Usefulness of digital measurements for functional evaluation of paediatric elbow range of motion

Abstract

Background Elbow immobilization due to fractures of the upper limb is frequent in paediatric patients. Proper follow-up is critical to assess elbow functional recovery. Telemedicine can be an option for remote monitoring of these patients. The purpose of this study was to compare personal and virtual evaluation of elbow range of motion after long arm cast withdrawal in paediatric patients. Methods An observational cross-sectional study was carried out which included all paediatric patients with elbow immobilization in long arm casts treated at our centre. After cast withdrawal, elbow range of motion was evaluated by telemedicine and in office consultation in all four movements (flexion, extension, pronation and supination). Results Ninety-three patients met the selection criteria. Median age at time of immobilization was 8 years. Mean elbow immobilization time was 23 days (range 18–56 days). When comparing office and remote measurements, no statistical differences were found for any of the four elbow movements measured in our study. Conclusions Remote evaluation of elbow range of motion by telemedicine is technically feasible. We evaluated elbow range of motion in paediatric patients after immobilization and we did not find differences between digital and in office measurements. The results were similar to those obtained through assessment in the office. We believe that this is a useful tool to facilitate remote patient follow-up.
