Effects of Exergames in Women with Fibromyalgia: A Randomized Controlled Study.

Evaluation of the effects of exergames in women with fibromyalgia on the impact of the disease-pain threshold and physical variables-compared to performing stretching exercises. Thirty-five women were enrolled in the study and divided by simple randomization into two treatment groups: the control group ( = 19) and the Wii™ (exergames) group ( = 16). Participants were evaluated using the fibromyalgia impact questionnaire (FIQ), algometry, step tests, cardiopulmonary parameters, and fatigue in the lower limbs. The participants underwent treatments for a period of 7 weeks with three 1-hour sessions weekly and were reevaluated after the 10th and the 20th sessions. The exergames group showed significant reduction of their fibromyalgia symptoms, as demonstrated by lower FIQ scores in the key domains on questions regarding missed work, pain, fatigue, problems resting, stiffness, anxiety, and depression. Significant improvements were observed in mean algometric values in the cervical region, the second chondrocostal junction, the lateral epicondyle, left medial knee border, left occipital region, trapezius, supraspinatus, gluteal muscles, and the greater trochanter. Improved cardiovascular adaptation was reflected by decreased systolic blood pressure, reduction in fatigue of the lower limbs assessed by the CR10 Borg scale, and improved exercise capacity assessed by a step test. Exergames have the potential to increase exercise capacity, decrease the impact of fibromyalgia, promote cardiovascular adaptation, reduce fatigue of lower limbs, and improve the pain threshold in women with fibromyalgia.
