Abstract

This research is about the study of the human thumb structures and its bones. This research is to gather information on key pinch strength/force and the stress exerted throughout the thumb among Malaysians and analyze it using finite element analysis (FEA) so that it can be used for future references. Data for this research are gathered and collected from data of previous study similar to this topic being researched. Previous data contains 120 samples but only 60 will be used to analyze in this research. If the outcomes/results of the analysis are not satisfying enough, more data will be selected or gathered manually so that proper analysis can be done correctly. The initial 60 samples from the group of 120 samples are in the age group of 22-40 years old, consist of 3 races which are the Malays, Chinese, and Indians, data are from both the left and right hand, and out of the 60, 30 are males and remaining 30 are females. Till this point in research, one of the main findings is that many has said that improper use of pinching activities whereas its limitations has been reached can cause diseases such as carpal tunnel syndrome (CTS) and thumb arthritis. This is why a proper research is needed so that diseases like these can be avoided when performing daily tasks. Other findings include data for the pinching exercise is mostly collected from the western population but very minimal in Malaysia. Data derived from western populations cannot be applied to a comparable Malaysian general public. Gender, hand dominance, age, and weight must be considered when establishing normal values for pinch strength and the stress exerted on the bones.
