As many different healthcare professionals are involved in the diagnosis and treatment of musculoskeletal disorders, the Special Issue published high-quality studies from different areas of healthcare. Studies reporting on original research (e.g., randomized controlled trials, cohort studies), but also systematic literature reviews and meta-analyses within the scope of the Special Issue were considered.
