Introduction/Background: This topic focuses on the utilization of kinesio taping (KT) to assist with decreasing pain in the low back. According to Shipton, low back pain has gone up by more than 50% since 1990. These factors are attributed to smoking, obesity, sedentary occupations, and to low socioeconomic status.Globally, in 2016, it is said that low back pain contributed 57.6 years to disability and the prevalence peaks around the ages of 35-55 years according to the World Health Organization.

Purpose: The purpose of this literature review is to compare research articles between KT with physical therapy interventions as compared …

The Impact Of A Holistic Admissions Review Process In A Doctor Of Physical Therapy Program, Carrie Hawkins

Graduate Theses, Dissertations, and Capstones

Holistic admissions processes in doctor of physical therapy (DPT) education programs are perceived as a means to increasing the diversity of the profession. While previous research has correlated the Graduate Record Examination (GRE) to success on the National Physical Therapy Examination (NPTE) and the grade point average (GPA) to success in the program coursework, the impact of a holistic admissions process on the academic factors or on the demographics of the applicants offered admission has not been extensively studied for DPT education programs. This study was conducted to determine if the addition of a holistic application review process rubric to …

Sound Effects On Standing Postural Strategies In The Elderly Via Frequency Analysis Approach, Yun-Ju Lee, Chang-Hsu Chen, Chao-Che Wu, Yu-Jung Chen, Jing-Nong Liang

Physical Therapy Faculty Research

Sound and sound frequency could improve postural sway in the elderly. The power spectrum intervals of the center of pressure (COP) displacement are associated with different postural regulations, which could be revealed by frequency analysis. The aim of the study was to investigate the effects of sound on dual-tasking postural control and conduct frequency analysis to distinguish postural regulations in the elderly. Fifteen young and 15 older healthy participants were instructed to stand on a force platform and performed the Purdue Pegboard test while hearing 50 dB sounds with sound frequencies of 250 Hz, 1000 Hz, 4000 Hz, or no …

Acute Systemic Inflammation Reduces Both Carotid And Aortic Wave Reflection In Healthy Adults, Thessa Hilgenkamp, Elizabeth C. Schroeder, Wesley L. Lefferts, Bo Fernhall

Physical Therapy Faculty Research

Acute inflammation increases the risk of cardiac and cerebrovascular events, possibly related to alterations in the hemodynamic load. Wave reflection at the aorta and carotid provides insight into downstream vascular changes and hemodynamic load at the heart and brain. Acute inflammation has been suggested to reduce wave reflection via downstream vasodilation; however, this is not firmly established and has only been investigated at the aorta. We sought to explore the effect of acute inflammation on aortic and carotid hemodynamics in healthy, young adults. Pressure waveforms were collected via radial and carotid applanation tonometry in 23 adults (26 ± 4 years) …

Passive, Yet Not Inactive: Robotic Exoskeleton Walking Increases Cortical Activation Dependent On Task, Sue Peters, Shannon B. Lim, Dennis R. Louie, Chieh-Ling Yang, Janice J. Eng

Physical Therapy Publications

Background

Experimental designs using surrogate gait-like movements, such as in functional magnetic resonance imaging (MRI), cannot fully capture the cortical activation associated with overground gait. Overground gait in a robotic exoskeleton may be an ideal tool to generate controlled sensorimotor stimulation of gait conditions like ‘active’ (i.e. user moves with the device) and ‘passive’ (i.e. user is moved by the device) gait. To truly understand these neural mechanisms, functional near-infrared spectroscopy (fNIRS) would yield greater ecological validity. Thus, the aim of this experiment was to use fNIRS to delineate brain activation differences between ‘Active’ and ‘Passive’ overground gait …

Mediolateral Damping Of An Overhead Body Weight Support System Assists Stability During Treadmill Walking, M. Bannwart, S. L. Bayer, Niklas König Ignasiak, M. Bolliger, G. Rauter, C. A. Easthope

Physical Therapy Faculty Articles and Research

Background

Body weight support systems with three or more degrees of freedom (3-DoF) are permissive and safe environments that provide unloading and allow unrestricted movement in any direction. This enables training of walking and balance control at an early stage in rehabilitation. Transparent systems generate a support force vector that is near vertical at all positions in the workspace to only minimally interfere with natural movement patterns. Patients with impaired balance, however, may benefit from additional mediolateral support that can be adjusted according to their capacity. An elegant solution for providing balance support might be by rendering viscous damping along …

Young Adults Can Learn To Predict Unexpected Posterior Perturbations Using An Auditory Cue, Huaqing Liang, Tippawan Kaewmanee, Alexander S. Aruin

Physical Therapy Faculty Research

To reduce the effect of an expected postural perturbation, central nervous system uses anticipatory postural adjustments (APAs), which include the activation and inhibition of the postural muscles and a slight shift of the center-of-pressure (COP) position. The generation of APAs majorly relies on the availability of visual information, and is learned through past experience. Hence, such protective mechanism to maintain balance is not implemented when perturbation comes from one’s back unexpectedly. Our previous work showed that young adults could rely on an auditory cue only to generate APAs for a front perturbation similar to that when vision was available. So …

Older Adults Retain The Ability To Predict External Perturbations Using Auditory Cues Only, Huaqing Liang, Tippawan Kaewmanee, Alexander S. Aruin

