Abstract

This study investigated the symptoms of work-related musculoskeletal disorder(WMSDs) for physical therapists who have different work duties. We analyzed the symptoms in the musculoskeletal system and the degree of work-harmfulness by the survey of the symptom in the musculoskeletal system and rapid upper limb assessment(RULA) for pain control group(n=56), adult exercise group(n=53), and pediatric exercise group(n=22). As a result, 69.6% of the pain control group, 84.9% of the adult exercise group, 81.8% of the pediatric exercise group show the observable symptom. The adult exercise group has the biggest work load per hour in the final wrist & arm score of the ergonomic risk assessment using RULA. The action level of the pain control group is $3.0{\pm}0.9$; the Action Level of adult exercise group is $3.3{\pm}0.6$; the Action Level of the pediatric exercise group is $3.2{\pm}0.8$, and so it is shown that the adult exercise group has a problem of working posture. It is considered that devices and education system for preventing from WMSDs should come into wide use.

본 연구는 물리치료사의 직무에 따른 Work-Related Musculoskeletal Disorder(WMSD)s에 대한 증상을 파악하기 위하여 통증치료군(56명), 성인 운동치료군(53명), 소아 운동치료군(22명)을 대상으로 근골격계 증상조사표와 Rapid Upper Limb Assessment(RULA)를 사용하여 근골격계 증상 및 작업의 유해도를 알아보기 위해 실시하였다. 그 결과 통증치료군 69.6%, 성인 운동치료군 84.9%, 소아 운동치료군 81.8%, 평균 77.9%의 자각 증상 호소율을 보였다. RULA를 이용한 인간공학적 위험 평가에서 Final Wrist & Arm Score와 Final Score에서 성인 운동치료군이 단위 시간당 작업 부하량이 가장 많은 것으로 나타났으며 Action Level은 통증치료군이 평균 $3.0{\pm}0.9$, 성인 운동치료군은 $3.3{\pm}0.6$, 소아 운동치료군은 $3.2{\pm}0.8$로 성인 운동치료군에서 가장 높았다. 근골격계 증상에 영향을 미치는 요인 중 키, 가사 노동, 육체적 부담정도, 과거 사고가 통계적으로 유의하였다. 이에 따라 물리치료사의 WMSDs를 방지하기 위한 장비 및 교육시스템이 보급되어야 할 것으로 사료된다.
