Objective: This study was conducted for one-hand users including hemiplegic clients currently using general folding manual wheelchairs, so as to analyze their specific problems and recommend solutions regarding usage. Background: Traditional manual wheelchairs require considerable use and control of both hands for operation, thus adaptations become necessary for individuals with asymmetrical use of hands. Method: Thirty hemiplegic clients who were admitted to rehabilitation and convalescent hospitals participated as subjects. The research tools were general folding manual wheelchairs commonly used by people with impaired gait, and the Wheelchair Skills Tests (WST) WST-M/WCU 4.1 version was adopted as the assessment tool. All participants were asked to fill out questionnaires on demographics and wheelchair usage characteristics. Assessment procedures were performed with currently used manual wheelchairs and with/without the use of foot to control the wheelchair. Results: When the participants drove folding manual wheelchairs without the use of foot, even the lowest failure rate among the WST items tested recorded 96.7%. On the contrary, with the use of foot in maneuvering the wheelchairs, failure rates dropped noticeably and success rate among the WST items tested was as high as 86.7%. Conclusion: These findings imply that the use of one-arm (hand) propellable (drivable) wheelchair can be an active and effective solution in resolving problems for hemiplegic clients using existing manual wheelchairs. As such, the government should provide institutional support to further develop and distribute this device or technology, and promote relative research in tandem. For now, the supply of commercially available device to hemiplegic clients is deemed urgent and also a mechanism to provide the devices and relevant services. Application: This study offers viable solutions for hemiplegic clients who rely on existing manual wheelchairs to increase their mobility and occupational performance.

In this paper, we applied composite material of high specific stiffness and strength to the fabrication of a folding wheelchair frame for the replacement of conventional metal wheelchair frames. A one-body composite frame was designed and the finite element analysis was performed on this design. Some specimens of joint parts were manufactured and strength test was done. With the results of analysis and test, some modification was done and a prototype was produced.

Although there existed many types of manual/power hybrid wheelchairs, their use was not widespread because of their inconvenience in converting drive system and in folding frames. To carry a wheelchair in the car or to convert driving methods, some hard work of disassembling or exchanging wheels was required for most of currently available hybrid wheelchairs. In this study, the standard foldable manual wheelchair was reformed to a power wheelchair by installing the newly developed Axial Flux Permanent Magnet(AFPM) type of brush less direct current(BLDC) motor on each rear hub of wheelchair. This wheelchair could be driven by manual or electric power without exchanging. wheels, thus no additional work was needed for carriage or for power conversion. The developed wheelchair was evaluated for durability, stability, maneuverability, cost, and reliability in accordance with the Korean standards. The results indicated that the developed hybrid wheelchair was good enough for commercialization comparing to other imported wheelchairs.

The main concepts in the design and construction of an motorized wheelchair for loading in the car which is intended to drive a disabled to long distance. The wheelchair is basically a powered and folding, so it is designed to motorized manual wheelchair by modularity method. The wheelchair has been installed with a power motor module, battery module, and drive & control module. The goal of this project is to develop a wheelchair that has multifunction and operated disabled who has variety impairment. So we are currently working.

본 논문은 전동휠체어를 사용하는 장애인을 관리하고 보조하는 간병인을 대상으로 전동휠체어의 만족도에 대한 것이다. 전동휠체어 만족에 대한 설문은 일상생활에서 가장 많이 사용하는 항목들을 전문가 의견과 간병인들의 의견을 통해 안정성, 조작성, 만족도 항목의 사용성 공통 항목들을 선택하였다. 또한 간병인의 일반적 특성, 간병 경력, 간병시간, 간병의 어려움과 전동휠체어 무게의 문제점을 개선하기 위해 접이식 전동휠체어 개발에 대한 의견도 조사하였다. 대상자는 전동휠체어를 사용하는 장애인을 보조하는 간병인 50명이었다. 연령대는 평균 54.54세이었고, 간병 경험은 80.98개월이었고, 하루 간병 평균시간은 9.80시간이었다. 전동휠체어 사용에 대한 만족도는 안전성, 조작성, 항목에서는 대부분 만족하였으나, 무게와 세척에 대한 만족도 항목에서 만족도가 떨어지는 것을 알 수 있었다. 전동휠체어의 가장 큰 문제점은 무게가 무겁고 조작하기 힘들고, 간병인들을 옮기기가 힘들다는 의견이 가장 많았으며. 접이식 전동휠체어에 대한 선호도는 높은 것으로 조사되었다. 간병인들은 전동휠체어 사용만족도 조사에서 무게가 가볍고, 보관 및 세척이 편리한 전동휠체어 개발의 필요성을 강조하였다. 따라서 이를 관리하고 보조하는 간병인들의 특성을 반영한 접이식 전동휠체어 개발이 필요하다.

The purpose of this study was to compare government guidelines and foreign guidelines related to furniture design for elderly. Future elderly will increasingly accustomed to the provisions of improved housing, education and welfare in comparison with our forebears. Also, there will be upgrading and different need for elderly furniture in our market. The results were as follows. The height of bed was based on the height of wheelchair seat, commonly. A adjustable bed was recommended for abled and disabled elderly. A pull-down shelf, drawer, empty space under chest, folding or sliding door in wardrobe and so on were recommended as a elderly furniture. It were good adjustable sink on human scale. There were need the empty space under sink for wheelchair users, one-touch or lever faucet, etc. There have given a little furniture design guidelines for elderly in Korea until now. But those guidelines haven't been considered enough human scale of elderly including wheelchair user. Because the close investigations have not made about abled and disabled elderly for their furniture design. So first of all, the government should be examined elderly physical size more accurately for elderly furniture design. The guideline for elderly furniture design should be for abled elderly and the disabled, too.
