The study aimed to investigate the effect of an 8-wk structured
strength training program on pain and sleep quality in patients with fibromyalgia. DESIGN: Fifty-two patients with fibromyalgia were evaluated; 31
submitted to strength training and 21 comprised the control group. The
instruments used were the Fibromyalgia Impact Questionnaire and The Pittsburgh
Sleep Quality Index. The questionnaires were applied before the first training
session, at 12 sessions, and after 24 sessions.
Descriptive statistics (mean, SD,
and frequency) and inferential tests were used.
RESULTS: After 8 wks of
intervention, significant differences were found between groups in subjective
quality of sleep (P = 0.03), sleep disturbance (P = 0.02), daytime dysfunction (P
= 0.04), and total sleep score (P < 0.01). The correlation analysis using
Spearman's test indicated a positive relationship between the variables of pain
intensity and sleep quality (P < 0.01); when pain intensity increased in patients
with fibromyalgia, sleep quality worsened. CONCLUSIONS: Strength training is safe
and effective in treating people with fibromyalgia, and a significant decrease in
sleep disturbances occurs after 8 wks of intervention.
