Effects of Pain Therapeutic Education and Hydrotherapy on Physical Function, Pain and Sleep of Women With Fibromyalgia

Fibromyalgia (FM) is a prevalent and disabling disease, that affects mostly women and its main characteristic is chronic pain. Several studies have shown that hydrotherapy is effective in the improvement of symptoms and quality of life of this population; other studies have shown that Pain Therapeutic Education (PTE) is also effective in this sense. PTE is one cheap, easy to apply intervention, with very positive results in chronic pain situations. However, there is a lack of studies that have shown the effects of this intervention on FM. Hence, this study will aim to verify the effectiveness of the hydrotherapy and PTE on women with FM. Sixty women will be randomly allocated in two groups: hydrotherapy and hydrotherapy + PTE. Before treatment start, the investigators will evaluate pain (visual analogue scale, presence of myofascial trigger points and pressure pain threshold over the scalene, upper trapezius, infraspinatus, piriformis, iliopsoas and soleus, bilaterally), quality of life (Fibromyalgia Impact Questionnaire and medical outcomes study 36-item short-form health survey), depression (Beck Depression Inventory), anxiety (Beck Anxiety Inventory) and sleep quality (Pittsburgh Sleep Quality Index and Epworth Sleepiness Scale). Hydrotherapy treatment will last 12 weeks. Women will be evaluated other 3 times: after 6 and 12 weeks (treatment middle and end) and 12 weeks after treatment completion (follow-up). Women in the hydrotherapy group will receive a folder with explanations on FM. Women in the hydrotherapy + PTE will participate of 4 meetings over 12 treatment weeks, in which themes like pain physiology, pain chronification and exacerbation and pain self-management, as well as information on FM will be approached. Statistical analysis will include qualitative and quantitative variable description. Correlation among variables will also be analyzed. Level of significance will be set at 5%.
