OBJECTIVES: To compare the cognitive function performance in patients with fibromyalgia (FM) with respect healthy controls and to evaluate the short-term efficacy of exercise therapy in a warm, chest-high pool on pain and cognitive function in women with FM.
METHODS: Sixty middle-aged women with FM were randomly assigned to either an exercise training group (n = 35) to perform 3 sessions per week of aquatic training (32 degrees C) including mobility, aerobic, strengthening, and relaxation exercises for 16 weeks, or a control group (n = 25). Twenty-five healthy women matched for age, weight, body mass index, and educational and physical activity levels were recruited. Pain was assessed in patients using a syringe calibrated like a pressure dolorimeter, and a visual analog scale. The severity of FM was evaluated using the Fibromyalgia Impact Questionnaire. Cognitive function was measured in healthy individuals and patients using several standardized neuropsychological tests. All patients were measured at baseline and post-treatment.
RESULTS: At baseline, the healthy group evidenced cognitive performance that was significantly superior to the group of patients with FM in all of the neuropsychological tests. The exercise group significantly improved their pain threshold, tender point count, self-reported pain, severity of FM, and cognitive function, while in the control group the differences were not significant.
CONCLUSION: An exercise therapy three times per week for 16 weeks in a warm-water pool is an adequate treatment to decrease the pain and severity of FM well as to improve cognitive function in previously unfit women with FM and heightened painful symptomatology.
To evaluate the effects of a 16-week exercise therapy in a chest-high pool of warm water through applicable tests in the clinical practice on the global symptomatology of women with fibromyalgia (FM) and to determine exercise adherence levels.
DESIGN:
A randomized controlled trial.
SETTING:
Testing and training were completed at the university.
PARTICIPANTS:
Middle-aged women with FM (n=60) and healthy women (n=25).
INTERVENTION:
A 16-week aquatic training program, including strength training, aerobic training, and relaxation exercises.
MAIN OUTCOME MEASURES:
Tender point count (syringe calibrated), health status (Fibromyalgia Impact Questionnaire); sleep quality (Pittsburgh Sleep Quality Index); physical (endurance strength to low loads tests), psychologic (State Anxiety Inventory), and cognitive function (Paced Auditory Serial Addition Task); and adherence 12 months after the completion of the study.
RESULTS:
For all the measurements, the patients showed significant deficiencies compared with the healthy subjects. Efficacy analysis (n=29) and intent-to-treat analysis (n=34) of the exercise therapy was effective in decreasing the tender point count and improving sleep quality, cognitive function, and physical function. Anxiety remained unchanged during the follow-up. The exercise group had a significant improvement of health status, not associated exclusively with the exercise intervention. There were no changes in the control group. Twenty-three patients in the exercise group were exercising regularly 12 months after completing the program.
