Biomechanics Of Teeth Alignment Using Clear Aligners With Various Attachment Shapes And Orientations, Egon Mamboleo
Biomechanics Of Teeth Alignment Using Clear Aligners With Various Attachment Shapes And Orientations, Egon Mamboleo
Graduate Theses, Dissertations, and Problem Reports (ETD)
Clear aligners have emerged as the most popular and preferred method of treatment for patients with orthodontic malocclusions. This is greatly due to the comfort and aesthetically appealing factors when compared to fixed appliances . Clear aligners are either thermoformed or 3D direct-printed plastics that apply biomechanical forces to the surface of teeth to trigger tooth movement and bone remodeling process. Common Class I malocclusions with mild or moderate crowding can be treated with clear aligners alone. However, treatment of Class II and Class III malocclusions that require extraction of permanent teeth or correction of severe rotations, and teeth extrusions …

Biologically – Plausible Load Feedback From Dynamically Scaled Robotic Model Insect Legs, William Zyhowski
Graduate Theses, Dissertations, and Problem Reports (ETD)
Researchers have been studying the mechanisms underlying animal motor control for many years using computational models and biomimetic robots. Since testing some theories in animals can be challenging, this approach can enable unique contributions to the field. An example of a system that benefits from this modeling and robotics approach is the campaniform sensillum (CS), a kind of sensory organ used to detect the loads exerted on an insect's legs. The CS on the leg are found in groups on high-stress areas of the exoskeleton and have a major influence on the adaptation of walking behavior. The challenge for studying …

A Solution For Overcoming Transradial Prosthetic Control Limitations With Additive Manufacturing And Modeling Techniques, Olivia Layne Santee
Graduate Theses, Dissertations, and Problem Reports (ETD)
Prosthetic limbs have aided in the restoration of both cosmetic and functional capabilities of the human hand; however, structural and control limitations hinder widespread adoption. One example of these limitations addressed in this study is the lack of wrist degrees of freedom (DOF) in robotic hands. Using the mechanical model-driven design, I developed a hand with cable-driven actuation of fingers and direct actuation of the wrist pronation-supination and flexion-extension DOFs. An inverse dynamic simulation determined torque requirements in common tasks manipulating a 1 kg mass with rotational speeds up to 60 deg/s, setting a minimum limitation of 0.76 Nm on …

Automated And Standardized Tools For Realistic, Generic Musculoskeletal Model Development, Trevor Rees Moon
Graduate Theses, Dissertations, and Problem Reports (ETD)
Human movement is an instinctive yet challenging task that involves complex interactions between the neuromusculoskeletal system and its interaction with the surrounding environment. One key obstacle in the understanding of human locomotion is the availability and validity of experimental data or computational models. Corresponding measurements describing the relationships of the nervous and musculoskeletal systems and their dynamics are highly variable. Likewise, computational models and musculoskeletal models in particular are vitally dependent on these measurements to define model behavior and mechanics. These measurements are often sparse and disparate due to unsystematic data collection containing variable methodologies and reporting conventions. To date, …

Evaluation Of Control Strategies For Overhead Work Using Electromyography Of Rotator Cuff Muscles, Hossein Motabar
Graduate Theses, Dissertations, and Problem Reports (ETD)
Work-related musculoskeletal disorders (MSDs) of shoulder have a significant impact on overall health and economics in the industrialized nations. Rotator cuff is the most frequently injured region in the shoulder complex. Overhead work is considered as one of the most predominant causes of rotator cuff injuries. The workers in construction, automotive, and aerospace industries are routinely exposed to overhead exertions. Elimination of overhead work is nearly impossible due to various task and technology constraints. Therefore, appropriate intervention strategies based on the engineering and administrative controls opt to be used to prevent the hazardous impact of overhead exertions. The objective of …
A Biomimetic Approach To Controlling Restorative Robotics, Matthew T. Boots
A Biomimetic Approach To Controlling Restorative Robotics, Matthew T. Boots
Graduate Theses, Dissertations, and Problem Reports (ETD)
Movement is the only way a person can interact with the world around them. When trauma to the neuromuscular systems disrupts the control of movement, quality of life suffers. To restore limb functionality, active robotic interventions and/or rehabilitation are required. Unfortunately, the primary obstacle in a person’s recovery is the limited robustness of the human-machine interfaces. Current systems rely on control approaches that rely on the person to learn how the system works instead of the system being more intuitive and working with the person naturally. My research goal is to design intuitive control mechanisms based on biological processes termed …
