Effect on Active Exercise Programs in Employees with Chronic Low Back Pain: Jin Gang Hur, Jae Cheol Song, Young Man Roh, Dong Sik Park, Young Ae Yang, Yoon Shin Kim; Korean Journal of Occupational and Environmental Medicine 2005;17(1):44-57. Published online March 31, 2005; DOI: https://doi.org/10.35371/kjoem.2005.17.1.44

OBJECTIVE: To examine the relative efficacy of three active exercise programs for work-related, chronic low back pain, and to observe to what extent the programs affected the mechanical stability of the lumbar region.
METHODS
The subjects were 64 employees who were randomly divided into three groups to match the three active exercise programs which were performed 3 times a week for 6 months. All subjects were assessed with the same measurements at a pre-study examination, and then were reassessed at 2 weeks, 3 months and 6 months after the study.
RESULTS
The pain intensity didn't show any significant difference among the three groups. However, the Oswestry Disability Index showed significant differences among the three groups at 6 months and the lumbar and thoracic exercise groups showed significant decreases compared to the general physiotherapy group (p<0.05). Maximal stretching with both hands in the overhead direction showed a significant difference among the three groups at 3 months and 6 months, and the thoracic exercise group at 6 months showed a significant increase in overhead stretching compared to the lumbar exercise and general physiotherapy groups (p<0.05). The lumbar region angle of inclination showed significant differences among the three groups at 2 weeks, 3 months and 6 months, with the thoracic exercise group being decreased significantly more than the lumbar exercise and general physiotherapy groups at 6 months (p<0.05).
CONCLUSIONS
Exercise aimed at increasing thoracic mobility has an effect on lumbar stability. Furthermore, it is far more effective for lumbar stabilization than general physiotherapy and deep muscle strengthening lumbar exercise.

Published online September 30, 2004; DOI: https://doi.org/10.35371/kjoem.2004.16.3.250

Abstract PDF

OBJECTIVES
The purpose of this study of the Thoracic Spinal Exercise Program was to evaluate its effects on VDT workers. These effects were found to include a decrease thoracic kyphosis, increase thoracic spine mobility and decrease in the VAS (visual analog scale). These measures provide a means of assessing the muscle endurance and muscle strength of the subjects.
METHODS
This study was conducted during the period from July 1 to August 31, 2003, and involved 58 VDT workers belonging to a company located in Seoul who were working seated in front of a computer for most of the day. After applying the thoracic exercise program, we examined the changes in the of thoracic kyphosis angle, spinal length (C7-S3), TFED (thoracic flexibility in the extension direction), MEBH (maximal elevation with both hands in the overhead direction) and CE (chest expansion).
RESULTS
Obtained f om this study are as follows. 1. A significant reduction in the VAS was observed in the exercise group (pre-exercise 5.90 +/- 0.88 points, post-exercise 4.23+/- 0.82 points), as compared with the control group (pre-exercise 6.00+/-0.90 points, post-exercise 5.93+/-0.81 points). 2. A significant reduction in thoracic kyphosis (pre-exercise 36.97+/-7.49, post-exercise 31.83 +/-5.90) and a significant increase in thoracic flexibility in the extension direction (pre-exercise 7 . 4 7+/-2.30, post-exercise 11.77+/-3.65) were observed in the exercise group. The thoracic kyphosis angle showed a significant reduction in the exercise group, as compared to the control group. The thoracic flexibility in the extension direction showed a significant increase in the exercise group, as compared to the control group. 3. There was a significant increase in the spinal length in the exercise group (pre-exercise 494 +/-27.66 mm, post-exercise 518.60+/-27.95 mm).
CONCLUSIONS
The Thoracic Spinal Exercise Program results in an increase in thoracic spine mobility and a decrease in pain. In practical terms, the effects of the exercise program are good health and posture.

