Objective: To determine the prevalence of cumulative trauma disorders (CTDs) in laundry service, related factors, and concordance with Lom Plai Pattakad Disorders (LPPDs) in applied Thai traditional medicine (ATTM).
Study design: Descriptive study
Setting: Laundry service unit at Siriraj Hospital
Method: Staff of the laundry service unit at Siriraj Hospital volun-teered to meet a rehabilitation medicine resident doctor and an applied Thai traditional medical practitioner for diagnosis of CTDs and LPPDs respectively. General Health Questionnaire (Thai GHQ–28) was used to assess mental health and the score equal or more than 5 was considered abnormal. The common CTDs such as low back pain (LBP), neck pain, and upper limb disorders, were studied. Concordance between the CTDs and the LPPDs in the same pain region was assessed.
Results: In total, 132 of 151 workers participated in the study. The participation rate was 87.42%. Mean age was 40 (SD 10.4) years. The prevalence rates of all CTDs, LBP, neck pain, and de Quervain’s tenosynovitis were 72.7%, 51.5%, 42.4%, and 11.4% respectively. Factors significantly related to CTDs (p<0.05) were Thai GHQ-28 score ≥5 and lower frequency of exercise. Factors significantly related to LBP (p<0.05) were age, Thai GHQ-28 score ≥5 and lower frequency of exercise. Factors significantly related to neck pain (p<0.05) were female gender, Thai GHQ-28 score ≥5, more working hours per week, low social support, and lower frequency of exercise. The concordance between CTDs and LPPDs was 80.9% (kappa=0.517).
Conclusion: The high prevalence of CTDs, over 70%, was found in laundry service workers. Related factors are abnormal Thai GHQ-28 scores and lower frequency of exercise. High overall concordance between CTDs and LPPDs confirmed that both abnormalities were detected similarly by conventional medicine and ATTM in this population and suggested clinical significance.
