Investigating the relationship between the prevalence of carpal tunnel syndrome symptoms (CTS) and the dimensions of quality of life among computer users of 50 typing institutes

Carpal tunnel syndrome is followed by pushing Median nerve in the carpal tunnel of the wrist. Occupational factors such as repetitive movements of the hands and fingers and frequent wrist disturbances affect the development of this syndrome. Quality of life is a multidimensional concept including physical and mental performance. The aim of this study was to determine the prevalence of CTS and its impact on the quality of life of typists in Tehran.   This analytic descriptive cross sectional study was conducted in 1396 on 363 typists from 50 typing institutes in Tehran. Data were collected Demographic-Job Profile Questionnaire, Boston (BQ), quality of life (SF36) and Visual Analog Scale (VAS). Data were analyzed using SPSS-22 software and methods such as ANOVA and Pearson correlation tests. Among 363 participants, 215 of them were female (59.23%) and 148 were male (40.77%). The mean age was 37 ± 12.58 years. Among the typists, 51 (14.55%) had one-sided hand conflict, and 312 (85.95%) were two-sided hand conflicts. Results indicated that the prevalence of CTS symptoms among women was higher than that of men The value of Pearson correlation coefficient (range: 0.0613-0.783) showed that there was a moderate to strong correlation between the severity of symptoms scale (SSS), functional status scale (FSS) and visual analog scale (VAS) in the population under study (p< 0.05). There was also a strong and significant correlation between SSS and FSS among typists. In this study, CTS symptoms have a significant negative effect on the quality of life of the typists, but the psychological dimension quality of life is not to be affected by these symptoms. Regarding the existence of CTS symptoms among typists who work most of a day with computers, there is also a statistically significant relationship between the incidence of CTS symptoms and the quality of life in this occupational group. Therefore, it is recommended that more attention should be paid to these individuals, appreciate tools be correctly designed, and further study be done.
