Here is the design of a clinical trial:

Official Title: Fibromyalgia and Specific Physical Activity

Included conditions:
- Fibromyalgia

Study Armgroups:
- {'label': 'Specific Physical Activity', 'type': 'EXPERIMENTAL', 'description': 'Specific patient care in telephone coaching of fibromyalgia patients.', 'interventionNames': ['Other: Specific Physical Activity']}
- {'label': 'Classic Physical Activity', 'type': 'OTHER', 'description': 'Classic patient care in common group of multipathological patients.', 'interventionNames': ['Behavioral: Classic Physical Activity']}

Interventions:
- {'type': 'OTHER', 'name': 'Specific Physical Activity', 'description': 'An individual one hour face-to-face session conducted by adaptated physical activities teachers followed by eight telephone sessions by physical therapists and adaptated physical activities teachers (4 sessions each)', 'armGroupLabels': ['Specific Physical Activity']}
- {'type': 'BEHAVIORAL', 'name': 'Classic Physical Activity', 'description': 'One session per week in groups conducted by adaptated physical activities teachers of "Siel Bleu" association', 'armGroupLabels': ['Classic Physical Activity']}

Primary Outcomes:
- {'measure': "Compare the Interest of a Specific Physical Activity Program on Patients' Quality of Life", 'description': 'Evolution of the Fibromyalgia Impact Questionnaire (FIQ) score (questionnaire of specific quality of life in the management of fibromyalgia patients) between the beginning of care (J0) and six months (M6).\n\nThe scale score ranges from 0 to 100. The higher the score, the greater the difficulty in functioning and the severity of symptoms.', 'timeFrame': '6 months after randomization'}

Please estimate the sample size based on the assumption: 
Power of 0.80, alpha risk of 0.05, and a 10% increase to account for potential dropouts.
Sample size {14}
        The study by Hackshaw et al. [14] used inclusion criteria that were similar to those of the present study; the mean FIQR at baseline for the 10 patients included was 49.4âÂ±â13.8 (meanâ+âSD). We consider that a 7-point difference between the two treatment arms at 6âmonths would be clinically significant. The sample size required to show a between-group difference of 7 points in the FIQR with a power of 0.80 and an alpha risk of 0.05 is 114 patients. In order to ensure this power is achieved, 10% more patients will be included, thus a total of 126 patients.
