Abstract
Objective: To evaluate the effectiveness of the Mitchell Method Relaxation Technique (MMRT) in reducing symptoms of fibromyalgia. Design: A randomised controlled trial was used to compare the effectiveness of self-administered MMRT (n= 67) with attention control (n = 66) and usual care (n = 56) groups. Main Outcome Measures: Primary outcomes included self-reported fatigue, pain, and sleep. Secondary outcomes were daily functioning, quality of life, depression, and coping, anxiety and perceived stress. Outcomes were assessed at baseline, post-intervention (four weeks) and follow-up (eight weeks). Results: A significant combined improvement on outcomes (p<.005), specific significant effects for sleep problems (d=0.29, p<.05), sleep inadequacy (d=0.20, p<.05), and fatigue (d=0.47, p<.05) were present in the MMRT group. At the follow-up, fatigue did not differ to the post-intervention score (p=.25) indicating short-term sustainability of the effect. The effects on sleep problems and sleep inadequacy were not sustained. The pain levels decreased when the MMRT was practiced three times a week (p<.001). Conclusion: MMRT was effective in reducing pain, sleep problems, and fatigue. High rates of relative risk reduction for fatigue (37%) and pain (42.8%) suggest clinical significance.
