Systematic evaluation of the guidelines for rehabilitation in multiple sclerosis patients: an overview according to ICF functioning domains.

High-quality clinical practice guidelines (CPGs) can provide evidence-based recommendations for optimizing care on managing multiple sclerosis (MS). There is currently no review that compiles recommendations of high-quality CPGs to guide decision-making for MS rehabilitation. The aim was to identify evidence-based recommendations in high-quality multidisciplinary English CPGs for rehabilitation in MS. CPGs published in the last 10 years (2009-2019) that described recommendations on rehabilitation were searched in PubMed, Turning Research into Practice database, International Guideline databases, National Guideline databases and websites of MS organizations. Quality assessment of CPGs was conducted by two evaluators using the Appraisal of Guidelines for Research and Evaluation II instrument. Recommendations were classified according to the International Classification of Functioning, Disability and Health (ICF) and the International Classification of Health Intervention (ICHI) and documented in terms of strength of recommendation and level of evidence. Five CPGs satisfied the inclusion criteria. Of 120 recommendations, 38 had a strong level with moderate to low level of evidence, 61 were of weak strength and 18 were formulated by the consensus of experts. Recommendations were categorized into 12 domains and 1 chapter on the body function level, 1 chapter on activity level and 2 domains on external factors. The existing CPGs demonstrated more than 100 evidence level recommendations to be followed at the clinical practice, most in body functions of the ICF. Developing up-to-date CPGs with more focus on activity and participation domains for countries with various healthcare backgrounds may be useful for a best clinical practice.
