Abstract
OBJECTIVES: The aims of present study were to determine the prevalence of work-related musculoskeletal disorders (WRMSDs) among sonographers in China and to provide evidence for appropriate intervention measures to be taken. METHODS: A self-reported questionnaire was used to screen WRMSDs experienced by sonographers during the past 12 months. This questionnaire survey was created and hosted on the WeChat official account platform for sonographers. RESULTS: In the present study, 567 sonographers from 521 medical institutions completed the questionnaire. The vast majority (99.3%) of respondents reported experiencing symptoms of WRMSDs for at least one body region during the past 12 months. Work-related musculoskeletal pain or discomfort was most frequently reported for the neck (95.1%), right shoulder (84.1%), lower back (82.4%), right wrist/hand (81.0%), upper back (78.1%), right forearm/elbow (72.0%), and left shoulder (66.1%). Scanning hours per day, number of patients per day, and years of experience were positively associated with the occurrence and frequency of experiencing WRMSDs of some common and specific anatomical regions. Taking a regular rest break during the scanning working day was associated with a reduction of WRMSDs of the right shoulder and right wrist/hand. Adopting a sitting posture while performing scanning was associated with a reduction of WRMSDs, particularly for the lower back and the neck. Performing regular physical activity during leisure time was associated with a reduction of WRMSDs of the neck. CONCLUSIONS: The prevalence of WRMSDs among sonographers in China was extremely high. It is necessary and essential to reduce the number of scanning hours and patients per day, adopt a sitting posture while performing scanning, schedule regular rest breaks during the scanning working day, and encourage performance of regular physical activity during leisure time to alleviate this WRMSD issue experienced by sonographers.
