A prospective, randomized, single (investigator) blind, comparative efficacy trial was conducted.
To compare the efficacy of continuous low-level heat wrap therapy (40 C, 8 hours/day) with that of ibuprofen (1200 mg/day) and acetaminophen (4000 mg/day) in subjects with acute nonspecific low back pain.
The efficacy of topical heat methods, as compared with oral analgesic treatment of low back pain, has not been established.
Subjects (n = 371) were randomly assigned to heat wrap (n = 113), acetaminophen (n = 113), or ibuprofen (n = 106) for efficacy evaluation, or to oral placebo (n = 20) or unheated back wrap (n = 19) for blinding. Outcome measures included pain relief, muscle stiffness, lateral trunk flexibility, and disability. Efficacy was measured over two treatment days and two follow-up days.
Day 1 pain relief for the heat wrap (mean, 2) was higher than for ibuprofen (mean, 1.51; P = 0.0007) or acetaminophen (mean, 1.32; P = 0.0001). Extended mean pain relief (Days 3 to 4) for the heat wrap (mean, 2.61) also was higher than for ibuprofen (mean, 1.68; P = 0.0001) or acetaminophen (mean, 1.95; P = 0.0009). Lateral trunk flexibility was improved with the heat wrap (mean change, 4.28 cm) during treatment (P </= 0.009 vs acetaminophen [mean change, 2.93 cm], P </= 0.001 vs ibuprofen [mean change, 2.51 cm]). The results were similar on Day 4. Day 1 reduction in muscle stiffness with the heat wrap (mean, 16.3) was greater than with acetaminophen (mean, 10.5; P = 0.001). Disability was reduced with the heat wrap (mean, 4.9), as compared with ibuprofen (mean, 2.7; P = 0.01) and acetaminophen (mean, 2.9; P = 0.0007), on Day 4. None of the adverse events were serious. The highest rate (10.4%) was reported in the ibuprofen group.
Continuous low-level heat wrap therapy was superior to both acetaminophen and ibuprofen for treating low back pain.
进行了一项前瞻性、随机、单(研究者)盲、比较疗效试验。
比较连续低水平热裹疗法(40摄氏度,每天8小时)与布洛芬(每天1200毫克)和对乙酰氨基酚(每天4000毫克)治疗急性非特异性下腰痛患者的疗效。
与口服镇痛药治疗下腰痛相比,局部热疗方法的疗效尚未确定。
将受试者(n = 371)随机分配至热裹组(n = 113)、对乙酰氨基酚组(n = 113)或布洛芬组(n = 106)进行疗效评估,或分配至口服安慰剂组(n = 20)或未加热的背部裹敷组(n = 19)进行盲法对照。观察指标包括疼痛缓解、肌肉僵硬、侧躯干柔韧性和功能障碍。在两个治疗日和两个随访日测量疗效。
热裹组第1天的疼痛缓解程度(平均值为2)高于布洛芬组(平均值为1.51;P = 0.0007)和对乙酰氨基酚组(平均值为1.32;P = 0.0001)。热裹组延长的平均疼痛缓解程度(第3至4天,平均值为2.61)也高于布洛芬组(平均值为1.68;P = 0.0001)和对乙酰氨基酚组(平均值为1.95;P = 0.0009)。治疗期间热裹组的侧躯干柔韧性得到改善(平均变化4.28厘米)(与对乙酰氨基酚组相比,P≤0.009[平均变化2.93厘米];与布洛芬组相比,P≤0.001[平均变化2.51厘米])。第4天的结果相似。热裹组第1天肌肉僵硬程度的降低(平均值为16.3)大于对乙酰氨基酚组(平均值为10.5;P = 0.001)。与布洛芬组(平均值为2.7;P = 0.01)和对乙酰氨基酚组(平均值为2.9;P = 0.0007)相比,热裹组在第4天功能障碍程度降低。所有不良事件均不严重。布洛芬组报告的发生率最高(10.4%)。
连续低水平热裹疗法在治疗下腰痛方面优于对乙酰氨基酚和布洛芬。
