Impacts Of Methods And Pose On Performance Of Two Modern American Football Helmets, Ta’Quoris Newsome
Impacts Of Methods And Pose On Performance Of Two Modern American Football Helmets, Ta’Quoris Newsome
Honors Theses
The standardization of American football helmets began with the development of the National Operating Committee for Safety in Athletic Equipment (NOCSAE). The organization successfully developed a certification that quantifies a helmet’s ability to mitigate blunt force to prevent skull fractures; however, the ability to assure the same level of protection against concussion has been elusive. Regardless, The National Football League (NFL) and Virginia Tech University (VT) have developed blunt and rotational impact testing methodologies that aim to provide consumers with the effectiveness and safety of American football helmets through their respective ranking system. These ranking systems are intended to aid …
Validation Of An Inertial-Measurement-Unit System For Calculating Hip And Knee Flexion Angles During Gait, Joonsun Park
Validation Of An Inertial-Measurement-Unit System For Calculating Hip And Knee Flexion Angles During Gait, Joonsun Park
Master's Theses
Technological advances regarding Inertial Measurements Units (IMUs) have positioned this type of sensor as an alternative for camera-based motion capture. This study introduces a new IMU based system (IMUsys) to measure hip and knee flexion angles. PURPOSE: To validate the use of a five-sensor IMUsys for the measurement of knee and hip flexion angles during gait in adults and pediatrics at two different time points. METHODS: Bilateral hip and knee flexion patterns (LH, RH, LK, and RK) of twenty-two healthy participants (12 adults and 10 pediatric) between the ages of 8 – 35 years were investigated. Participants …
Effect Of Unilateral Lower-Limb Amputation On Intact Limb Biomechanics: A Systematic Review, Amanda Boyd
Effect Of Unilateral Lower-Limb Amputation On Intact Limb Biomechanics: A Systematic Review, Amanda Boyd
Master's Theses
The United States will perform 30,000-40,000 amputations this year (Ertl et al., 2019). As a common medical intervention, there is extensive research regarding rehabilitation strategies and post-operative care. Many studies have explored the effects of the affected limb and prosthetic intervention yet have neglected that of the contralateral limb (De Asha et al., 2014; Jones et al., 2006; Winter & Sienko, 1988). Studies have reported an increase in secondary musculoskeletal conditions among unilateral lower-limb amputees, particularly in the intact limb, indicating the need for additional research (Gailey et al., 2008). The purpose of this systematic review was to investigate the …
A Comparison Of Multipath And Conventional Neuromuscular Electrical Stimulation, Cody Brian Bremner
A Comparison Of Multipath And Conventional Neuromuscular Electrical Stimulation, Cody Brian Bremner
Dissertations
Neuromuscular electrical stimulation (NMES) is the use of an electrical current for the purpose of eliciting a muscular response, and these treatments are most often used clinically for the specific purpose of increasing quadriceps strength. It is commonly accepted that the effectiveness of NMES for this purpose is primarily determined by the NMES training intensity. However, spatially limited motor unit recruitment, fatigue and discomfort negatively impact NMES-induced torque, which subsequently reduces NMES training intensities. Due to the importance of NMES training intensity, a substantial amount of research has focused on strategies designed to increase NMES-induced torque production, as well as …
