The Telemedicine-Based Pediatric Examination of the Back and Lower Limbs: A Narrative Review

The COVID-19 pandemic has accelerated the transition to virtual healthcare while also prompting an abundance of new literature highlighting telemedicine's capabilities and limitations for various medical applications, notably musculoskeletal examinations. Telemedicine provides an opportunity to deliver timely patient- and family-centred care while maintaining physical distancing and improving access to remote communities. This review aims to narrate the current state of the literature on telemedicine applied in the context of a musculoskeletal examination for children aged 3 to 18 years. The PubMed and ScienceDirect databases were searched for relevant articles from January 2015 to August 2021 using a combination of keywords and nested searches. The general examination components relevant to the back and lumbosacral spine, hip, knee, ankle/foot, and gait are described. These components include inspection, palpation, range of motion, motor, and sensory examination as well as special testing. There is general feasibility, validity, and substantial reliability in performing most examination components, and primary diagnoses established virtually were found to be either the same or similar in the vast majority of cases. Despite the current literature focusing mainly on adult populations, we describe how each aspect of the exam can be reliably incorporated into a virtual appointment specific to the pediatric population. Currently available smartphone-based applications that measure joint range of motion were generally found to have high reliability and validity. Caregivers are needed for most of the consultation, especially in younger children, but select physical exam maneuvers can be self-performed by older children and adolescents alone. By providing an overview of the available smartphone tools as well as the reliability and validity of remote assessments, this review not only establishes a foundation for a structured pediatric musculoskeletal examination, but also aims to increase providers' confidence in incorporating telemedicine into their practice.
