A biomechanical posture analysis by using ergonomic and kinematic approach during water liftingin the rural area of jhargram, west bengal

Abstract

Every individual works and their work situation make social status, health status, development and self-efficient. Good postures while working is the wonderful way to have productive and healthy work-life, therefore no more using heavy loads and harmful postures. In today’s life, with having competitive life, work containing repetitive movements with a certain duration are very well monitored. And about to reduce the number of risks as much as possible. Since the risk is known. But still sometimes smaller loads can affect our body and put it at risk. Because of this project it was found if any harmful postures are there or not. If it is there, then it may turn out to be a huge risk of injury. The purpose of this project was to investigate the biomechanical concepts and ergonomics concepts in women’s body while pulling a load (fetching water) a bucket of water out of the well by using rope in a rural area. This work is their daily life work. This work was done by identifying the present ergonomic state in the village using the ergonomic evaluation method. This study has approaches using ergonomics theories and some research questions are need to verify. This study was also done using human motion analysis. Analysing the joint using trajectories to know that how much time a joint is staying in static position and if joint is moving then what will be their speed. For ergonomic method, we have used RULA and REBA. And for analysing method, KINOVEA software were used to evaluate joints' angular and linear motion. The angular displacement will show the angles between the joints during work. The risk assessment is known from the RULA, REBA scores and it will reveal the exposure level of risk by score. Other than ergonomics and mechanical processes, to know the health information and risk information a personal information record is needed and a standard questionnaire for musculoskeletal disorder has to go through. And some interviews were taken to conclusion of musculoskeletal disorders. Having an ergonomic approach and a mechanical approach can lead us to understand biomechanical understanding. So, biomechanical work has to be done. It finally cleared that the loading understanding and the relation that helps to see musculoskeletal disorder while working.
