Abstract

Grip strength is the force applied by the hand to push objects and is a specific part of hand strength. It is generally considered that all aspects of the hand must be exercised to produce a healthy and strong hand. Repetitive usage of hands will cause an imbalance between closing and opening (antagonist) muscles, and can lead to problems such as carpal tunnel syndrome. The purpose of this study is to analyse the hand press grip force and muscle fatigue at the left and right triceps for push activity among the workers in the aerospace industry while workers perform their task. By using observation, interview, questionnaires, Tekscan system and Electromyography (EMG) tools is used to evaluate hand pressure grip force and muscle fatigue of the workers. Findings will show the factors that affect the hand pressure grip force and its relation with muscle fatigue. At the end of this study, the result will be discussed to achieve the objective and also propose an ergonomic improvement in the aerospace industry.
