The purpose of present study was to investigate the effect of kinesio taping on pulmonary function in stroke patients using manual wheelchairs. Twenty stroke patients were divided into a wood chair group (WCG, n=10), a wheelchairs group (WG, n=10), and a kinesio taping with wheelchairs group (KWG, n=10). Taping with wheelchairs group was applied kinesio taping on back muscles (vertical paraspinal strips and oblique strips). All three groups were trained in upright seated posture for 30 minutes. Pulmonary function tests were performed with forced expiratory volume in one second, forced vital capacity and peak expiratory flow as spirometer. There was a significant increase in forced expiratory volume in one second and forced vital capacity only in KWG. The results of this study demonstrate that kinesio taping has an immediate effect on the improvement of pulmonary function in stroke patients using manual wheelchairs.

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.

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.

This paper proposes a new operation and control strategy for Power-Assisted Wheelchairs (PAW) using one brushless DC (BLDC) motor. The conventional electrical wheelchairs are too heavy and large for one person to move because they have two electric motor wheels. On the other hand, the proposed PAW system has a small volume and is easy to move due to the presence of a single wheel motor. Unlike the conventional electric wheelchairs, this structure for a PAW does not have a control joystick to reduce its weight and volume. To control the wheelchair without a joystick, a special control system and algorithm are needed for proper operation of the wheelchair. In the proposed PAW system uses only one sensor to detect the acceleration and direction of PAW's movement. By using this sensor, speed control can be achieved. With a speed control system, there are three kinds of operations that can be done on the speed of a PAW: the increment of PAW speed by summing external force, the decrement of PAW speed by subtracting external force, and emergency breaking by evaluating the time duration of external force. The validity of the proposed algorithm is verified through experimental results.

본 논문에서는 휠체어 장애인이 마트에서 손쉽게 장을 볼 수 있도록 도와줄 수 있는 자율주행 쇼핑카트 시스템의 개발 방법을 제안한다. 이 시스템은 휠체어 장애인이 직접 쇼핑카트를 끌지 않아도 휠체어 장애인의 움직임 인식하고 자동으로 따라올 수 있도록 개발되었다. 이 시스템은 휠체어 장애인의 움직임을 인식하기 위해 키넥트를 활용하며, 이를 통해 직진, 우회전, 좌회전을 판단하고, 그 결과에 따라 RC-car를 이용하여 쇼핑카트 주행을 제어한다. 이 시스템을 이용함으로써 휠체어 장애인의 쇼핑 불편함을 해소시킬 수 있을 것이다.

우리나라의 1인당 국민소득이 증가하면서 장애인의 삶의 질 향상을 위한 다양한 여가 활동에 참여가 장려되고있다. 그러나 여가활동 참여를 위해서는 여가가 행해지는 장소까지의 이동이 선행되어야 하므로, 장애인의 여가활동을 위한 이동수단에 대한 관심이 커지고 있다. 수동 및 전동 휠체어는 여가활동을 위한 이동수단으로서 각각의 단점을 가지고 있어서 수동 휠체어에 전동 휠체어의 기능을 접합하는 휠체어 동력보조 장치에 대한 관심이 높아지고있다. 본 연구에서는 휠체어 동력보조 장치 제품들의 FDA 승인 과정을 조사하고, 세계 각국에서 생산하는 측면부착형, 전방부착형, 하방부착형, 후방부착형 휠체어 동력보조 장치들의 특성을 파악하였다. 이러한 정보들은 국내 장애인 및 보조인들이 환자의 상태에 따라 최적의 제품을 선택하는데 큰 도움이 될 것이다. 장애인들이 자신에게 적합한 동력 보조 장치를 선택할 수 있도록 많은 사용적합성 시험과 임상사례 연구가 필요하다.

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.