Physical Therapy Faculty Research

To maintain balance and prevent destabilization, humans utilize anticipatory postural adjustments (APAs) prior to the postural perturbations based on predictions and past experience. APAs involve the activation and inhibition of the trunk and leg muscles and a shift of the center-of-pressure (COP) position. The generation of APAs majorly relies on the availability and accuracy of visual information. However, our previous work showed that young adults could rely on an auditory cue only to generate APAs for an external perturbation similar to that when the visual information was available. Older adults generally have diminished APAs and consequently diminished postural control when …

Effect Of Unilateral Lower-Limb Amputation On Intact Limb Biomechanics: A Systematic Review, Amanda Boyd

Master's Theses

The United States will perform 30,000-40,000 amputations this year (Ertl et al., 2019). As a common medical intervention, there is extensive research regarding rehabilitation strategies and post-operative care. Many studies have explored the effects of the affected limb and prosthetic intervention yet have neglected that of the contralateral limb (De Asha et al., 2014; Jones et al., 2006; Winter & Sienko, 1988). Studies have reported an increase in secondary musculoskeletal conditions among unilateral lower-limb amputees, particularly in the intact limb, indicating the need for additional research (Gailey et al., 2008). The purpose of this systematic review was to investigate the …

Using A Timed Motor Task To Predict One-Year Functional Decline In Amnestic Mild Cognitive Impairment, Sydney Y. Schaefer, Andrew Hooyman, Kevin Duff

Physical Therapy Faculty Articles and Research

Affordable, noninvasive methods of predicting functional decline are needed for individuals at risk for Alzheimer’s disease. This study tested whether a timed upper-extremity motor task predicted functional decline over one year in 79 adults diagnosed with amnestic mild cognitive impairment. Participants completed subjective and objective measures of daily functioning at baseline and one year later. Motor task performance and delayed memory were also evaluated at baseline. Motor task performance was a significant predictor of one-year follow-up daily functioning, improving model fits by 18– 35%. Thus, motor behavior has potential to be an affordable enrichment strategy that is sensitive to functional …

Pre-Stretching Of The Hamstrings Before Squatting Acutely Increases Biceps Femoris Thickness Without Impairing Exercise Performance, Thiago Barbosa Trindade, Leônidas Oliveira Neto, José Claudino Neto Pita, Vagner Deuel De Oliveira Tavares, Paulo Moreira Silva Dantas, Brad J. Schoenfeld, Jonato Prestes

Publications and Research

Background: Bilateral squat exercise is widely used in resistance training (RT) programs to increase lower limb strength and muscle mass, but this exercise does not result in significant hypertrophy of the hamstrings. It has been speculated that stretching between sets with a certain degree of tension results in muscle hypertrophy, while acute stretching could decrease performance during maximal contractions.

Objective: This study investigated the acute effects of hamstring stretching before bilateral squatting on muscle thickness (MT), electromyography (EMG), and total training volume (TTV) on exercise performance.

Methods: Fourteen resistance-trained young men, with ∼7.5 years of RT experience, performed the 10 …

Mini-Logger- A Wearable Inertial Measurement Unit (Imu) For Postural Sway Analysis, Michael Pollind, Rahul Soangra

Physical Therapy Faculty Articles and Research

Postural instability assessment is an important tool in fall risk analysis and for timely intervention of falls to reduce or prevent fall injuries. Traditionally fall risk is measured though postural sway assessment and is collected through forceplates by mapping Center of Pressure (COP) excursions or using motion analysis camera system for marker sway trajectories. However, both of these systems are expensive and lack portability to their usage in clinical environments. In this study, we developed a novel wearable low-cost MEMS inertial sensor and validated its usage for human postural sway assessment in standing posture with eyes open/closed, vibration/no vibration, and …

A Comparison Of Denoising Methods In Onset Determination In Medial Gastrocnemius Muscle Activations During Stance, Jian Zhang, Rahul Soangra, Thurmon Lockhart

Physical Therapy Faculty Articles and Research

One of the most basic pieces of information gained from dynamic electromyography is accurately defining muscle action and phase timing within the gait cycle. The human gait relies on selective timing and the intensity of appropriate muscle activations for stability, loading, and progression over the supporting foot during stance, and further to advance the limb in the swing phase. A common clinical practice is utilizing a low-pass filter to denoise integrated electromyogram (EMG) signals and to determine onset and cessation events using a predefined threshold. However, the accuracy of the defining period of significant muscle activations via EMG varies with …

Ca2+ Dependency Of Limb Muscle Fiber Contractile Mechanics In Young And Older Adults, Laura E. Teigen, Christopher W. Sundberg, Lauren J. Kelly, Sandra K. Hunter, Robert H. Fitts

Exercise Science Faculty Research and Publications

Age-induced declines in skeletal muscle contractile function have been attributed to multiple cellular factors, including lower peak force (P_o), decreased Ca²⁺ sensitivity, and reduced shortening velocity (V_o). However, changes in these cellular properties with aging remain unresolved, especially in older women, and the effect of submaximal Ca²⁺ on contractile function is unknown. Thus, we compared contractile properties of muscle fibers from 19 young (24 ± 3 yr; 8 women) and 21 older adults (77 ± 7 yr; 7 women) under maximal and submaximal Ca²⁺ and assessed the abundance of three proteins thought to …
