OBJECTIVE: To evaluate the effects of pool exercise in patients with fibromyalgia
and chronic widespread pain and to determine characteristics influencing the
effects of treatment. METHODS: A total of 134 women with fibromyalgia and 32 with
chronic widespread pain were randomized to a 20-session pool exercise and a
6-session education programme or to a control group undertaking the same
education programme. The primary outcomes were the Fibromyalgia Impact
Questionnaire (FIQ) total score and the 6-minute walk test (6MWT). FIQ Pain and
other health variables were included. RESULTS: The FIQ total (p = 0.04) improved
in the intervention group, with an effect size of 0.32. Patients who had
participated in at least 60% of the exercise sessions improved in the FIQ total
(effect size 0.44), the 6MWT (effect size 0.43) and FIQ Pain (effect size 0.69)
compared with controls (p < 0.05). Long-term follow-up revealed lasting, but
small, improvement (effect size < 0.29) in the 6MWT among the active participants
(p < 0.05). Analyses within the subgroups showed that patients with milder
stress, pain or depression improved most by treatment on the FIQ total (effect
size > 0.50, p < 0.05) compared with controls. CONCLUSION: The exercise-education
programme showed significant, but small, improvement in health status in patients
with fibromyalgia and chronic widespread pain, compared with education only.
Patients with milder symptoms improved most with this treatment.
