Spinal Cord Trauma: An Overview Of Normal Structure And Function, Primary And Secondary Mechanisms Of Injury, And Emerging Treatment Modalities, Daniel Morin
Senior Honors Theses
The structures of the spinal cord and vertebral column are designed to provide flexibility, while still providing ample protection for the spinal cord deep within. While it does offer remarkable protection against most routine trauma, the spinal cord is still vulnerable to high-force etiologies of trauma and may become damaged as a result. These events are referred to as primary injury. Following the initial injury, the body’s own physiological responses cause a cascade of deleterious effects, known as secondary injury. Secondary injury is a major therapeutic target in mitigating the effects of spinal cord injury (SCI), and much research is …

Introduction
Skillful object manipulation in various activities of daily living requires accurate and economical modulation of grip force, yet experimental studies investigating grip force using a prosthesis are lacking. The purpose of this study was to compare grip force output between two types of upper-limb prosthetic prehensors. We hypothesized a relationship between grip force output and the muscular tension needed to control the prehensor.
Materials and Methods
Ten able-bodied participants attempted to produce a static target grip force using a voluntary opening and voluntary closing prosthetic simulator and their anatomical hand. The target forces were 0.49 N, 4 N, and …
