Background:
Although increasing participation in physical activities has significant health benefits, there are no guidelines to help professionals decide when it is safe to return to activity after injury.
Objective:
To examine the specific criteria (eg, strength, pain) that expert sport medicine clinicians use for return to activity decisions in children with musculoskeletal injuries.
Methods:
The authors conducted an online cross-sectional survey of certified Canadian sport medicine doctors (MDs) and sport rehabilitation specialists (physiotherapists (PTs) or athletic therapists (ATs)). The authors asked how they would measure each of the following signs in the context of a knee injury: sport-specific skills, pain, swelling, strength, range of motion (ROM) and balance. Clinicians also ranked the importance of each sign with respect to influencing their recommendations for each of five clinical vignettes.
Results:
The overall response rate was 33.6% (464/1380) with similar rates for each profession. For each clinical sign, all three professions preferred the same measure to determine readiness to return to play: standardised testing for sport-specific skills, impact on function for pain, palpation for swelling, manual muscle testing for strength, visual inspection for ROM and standing on one leg with eyes closed for balance. Regarding importance of specific signs for return to activity, all professions had similar responses for one vignette, but MDs differed from PTs and ATs for the remaining four. Finally, pain was ranked as the no 1 or 2 most important sign in all five vignettes by 41.0% of MDs, 18.1% of ATs and 11.3% of PTs, whereas sport-specific skills was chosen by 9.6% MDs, 12.0% ATs and 16.1% PTs.
Conclusion:
Our results provide the foundation for future work leading towards the development of interdisciplinary consensus guidelines.

01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...

Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
