Abstract
    Objective. – The development of a rigorous methodology based on published results of clinical trials, evaluation of daily practice in France
and multidisciplinary expert opinion to elaborate recommendations for rehabilitation interventions.
    Methods and results. – The following describes the methodology of SOFMER (Société Française de Médecine Physique et de Réadaptation
[French Society of Physical Medicine and Rehabilitation]) for developing recommendations for rehabilitation interventions. The test case was
developing recommendations for rehabilitation in hip or knee osteoarthritis (OA) and hip or knee arthroplasty. Physicians in rehabilitation,
orthopedic surgery and rheumatology identified, synthesized, and analyzed data from the literature by use of the usual French system of grading
trials (the French Agency for Accreditation and Evaluation in Healthcare [ANAES] scale). The data were published results of comparative
controlled studies such as randomized controlled trials, controlled clinical trials, cohort studies, case control studies, reviews of clinical trials,
and case series, as well as uncontrolled cohort studies. The resulting recommendations were presented to the three annual French national con-
gresses of rehabilitation, rheumatology, and orthopedic surgery for comment and for adapting to French professional practice. Finally, a panel of
multidisciplinary experts (physicians in physical medicine and rehabilitation, rheumatologists, orthopedic surgeons, general practitioners, physical
therapists, social workers, podologists, occupational therapists, nurses, and patients) validated the recommendations.
    Conclusion. – The SOFMER methodology could be an interesting tool for use in developing recommendations elaborated by all the con-
cerned medical and surgical specialists in the wide domain of rehabilitation.
