Objective: This study examined the effects of working chair that was developed for farmers who work in grapevine’s
cluster thinning. Background: Agricultural work involves some of the nation’s highest occupational risk exposures. Fruit
cultivation has been recognized as one of the most hazardous crops in which to work. Grapevine cluster thinning task
involve activities related to the main risk factors associated with upper limb work-related musculoskeletal disorders. Method:
An experiment was designed to test the working chair. Six healthy male(25.8±4.9years) were selected as the subjects for
this study. Electromyography(EMG) was used to monitor the muscles activity, and Electro-goniometer was used to measure
the ranges of motions of the elbow, trunk and knee. Subjective test was also carried out to examine discomfort body parts
and their pain intensity. A grapevine’s working space was built for the experiment and working chair was installed on it. In
order to examine the muscle activity and range of motion, subjects used to the working chair for 30 minutes for each
experimental condition. Another test without working chair was also performed for comparison. %MVC was used to quantify
the level of muscle activity. Results: Decreases of muscle activity was found in all leg muscles and significant decrease of
muscle activity was found in left Gastrocnemius. The range of motion of the trunk and knee also decreased when working
chair used. Discomfort in lower back, thigh and shank region were reduced significantly. However, in upper limbs muscle
activity tended to increase in working chair compared with conventional task. Conclusion: Improvement for cushion in seat
back and pan required to reduce discomfort in buttocks. Application: Overall findings verified that the working chair might
help to prevent upper limb and lower back MSDs based on the current study. These results can be practically used for work
improvement for the grapevine growers to prevent MSDs.
