Mechanical Deviations And Verbal-Cue Altered Gait In The Femoroacetabular Impingement Syndrome Population, Walter Menke
Mechanical Deviations And Verbal-Cue Altered Gait In The Femoroacetabular Impingement Syndrome Population, Walter Menke
Theses and Dissertations--Kinesiology and Health Promotion
Femoroacetabular impingement syndrome (FAIS) is an abnormal physical hip morphology that causes functional changes and pain during gait. Mechanical gait differences in this population require further biomechanical investigation to elucidate characteristics unique to this group. Fixed speed gait trials were performed on force plates and analyzed in addition to isokinetic strength testing to find a multitude of biomechanical variables including joint moment, joint power, joint work, and peak joint angle. This work has discovered evidence of muscular deficits at the hip, specifically hip extension, as well as knee joint power contributions to gait when compared to controls. These findings suggest …
Chronic Ankle Instability And Aging, Kyle B. Kosik
Chronic Ankle Instability And Aging, Kyle B. Kosik
Theses and Dissertations--Rehabilitation Sciences
Lateral ankle sprains are the most common musculoskeletal injury among the general population and U.S. military personnel. Despite the common perception of being a minor injury, at least 1 out of 3 individuals with a previous ankle sprain will develop chronic ankle instability (CAI). This clinical phenomenon creates a significant barrier for patients to return to their prior level of physical function. Specifically, CAI is associated with reductions in physical activity level, leading to decreases in lower health-related quality of life and increase risk of developing of post-traumatic ankle osteoarthritis. Current evidence has largely focused on characterizing the mechanical and …
The Effect Of Tactical Tasks And Gear On Muscle Activation Of Swat Officers, Jason M. Keeler
The Effect Of Tactical Tasks And Gear On Muscle Activation Of Swat Officers, Jason M. Keeler
Theses and Dissertations--Kinesiology and Health Promotion
Special Weapons and Tactics (SWAT) officers constitute a subgroup of specialized law enforcement officers that perform a variety of tactical operations while wearing approximately 40 kg of tactical gear. Lower back pain is a prevalent musculoskeletal injury suffered by SWAT officers. Tactical gear places significant stress on the lower back. Thus, it is important to quantify the effect that tactical gear has on muscle activation levels of torso musculature while performing occupational tasks. Electromyography was evaluated on 20 male subjects (age: 34.7±4.5 yr.; height: 1.79±.10 m; body mass: 91.53±17.32 kg; mass of gear: 13.82±1.90 kg) while performing four tactical tasks …
