ABSTRACT

Background: Work-related musculoskeletal disorders (WMSDs) are a common health problem throughout the world and a major cause of disability in the work­place. Awkward working posture, such as commonplace in batik industry, is a main risk factor for developing WMSDs. This study aimed to assess the effect of occupational chair on mitigation of musculoskeletal disorder among batik workers.

Subjects and method: This was a quasi-experiment study before and after with no control design conducted at a batik factory. A sample of 50 batik workers was selected for this study. The dependent variable was WMSDs. The inde­pen­dent variable was type of chair, which was ‘dingklik’ (short chair without back­rest, armrest, and hard seat) before intervention, and occupational chair (chair height= 28.39 cm; chair length= 39.74 cm; chair width= 39.73 cm; chair back height= 42.46 cm; chair back width= 39 cm) after intervention. The data of WMSDs were collected by survey instrument of skeletal muscle disorders from the Indonesian Ergonomic Association (PEI). The other data were collected by ques­ti­on­naire and observation. The data were analyzed by a logistic regression.

Results: Batik workers sitting on ‘dingklik’ had WMSDs, including pain, ache, and uncomfortable neck, shoulder, hip, and knee. Batik workers sitting on occupational chairs had no WMSDs.

Conclusion: Occupational chair is effective to prevent work-related musculo­skeletal disorders (WMSDs) among batik workers.
