Fall prevention walker during rehabilitation
2017
This paper proposes on the design of a walker for the prevention of falling among elderlies or patients during
rehabilitation whenever they use a walker to assist them. Fall happens due to impaired balance or gait problem. The
assistive device is designed by applying stability concept and an accelerometric fall detection system is included. The
accelerometric fall detection system acts as an alerting device that acquires body accelerometric data and detect fall.
Recorded accelerometric data could be useful for further assessment. Structural strength of the walker was verified via
iterations of simulation using finite element analysis, before being fabricated. Experiments were conducted to identify the
fall patterns using accelerometric data. The design process and detection of fall pattern demonstrates the design of a
walker that could support the user without fail and alerts the helper, thus salvaging the users from injuries due to fall and
unattended situation.
