Abstract Summary
Rollators are frequently prescribed for older persons suffering from gait and balance disorders in order to improve mobility and quality of life. Rollators are designed to decrease the risk of falls by improving gait mechanics of their users. However, data on the biomechanics of rollator assisted gait are scarce and mostly derived from experiments with younger adults. Therefore, this study aims to compare lower limb joint angle kinematics during level walking of geriatric inpatients with rollator and healthy older persons without rollator. Statistical parametric mapping was used to compare joint angle waveforms. Significant differences between groups were observed in the joint angles of the sagittal plane. The investigation of joint kinematics may reveal important clinical findings about gait mechanics, balance and mobility of old persons who are dependent on a rollator.
