Summary of results from the quantitative analyses regarding performance of physical activities (eight studies with n=1267 participants reporting on short-term and long-term effects combined). Number of studies and participants, (pooled) effect sizes and, if applicable, I2 statistics (depicting heterogeneity) are shown. Short-term and long-term effects are presented. Total results as well as results stratified by intervention component (active referral, e/mHealth and multicomponent interventions with a combination of elements) and patient category (back, knee, hip and upper extremity surgery) are shown.
