The Potential Role Of Weightlifting Training On The Biomechanics Of Patient Movements In The Prevention Of Back Injury, Michael Lee Callihan

Theses and Dissertations--Nursing

Back injury in nursing is a significant concern for the health of the worker, the costs to the healthcare system, and the safety of the patients. Current injury prevention measures include ergonomic adjustments to the work environment, the use of mechanical lifting equipment, policies to limit manual handling of patients, and the teaching of lifting techniques. These measures have been met with limited success in reducing injury rates. Little is known about whether changing the lifting biomechanics used in the healthcare setting can lower high injury rates across the profession.

The purposes of this dissertation were to: 1) identify the …

Design And Analysis Of A 3d-Printed, Thermoplastic Elastomer (Tpe) Spring Element For Use In Corrective Hand Orthotics, Kevin Thomas Richardson

Theses and Dissertations--Mechanical Engineering

This thesis proposes an algorithm that determine the geometry of 3D-printed, custom-designed spring element bands made of thermoplastic elastomer (TPE) for use in a wearable orthotic device to aid in the physical therapy of a human hand exhibiting spasticity after stroke. Each finger of the hand is modeled as a mechanical system consisting of a triple-rod pendulum with nonlinear stiffness at each joint and forces applied at the attachment point of each flexor muscle. The system is assumed quasi-static, which leads to a torque balance between the flexor tendons in the hand, joint stiffness and the design force applied to …
