근골격계 질환 환자들은 정상인들에 비해 질환 부위의 관절 가동 범위(ROM, Range of Motion)가 제한되는 경향이 있다. 이러한 근골격계 질환 환자들의 관절 가동 범위 제한을 고려하지 않은 재활 운동 콘텐츠 서비스는 오히려 환자의 건강 상태를 악화시킬 수도 있으므로 주의해야 하는 서비스 요인이다. 본 논문에서는 근골격계 질환 환자의 제한적인 관절 가동 범위를 고려한 아바타 기반의 재활 운동 콘텐츠 서비스 기술을 제안한다. 이에 재활 운동의 모션 캡처 데이터로부터 아바타 재활 운동 콘텐츠로의 변환 기술과 근골격계 질환 환자의 관절 가동 범위 제한 정보를 적용한 아바타 기반 재활 운동 콘텐츠 재현 기술을 설계한다. 일련의 기술적 구성 요소를 고찰하고 설계함으로써 근골격계 질환 환자들의 서로 다른 관절 가동 범위를 반영한 맞춤형 재활 운동 콘텐츠 서비스가 안전하고 효과적인 재활을 지원할 수 있도록 한다.

근골격계 질환 재활환자들의 신체 능력을 평가하기 위한 주요 측정 도구로 관절 가동 범위(ROM: Range of Motion)가 사용된다. 본 논문에서는 근골격계 환자들의 재활운동을 통한 관절 가동 범위 정보를 시각적 이해하기 용이하도록 서비스하기 위하여 3차원 아바타를 이용한 관절 가동 범위 시각화 시스템을 제안한다. 제안하는 3차원 아바타를 이용한 관절 가동 범위 시각화 시스템은 근골격계 질환 재활환자들의 관절 가동 범위 데이터를 3차원 아바타의 대응하는 관절 작동 범위로 사상하고 다양한 시점으로 시각화하거나 애니메이션으로 재현함으로써 재활 수준의 변화를 직관적으로 제공할 수 있다.

최근 코로나 19 상황으로 인해 많은 사람들이 모이는 병원 방문을 꺼리거나, 치료비에 부담을 느끼는 근골격계 재활 환자들이 많다. 이러한 환자들을 위해 이 프로젝트에서는 재활 치료 빈도가 높은 어깨와 손목 등 여섯 가지 근골격 부위의 자가 재활 치료를 돕는 기계 학습 기반 웹 페이지을 구현한다. 이 웹 페이지는 각 부위에 대한 재활 치료 자세를 구글 티처블 머신으로 학습 시킨 데이터를 기반으로 환자가 올바른 자세로 운동하는지를 판별해 준다. 이 때, 사용자의 재활 치료 자세는 웹 카메라로부터 캡쳐한다.

The purpose of this study was to identify correlations between the musculoskeletal symptoms and job stress of occupational therapists at rehabilitation hospitals. To this end, the study conducted a survey on 210 occupational therapists at rehabilitation hospitals located in Seoul and Gyeonggi-do between June 1 and July 30, 2014. The average age of the subjects who participated in this study was $25.4{\pm}3.4$ years old, and their average work period was $2.3{\pm}2.1$ years. The subjects included 151 women (71.9%) and 171 permanent workers (81.4%). Among the subjects, 114 individuals (54.3%) had experienced a musculoskeletal symptom, and their major affected areas included hands/fingers (21%) and legs (18.6%). The percentage of high risk group of job stress was higher in musculoskeletal symptom group. And the proportion of high risk for job stress was higher in females. In particular, males showed significant differences in 'job demands', 'inappropriate reward', 'occupational climate' and females showed significant differences in 'Interpersonal conflict', 'inappropriate reward'(p<0.05).

우리나라에서 노령화가 급속히 진행됨에 따라 근골격계(뼈 및 관절부분)의 기능 장애는 개인의 삶의 질을 심각하게 저하시킬 뿐만 아니라 개인 및 국가 경제에도 큰 손실을 초래하고 있다. 현재 국내에서 사용되고 있는 근 골격계의 재생/재건/재활 관련 의료기기 대부분은 수입에 의존하고 있다. 고가의 수입제품의 사용은 심각한 경제적 손실 뿐 만 아니라 환자의 의료비 부담에 따른 양질의 의료혜택에도 지장을 주고 있다.(중략)

The mechanical system of wearable walking assist robot needs to be optimized for adapting with human body structure and the planned control algorithm should have a secure procedure when a incongruity situation which can cause musculoskeletal injury occurs because a wearable robot is attached to a body. The understanding of walking or musculoskeletal motions characteristics must be preceeded and analyzed for developing novel wearable walking assist robot. In this study we tried to find out the capacities of powers and torques of joint actuators to design optimized performances of system and to obtain the analysis data to figure out the characteristics of joint movements during some types of walk. The major types of walk and motion are stair climbing and descending, sit-to-stand motion, and slope walking. In this study all these motions were analyzed experimentally except slope walking.

Pulmonary rehabilitation has been known to improve dyspnea and exercise tolerance in patients with chronic lung disease, although it does not improve pulmonary function. The mechanism of this improvement is not clearly explained till now; however some authors suggested that the improvement in the skeletal muscle metabolism after the rehabilitation could be a possible mechanism. The metabolc changes in skeletal muscle in patients with COPD are characterized by impaired oxidative phosphorylation which causes early activation of anaerobic glycolysis and excess lactate production with exercise. In order to evaluate the change in the skeletal muscle metabolism as a possible cause of the improvement in the exercise tolerance after the rehabilitation, noninvasive $^{31}P$ magnetic resonance spectroscopy(MRS) of the forearm flexor muscle was performed before and after the exercise training in nine patients with chronic lung disease who have undertaken intensive pulmonary rehabilitation for 6 weeks. 31p MRS was studied during the sustained isometric contraction of the dominant forearm flexor muscles up to the exhaustion state and the recovery period. Maximal voluntary contraction(MVC) force of the muscle was measured before the isometric exercise, and then 30% of MVC force was constantly loaded to each patient during the isometric exercise. After the exercise training, exercise endurance of upper and lower extremities and 6 minute walking distance were significantly increased(p<0.05). There were no differences of baseline intracellular pH (pHi) and inorganic phosphate/phosphocreatine(Pi/PCr). After rehabilitation pHi at the exercise and the exhaustion state showed a significant increase($6.91{\pm}0.1$ to $6.99{\pm}0.1$ and $6.76{\pm}0.2$ to $6.84{\pm}0.2$ respectively, p<0.05). Pi/PCr at the exercise and the recovery rate of pHi and Pi/PCr did not show significant differences. These results suggest that the delayed intracellular acidosis of skeletal muscle may contribute to the improvement of exercise endurance after pulmonary rehabilitation.

This study aims to identify the relations between self-reported symptoms of industrial workers work-related musculoskeletal disorders and psychosocial factors. The subjects of the study were 120 male workers who were using the rehabilitation center of K company and they were voluntarily interviewed with a use of organized questionnaire. Except the responses from eighteen subjects whose responses were insincere and who had disorders in musculoskeletal areas, the responses of 102 ones were decided for the final analysis. The results showed that there were significant differences in self-reported symptoms of work-related musculoskeletal disorders between the subjects according to smoking, physical burden and self-efficacy. To prevent and control work-related musculoskeletal disorders, multi-characteristic aspects of how the disorders appeared and psychological factors, in particular, self-efficacy, should be carefully considered. Then, as psychosocial factors affect musculoskeletal disorders, relations between the disorders and factors should be analysed through long-term follow-up studies, psychosocial factors should be actively intervened, and the effect should be evaluated.
