ORLANDI, Aline Cristina et al. Improvement in pain, fatigue, and subjective sleep quality through sleep hygiene tips in patients with fibromyalgia. Rev. Bras. Reumatol. [online]. 2012, vol.52, n.5, pp. 672-678. ISSN 0482-5004. http://dx.doi.org/10.1590/S0482-50042012000500003.
OBJECTIVE: To evaluate the effectiveness of sleep hygiene instructions for women with fibromyalgia. MATERIALS AND METHODS: Seventy women with fibromyalgia completed the study. The assessment comprised the Fibromyalgia Impact Questionnaire (FIQ), the Pittsburgh Sleep Quality Index (PSQI), and a general questionnaire with personal data and lifestyle information. All patients received information about the disease and a sleep diary, but only the experimental group received the sleep hygiene instructions. Patients were asked to practice sleep hygiene, and, after three months, they were reevaluated by use of the same questionnaires. RESULTS: The mean age in the control group was 55.2 ±7.12 years, and, in the experimental group, 53.5 ±8.89 years (P = 0.392). The experimental group showed: a decrease in the pain Visual Analogue Scale values (P = 0.028), in fatigue (P = 0.021), and in the PSQI component 1 (P = 0.030); and a significant reduction in the difficulty falling asleep after waking up in the middle of the night (P = 0.031). The experimental group also showed an increase in the reporting percentage of "silent environment" (ranging from 42.9% to 68.6%), a decrease in the reporting percentage of "fairly quiet environment" (ranging from 40% to 22.9%), and a decrease in the reporting percentage of "noisy environment" (ranging from 17.1% to 8.6%). These changes facilitated falling asleep after waking up in the middle of the night. CONCLUSION: The sleep hygiene instructions allowed changing the patients' behavior, which resulted in pain and fatigue improvement, increased subjective quality of sleep, in addition to facilitating falling asleep after waking up in the middle of the night.
