“…35 That may be attributable to the size and visibility of this AT, to difficulties transporting them, and to environmental accessibility issues associated with their use. 52–54 Other types of AT appeared to yield generally positive outcomes, although caregiver complaints were noted about the need to provide verbal cueing when cognitive AT was used. 32, 43 …”

Informal caregivers are a critical, yet frequently unacknowledged part of the healthcare system. It is commonly presumed that providing assistive technology (AT) will decrease the burden of their care provision; however, no review has evaluated the evidence behind this assumption. Therefore, a systematic reviews was undertaken to evaluate evidence of the impact of AT use by care-recipients on their informal caregivers. Data Sources included Embase, Medline, Cumulative Index to Nursing and Allied Health Literature, Web of Science, PsychINFO, and active researchers in this area. Twenty-two studies met the specified inclusion criteria. Collectively, the findings suggest that AT use helps caregivers by diminishing some of the physical and emotional effort entailed in supporting individuals with a disability. However, confidence in this causal connection is limited because of the relatively weak study designs that were used. This undermines our understanding of the impacts of AT use on users’ informal caregivers.

“…Energy required for the wheelchair to move is lowest on smooth, hardened surfaces, while it increases by as much as 40% on uneven hardened surfaces [10], whereas riding on a non-hardened surface, due to the high energy requirement, may prove to be impossible or even dangerous.…”

Introduction. A wheelchair is a special vehicle designed specifically for people with walking limitations. One of the types is an active wheelchair. This is a manually propelled wheelchair, the design and structure of which maximise the mobility of its given user at the expense of accepted instability. Objective. The aim of this study was to identify and present a hierarchy of potential incidents causing a health hazard and reducing the mobility of individuals with ambulatory disability who use active wheelchairs in non-urban settings. Materials and methods. Information about incidents connected with wheelchair use was collected from interviews with disabled individuals, based on a questionnaire. Recorded data were analysed using the Preliminary Hazard Analysis (PHA). Results. The results comprise a list of hazards for wheelchair user with ascribed priority numbers metrising their significance.Conclusions. An ordered list of hazards connected with wheelchair operation situations is useful when designing active wheelchairs and when learning the technique of wheelchair riding.

“…A significant correlation between right- and left-side values has been cited as rationale for not evaluating wheelchair propulsion as a bilateral task. 8,18–20 Other investigations have, however, reported side-to-side differences in power production 11,21 and stroke patterns 22 during wheelchair propulsion. We have recently measured bilateral power production across varying level and inclined terrain, and found that as the terrain became more challenging, the power produced by the dominant extremity was greater than the nondominant extremity.…”

“…Side-to-side differences between extremities have included greater power production from the dominant limb during manual wheelchair propulsion across outdoor terrain. 11 Therefore, we also hypothesized there would be significant differences between extremities for kinetic variables, with forces and moments measured for the dominant upper extremity to be significantly higher than the nondominant extremity.…”

Objective To evaluate manual wheelchair propulsion across level ground conditions that are encountered during everyday life. Design Subjects included 14 individuals (13 with spinal cord injury [SCI], 1 with spina bifida) who were experienced manual wheelchair users and had no current upper extremity injury or pain complaints. Subjects propelled their wheelchairs at a self-selected speed across four different level ground conditions, including smooth and aggregate concrete and tile and carpet flooring. Temporal and kinetic measurements were obtained bilaterally from instrumented wheelchair rims during the steady-state phase of propulsion. Results There were no side-to-side differences for any of the temporal or kinetic variables. Propulsion velocity and pushrim contact time were consistent across ground conditions. Propulsion frequency was significantly greater during both concrete conditions than either tile or carpet ground conditions. Forces and moments were greatest during the aggregate concrete ground condition and lowest during propulsion across tile flooring. Conclusions The rolling resistance of level surface terrain significantly impacts wheelchair propulsion biomechanics. Identification of environmental conditions that may contribute to upper extremity pathology is a step toward injury prevention and maintenance of functional abilities for the manual wheelchair user. These results may be used to assist with home and community terrain design to minimize the demands associated with wheelchair propulsion.
