Carpal tunnel syndrome in carpet workers
Objective: Repetitive and forceful use of wrist and finger flexors is purported to be an occupational risk factor for carpal tunnel syndrome (CTS). While weaving carpet, wrist and finger flexors and extensors are used repetitively, with pinching movements and forced grasping. We aimed to investigate CTS frequency in hand-made carpet workers. Methods: Seventy women from carpet workshops in the city center and 30 healthy unemployed women were evaluated by clinical examination and electrophysiology. The relationship between CTS development and employment duration, and work produced per year were also investigated. Our study is cross-sectional. Results: CTS was present in 31 hands (22.1%) of workers and in four hands (6.7%) of the control group. The estimated relative risk of developing CTS was 3.3 times greater in carpet-workers than it was in controls. Considering all hands, we could not find any correlation between CTS development and employment duration (P=0.977), or with work produced per year (P=0.505); but these two were the prominent factors contributing to delayed median sensory latency (P=0.013, P=0.009, respectively). Conclusions: We could not find any correlation between CTS development and employment duration, or with work produced per year; but these two were the prominent factors contributing to delayed median sensory latency The results indicates that women working in the hand-made carpet industry have a higher risk of CTS development.
