Abstract Details

2016, MS, University of Cincinnati, Engineering and Applied Science: Mechanical Engineering.
The rising population of elderly individuals in the United States of American creates a unique challenge to both the individual and the society due to the increase in risk of injuries to the elderly, drop in rate of productivity and rising healthcare costs. With aging, elderly individuals lose their independence in performing Activities of Daily Living (ADLs) due to muscle atrophy and therefore require assistance to perform activities like getting out of the bed, being able to rise from a chair and being able to use a restroom. These acts of assisted transferring have inherent risks of injury to both the elderly individual and the person providing assistance due to the unnatural and unbalanced biomechanics. Given the rising cost of supervision and the risk involved, a technological solution needs to be developed to help elderly individuals regain independence in performing daily activities. Exoskeletons are promising technological devices due to their ability to provide increased mobility. They have been designed for applications in the military, human spaceflight and for human rehabilitation. Understanding the biomechanics of movement is of prime importance while designing an exoskeleton to prevent injuries to the user. This work presents a standardized experimental evaluation of a sit-to-stand movement and computational musculoskeletal modeling to quantify the joint kinematics and joint moment. This work also compares biomechanical parameters characterizing the three strategies of sit-to-stand movement, namely fast, free and slow and how they affect the exoskeleton design process. Parameters thus obtained inform the actuator selection and fabrication of an active exoskeleton that supplements a user’s effort towards completion of a sit-to-stand movement.
