DESIGN: Subjects were assessed with self-administered questionnaires taken at baseline, after 15 and 30 treatments, and 1 month after the end of the treatment trial.
SETTING: Private practice.
METHODS: Participating subjects were adult members of a regional Fibromyalgia Association. Participating subjects had fibromyalgia for more than 3 months. They received 30 treatments including ischemic compression and spinal manipulation. The 3 outcomes being evaluated were pain intensity, fatigue level, and sleep quality. A minimum 50 improvement in pain intensity from baseline to the end of the treatment trial was needed to include the patient in the respondent category.
RESULTS: Fifteen women (mean age 51.1 years) completed the trial. A total of 9 (60) patients were classified as respondents. A statistically significant lessening of pain intensity and corresponding improvement in quality of sleep and fatigue level were observed after 15 and 30 treatments. After 30 treatments, the respondents showed an average lessening of 77.2 (standard deviation = 12.3) in pain intensity and an improvement of 63.5 (standard deviation = 31.6) in sleep quality and 74.8 (standard deviation = 23. 1) in fatigue level. The improvement in the 3 outcome measures was maintained after 1 month without treatment. Subjects with less than 35 improvement after 15 treatments did not show a satisfactory response after 30 treatments. A trend, determined as not statistically significant, suggests that older subjects with severe and more chronic pain and a greater number of tender points respond more poorly to treatment.
CONCLUSION: This study suggests a potential role for chiropractic care in the management of fibromyalgia. A randomized clinical trial should be conducted to test this hypothesis.
