Abstract:
Full time wheelchair users are at a height disadvantage during many function activities, such as transferring or reaching. Retrieving objects from the ground or a higher shelf while seated in the wheelchair can be both difficult and unsafe. Lateral transfers between surfaces at different heights can be difficult and unsafe. Sit-to-stand transfers are made simpler with a higher seat. This research project seeks to assist reach and transfers by designing a system to raise and lower a wheelchair seat over a 4'' range. The project included several needs assessment: 1) by conducting interviews and

碩士<br>南開科技大學<br>福祉科技與服務管理所<br>97<br>This project developed a omni-directional motion wheelchair. For the senior people and handicap person, we will provide a very smoothly omni-directional motion wheel chair. It will continue to use the existing manual and electrically operated wheel chair merit, and innovate to a novel omni-directional wheelchair system. Enable the dexterous electrically operated wheelchair along each free position direct migration, but overcomes the existing wheelchair to need the complicated mode of motion. Founds the electrically operated wheelchair nimble movement ability

Therefore, the purpose of this work is to design a creative wheelchair by using creative methodology. First, we analyze the specifications of wheelchairs. And, based on the concepts ofgreen products and modularized design, we design a modularized wheelchair by usingthe TRIZ method. The designed wheelchair is composed of modular and normalizedelements such as the user can easily alloca

Abstract:
The manual wheelchair (MWC) and power wheelchair (PWC) each present advantages and disadvantages to participation and occupational performance. Consequently, some individuals choose to use both devices, depending upon the activity. A pushrim-activated, power-assisted wheelchair (PPW) may provide an alternative to the PWC for these users. This study utilized a two-phase, mixed methods design, comparing the performance and satisfaction of wheelchair users carrying out self-selected activities with their current PWC and with a PPW. There was no statistically significant difference in outcome meas

Abstract:
Manual wheelchair users who live in cold climates are faced with daily difficulties related to personal independence and societal inclusion, as their assistive devices are unable to overcome the physical barriers created by snow. Packed snow on sidewalks creates a barrier for wheelchair users as the small caster wheels become embedded in the snow-pack, this leads to upper body fatigue as well as wheelchair tipping, and falling. The purpose of this thesis was to develop a method by which the best design could be determined of a group of four commercially available manual wheelchair casters. Thi
