High-Technology Based Gait Assessment in Frail People: Associations between Spatio-Temporal and Three-Dimensional Gait Characteristics with Frailty Status across Four Different Frailty Measures.
J Nutr Health Aging. 2017; 21(3):346-353.JN

Abstract

OBJECTIVE

We analyzed associations between a battery of gait characteristics and frailty status across four different frailty instruments in old patients.

DESIGN

Cross-sectional study.

SETTING

Geriatric wards of a general hospital.

PARTICIPANTS

123 hospitalized patients aged ≥65 years.

MEASUREMENTS

Spatio-temporal and three-dimensional gait characteristics were assessed by an electronic walkway and a shoe-mounted, inertial sensor-based mobile gait analysis system. Frailty status was assessed by the frailty phenotype (FP), Clinical Frailty Scale (CFS), frailty index (FI), and frailty index based on a comprehensive geriatric assessment (FI-CGA).

RESULTS

A reduction in walking speed (FP, FI, FI-CGA), stride length (FP, FI, FI-CGA), maximum toe clearance (FP, CFS, FI, FI-CGA), toe off angle (FP, CFS, FI, FI-CGA), heal strike angle (FI-CGA) and greater stride length variability (FP, CFS, FI, FI-CGA), stride time variability (FP, FI), double support time (FP, FI), and stride width (CFA, FI-CGA) were associated with frailty status across the four frailty instruments (all P < 0.05, respectively). Walking speed (FP, CFS, FI, FI-CGA), stride length (FP, CFS, FI, FI-CGA), maximum toe clearance (FP, CFS, FI, FI-CGA), toe off angle (FP, CFS, FI, FI-CGA), heal strike angle (FP, FI), stride length variability (CFS, FI, FI-CGA), stride time variability (FI), double support time (FP), and stride width (FP, CFS, FI) were related with frailty severity across the four frailty instruments independent of age and sex (all P adjusted < 0.05, respectively).

CONCLUSIONS

Gait changes in frail patients include more than solely a reduction in walking speed.
