Introduction

Falling in the elderlyAbout 2,300 people over 65 in the UK fall every day£2.3 billion was spent on patients with a hip fracture, estimated by National Osteoporosis Society, UKPhysical degenerationAgeing balancing mechanismAge-related diseasesFear of FallingPhysical frailtyAvoidance of activities

Walking on the Pavement

Slide4

Research Objectives

To demonstrate the coping strategies used for negotiating steps on the pavementTo establish the threshold between conscious and non-conscious gait adjustmentTo understand how pedestrian environment affects walking patterns To check the protocol and feasibility of an experiment intended to inform on the above objectives

Slide5

Methods

ParticipantOne young female participant for validating the protocolApparatusEye tracker (iView X HED)Plantar insoles (F-Scan system by Tekscan, Inc.)ProcedureThe participant walked along the walkway with only one step between level and 125 mmBoth ascending and descending directions were conducted

Slide6

Methods – Experiment Set-up

Discussion

Validity of the design of the experimentFurther studiesModels of walking patterns during step negotiationGait parametersFuture experiment with older people

Slide12

Conclusion

Establish and quantify the capabilities required by the pedestrian environmentExplore how older people navigate on the pavement and what environmental cues they needImprove the pavement design to eliminate the risk as well as fear of falling
