One hundred and three experienced users of powered vehicles were invited to Banstead Mobility Centre on two separate days, to try a range of vehicles. Twenty five vehicles were included in the study, demonstrating the wide variety of features in design of electric wheelchairs, three-wheeled scooters and four-wheeled buggies. Each user was classified according to age, disability group and sex. The presence of pain, muscle weakness, joint restrictions was noted and anthropometric measurements were recorded, together with other relevant attributes. On average each user tested nine vehicles over the two days. The users' subjective views, together with objective scores obtained during set indoor and outdoor tests, were recorded. This data was analysed in relation to the users' abilities and difficulties. It was confirmed that some features of design are helpful to some disabled and elderly users whilst other features make vehicles uncomfortable and more difficult for many users.
