Pilates Exercises in Spanish Women With Fibromyalgia

To analyze the effects of a Pilates exercise program in Spanish postmenopausal women with Fibromyalgia

This is a randomized clinical trial of single-blind with 2 arms (Control group and experimental group), in which a pre-treatment-postest design has been used. The study will define two groups: A control group (CG) that will not be submitted to treatment, which will be evaluated in the pre and post phase of the study. Participants assigned to this group will receive general advice on the positive effects of regular physical activity and will be given a guide to recommendations for promoting physical activity. An experimental group (GE) that after an initial evaluation will undergo a physical training program based on Pilates exercises. Once the intervention is finished, it will be submitted to a final evaluation to see if there is a difference or not with the results obtained at the beginning.

The assignment to the groups will be of simple random type and hidden. Those responsible for admitting patients to the intervention phase will not know what group has been assigned each. This assignment will be made in advance by a researcher who will not intervene in the later stages of evaluation, intervention, data recording and elaboration of database. The assignment will be communicated through sealed and totally opaque envelopes. All measurements given above will be made both to the control group and to the experimental group just prior to the start of the intervention, and immediately after and six months after the end of this period, and the results will be recorded in a data record

The duration of the intervention is 12 weeks, with 2 sessions per week of Pilates. Each session lasts approximately 1 hour and is structured in three parts: initial warm-up, which reviews the basic principles of the Pilates Method (centralization, concentration, movement control, breathing, movement precision and fluency) of 10 minutes duration, a 40-45 minute Pilates session and finally 10 minutes of guided relaxation. No complement was used (magic rings, fitball, elastic bands, etc.) during classes

Questionnaire that assesses balance confidence in performing activities of daily living. It is calculated by adding up the 16 responses of the questionnaire, with 0 being the minimum score and 100 being the maximum score. The higher value represents a better result.

Questionnaire that evaluates the fear of falling. It is calculated by adding up all the answers in the questionnaire, 16 being the minimum score and 64 the maximum score. The higher value represents a worse result.

A self-report scale describing the severity of fatigue and the impact of fatigue on activities of daily living. It is calculated by adding up the 9 answers of the questionnaire, being 9 the minimum score and 63 the maximum score. The higher value represents a worse result.

A questionnarie that evaluates the impact of fibromyalgia on the patient's quality of life.The total score is the addition of the scores of all its sections. In the case that there were left some unanswered, all the other ones are added up and the score is divided by the number of items answered and multiplied by 10, with the result that the final score of the FIQ is from 0 to 100. A higher score means a greater impact of the disease on the patient.

Fatigue assessed by a Visual Analogue Scale (10 cm). The patient marks the intensity of the fatigue on a numerical scale of 0-10, with 0 being the minimum score and 10 being the maximum score. The higher value represents a worse result.

Pain assessed by a Visual Analogue Scale (10 cm). The patient on a numerical scale of 0-10 marks the intensity of the pain, with 0 being the minimum score and 10 the maximum score. The higher value represents a worse result.

A simple and valid assessment of both sleep quality and disturbance that might affect. They consist of 10 questions divided into four subscales: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep discomfort, medication use and daytime dysfunctions, adding up to a total score. The higher value represents a worse result.

A reliable, valid and practical screening tool for identifying and quantifying anxiety and/or depression in non- patients. It is calculated by the sum of the 14 questions in the questionnaire divided into two subscales: anxiety (questions 1, 3, 5, 7, 9, 11, 13) and depression (questions 2, 4, 6, 8, 10, 12, 14). The higher value represents a worse result.

Used extensively for assessing health-related quality of life. It is calculated by adding the 36 questionnaires divided into 9 subscales: general health, health change, physical function, physical role, role or emotional performance, social function, physical or body pain, vitality and mental health. Each item is rated 0-1-2-3-4 points with 0 being the best score.

Valid and reliable tool to quantify and measure the 4 major components of body composition: Water, Protein, Minerals and Fat

Is computed based on muscle mass of the limbs, which is almost composed of skeletal muscle and takes up about 70% of total body skeletal muscle

The standard range of Body Fat Mass is ascertained by calculating an examinee Body Fat Mass as compared to the standard weight and standard Body Fat Mass

Is calculated from the formula, Weight (kg) / Height2 (m2), whose unit is kg/m2. It is a rough indicator of total body fat

Is the technology that assumes the body as five cylinders of four limbs and trunk and measures the impedance of these parts separately. Segmental body composition analysis provides segmental measurement of body water, muscle mass, and fat free mass

assesses the severity of menopause-related complaints and the impact on health-related quality of life. Calculated by adding up the 11 questions in the questionnaire. Each item has a score of 0-1-2-3-4, with 4 being the worst score.

instrument composed of resistive pressure sensors, used to measure the static or postural balance. The test was performed under both eyes-open and eyes-closed conditions

Is an estimate of the average velocity of displacement of the center of pressures of the subject during the whole test

Is the dimensionless ratio of the circumference of the waist to that of the hips. This is calculated as waist measurement divided by hip measurement
