Abstract:
Objective -
To analyze the effect of using vibration tools on the prevalence of work related musculoskeletal disorders
（ ） Methods ， -
WMSDs in automobile factory workers. By judgment sampling method front line workers with more than one year
of working experience in an automobile factory were selected as the research subjects. Musculoskeletal Disorders Questionnaire
was used for investigation. The workers were divided into the control group and the vibration tool group. The propensity score
∶ ，
matching method was used to balance the confounding factors of the two groups of workers by 1 1 and 568 people were
Results
included in each group. The prevalence of WMSDs was compared between the two groups after matching. After

matching the prevalence of WMSDs in the shoulder elbow hand/wrist upper back waist hip/buttock and knee of workers in

the vibration tool group was higher than that in the control group and the differences were statistically significant all <0.05 .，
The prevalence of WMSDs in different body parts of workers in the vibration tool group ranking from high to low was waist

54.0% 50.9% 39.4% 35.2% 31.0% and 27.1% respectively <0.01 . The use of vibration tools can

increase the risk of WMSDs in shoulder elbow hand/wrist upper back waist hip/buttock and knee of automobile factory
workers. Corresponding measures should be taken to reduce vibration intensity and reduce contact time to protect workers'
