Survey on the Prevalence of Carpal Tunnel Syndrome in Simple Repetitive Workers Who Use Upper Extremities: Ji Eun Son, Tae Woon Jang, Yoon Kou Kim, Young Seoub Hong, Kap Yeol Jung, Dong Ill Kim, Kang Jin Lee, Nam Jin Ha, Sang Boum Kim, Joon Youn Kim; Korean Journal of Occupational and Environmental Medicine 2001;13(3):209-219.

OBJECTIVES
This study was carried out to survey on the prevalence of Carpal Tunnel Syndrome(CTS) in high risk jobs(meat and fish processing plant and wood plant), by application of Nerve Conduction Study(NCS), a confirmatory diagnostic method.
METHODS
Experimental group was 69 workers sampled from meat and fish processing plants and 17 workers sampled from wood plants, who were simple, repetitive workers using upper extremities and control group was 28 workers sampled from managers, secretaries and keepers. All employees were examined through work history, physical examination and NCS.
RESULTS
18 workers(26.09%) in meat and fish processing plants, and 5 workers(29.41%) in wood plants had compatible findings to NIOSH diagnostic criteria for CTS. The experimental group had more symptoms(complaint of upper extremities, Visual Analogue Scale >or= 4(VAS: total 10 point)), signs(Tinel and Phalen test) and prevalence of CTS than control group ( p<0.05). The prevalence of symptoms and signs were higher in short term worke r s (<7 years), but the prevalence of CTS was higher in long term workers(>or=7 years).
CONCLUSIONS
The prevalence of CTS in meat and fish processing plant and wood plant were 26.09% and 29.41% respectively. Authors propose that meat and fish processing and wood plants should be managed as a risk job category which were designated by OSHA in 1996

Abstract PDF

The objectives of this study were to investigate the prevalence and risk factors of occupationally related carpal tunnel syndrome (CTS) among workers employed in services and manufacturing industries analysing the sensitivity and specificity of clinical symptoms and signs. Three surveys were made for this study. The first survey was done for 1,447 workers employed by 25 companies. The jobs of the employees were repetitive works at VDT and assembly lines. Therefore, employees could be divided to two groups, doing repetitive works and non repetitive works. The second survey was made for 189 workers who were randomly selected from 517 workers complained some symptoms at their hands and wrists. We examined their symptoms and carried out neurological examinations for CTS (Tinel's sign, Phalen's sign, pin prick test, carpal compressive test, toniquet compression test). The third survey was made for nerve conduction study (NCS) for 57 workers who had shown positive signs for CTS. The main results of this study were as follows: 1. From the first survey, we have found that there were significant statistical differences in getting uncomfortable neuromuscular symptoms by sex, job type, total working hours during a week, duration of current work, and kinds of work. Odds ratio in male vs female, repetitive vs non repetitive, service vs manufacturing companies, total working hours during a week, and duration of current work were 1.867(95% CI=1.467-2.377), 1.680 (95% CI=1.121-2.279), 1.663(95% CI=1.213-2.279), 1.016(95% CI=1.006-1.027) and 1.283 (95% CI=1.097-1.501) respectively. 2. From the second survey, we have found that 46 peoples (25.0%) were positive for one or more than one signs in neurological examinations of NIOSH criteria. Positive findings from neurological examinations were high among workers of low level of education (p-value=0.008), manufacturing jobs (p-value=0.00), long hours a week (p-value=0.028), and long duration of current work (p-value=0.00). 3. From the third survey, we diagnosed 35 peoples (61.4%) had CTS by NCS. They had abnormally delayed latent period or velocity in median nerve conduction velocity.
