OBJECTIVE
The purpose of this study was to compare the effects of end range loading (ERL) vs harmonic technique (HT) on patients with chronic low back pain (LBP).
METHOD
Fourteen volunteer patients with LBP were randomly assigned to 2 groups based on a blocked randomization method with 7 patients in the HT group and 7 patients in the ERL group. The patients received 10 sessions of treatment for 5 sessions per week. Pain intensity and disability score were recorded using the numeric pain scale and Roland-Morris Disability questionnaire (RMQ), respectively, before and after the treatment period.
RESULTS
Although pain intensity (P = .02) and the RMQ score (P = .03) decreased in the HT technique group, no statistically significant change was found in the ERL group for the RMQ score (P > .05). The effect size for HT was .6 and .3 for numeric pain scale and RMQ, respectively.
CONCLUSION
This preliminary study showed that pain intensity and disability improved in subjects with chronic LBP in the HT group. More investigations with larger sample size are needed to clarify these findings.
目的
本研究旨在比较终末范围负荷（ERL）与谐波技术（HT）对慢性下腰痛（LBP）患者的影响。
方法
14名LBP志愿者患者根据区组随机化方法随机分为2组，HT组7例，ERL组7例。患者接受10次治疗，每周5次。在治疗期前后分别使用数字疼痛量表和罗兰-莫里斯残疾问卷（RMQ）记录疼痛强度和残疾评分。
结果
虽然HT技术组的疼痛强度（P = .02）和RMQ评分（P = .03）降低，但ERL组的RMQ评分未发现统计学上的显著变化（P > .05）。HT技术在数字疼痛量表和RMQ上的效应量分别为.6和.3。
结论
这项初步研究表明，HT组慢性LBP患者的疼痛强度和残疾状况有所改善。需要更多大样本量的研究来阐明这些发现。
