The Attentional Demands Of Ambulating With An Assistive Device In Older Adults With Alzheimer's Disease, Susan W. Hunter, M Montero-Odasso

Physical Therapy Publications

Ambulation with a mobility aid is a unique real-life situation of multi-tasking. These simultaneous motor tasks place increased demands on executive function in healthy young and older adults, but the demands have not been evaluated in people with Alzheimer's disease (AD). Mobility problems are common among adults with AD, leading to provision of a mobility aid to optimize independent activity. The study objectives were: (i) to determine the dual-task cost (DTC) associated with the use of a mobility aid in straight and complex path walking, and (ii) to evaluate the association between executive function and ambulation with a mobility aid …

Effect Of Whole-Body Vibration On Center-Of-Mass Movement During Standing In Children And Young Adults, Huaqing Liang, Matthew Beerse, Xiang Ke, Jianhua Wu

Physical Therapy Faculty Research

Whole body vibration (WBV) can affect postural control and muscular activation. The purpose of this study was to investigate the center-of-mass (COM) movement of children and young adults before, during, immediately after, and 5min after 40-s WBV in quiet standing. Fourteen young adults (mean age 24.5 years) and fourteen children (mean age 8.1 years) participated in the study. A full-body 35-marker set was placed on the participants and used to calculate COM. Forty-second standing trials were collected before, during, immediately after, and 5min after WBV with an frequency of 28Hz and an amplitude of <1mm. Two visual conditions were provided: eyes-open (EO) and eyes-closed (EC). COM variables included time-domain measures (average velocity, range, sway area and fractal dimension), frequency-domain measures (total power and median frequency), and detrended fluctuation analysis (DFA) scaling exponent in both anterior-posterior (AP) and medial-lateral (ML) directions. Results show that during WBV both children and adults increased average velocity and median frequency, but decreased range and the DFA scaling exponent. Immediately after WBV both groups increased the range, but showed pre-vibration values for most of the COM variables. Comparing to adults, children displayed a higher COM velocity, range, fractal dimension, and total power, but a lower DFA scaling exponent at all phases. The results suggest that both children and adults can quickly adapt their postural control system to WBV and maintain balance during and after vibration. Children display some adult-like postural control during and after WBV; however, their postural development continues into adolescence.

Differences In Interlimb Performance During A Repetitive Step Test In Older Adults, Harold L. Merriman, Kurt Jackson, Wesley Horn, Jake Jones, Evan Price, Jill Spicer

University of Dayton Doctor of Physical Therapy Annual Research Symposium

Each year, one out of three adults (younger than 65 years old) experiences a fall, resulting in fractures, head injuries, and even death. Falling is the leading cause of death from an injury and causes the greatest number of nonfatal injuries and hospital admissions for trauma. Since balance and muscle performance decrease as one ages, it is vitally important to assess these factors as part of a comprehensive strategy to monitor and predict fall risk. Previous data analysis of the Repetitive Step Test (RST) has shown that there is a correlation between subject performance and fall risk between non-fallers and …

Instrumented Measures Of Gait And Mobility Are Not Correlated With A History Of Falls Or Balance Confidence In Individuals With Multiple Sclerosis, Brandi Elking, Courtney Hasson, Emily Sanders, Kelsey Schlater

University of Dayton Doctor of Physical Therapy Annual Research Symposium

Individuals diagnosed with Multiple Sclerosis (MS) often have an increased risk of falling. Additionally, many also have a fear of falling that all can affect balance confidence. Recent advancements in wearable sensor technology have made it possible to assess certain aspects of gait and balance in the clinical setting that were not possible previously. The information collected by sensors may be useful for identifying specific factors that contribute to falls and balance confidence in those with MS which in turn could help enhance treatment approaches.

An Item-To-Total Analysis Of The Foot Posture Index, Amanda Pallija, Brian Bohman, Paige Prenger, Emely Richardson, Joaquin Barrios

University of Dayton Doctor of Physical Therapy Annual Research Symposium

The Foot Posture Index (FPI) is a screening tool used by clinicians to assess if the foot is pronated, neutral or supinated. It is intended to quantify foot position by assigning positive values to pronated attributes and negative values to supinated attributes. Three hindfoot and 3 forefoot attributes are scored. Although the FPI is valid and reliable, individual component scores may skew the composite score. Therefore, there lies a need to investigate the internal consistency of the FPI.

