Carpal tunnel syndrome in women working in tea agriculture

Abstract

OBJECTIVE: The aim of this cross-sectional study was to determine the frequency of carpal tunnel syndrome (CTS) among women using tea leaf scissors and compare it with normal population. METHODS: Two hundred hands of 100 women using tea leaf scissors (tea leaf scissors group) and 112 hands of 56 healthy women (control group) were clinically and electrophysiologically evaluated for CTS. Women using tea leaf scissors were evaluated with visual analog scale (VAS) for pain and Boston Carpal Tunnel Syndrome Questionnaire for symptoms and functional status. RESULTS: Carpal tunnel syndrome was diagnosed bilaterally in 62 (62%) and unilaterally in 7 (7%) women using tea leaf scissors, whereas 2 (3.57%) bilateral and 6 (10.71%) unilateral cases of CTS was diagnosed in controls. The differences in demographic factors were not statistically significant. In women with CTS using tea leaf scissors, mean symptom severity, functional status, and VAS scores were 2.73+/-0.60, 2.42+/-0.71 and 5.19+/-1.84, respectively. There was statistically significant difference in the frequency of CTS between women using tea leaf scissors and the control group and the risk of having CTS among women using tea leaf scissors was approximately 12 times greater (p<0.001). CONCLUSION: In tea agriculture, working with repetitive flexions and extensions of the wrist highly increases the risk of developing CTS.
