In order to investigate symptoms prevalence related to visual display terminal(VDT) syndrome, and to evaluate the variables affecting the development of the VDT syndrome, a questionnaire survey was conducted on 119(92 men and 27 women) VDT operators who had been engaged in one plant design company in seoul. The results were as follows : The average age of questionnaire respondents was 30. The average years of service were 4.3 years, and the working hours per day with VDT for half of them were more than 4 hours with the average being about 4.7 hours. The majority of subjects(71 persons) were working at computer aided design(CAD) or computer programming tasks. Subjective symptoms of VDT syndrome were divided into 4 groups with musculoskeletal, eye, skin, and industrial fatigue according to their major affected organ. A high incidence of complaints of eye discomfort was observed. In the 3 subgroups of industrial fatigue symptom, the highest average group score was accounted for by 'dullness and sleepiness', followed by 'difficulty in concentration', 'bodily projection of fatigue' in the order of sequence, suggesting the heavier mental stress of VDT work rather than physical burden. Relationship among these 4 groups of symptoms showed statistically significant correlations one another. This result suggests that VDT syndrome is a multi-organ disease composed of these 4 symptom groups which were commonly caused by the use of VDT. Multiple regression analysis were used to examine the relationship between risk factors and these symptom groups of VDT syndrome. As the result of analysis, the most important risk factor for VDT syndrome was the average daily VDT working hours. The longer was VDT working hours, the higher was symptom prevalence of VDT syndrome. In addition, daily total working hours including VDT working hours and shift of work also affected the health of VDT users. In order to protect workers from VDT syndrome, it is urgently required to implement standard management recommendations including restriction of VDT working hours and allowance of more sufficient resting time for VDT workers.

서교철,박승환,조미숙 한국융합학회 2021 한국융합학회논문지 Vol.12 No.11

본 연구는 스마트폰을 장시간 사용으로 VDT증후군(Visual Display Terminal Syndrome)을 가진 20대 성인들을 대상으로 체외충격파 치료(ESWT)를 통해 목-어깨의 근육의 복합적 통증지수에 미치는 영향을 알아보고자 한다. VDT증후군 으로 목-어깨통증을 가지고 있는 대상자 20명을 무작위로 분류해서 실험군 10명과 대조군 10명으로 나눠서 실험에 참여하였다. 실험대상자들은 4주간, 주 5일간 실시하였다. 실험군은 1회 5 Hz, 2.0 bar의 강도로 체외충격파치료를 2000회씩 실시하였고, 대조군은 1회 30분간 자가신장운동을 실시하였다. 실험대상자들은 실험전과 실험후에 VAS와 PPT로 목-어깨통증을 측정하여 비교하였다. 자료분석은 SPSS win 18.0으로 실험전과 실험후에 실험군과 대조군의 결과값을 분석하기 위해 독립비교를 실시 하였다. 실험 후 실험군이 목-어깨근육의 VAS, PPT에서 많이 감소하였다. 하지만 대조군은 큰 차이가 없었다. 이런 결과를 통해 체외충격파 치료는 치료전보다 치료후에 통증감소가 나타났지만 자가신장운동은 치료후 통증감소의 차이가 없었다. 앞으 로도 VDT증후군의 원인으로 목-어깨통증을 감소시킬 수 있는 다양한 치료법으로 이용될 것으로 사료된다. The purpose of this study was to determine the effect of extracorporeal shock wave therapy for the neck-shouler muscles of complex pain scales of the 20s adults with VDT Syndrome to prolonged smartphone use. Twenty subjects with neck pain due to VDT syndrome participated in the experiment. They were randomly divided into 10 experimental groups and 10 control groups. Experimental subjects were conducted for 4 weeks, 5 days a week. The experimental group was subjected to extracorporeal shock wave therapy 2000 times at an intensity of 5 Hz and 2.0 bar once, and the control group performed self-stretching exercise for 30 minutes once. Subjects measured and compared neck-shoulder pain with VAS and PPT before and after the experiment. Data analysis was performed with SPSS win 18.0, and correspondence comparison was performed to analyze the results of the experimental group and the control group before and after the experiment. After the experiment, the experimental group decreased more in VAS and PPT of the neck-shoulder muscle. but the control group was no difference. Though these results, extracorporeal shock wave therapy was showed a reduction in pain after treatment than before treatment but there are no difference in the pain reduction after self-stretching exercise. Thus, extracorporeal shock wave therapy is expected to be used as a variety of treatments to reduce neck-shoulder pain as a cause of VDT syndrome.

