Validity of a Wearable Sensor System for Assessing Balance in High-Functioning Lower-Limb Prosthesis Users

摘要

Over half of individuals with lower-limb loss are at risk of falls and fall-related injuries (Miller, 2001) resulting from impaired gait and balance (Kamali, 2013). Common clinical measures assessing balance lack the detail and specificity to capture underlying movement factors, but innovations in wearable technology permit clinically applicable means of quantifying various balance-related performance measures. This study assessed the validity of the Mobility Lab (APDM, Portland, OR) for measuring balance in lower-limb prosthesis users (LLPUs).
