Effects of Thoracic Spinal Exercise Program in VDT Workers: Pain Relief and Increased Flexibility: Young Ae Yang, Young Hee Kim, Yong Kwon Kim, Jin Gang Hur, Jae Cheol Song, Yoon Shin Kim; Korean Journal of Occupational and Environmental Medicine 2004;16(3):250-261.

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.

Relationship between the Serum CPK and the Shoulder Muscle Disorder in VDT Workers: Soo Keun Kim, Hae Kwan Cheong; Korean Journal of Occupational and Environmental Medicine 1998;10(2):172-179. Published online May 31, 1998; DOI: https://doi.org/10.35371/kjoem.1998.10.2.172

Abstract PDF: VDT workers are often exposed to static load in the shoulder stabilizing muscle due to repetitive work over long periods. Many investigations were reported the relationships between static load due to repetitive work and regional muscle disorder. However, diagnostic approach to work-related muscle disorder is difficult due to the absence of objective diagnostic tools. This study was performed to investigate the relationship between the serum CPK (creatine phosphokinase) concentrations and the shoulder muscle disorders. Results are as follow. 1. Mean serum CPK in total VDT workers was 67.6+/-28.4 IU/l and workers with abnormal serum CPK were 35 (21.5%). 2. Comparison between cases and controls did not show significant difference in the serum CPK level and the distribution of abnormal findings. 3. Sensitivity and specificity of the CPK test was 23.0% and 82.0%, respectively. Above results, in accordance with literatures, show that while serum CPK measure menu can be useful for the diagnosis of acute muscle injury, it does not adequately reflect the muscle disorders developed by the repetitive work of low tension over long time, such as VDT works.
