Characteristics and Relevant Factors of Individuals Diagnosed with De Quervain's Tenosynovitis (DQT) in Bangladesh

Abstract

Background: De Quervain's Tenosynovitis (DQT) is a highly frequent condition that affects people of all ages. It is an inflammation of the tendons, specifically affecting the abductor pollicis longus (APL) and extensor pollicis brevis (EPB) that run along the thumb side of the wrist and attach to the base of the thumb. The condition is commonly associated with repetitive strain and overuse, particularly among individuals engaged in manual labor or activities requiring sustained wrist movements. Aim: This study aimed to comprehensively understand the characteristics and relevant factors of individuals diagnosed with De Quervain's Tenosynovitis (DQT) in Bangladesh. Methods: A cross-sectional quantitative study was conducted with 60 participants who received DQT treatment at the Centre for Rehabilitation of the Paralysed (CRP). Data were collected through face-to-face surveys using a self-developed questionnaire. The findings were analyzed using descriptive statistics in SPSS version 20. Results: The study included 60 patients, 68.3%(n=41) of whom were female, and the average age was 39.55. The dominant hand was affected in 80% (n=48) of the cases, and in 51.7% (n=31) of participants, the right hand was involved. The commonest symptom reported was pain in 91.7%(n=55) of them, out of which 65.5%(n=36) had extreme pain while doing thumb movements. Occupational risk factors were identified in 100% (n=60) of participants, with repetitive hand and wrist activities being the predominant contributing factor. Most participants (71.7% (n = 43)) reported the frequent usage of smartphones or computers, and 30.2% (n = 13) used devices over 6 hours per day. 61.7% (n=37) of participants rated ergonomic practices as "fair," and 45% (n=27) reported they did not take breaks during repetitive tasks. Conclusion : This study shows that De Quervain's Tenosynovitis (DQT) has a strong correlation with repetitive activities, in which the female gender and dominant hand have become the most likely identified risk factors. It highlights the significance of ergonomic knowledge, workplace modification, and targeted intervention adopted to control and prevent DQT in Bangladesh. These help in evidence-based practice, leading to improved occupational therapy outcomes for affected individuals.
