Abstract

PURPOSE: To investigate the reliability of a 3D-accelerometry based gait analysis, and its correlates with clinical status and fall-risk. METHODS: Forty elderly subjects presenting with increased fall-risk (OFR), 41 elderly controls (OC) and 40 young controls (aged 80.6±5.4, 79.1±4.9 and 21.6±1.4 years respectively) underwent three gait evaluations (two assessors in random order) each containing two walks of 18m with a DynaPort MiniMod accelerometer on the pelvis. Intra- and inter-observer reliability of gait speed, step-time asymmetry, mediolateral and craniocaudal step and stride regularity were determined by ICC and CV of standard error of measurement (CV(SEM)). Relationships with cognition (MMSE), dependency, grip strength, muscle endurance, and fall-risk (fall-history, timed-get-up-and-go and Tinetti-test) were analysed in elderly participants. RESULTS: Reliability for single walk was low (ICC<0.70, 11%0.80, CV(SEM)<7%), but high (ICC>0.70, 4%