Abstract PDF

Objectives
The prevalence of cumulative trauma disorders of upper extremities mons watch assembly workers in small-scaled industry was studied.
Methods
In 83 workers at five watch assembly factories, symptoms and psychosocial questionnaire, ergonomic Interview, physical examination were conducted.
Results
Prevalence of self-reported symptoms was 54.2% and neck 34.9%, wrist/hand 31.3%, shoulder 30.1%, elbow/arm 18.0% by anatomical site. Prevalence of cumulative trauma disorders was 45.8%. Most common disease was myofascial pain syndrome (31.3%). The other diseases were De Quervain disease (9.6%), tenosynovitis/tendinitis at wrist/hand (9.6%), bicipital tendinitis(6.0%), fat. epicondylitis(4.8%), meIn. epicondylitis(2.4%), and cervical disc disease(2.4%). As result of ergonomic interview, repetitiveness was 79(98.8%). There were no differences in the prevalence of self-reported symptoms and cumulative trauma disorders for age, sex, marital status, duration of work In the study, The significant factors of cumulative trauma disorders were occupational task and psychosocial stress in the study. The prevalence of cumulative trauma disorders in high strain group was hlgher (68.4%) than other three groups. The prevalence of self-reported symptoms and cumulative trauma disorders in assembly task was higher (70.0%, 64.0%) than other two tasks.
Conclusions
Prevalence of self-reported symptoms was 54.2%, prevalence of cumulative trauma disorders was 45.8% in watch assembly workers. In this study, factor related to self-reported symptoms was occupational task and factors relaxed to cumulative trauma disorders were occupational task and psychosocial stress. This results suggest that differences of ergonomics and environment in occupational task cause differences of prevalence of self-reported symptoms and cumulatlve trauma disorders.

Protective Effects of the NMDA-receptor Antagonist (MK-801) for the Brain Injury by Oxygen Free Radical: In the Hyperbaric Oxygen Treatment of CO Poisoned Rat: Dae Eun Jung, Seung Ho Ryu, Jin A Cho, Jae Cheol Song, Hung Bae Park; Korean Journal of Occupational and Environmental Medicine 1997;9(1):40-48. Published online February 28, 1997; DOI: https://doi.org/10.35371/kjoem.1997.9.1.40

Abstract PDF: The effects of NMDA-receptor antagonist (MK-801) were assessed for the oxygen free radical mediated brain (hippocampus) injury with eighty rats which were exposed to carbon monoxide (CO) followed by hyperbaric oxygen (HBO) treatment. Superoxide dismutase (SOD) and malondialdehyde (MDA) were used as parameters of the oxygen free radical reaction. Experimental groups consisted of (1) control group (=breathing with air), (2) CO group (=exposed to CO after air breath), (3) CO-air group(exposed to CO after air breath followed by air breath), and (4) CO-HBO group (=exposed to CO after air breath followed by 3 ATA HBO). Each group was divided two subgroup according to the pretreatment (normal saline or MK-801). CO, CO-air and HBO groups increased in SOD activity as compared with control group. And CO-air and HBO groups increased in MDA as compared with control and CO group. Pretreatment of MK-801 decreased SOD activities significantly (p-value<.05) , but MDA amount not significantly (p-value=.107). These results suggest a useful protective effect of NMDA-receptor antagonist (MK-801) in CO induced hippocampal injury mediated by oxygen free radicals.

Abstract PDF

The purpose of this study is to investigate the relationship between the self-reported musculoskeletal symptoms and related factors among VDT operators in bank. The subjects were 950 women workers. The characteristics of subjects were 26.6 years of average age, 5.7 years of average VDT use duration and 6.5 hours of daily VDT use time. The results were as follows. The prevalence of self-reported musculoskeletal symptoms more than severe in Likert scale were 51.4%, 43.9% at the shoulder, 38.3%, 31.8% at the lower back, 38.0%, 31.3% at the neck, 31.2%, 25.2% at the upper back, 21.7%, 16.5% at the wrist and 13.6%, 8.8% at the fingers (while on duty, after home-coming). General characteristic variables affecting the musculoskeletal symptoms were married, number of child and daily house-working time. Work-related factors affecting the musculoskeletal symptoms were VDT working career, daily working time, daily VDF use time, VDF use time without rest, daily work-load and regular rest. As the result of the multiple logistic regression analysis, daily working time, daily VDT use time and VDT working career were significant variables accounting for the musculoskeletal symptoms.
