Most serious stroke patients have the paralysis of their wrists, and can't use of their hands freely. But their wrists can be recovered by rehabilitation exercise. Recently, professional rehabilitation therapeutists exercise the wrists of stroke patients in hospital. But the wrists of stroke patients have not rehabilitated, because the therapeutists are much less than stroke patients in number. Therefore, the wrist bending-exercise rehabilitation robot that can measure the bending force of the patients' wrists is developed. In this paper, the three-axis force sensor was designed for the wrist bending-exercise rehabilitation robot. As a test results, the interference error of the three-axis force sensor was less than 0.85%. It is thought that the sensor can be used to measure the wrist bending force of the patient.

This paper describes the development of a rehabilitation robot that can provide wrist bending exercise to a severe stroke patient staying in a bed ward or at home. The developed rehabilitation robot has a three-axis force sensor which detects three directional force Fx, Fy, and Fz. The sensor measures a bending force (Fz) exerted on the wrist and the signal force (Fx and Fy) which can be used for the safety purpose. The robot was designed for severe stroke patients in bed, and the robot program was developed to perform a wrist bending rehabilitation exercise. In our tests including a nine-day experimental exercise, the developed force sensor-based robot operated effectively and safely.

Patients have the paralysis of their wrists, and can't use of their wrists freely. But their wrists can be recovered by wrist-bending rehabilitation exercise. Professional rehabilitation therapeutists exercise the wrists of patients in hospital. But the wrists of patients have not exercised enough for the rehabilitation, because the therapeutists are much less than patients in number. Therefore, the wrist rehabilitation robot should be developed, and it have to measure the applied force to the patients' wrists for their safety. In this paper, the four-axis force/moment sensor was designed for the wrist rehabilitation robot. As a test results, the interference error of the four-axis force/moment sensor was less than 0.91%. It is thought that the sensor can be used to measure the applied force to the patients' wrists.

본 연구는 한 비철금속 제조업 생산직 남성 근로자들의 인구사회학적특성, 건강관련행위 특성 및 직업관련 특성별 근골격계 자각증상호소율을 파악하고 그의 관련요인을 알아보고자 시도하였다. 조사대상은 대전광역시 소재한 비철금속 제조업체 근로자 302명을 대상으로 하였으며, 2011년 5월 1일부터 6월 30일까지의 기간 동안에 표준화된 무기명식 설문조사를 실시하였다. 연구결과, 연구대상자의 근골격계 질환 발생부위별 증상 호소율은 어깨부위의 증상이 42.7%로 가장 높았고, 다음은 허리부위 36.8%, 목 부위와 손/손목/손가락 부위가 각각 30.5%, 다리/발 부위 30.1%, 팔/팔꿈치 부위 20.9%의 순위였다. 인구사회학적 특성별 근골격계 자각증상 호소율은 연령, BMI가 낮을수록, 주관적인 건강상태가 좋지 않다는 군에서 유의하게 높았다. 건강관련 행위 특성별 자각증상 호소율은 질병으로 인한 결근한 적이 있다는 군, 외래 진료를 받은 적이 있다는 군, 입원진료를 받은적이 있다군, 규칙적인 운동이 비운동군, 수면시간이 부적당한 군에서 유의하게 높았다. 직업관련 특성별 자각증상 호소율은 업무의 신체적 부담정도가 힘들다는 군, 허리를 구부리는 작업을 하는군, 직장생활에 만족하지 않는다는 군, 근속기간이 10년 이상인 군, 허리를 구부리는 작업을 한다는 군, 반복 작업을 한다는 군에서 유의하게 높았다. 결론적으로, 생산직 남성근로자들의 근골격계 자각증상은 여러 인구사회학적 특성, 건강관련 행위특성 및 직업관련 특성과 유의한 관련성이 있었다.
