Freezing Of Gait: Mechanisms, Mechanics, And Management, Peter S. Myers
Freezing Of Gait: Mechanisms, Mechanics, And Management, Peter S. Myers
Arts & Sciences Electronic Theses and Dissertations
Parkinson disease (PD) is a neurodegenerative disease with multiple motor and non-motor symptoms, including postural instability, gait impairments, and cognitive deficits. More than 50% of individuals with PD experience a symptom called freezing of gait (FOG), described as a transient inability to take another step forward. Individuals with PD who experience FOG (freezers) have further postural, gait, and cognitive impairments compared to individuals with PD without FOG (non-freezers). While degeneration of the dopaminergic neurons in the substantia nigra is accepted as the primary etiology of the disease, research shows that the disease has a global impact on the brain, accounting …
Performance Impact Of Different Lower-Limb Setup Positions In The Backstroke Swimming Start, Gordon E. Barkwell
Performance Impact Of Different Lower-Limb Setup Positions In The Backstroke Swimming Start, Gordon E. Barkwell
Electronic Thesis and Dissertation Repository
The performance impact of different knee extension angles in the setup position for a backstroke start was evaluated using an instrumented starting surface. Ten backstroke swimmers completed maximum-effort starts in each of two setup positions: one with the knees flexed, and one with the knees extended. The start handles and touchpad were instrumented with tri-axial force plates. Activity of major hip and knee extensors was measured using surface electromyography. Body position was recorded throughout the start using two high-speed cameras. There was no difference in time to 10 m between the two conditions, indicating there is likely no advantage in …

Ya Ching Hung EdD. and Aryeh Spingarn EP-C, CSCS, EIM-Level 2 Queens College, City University of New York Department of Family, Nutrition, and Exercise Sciences, Changes in Reach to Eat Movement Control After Intensive Training for Children with Unilateral Cerebral Palsy. Purpose: The current study compares the effects of an intervention on children with Congenital Hemiplegia during a simple eating task using kinematic analyses. Previous studies looked at simple bimanual tasks such as opening a drawer; no studies examined the effects of intensive training on unimanual reach, grasp, and eat movement control. Methods: 20 children with Unilateral Spastic Cerebral Palsy …

Background: Many organizations have introduced frameworks to reduce the incidence of football related concussions through proper equipment fitting, coach education, and alteration of tackling technique.
Purpose: The purpose of this study was to examine the effects of training in a vertical, head up tackling style on the number of head accelerations experienced while tackling in a controlled laboratory situation. The authors hypothesized that training in a head up tackling technique would reduce the severity of head acceleration experienced by participants.
Design: Controlled Laboratory Study.
Methods: Twenty-four participants (11.5 ± 0.6 years old, 60.5 ± 2.2 in, 110 ± 18.4 lbs.) …
