AUTOMOBILE VEHICLE INGRESS/EGRESS MOVEMENT STRATEGIES ADOPTED BY ELDERLY AND/OR, HIP OR KNEE, PROSTHESIS HAVING PERSONS

This paper presents the automobile ingress/egress movement strategies adopted by 41 test subjects from a mixed population of able-bodied, elderly and/or disabled drivers when entering/exiting four stripped vehicles representing 90% of the automobile types presently on the market. Two general movement families were identified, those starting from a standing position on one foot or on two feet. Eight ingress/egress movement strategies were identified (5 ingress and 3 egress). This paper describes these strategies in terms of the population performing them and the vehicle tested. It appears that no one strategy is used systematically by a single person, since subjects tend to adapt their strategy to the tested vehicle.
