The Effects Of Abdominal Training On Postural Control, Lower Extremity Kinematics, Kinetics, And Muscle Activation, Matthew J. Gage Aug 2009

The Effects Of Abdominal Training On Postural Control, Lower Extremity Kinematics, Kinetics, And Muscle Activation, Matthew J. Gage

Theses and Dissertations

Context: Abdominal training may decrease the risk of lower extremity injuries through improved balance and postural control. Objective: To determine the effect of an eight-week abdominal-training program on center of pressure, lower extremity joint angles, and abdominal muscle activation during a single-leg drop landing. The effects of abdominal training on abdominal muscle thickness was assessed. Design: A cohort research design. Setting: Research laboratory. Other Participants: Sixty healthy physically active college-aged students participated. They were divided into three groups: Control, Chronic ankle instability (CAI), and Healthy. Nineteen Control (age = 22.0 ± 2.72 yrs, mass = 74.1 ± 13.8 kg, height ...


Reliability Of Sixteen Balance Tests In Individuals With Down Syndrome, Romina Villamonte Jul 2009

Reliability Of Sixteen Balance Tests In Individuals With Down Syndrome, Romina Villamonte

Theses and Dissertations

The purpose of this study was to determine the reliability of sixteen balance tests in individuals with Down syndrome (DS). The following tests were performed on 21 participants with DS, aged 5-31 years of age; standing test on firm and soft surfaces with the eyes opened and closed, a balance subset of the Bruininks-Oseretsky test, full turn, timed-up-and-go test, forward reach, and sit-to-stand. Each participant completed all 16 assessments twice on one day and then again on a subsequent day for a total of four trials. Seven tests had reliability coefficients greater than 0.55; one-leg stand on floor (0 ...


Does Practice Of Multi-Directional Stepping With Auditory Stimulation Improve Movement Performance In Patients With Parkinson's Disease, Zahra Kadivar Jan 2009

Does Practice Of Multi-Directional Stepping With Auditory Stimulation Improve Movement Performance In Patients With Parkinson's Disease, Zahra Kadivar

LSU Doctoral Dissertations

Parkinson’s disease (PD) is a debilitating neurodegenerative disorder causing many physical limitations. Rhythmic auditory stimulation (RAS) influences motor complications not alleviated by medicine and has been used to modify straight line walking in this population. However, motor complications are exacerbated during more complex movements including those involving direction changes. Thus immediate RAS effects on direction switch duration (DSD) and other kinematic measures during a multi-directional step task were investigated in PD patients. Long term RAS application was also explored by evaluating functional gait and balance and kinematic step measures before and after 6 weeks of multi-directional stepping either with ...


Identification Of Falls Risk Factors In Community-Dwelling Older Adults: Validation Of The Comprehensive Falls Risk Screening Instrument, Jennifer Marie Fabre Jan 2009

Identification Of Falls Risk Factors In Community-Dwelling Older Adults: Validation Of The Comprehensive Falls Risk Screening Instrument, Jennifer Marie Fabre

LSU Doctoral Dissertations

Identifying risk factors and those at risk for falls is necessary. The first purpose of the dissertation was to validate the Comprehensive Falls Risk Screening Instrument (CFRSI) that weights falls risk factors and includes the subscale scores of history, physical, vision, medication, and environment, and a total falls risk score. The CFRSI total falls risk score was compared to subscale scores, physical activity, physical function, health-related quality of life (HRQL), and history of falls (Study 1). The second purpose of the dissertation was to determine associations between the CFRSI total falls risk score, race, education, and income (Study 2). Data ...
