Biomechanical Analysis of the Walking Pattern in Healthy Subjects with and without Rollator

INTRODUCTION The rollator is a commonly used walking-aid in elderly and in disabled subjects. The purpose of using the rollator is to improve the walking performance and minimize the risk of falling. Studies have shown that the walking performance in elderly subjects measured as distance, cadence and velocity is improved when they walk with a rollator [1]. However, knowledge about the specific changes in the joint moment patterns of the ankle, knee and hip joint are limited. Thus, the purpose of the present study was to investigate the biomechanical effects of walking with a rollator on the walking pattern in healthy subjects.
