The Effects Of Advancing Stages Of Pregnancy On Balance And Stair Locomotion In Healthy Females, Heather Vanderhoof
The Effects Of Advancing Stages Of Pregnancy On Balance And Stair Locomotion In Healthy Females, Heather Vanderhoof
Open Access Theses & Dissertations
Background: One in four females fall while pregnant, which may lead to injury, hospitalization, or birth complications. No empirical research has been conducted on single-limb support (SLS) balance or joint kinematics during stair locomotion in pregnant and postpartum females. The aim of this study was to quantify possible alterations to postural control and stair kinematics in advancing stages of pregnancy when compared to non-pregnant females. Methods: This cross-sectional study compared eighteen females, consisting of six non-pregnant controls, five 2nd trimester, four 3rd trimester, and three postpartum. Center of pressure excursion area data were obtained during static balance trials on a …
A Full Collegiate Volleyball Season Does Not Influence Jumping Or Landing Performance In Freshmen And Sophomore Players, Christian Noel Sanchez
A Full Collegiate Volleyball Season Does Not Influence Jumping Or Landing Performance In Freshmen And Sophomore Players, Christian Noel Sanchez
Open Access Theses & Dissertations
Knee injuries are devastating and typically experienced by athletes when performing jumping and landing tasks throughout a complete collegiate volleyball season. The purpose of this study was to examine changes in lower extremity strength, frontal plane knee angles and moments, jump performance during a countermovement and approach jump before and after a complete Division I collegiate volleyball season in female volleyball freshman and sophomores. Eight freshman/sophomore female collegiate volleyball players participated in the study. Lower extremity strength was assessed using an isokinetic dynamometer, kinematic and kinetic data were obtained through three-dimensional motion capture system and force platforms, respectively. Participants performed …
The Effects Of A 6-Week Controlled Whole-Body Vibration Training Program In Reducing Falls Risk Among Healthy Older Adults, Fabricio Saucedo Jr.
The Effects Of A 6-Week Controlled Whole-Body Vibration Training Program In Reducing Falls Risk Among Healthy Older Adults, Fabricio Saucedo Jr.
Open Access Theses & Dissertations
Falling is the second leading cause of accidental or injury-related death in the aging population worldwide and a leading cause of serious injury. Whole-body vibration (WBV) training has been implemented as a way to improve functional performance among the elderly and reduce the falls risk. The purposes of this study were: 1) examine to what extent a six-week course of WBV training reduced falls risk and improved fall outcomes in response to slips, and 2) examine whether the benefits of WBV training could be retained at least 2 months after the completion of the entire training session. A total of …
The Influence Of Over-Ground Versus Treadmill Walking On Gait Mechanics In Children With Autism Spectrum Disorder, Emily Ann Chavez
The Influence Of Over-Ground Versus Treadmill Walking On Gait Mechanics In Children With Autism Spectrum Disorder, Emily Ann Chavez
Open Access Theses & Dissertations
Treadmill (TM) walking may be a way to combat obesity and socio-behavioral barriers associated with children with Autism Spectrum disorder (ASD), though tripping-risk has not yet been assessed for this population through use of spatial-temporal gait analysis. The aim of this project/study was to examine spatial-temporal walking mechanics and lower extremity tripping descriptors between over ground (OG) and TM gait conditions in children with ASD compared to children with neurotypical development (NT). Kinematics data were obtained through tridimensional motion analysis where participants, 10 children with ASD and 9 age- and sexmatched NT controls, were outfitted with retroreflective markers on their …
