As they do repeated work like carrying weighty material, it causes musculoskeletal disorder. In particular, in agricultural work, what is going to be repeated, is as digging hole, throwing soil that causes them to bend a physical burden. To solve such problems, we aims at attaching extra handle on agricultural instruments such as shovel, hook, sickle so that they can prevent injury and help efficacious job.
To invent extra handle, we have selected the shovel as typical agricultural instrument and investigated which parts of body they use most in farming and what causes discomfort based on survey by twenty farmers. We produced primary prototypes based on those assessment and measured %MVC and cognitive uncomfortable degree (Five scores scale) by shovel work using general shovel people have been using and prototype we have invented. The representative subjects for %MVC were six in total: Left/right biceps, deltoid, and elector spinae and we measured subjective rate of discomfort in five parts of body: Neck, shoulder, arm, waist, and hand. In result of measurement, it demonstrated statistically highest %MVC in every part when they worked, with generally-used shovel more than when they used the shovel with extra handle. Especially, it showed twice of difference in elector spinae (With general shovel: 48.3; with newly invented shovel: 25.3). According to result of subjective uncomfortable degree, people have felt much more discomfort in every part except for hands when working with shovel. Particularly, it showed much highest in waist(With general shovel:4.5; with newly invented shovel: 3).
By inventing extra handle for agricultural instrument, we expect that it is going to solve those problems, preventing musculoskeletal disorder and make agricultural job more efficacious.
