One of the basic problems of user on manual wheelchair is overcoming architectural barriers (kerbs, stairs etc.) on its way. Even though many research studies have been reported in different fields to increase the independence of wheelchair users, the question of overcoming obstacles by a wheelchair always remains as topic of discussion for many researchers. In this paper, the author has propos...

This study investigates the load sharing capabilities for half-caps of a 190m long timber bridge. The bridge has 31 spans over the Avon River in Toodyay, Western Australia. It was constructed from local hardwood timbers and had a series of repairs. However as the width between kerbs was only 5.5 m and it was no footpath it was decided to replace the bridge by a new wider concrete structure. The...

OBJECTIVE To describe and compare the content, feasibility, outcome parameters, and clinimetric properties of the manual wheelchair skills tests reported in the literature. DESIGN A systematic literature search was conducted in MEDLINE, EMBASE, PsychINFO and Current Contents.

Terrestrial Laser Scanner (TLS) have seen increasing use in survey practices as a means of fast capturing large volumes of point data, with one such practice being the surveying of as-built features for roads. This paper presents methods to automate some of the processing of road scenes. The method focuses primarily on the automation of the identification and extraction process of kerbs and sur...

This paper proposes a new method to analyze human walking by using a 3-wheels rollator walker instrumented with encoders and a 3D accelerometer/gyrometer. In order to develop walking quality index and monitor the health state of elderly people at home, the walking of 23 young adults and 25 elderly people (> 69 years) with the help of the walker, are compared. The results show that many general ...

BACKGROUND Descending kerbs during locomotion involves the regulation of appropriate foot placement before the kerb-edge and foot clearance over it. It also involves the modulation of gait output to ensure the body-mass is safely and smoothly lowered to the new level. Previous research has shown that vision is used in such adaptive gait tasks for feedforward planning, with vision from the lower...

Ninety-five patients with rheumatoid arthritis or osteoarthrosis were interviewed and questioned in their homes, being randomly selected from 354 outpatients with these diseases. The findings were compared with answers from 30 matched able-bodied controls. The handicapped were mainly female and elderly; over half were severely or appreciably handicapped; nearly one-third lived alone. The averag...
