Women with premenstrual syndrome (PMS) are more likely to have spinal dysfunction, compared with PMS-free women,. Investigators examined 54 women with PMS and 30 women without PMS. All subjects were evaluated for 12 parameters of spinal dysfunction. PMS sufferers averaged 5.4 positive indexes. In contrast, control participants averaged 3.0 positive indexes. This dichotomy was statistically significant for back tenderness, low back orthopedic testing, low back muscle weakness, and the neck disability index.
The report concluded that, "A relatively high incidence of spinal dysfunction exists in PMS sufferers compared with a comparable group of non-PMS sufferers. This is suggestive that spinal dysfunction could be a causative factor in PMS and that chiropractic manipulative therapy may offer an alternative therapeutic approach for PMS sufferers."

Within the limitations of the study, the results support the hypothesis that the symptoms associated with PMS can generally be reduced by chiropractic treatment consisting of adjustments and soft-tissue therapy. However, the role of a placebo effect needs further elucidation, given that the group receiving the placebo first, although improving over the baseline, showed no further improvement when they had actual treatment.
