, namely P= 0.000 for both the VAS and Lequesne curative effect indexes. The means of the VAS efficacy index of the treatment group increased during and after treatment. The means of the Lequesne efficacy index of the treatment group showed no apparent decrease by 28 days after treatment.
Ultrasound treatment significantly alleviates joint symptoms, relieving joint swelling, increasing joint mobility and reducing inflammation, in osteoarthritis patients.
探讨超声治疗膝骨关节炎的效果。
2010 年 2 月至 10 月，对 87 例门诊和住院膝骨关节炎患者（男 15 例，女 72 例）进行超声治疗。患者随机分为超声组（A 组）和安慰剂组（B 组）。A 组接受超声治疗，B 组接受模拟治疗。比较两组治疗前后的视觉模拟评分（VAS）和 Lequesne 评分。数据采用正态分布、Student's t 检验和秩和检验进行分析。计算治疗组 VAS 和 Lequesne 疗效指数在治疗期间和治疗后的均值，并绘制条形图。
对 A 组和 B 组进行单样本分析，VAS 疗效指数：均数=0.3640，P=0.000；Lequesne 疗效指数，中位数=0.3080，P=0.000，均数=0.1000，P=0.000；Lequesne 疗效指数，均数=0.0364，P=0.024。独立样本 t 检验和秩和检验显示两组差异均有统计学意义，即 VAS 和 Lequesne 疗效指数的 P 值均为 0.000。治疗组 VAS 疗效指数在治疗期间和治疗后均增加。治疗组 Lequesne 疗效指数在治疗后 28 天未见明显下降。
超声治疗可显著缓解膝骨关节炎患者的关节症状，减轻关节肿胀，增加关节活动度，减轻炎症。
