The purpose was to determine the efficacy of therapeutic ultrasound in patients with chronic low back pain. Thirty-one patients, age 38-77, with low back pain lasting more than three months and the intensity of pain on visual analogue scale at least 50 mm, are randomly divided in two groups. Ultrasound is applied on the lumbar paravertebral muscle in 16 patients and in 15 patients the machine was not switched on. All patients also underwent kinesitherapy. Pharmacological treatment was not changed during the research (except the possibility of using paracetamol as the "rescue drug"). Following parameters were measured at the beginning and at the end of the research: pain intensity on the visual analogue scale/mm, modified Schober measure/cm, patient's and physician's global assessment of treatment efficacy (1-5 scale). The intensity of pain in the ultrasound group before the treatment was 82,7+/-14,0 and after the treatment 79,8+/-12,2 (p<0,05). The intensity of pain in the placebo group before the treatment was 81,7+/-12,1 and at the end of the treatment 78,9+/-12,1 (p>0,05). The value of the modified Schober measure for the ultrasound group were 5,7+0,8 cm vs. 5,8+/-0,9 cm (p>0,05) and in the placebo group were 5,4+/-0,9 cm vs. 5,6+/-1,0 cm (p>0,05). There was no significant statistical difference between ultrasound and placebo group regarding the efficacy of the treatment (patients p>0,05, physicians p>0,05). Therapeutic ultrasound was effective in decreasing the pain intensity in this research, but showed no improvement regarding the functional ability of the lumbar spine in patients with chronic low back pain.
目的是确定治疗性超声对慢性下腰痛患者的疗效。31名年龄在38 - 77岁之间、下腰痛持续超过三个月且视觉模拟量表上的疼痛强度至少为50毫米的患者被随机分为两组。16名患者接受腰部椎旁肌超声治疗，15名患者未开启仪器。所有患者均接受了运动疗法。研究期间药物治疗不变（除了使用对乙酰氨基酚作为“急救药物”的可能性）。在研究开始和结束时测量以下参数：视觉模拟量表上的疼痛强度/毫米、改良Schober测量值/厘米、患者和医生对治疗效果的总体评估（1 - 5级）。超声组治疗前疼痛强度为82.7±14.0，治疗后为79.8±12.2（p<0.05）。安慰剂组治疗前疼痛强度为81.7±12.1，治疗结束时为78.9±12.1（p>0.05）。超声组改良Schober测量值为5.7±0.8厘米，而安慰剂组为5.8±0.9厘米（p>0.05）；安慰剂组分别为5.4±0.9厘米和5.6±1.0厘米（p>0.05）。在治疗效果方面，超声组和安慰剂组之间无显著统计学差异（患者p>0.05，医生p>0.05）。在本研究中，治疗性超声在降低疼痛强度方面有效，但在改善慢性下腰痛患者腰椎功能能力方面未显示出改善。
