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
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

Analysis and Preliminary Results

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
