Effect of craniosacral therapy on the intensity of chronic back pain of nurses: A randomized controlled trial

Background & Aim: Chronic low back pain is a common disease among nurses. According to the literature, complementary medicine can reduce low back pain, one of which is craniosacral therapy. This study was designed to investigate the effect of craniosacral therapy on the intensity of chronic back pain of nurses. Methods & Materials: This randomized clinical trial study was conducted on 60 nurses with chronic back pain. The participants were randomly assigned into intervention and control groups. The intervention group's participants received eight individual sessions of craniosacral therapy. In the control group, a light-touch in the lumbar region was performed as a placebo. The therapist met each participant separately in a private room of the hospital. The two groups completed the McGill Pain Questionnaire at the baseline, immediately after the intervention, and one month after the intervention. The collected data was analyzed in SPSS (v.16) using descriptive and analytical tests such as t-test, ChiSquare, ANCOVA, and repeated measures ANOVA. Results: The ANCOVA test results showed a significant difference between the two groups' mean scores of pain intensity and its subscales (P<0.05). The results of repeated measures ANOVA showed that the mean scores of pain intensity and its subscales (sensory, affective, pain evaluation, and miscellaneous) decreased over the three time points in the intervention group (P<0.05). Conclusion: The findings affirmed the positive effects of the craniosacral therapy on the intensity of pain in nurses with chronic back pain. Therefore, it is recommended that this approach be performed as a complementary, effective, non-invasive intervention to decrease chronic back pain.
