“…One subcomponent of the FMV, the caster, has received substantial attention [18] but only in respect of shimmy, which occurs at higher velocities than would arise with an FMV carrying a large, heavy load while manoeuvred in a confined space. Additionally, some empirical studies of caster wheel motion resistance either in isolation [10,18,19] or as part of a fixed wheel vehicle [20][21][22][23] have been made. Exceptionally, one study included forward FMV motion [10], but none has considered motion resistance during general FMV motion.…”

Motion resistance, handle forces, and translational acceleration of a four-caster manually manoeuvred vehicle (FMV) are examined at impending planar motion.FMV-wheel angular acceleration directions occur in polygon regions of the FMV-body translational acceleration. The mass centre force and torque, which balance motion resistance, using a Coulomb model, are non-linear and discontinuous functions of FMV-body acceleration.The transformation from mass centre force and torque to a dynamically equivalent handleforce measure is examined. A reference manoeuvre with a single set of caster orientations shows that FMV-body translational acceleration has a substantial effect on handle-force measure variation: an almost three-fold variation exists.The reference manoeuvre analysis is repeated with a representative sample of all caster orientations. The mean handle-force measure for this sample also shows a substantial handle-force measure variation, e.g. relatively high handle forces occur when the translational acceleration is directed as the impending change of FMV heading. This effect is independent of motion resistance values. As the handle forces required to balance motion resistance vary substantially depending on FMV-body translational acceleration, spatial constraints may have a substantial effect on handle forces. A relationship between handle forces and spatial constraints indicates that architectural planning has health and safety implications for the FMV operator.

While there were a fair number of articles (n = 41) documenting accessible design features of pedestrian infrastructures, the quality of the evidence was low. The review identified knowledge gaps. Although specific design solutions exist, they have not yet been tested among individuals with various or multiple types of physical disabilities to ensure access to pedestrian infrastructures by all. Implications for Rehabilitation Pedestrian infrastructures still pose problems to mobility, limiting social participation and quality of life outcomes for individuals with physical disabilities (motor, visual and hearing). The results of this mapping review show that few articles are concerned with the accessibility of pedestrian infrastructures for more than one type physical disability, which might lead to recommendations that are inadequate for individuals with differing disabilities, few recommendations have been compared, most studies have been performed in environments not representative of northern countries and their quality score was generally low. Health professionals and State Parties have a complementary expertise that should be put to use in the determination and implementation of best design solutions to ensure the respect of the needs of individuals with physical disabilities. This review can thus help them have an idea of what has already been done to identify what needs to be achieved to fill the gap of knowledge required to insure access for individuals with motor, visual as well as hearing disabilities. Rehabilitation profesionals should take part in the assessment of the proposed solutions as well as the development of new designs to fill knowledge gaps.
