Abstract
The purpose of this study was to test the hypothesis that positional distraction provides immediate relief of unilateral leg pain suspected to be caused by lumbar-nerve root irritation. Thirty subjects with true neurological signs were randomly assigned to a treatment group or control group. The treatment group received positional distraction for five minutes and the control group lay in side-lying for the same amount of time. Pain intensity, pain location, and SLR test height data was taken pre- and post-test. Statistical analysis was completed with the Wilcoxin-signed rank test for the data of pain intensity and with the paired sample t-test for the SLR height. The treatment group was found to have significantly less pain, more centralization of pain, and an increase in SLR test height (p-values of 0.001, 0.006, and 0.005 respectively). The control group showed no significant change (p-values of 0.506, 0.480, 0.884).
