BACKGROUND: The effects of stretching exercises in fibromyalgia (FM) deserves further study. OBJECTIVE: To evaluate the effectiveness of a Physical Self-Care Support Program (PSCSP), with emphasis on stretching exercises, in the treatment of FM. METHODS: Forty-five women with FM were randomized to the PSCSP (n = 23) or to a control group (n = 22). The PSCSP consisted of weekly 90-minute learning sessions over 10 weeks, providing instructions on wellness, postural techniques, and active stretching exercises to be done at home. The control group was monitored through 3 medical appointments over 10 weeks and included in a waiting list. The primary outcomes were the Fibromyalgia Impact Questionnaire (FIQ), the Visual Analogue Scale (VAS) for pain, and the Sit and Reach Test (SRT) at the end of the study. RESULTS: Nineteen and 21 patients completed the trial in PSCSP and control groups, respectively. After 10 weeks, the PSCSP group showed significantly better FIQ (difference between adjusted means, -13.64, 95% CI -21.78 to -5.49, p = 0.002) and SRT scores (7.24 cm, 3.12 to 11.37, p = 0.001) than the control group, but no significant difference in pain VAS (-1.41 to -3.04 to 0.22, p = 0.088). Analysis using multiple imputation (MI) and delta-adjusted MI for missing outcomes rendered similar results. CONCLUSIONS: A PSCSP emphasizing stretching exercises significantly improved FIQ and SRT scores, and may be a helpful therapy for FM.
