目的观察并评价聚焦式超声对于腰骶部慢性软组织损伤的治疗效果。方法采用随机数字法把152例腰骶部软组织损伤患者随机分为对照组73例与超声治疗组79例。对照组采用局部痛点阻滞进行治疗,每周治疗1次,持续治疗3周。超声治疗组采用聚焦式超声进行治疗,每日治疗1次,隔日治疗,连续治疗5次。选取治疗前、首次治疗10min后、疗程结束1d后与疗程结束3个月后进行VAS评分,并进行统计、分析临床疗效。结果超声组与对照组在首次治疗后10min、疗程结束后1d、疗程结束后3个月的VAS评分均比治疗前有所降低(P<0.01),但超声组在疗程结束后1d与疗程结束后3个月的VAS评分明显低于对照组(P<0.01),且超声组在3个时间点的总体疗效明显高于对照组(P<0.05)。结论聚焦式超声在治疗腰骶部软组织损伤中疗效持久、显著,相比于局部痛点阻滞疼痛复发率显著降低,值得临床推广。 Objective To observe and evaluate the therapeutic effect of focused ultrasound on chronic lumbosacral soft tissue injury. Methods 152 patients with lumbosacral soft tissue injury were randomly divided into control group (n = 73) and ultrasound group (n = 79) using random number method. The control group was treated with local pain point block, treatment once a week, continuous treatment for 3 weeks. Ultrasound treatment group using focused ultrasound treatment, daily treatment 1, every other day treatment, continuous treatment 5 times. Select the treatment, the first treatment after 10min, 1d after the end of treatment and end of treatment after 3 months VAS score, and statistics, analysis of clinical efficacy. Results The VAS scores of the ultrasound group and the control group at 10 min after the first treatment, 1 d after the end of treatment and 3 months after the end of the treatment were both lower than those before treatment (P <0.01) The VAS score of the latter 3 months was significantly lower than that of the control group (P <0.01), and the overall curative effect of the ultrasound group at 3 time points was significantly higher than that of the control group (P <0.05). Conclusion Focused ultrasound in the treatment of lumbosacral soft tissue injury lasting effect, significant, compared with the local pain point block pain recurrence rate was significantly reduced, worthy of clinical promotion.
