Description of intervention(s) / exposure
People from the association will be informed about this study and will a receive a leaflet with information about the aim, content and duration of the study. Eligibility for study enrolment will be carried out by two physiotherapists with experience with working with patients with fibromyalgia. Study participants will sign an informed consent prior to the start of the study.

After study enrolment, participants will be allocated in either the ‘Pilates group’ or the ‘Stretching group’. Groups allocation (two groups of 30 patients) will be carried out by a computerised randomization program (randomized.com) that guarantees concealment for group allocation. A co-worker, not involved in this study will be responsible for this process. Baseline and outcome measures will be taken by physiotherapists blinded for group allocation. Analysis of study data will be carried out by a researcher not involved in this study.
The material used for the study was: a manual altimeter, a pressure cuff and electronic support for data recording. The physiotherapist who carried out the intervention was an outsider to whom he collected the data and different from the one who analyzed them. However, all physiotherapists are specialists in fibromyalgia.
Participants will complete a program of either Pilates or Stretching exercises for a period of three months.

Pilates group

A progressive exercise regimen will be given to the participants in the Pilates group. In the first month, sessions will consist of a set of specific Pilates exercises that will be repeated 6 times with a 40 second interval. During the following months, the number of repetitions will be increased to ten with only 15 seconds or rest between exercises. This program will follow the basic principles of the Pilates method with a special emphasis on movements with a low to intermediate difficulty. The frequency and duration of sessions will be 30 minute sessions, twice a week. The therapy will be surperved by a Pilates instructor with a degree in sports science and physiotherapy. The attendance and adherence of the treatment of each patient will be noted in a book of notes.
The performance protocol comprises several modules, which will be similar to those described by Altan: basic principles, breathing exercises, posture exercises, neutral position search, sitting exercises, antalgic exercises, stretching exercises and proprioceptivity exercises.

Stretching group

A stretching program targeting the following muscles will be given twice a week for 3 months: 1) paravertebral-, latissimus-, ischiotibial- ,gluteal muscles, hamstrings, hip adductors and triceps surae. Progression of stretching exercises in this group is: 3 repetitions in week 1 – 4, 4 repetitions in week 5 and 5 repetitions in week 6 – 12.
The study will be carry out in fibromyalgia association, Madrid , Spain.
Follow-up will be carried out in the assistance of patients to the study.
The therapy will be surperved by a Pilates instructor with a degree in sports science and physiotherapy. The attendance and adherence of the treatment of each patient will be noted in a book of notes

Outcomes
Primary outcome [1] 319729 0
Pain intensity – Subjective pain evaluation will be measured using a Numerical Pain Rating Scale (NPRS).

Baseline, postreatment, first, second, third, fourth month and follow up sixth month.
Secondary outcome [1] 369314 0
Pressure Pain Thresholds – Pressure pain threshold (UDP). A manual gauge (Wagner Force Dial FDK will be used. The operator increases the pressure (expressed in kg / cm2) on the skin of the patient. the patient indicates when he has reached his pain threshold, and when the pressure exerted at that point begins to be painful. The operator registers the indicated value in the elastometer at that moment. The exploration of a painful point or tender point in fibromyalgia is performed by calculating the average of two measurements made with an interval of 30 seconds.

Temporal Summation – It is the result of the application of the pressure obtained according to the PPT in which, by means of a scale of numerical evaluation, the subject will reflect the subjective pain perceived in the first pressure in the fifth and in the tenth.

Secondary outcome [3] 369316 0
Conditioned Pain Modulation – Modulation of pain before an external pressure stimulus (CPM). To evaluate the conditioned modulation of pain (Kg / cm2), an occlusion cuff will inflate to a painful intensity and will remain at that level in the dominant arm (as a noxious conditioning stimulus). The cuff will inflate to approximately 20 mm / Hg / s to the point where the sensation becomes painful (participants will be asked to say "stop" at this point). Then, they will adapt for 30 seconds to the stimulus and subsequently qualify their pain in an EEN. The inflation of the bracelet will increase or decrease until the participant indicates that a level of pain equal to a score of 3/10 in an EEN is reached. The UDP in the second phalanx of the left index finger is measured before the inflation of the bracelet and while the cuff is inflated and the painful stimulus is given with an intensity of 3/10. The CPM value is calculated by subtracting the first value of the second value.

Baseline, postreatment, first, second, third, fourth month and follow up sixth month.
Secondary outcome [4] 369317 0
Quality of life – Quality of life questionnaire (SF-36). Aspects like physical, emotional, social, physical and emotional interference in the patient's roles, mental and general health, corporal pain, vitality, and evolution of health will be evaluated. The final score varies from 0 to 100, being that the higher the score, the greater the state of health.

Sleep quality – The Pittsburg Sleep Quality Index (PSQI) is composed of of 24 items. The 19 self-answering questions influence the subjective estimation of sleep duration, latency and severity of sleep problems. The evaluation period comprises only the month prior to the application of the questionnaire. Seven partial components are generated (subjective quality, latency, habitual efficiency, alterations in sleep, use of hypnotic medication and repercussion on daily activities). Each one receives a score of 0 to 3. The total score is the result of adding the 7 components with what the maximum possible score is 21 points. A score equal to or less than 5 corresponds to a "good sleeper", while results greater than 5 indicate a bad sleep.

Optimism – Optimism assessment questionnaire (LOT). It is a measure of the personality disposition of optimism in the face of pessimism. It has six content elements and produces a continuous distribution of 5 points ranging from "strongly disagree" to "strongly agree". The test consists of 10 items: three affirmations about optimism, three about pessimism and four distracting items whose results are not computed The subjects respond in each statement indicating their level of agreement on a five-point Likert scale ranging from "strongly disagree" to "totally agree".

Fibromyalgia impact questionnaire (FIQ). It consists of 10 items, each with a range of 4 points (from 0, always, to 3, never). This item assesses the functional capacity of the patient through questions about activities that relate to daily life. The second and third items correspond to numerical scales that refer to days of the week. The rest of the items are valued using visual analog scales ranging from 0 to 10.

Central Awareness Inventory (CSI). Self-reported questionnaire with strong psychometric properties that is clinically very useful.. This questionnaire consists of two parts. Part A evaluates 25 health-related symptoms that are common to central sensitization with scores ranging from 0 to 100. Part B asks if you have been diagnosed with one or more specific disorders including 7 own and characteristic of central sensitization
