Slow-motion smartphone video improves interobserver reliability of gait assessment in ambulatory cerebral palsy.
Purpose: Structured visual gait assessment is essential for the evaluation of pediatric patients with neuromuscular conditions. The purpose of this study was to evaluate the benefit of slow-motion video recorded on a standard smartphone to augment visual gait assessment.
Methods: Coronal and sagittal plane videos of the gait of five pediatric subjects were recorded on a smartphone, including four subjects with ambulatory cerebral palsy and one subject without gait pathology. Twenty-one video scorers were recruited and randomized to evaluate slow-motion or normal-speed videos utilizing the Edinburgh Visual Gait Score. The slow-motion group (N = 11) evaluated the videos at one-eighth speed, and the normal-speed group (N = 10) evaluated the same videos at normal speed. Interrater reliabilities were determined by calculating intraclass correlation coefficients for each group as a whole, for each Edinburgh Visual Gait Score item, and after stratification by evaluator experience level.
Results: The slow-motion group exhibited an intraclass correlation coefficient of 0.65 (95% confidence interval: 0.58-0.73), whereas the normal-speed group exhibited an intraclass correlation coefficient of 0.57 (95% confidence interval: 0.49-0.65). For less-experienced scorers, intraclass correlation coefficients of 0.62 (95% confidence interval: 0.53-0.71) and 0.50 (95% confidence interval: 0.40-0.59) were calculated for slow motion and normal speed, respectively. For more-experienced scorers, intraclass correlation coefficients of 0.69 (95% confidence interval: 0.61-0.76) and 0.67 (95% confidence interval: 0.58-0.75) were calculated for slow motion and normal speed, respectively.
Conclusions: Visual gait assessment is enhanced by the use of slow-motion smartphone video, a tool widely available throughout the world with no marginal cost.
期刊介绍：
Aims & Scope
The Journal of Children’s Orthopaedics is the official journal of the European Paediatric Orthopaedic Society (EPOS) and is published by The British Editorial Society of Bone & Joint Surgery.
It provides a forum for the advancement of the knowledge and education in paediatric orthopaedics and traumatology across geographical borders. It advocates an increased worldwide involvement in preventing and treating musculoskeletal diseases in children and adolescents.
The journal publishes high quality, peer-reviewed articles that focus on clinical practice, diagnosis and treatment of disorders unique to paediatric orthopaedics, as well as on basic and applied research. It aims to help physicians stay abreast of the latest and ever-changing developments in the field of paediatric orthopaedics and traumatology.
The journal welcomes original contributions submitted exclusively for review to the journal. This continuously published online journal is fully open access and will publish one print issue each year to coincide with the EPOS Annual Congress, featuring the meeting’s abstracts.
