The objective of this study was to determine how simulated manual wheelchair pushing influences biomechanical loading to the lumbar spine and shoulders. Sixty-two subjects performed simulated wheelchair pushing and turning in a laboratory. An electromyography-assisted biomechanical model was used to estimate spinal loads. Moments at the shoulder joint, external hand forces and net turning torqu...

An understanding of adverse incidents and injuries sustained by active wheelchair riders, who live and work in the mainstream of society, is needed to improve safety via wheelchair design, selection, and configuration. We interviewed 109 riders who had experienced incidents, in order to identify the causes of incidents and injuries they suffered. Participants reported n = 253 incidents (53% in ...

Some people without independent mobility are candidates for powered mobility but are unable to use a traditional power wheelchair joystick. This proof-of-concept study tested and further developed an innovative method of driving power wheelchairs for people whose impairments prevent them from operating commercial wheelchair controls. Our concept, Self-referenced Personal Orthotic Omni-purpose C...

In this paper, a study on sonification of manual wheelchair movements is presented. The aim was to contribute to both rehabilitation contexts and in wheelchair sports contexts, by providing meaningful auditory feedback for training of manual wheelchair operation. A mapping approach was used where key parameters of manual wheelchair maneuvering were directly mapped to different sound models. The...

OBJECTIVES To test the hypothesis that powered wheelchair users who receive the Wheelchair Skills Training Program (WSTP) improve their wheelchair skills in comparison with a control group that receives standard care, and secondarily to assess goal achievement, satisfaction with training, retention, injury rate, confidence with wheelchair use, and participation. DESIGN Randomized controlled t...

OBJECTIVE To determine the best test performance and feasibility using a Graded Arm Cranking Test vs a Graded Wheelchair Propulsion Test in young people with spina bifida who use a wheelchair, and to determine the reliability of the best test. DESIGN Validity and reliability study. SUBJECTS Young people with spina bifida who use a wheelchair. METHODS Physiological responses were measured ...

In this paper, to analyze the transport of autonomous robots, an artificial Capital market is used. Capital market is considered as a pier which loading and unloading of cargo is done. Autonomous robots load and unload from the ship to the warehouse wharf or vice versa. All the robots have the ability of transporting the loads, but depending on loads and the location of unloading (or loading) a...

This poster presents results obtained from experiments of driving a brain-actuated simulated wheelchair that incorporates the shared-control intelligence method. The simulated wheelchair is controlled offline using band power features. The task is to drive the wheelchair along a corridor avoiding two obstacles. We have analyzed data from 4 naïve subjects during 25 sessions carried out in two da...

Self-checkout is the emergent/emerging retail technology wherein users (shoppers) check out their own items using an interactive kiosk. A dramatic growth is anticipated in the prevalence of self-checkout systems in retail environments. A study was conducted to develop and evaluate a redesign of a self-checkout system with a focus on issues related to physical accessibility for wheelchair users....

encouraging an active lifestyle is an essential part of successful rehabilitation programs, and the link between physical activity and quality of life (qol) is well established among patients with mobility disorders. biomechanical aspects of wheelchair design play an important role in physical activity and social participation of disabled individuals. this review focuses on key biomechanical fe...
