The efficacy of lumbar traction in the management of patients with low back pain.

The literature on the efficacy of traction in the treatment of low back pain (LBP) is conflicting. The aim of this study was to examine its efficacy in this disorder. Forty-two patients with at least 6 weeks of nonspecific LBP were selected. Demographic data were obtained. All patients completed the Oswestry disability index (ODI) to assess disability and the 10-cm visual analog scale (VAS) for evaluation of pain. Subjects were randomly assigned into group 1, receiving only standard physical therapy, or group 2, receiving standard physical therapy with conventional lumbar traction. Standard physical therapy consisted of local heat, ultrasound for the lumbar region, and an active exercise program, given for ten sessions in all. The subjects received instruction on correct posture and recommended therapeutic exercises. They were reevaluated at the end of treatment and at 3-month follow-up. The mean outcome measures were global improvement and satisfaction with the therapy, as well as disability by ODI and pain by VAS. There were no group differences in terms of demographic and baseline clinical characteristics. There was a significant reduction in pain intensity and disability at the end of treatment in both groups. There was complete or mild improvement in 47.6% of group 1 and 40% of group 2. The satisfaction rate with both treatments was more than 70% immediately after the therapies. During the 3-month period, the outcome measures except disability remained statistically stable, with no difference amongst groups. Disability was significantly reduced at follow-up in both groups. Of the patients, 51% continued with the recommended exercises and had significantly lower disability scores than those who did not continue with the exercises. Pain and global improvement were also better in this group, but the difference was not statistically significant. In conclusion, no specific effect of traction on standard physical therapy was observed in our study group. We suggest focusing on back education and exercise therapy in the management of patients suffering from this chronic condition.
