Feasibility of wearable technology for ‘real-world’ gait analysis in children with Prader–Willi and Angelman syndromes

Abstract

Abstract. Background: Prader–Willi syndrome (PWS) and Angelman syndrome (AS) are neurodevelopmental disorders in need of innovative ‘real-world’ outcome measures to evaluate treatment effects. Instrumented gait analysis (IGA) using wearable technology offers a potentially feasible solution to measure “real-world’ neurological and motor dysfunction in these groups. Methods: Children (50% female; 6–16 years) diagnosed with PWS (n = 9) and AS (n = 5) completed ‘real-world’ IGA assessments using the Physilog®5 wearable. PWS participants completed a laboratory assessment and a ‘real-world’ long walk. The AS group completed ‘real-world’ caregiver-assisted assessments. Mean and variability results ..
