The objective of this study was to determine the effectiveness of biopsychosocial rehabilitation for upper-limb repetitive-strain injuries among working-age adults. Studies were identified from electronic bibliographic databases, reference checks, and consultations with experts in rehabilitation. Four blinded reviewers selected randomized controlled and controlled trials. Two experts evaluated the clinical relevance of the findings. Two other reviewers extracted the data and assessed the main results and the methodological quality of the studies. Finally, a qualitative analysis was performed. Only 2 studies satisfied the criteria. They were both considered to be low-quality trials. The clinical relevance of the included studies was also unsatisfactory. The level of scientific evidence was limited, showing that hypnosis as a supplement to comprehensive treatment can decrease the pain intensity of acute repetitive-strain injury in short follow-ups. There appears to be little scientific evidence for the effectiveness of biopsychosocial rehabilitation with respect to repetitive-strain injuries.
