Manual wheelchair users are subjected to whole-body vibrations (WBV) on a regular basis as they traverse obstacles and uneven surfaces. One way users could protect themselves from secondary injuries related to WBV is by using a suspension manual wheelchair. This study investigated the ability of suspension manual wheelchairs to reduce seat accelerations during curb descents of various heights (...

Manual wheelchair (MWC) users are exposed to whole-body vibrations (WBVs) during propulsion. Vibrations enter the MWC structure through wheels’ hub, propagate according dynamical response, and finally reach user’s body by footrest, seat, backrest, handrims. Such exposure is likely be detrimental health a source of discomfort fatigue which could, in daily life, impact users’ social participation...

Physically weak, senior and disabled citizens use manual wheelchairs to move around places. The electrical wheelchairs provide them this required support for movement. It is difficult to control manual wheelchairs on sloping roads and hence the use of electrical power assisted wheelchair is advantageous, which can be controlled by braking. This paper proposes a new braking control algorithm to ...

BACKGROUND Mobility is important for the cognitive and psychosocial development of children. Almost one third of children with cerebral palsy (CP) are non-ambulant. Wheelchairs can provide independent mobility, allowing them to explore their environment. Independent mobility is vital for activity and participation and reduces the dependence on caregivers. The purpose of this study was to descri...

The proper selection of a wheelchair requires making several critical decisions, not the least of which is what type of wheelchair is appropriate. The International Organization for Standards (ISO) continues to develop and refine wheelchair standards. Standards allow the objective comparison of products from various sources, permitting consumers or clinicians to assess wheelchairs with which th...

During fiscal years 2000 and 2001, the Veterans Health Administration provided veterans with more than 131,000 wheelchairs and scooters at a cost of $109 million. This national study is the first to investigate Veterans Health Administration costs in providing wheelchairs and scooters and to compare regional prescription patterns. With a retrospective design, we used descriptive methods to anal...

An estimated 1.5 million people use manual wheelchairs in the United States [1]. Despite the frequent use of manual wheelchairs, there exists only a small, but growing literature base describing daily wheelchair usage, often in terms of daily travel distance and time spent wheeling [2-4]. While daily usage is certainly important for design and prescription of wheelchairs, it is also necessary t...

The article deals with the issues of operating wheelchairs manual drive in areas a significant inclination angle. kinematics wheelchair while climbing hill was analyzed. On basis conclusions drawn from research, two solutions for systems that block reversal on have been proposed. Among mentioned, mechanical anti-rollback system three modes and an electric is described. described part manual-ele...

2.1 Background Wheelchairs are one of the most important mobility aids for disabled patients and elders. In general, wheelchairs are categorized as manual and powered types. From the viewpoints of movement behaviours, the powered wheelchair can be regarded as a mobile robot (Asai, 2001) if additional environmental sensing components are built and an intelligent motion controller is included. Th...

the repetitious nature of propelling a wheelchair has been associated with the high incidence of injury among manual wheelchair users (mwus), mainly in the shoulder, elbow and wrist. recent literature has found a link between handrim biomechanics and risk of injury to the upper extremity. the valid measurement of three‑dimensional net joint forces and torques, however, can lead to a better unde...
