Ergonomic rubber tapping knife relieves symptoms of carpal tunnel syndrome among rubber tappers

摘要

Background: Rubber tapping is an occupation with a high risk for developing carpal tunnel syndrome (CTS). Exposure to excessive ulnar deviation and wrist flexion, among other risk factors, contributes to increased carpal tunnel pressure contributing to the development of carpal tunnel syndrome. Prior, an ergonomic tapping knife was developed to improve wrist posture and to prevent or reduce CTS symptoms in rubber tappers. This study evaluated changes in the severity of symptoms of carpal tunnel syndrome after using the ergonomically designed tapping knife.