Acute Effects Of Walking On The Deformation Of Femoral Articular Cartilage, Jayson Mcclaren, Skyler Sudweeks

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background and Purpose: Knee osteoarthritis (OA) is characterized by a progressive loss of the articular cartilage, increasing the amount of friction in the joint, resulting in pain and decreases in mobility and function. Additionally, it has been demonstrated that frontal plane lower extremity (LE) malalignment (e.g., varus, valgus) is associated with onset and progression of OA. Previous studies showed that static loading of 50% body weight at the knee results in more cartilage deformation in those with knee OA compared to healthy controls. As walking produces forces in the knee that are 2-3 times body weight, it may result in …

Physiological Effects Of A Novel Fes Cycling Protocol On A 34-Year-Old Individual With Chronic Paraplegia, Kay Ann Simmons

Honors Theses

Background and Purpose: Individuals with spinal cord injury (SCI) are at a higher risk of sedentarism and the health risks that are associated with inactivity (Gorgey, Dolbow, Dolbow, Khalil & Gater, 2015). Because this population has limited exercise options due to paralysis, a new protocol of resistance-guided, high intensity interval training functional electrical stimulation (FES) cycling was developed to allow people with SCI to utilize their paralyzed legs as opposed to their overused arms. This new protocol is important as it provides an opportunity to restore body composition to a more favorable muscle to fat ratio decreasing obesity and increasing …

Trunk And Respiratory Motor Control In Typically Developing Children And Its Implications In Children With Chronic Spinal Cord Injury., Goutam Singh

Electronic Theses and Dissertations

Independent sitting is a major milestone and is also a prerequisite for optimal performance of activities of daily living (ADLs). Development of sitting posture control is a dynamic process involving control of degrees of freedom of head and trunk. Traditionally, trunk has been modeled as a single unit (segment). However, recent studies have suggested that it is made up multiple spinal units, controlled by a combination of trunk muscles. During typical development, posture control of trunk is different for different trunk segments. This motor development of trunk control is a complex process due to constant interaction between the nervous system …

Can Simple Postural Instructions Modify Running Forms In Recreational Runners, Casey Gray, Matthew Poggemiller, Ian Tracy

UNLV Theses, Dissertations, Professional Papers, and Capstones

Purpose/Hypothesis: Recent research suggests that alteration of trunk angle and foot strike pattern during running may result in beneficial changes that prevent running related injuries due to reduction in vertical ground reaction forces (vGRF). For example, running form emphasizing a forward trunk lean and a midfoot or forefoot strike pattern has been shown to be effective in reducing knee stress and the risks of other impact-related running injuries. In clinical practice however, it is currently unknown if simple postural cues given to runners can elicit motor learning that leads to modification of running form. The purpose of this study was …

Physical Therapy Faculty Research and Publications

Pulmonary ventilation (V̇_I) in awake and sleeping goats does not change when antagonists to several excitatory G protein-coupled receptors are dialyzed unilaterally into the ventral respiratory column (VRC). Concomitant changes in excitatory neuromodulators in the effluent mock cerebral spinal fluid (mCSF) suggest neuromodulatory compensation. Herein, we studied neuromodulatory compensation during dialysis of agonists to inhibitory G protein-coupled or ionotropic receptors into the VRC. Microtubules were implanted into the VRC of goats for dialysis of mCSF mixed with agonists to either μ-opioid (DAMGO) or GABA_A (muscimol) receptors. We found: (1) V̇_I decreased during unilateral but increased during …

Toward A Research Agenda For Oncology Physical Therapy, Lucinda Pfalzer, Nicole L. Stout, Shana Harrington, Mary Insana Fisher

Physical Therapy Faculty Publications

Research Round-up: Cancer survivors frequently experience cancer treatment–related functional impairments and disability. While a growing body of evidence supports the effectiveness of rehabilitation interventions for these individuals, there are significant gaps in the existing literature and no interdisciplinary agreement on the priorities for cancer rehabilitation research. In 2016, the Oncology Section revised its strategic plan and set an objective to create an oncology rehabilitation research agenda for the physical therapy (PT) profession. To achieve this goal, the scope of the agenda, a development and review process, and dissemination plan need to be developed.
