Most physical interventions for musculoskeletal pain in children and adolescents cannot be reproduced in clinical practice: a meta-research study of randomized clinical trials

Conservative treatments such as physical therapies are usually the most indicated for the management of musculoskeletal pain; therefore, a detailed description of interventions enables the reproducibility of interventions in clinical practice and future research. The objective of this study is to evaluate the description of physical interventions for musculoskeletal pain in children and adolescents. We considered randomized controlled trials that included children and adolescents between 4 and 19 years old with acute or chronic/persistent musculoskeletal pain. We included physical therapies related to all types of physical modalities aimed at reducing the intensity of pain or disability in children and adolescents with musculoskeletal pain. The description of interventions was assessed using the Template for Intervention Description and Replication (TIDieR) checklist. We performed electronic searches in the following databases: CENTRAL, MEDLINE, EMBASE, CINAHL, PsyINFO and PEDro up to April 2024. The description of physical interventions was presented using frequencies, percentages and 95% confidence intervals (CIs) of the TIDieR checklist items described in each study. We also calculated the total TIDieR score for each study and presented these data as mean and standard deviation. We included 17 randomized controlled trials. The description measured through the TIDieR checklist scored an average of 11 (5.2) points out of 24. The item of the TIDieR that was most described was item 1 (brief name) and most absent was item 10 (modifications). The descriptions of physical interventions for the treatment of musculoskeletal pain in children and adolescents are partially described, indicating the need for strategies to improve the quality of description to enable true clinical reproducibility.