장경숙,정영미 한국산학기술학회 2024 한국산학기술학회논문지 Vol.25 No.11

본 연구의 목적은 사무직 근로자의 영상표시단말기(VDT: Visual Display Terminal)증후군 예방행위를 파악하고 건강신념이 이에 미치는 영향을 확인하고자 시도되었다. 본 연구의 대상자는 VDT증후군 예방관리 교육을 시행하고 있는 직장에서 교육을 받은 사무직 근로자이었으며 자료는 일반적 특성, 컴퓨터 사용실태, VDT증후군 예방행위, 건강신념 측정도구로 구성된 구글설문지를 이용하여 2024년 3월 1일부터 15일 간 수집되었다. 최종 183명의 자료를 기술통계, t-test, Pearson’s 상관계수와 위계적 다중회귀분석을 사용하여 분석하였다. 연구결과 ‘20/20/20/규칙’, ‘블루라이트사용’, ‘안구운동과 마사지’, ‘정기적 눈 건강검진’, ‘1시간마다 휴식하기’, ‘컴퓨터 작업 중 눈을 자주 깜빡이거나 인공눈물 사용하기’와 같은 개인의 의식적인 노력이 필요한 예방행위의 수행률이 상대적으로 낮았다. 건강신념 중 행동 촉발요인(β=0.35, p<.001), 자기효능감(β=0.18, p=.049), 인지된 유익성(β=0.17, p=.026)이 VDT증후군 예방행위에 영향을 미치는 것으로 확인되었다. 따라서 사무직 근로자의 VDT증후군을 예방하기 위해서는 컴퓨터 작업 중 자발적이고 지속적으로 행동을 유도할 수 있도록 신뢰할 수 있는 정보나 교육을 반복적으로 제공하고 목표달성에 대한 긍정적인 피드백과 적절한 보상을 하거나 예방행위에 대한 명확한 결과를 제시하는 것이 필요하다. The purpose of this study was to identify VDT (Visual Display Terminal) syndrome preventive behaviors among office workers and examine the impact of health beliefs on these behaviors. The study participants were office workers who had received VDT syndrome prevention management education at their workplaces. Data were collected using a Google survey from March 1 to March 15, 2024, which included measures of general characteristics, computer usage patterns, VDT syndrome preventive behaviors, and health beliefs. One hundred and eighty-three responses were analyzed using descriptive statistics, t-tests, Pearson's correlation coefficients, and hierarchical multiple regression analysis. The results showed relatively low performance rates for preventive behaviors that require the conscious efforts of individuals, such as the '20/20/20 rule', 'blue light usage', 'eye exercises and massages', 'regular eye check-ups, and 'taking breaks every hour'. Cues to action (β=0.35, p<.001), self-efficacy (β=0.18, p=.049), and perceived benefits (β=0.17, p=.026) were health beliefs that influenced VDT syndrome preventive behaviors. To prevent VDT syndrome among office workers, it is essential to repeatedly provide reliable information or education that encourages voluntary and sustained actions during computer use and to support these activities by providing positive feedback, appropriate rewards for goal achievement, and presenting clear outcomes of preventive behaviors.

The Association between myofascial pain syndrome and some tests was assessed in a cross-sectional study of 904 female telephone operators using video display terminals(VDTs). 105 cases were diagnosed as Myofascial pain syndrome with symptom questionnaire, laboratory examination and physician's physical examination and 550 controls were defined to show only musculoskeletal symptoms using NIOSH symptom criteria. Data on demographics, musculoskeletal symptom and visual analogue scale(VAS) were obtained by questionnaire. Anthropometric measurements, pressure pain threshold, Grip & Pinch strength and laboratory test were conducted. No significant difference between case and control at comparing of demographics, occupational history and body measurements were observed. But, Grip strength, pressure pain threshold and VAS showed the statistical difference between case and controt. Age, pressure pain threshold of Rt. Upper trapezius and VAS were associated with myofascial pain syndrome in multivariate logistic regression analysis. This results suggest that, to diagnose of myofascial pain syndrome, the consideration of the objective aspects among patients' subjective symptom complaints through the VAS and pressure pain threshold is required.

The purpose of this study was to investigate the effects of working environment and intervention exercise programs for office workers with Visual Display Terminal Syndrome (VDTS) on musculoskeletal disease related to Neck Disability Index (NDI) and Spinal Curvature (SC). For the control group (n = 8) modifications in the working environment such as the height and position of the monitor, the desk and the chair, the angle of the keyboard and the brightness of the monitor screen were applied, and the experimental group (n = 13) experienced the working ergonomic modification as well as a stretching and stabilization exercise program to strengthen core muscles for 8 weeks (3 times a week). As a result, based on the reference angles of 48 degrees for thoracic spine and 40 degrees for lumbar spine, experimental group showed positive changes in thoracic and lumbar spine curvature (p <.01). In addition, the NDI showed a significant improvement in the experimental group compared to the control group as a result of comparing the pre to post difference (p <.01). Improving the symptoms of VDTS with ergonomic intervention is not sufficient, and it is thought that an additional intervention of mid- and long-term exercise program may be necessary for significant improvement of musculoskeletal diseases. It is recommended that office workers with computer work environment may need to apply ergonomic intervention as well as axial skeleton and core muscle oriented exercise program for long period of time to reduce VDTS-based symptoms.
