THE ASSOCIATION BETWEEN MUSCULOSKELETAL DISORDERS WITH WHOLE-BODY VIBRATION FROM THE SEAT OF FORKLIFT DRIVERS IN A WAREHOUSE DEPARTMENT IN CHACHOENGSAO PROVINCE
Keywords:
Musculoskeletal disorders (MSDs) , Whole-Body vibration, Forklift driversAbstract
The objective of this study was to investigate the symptoms of musculoskeletal disorders (MSDs) in forklift drivers, and to study the association between whole-body vibration while driving a forklift and musculoskeletal disorders. This was a cross-sectional analysis study. The Musculoskeletal Symptom Severity and Frequency Questionnaire (MSFQ) was used to collect data, as well as three whole-body vibration measures of forklift drivers at work and take the vibration meter values to assess the results. The results of the study found that the musculoskeletal disorders, considering the severity of moderate or higher of forklift drivers, discovered that the majority of employees had symptoms of abnormal musculoskeletal system from discomfort in the lower back, which ranked first at 47.06 %t, followed by feet and ankles at 29.41 %, and upper back and calves at 23.53 %. Personal factors, specifically gender and body mass index (BMI), were found to be significantly associated with the occurrence of musculoskeletal disorders in forklift drivers in the warehouse department (p-value <0.05). The results of the study found that the measured whole-body vibration was not a direct cause with statistical significance (p-value<0.05) that affects the Musculoskeletal disorders of forklift drivers. However, the small sample size may have limited the study's ability to detect an association. There are many more factors that could affect the study. As a result, in order to conduct future research, it is required to investigate other factors that may influence overall body vibration.
