Antropometric Based Optimization Of Wheelchair Design For Enhanced User Ergonomics

Abstract

Background: Wheelchairs are vital mobility aids for many individuals,especially the elderly. However, wheelchair designs that do not meet the ergonomic needs of users can cause discomfort and health problems.This study aims to identify the ergonomic needs of elderly wheelchair users, analyze the suitability of existing wheelchair designs on the market and develop ergonomic design recommendations using an anthropometric approach.

Method: This research uses anthropometric methods and the data is analyzed using data normality test, data uniformity test, data sufficiency test and percentile calculation to determine optimal design criteria. The analysis shows that there is a gap between the existing design of the wheelchair and the ergonomic needs of the user.

Results: Data analysis showed significant variations in anthropometric dimensions among users. Based on these results, several design modifications were proposed, including adjustments to the seat width, backrest height, and footrest position. The designed prototype showed improvements in pressure distribution and sitting posture compared to the standard design.

Conclusion: Based on anthropometric data, wheelchair design adjustments are produced. The application of the anthropometric approach in wheelchair design adjustments succeeded in producing design criteria that are more in line with the ergonomic needs of elderly users.
