The Effects Of Horseback Riding On The Gait Of Adolescents, Sarah L. Hayes Apr 2015

The Effects Of Horseback Riding On The Gait Of Adolescents, Sarah L. Hayes

Undergraduate Distinction Papers

ABSTRACT

The objective of this study was to investigate the changes that occur in the gait of a set of subjects after they ride a horse. Eleven riders with a developmental disability were selected and included in an experimental group and nineteen “typical” subjects or those without a developmental disability were included as a second comparison group. The length of time the subjects were able to remain standing in a tandem stance and in a one-legged stance without becoming unbalanced was measured and recorded. The stride length of the subject’s second and third step from heel to heel was also …


Take 2 Steps And Call Me In The Morning: Prescribing Physical Activity Through Primary Care, Emily Knight Apr 2015

Take 2 Steps And Call Me In The Morning: Prescribing Physical Activity Through Primary Care, Emily Knight

Electronic Thesis and Dissertation Repository

Objectives: Physical activity guidelines for older adults target high-intensity activities (i.e. increasing exercise), with less attention on low-intensity activities (i.e. reducing/interrupting sedentary behaviours) to improve health. Mobile health (mHealth) holds promise for engaging patients in self-management of chronic diseases. The purpose of this research was to prescribe physical activity of various intensities (i.e. sedentary through exercise) in primary care paired with mHealth for self-management.

Methods: 60 older adults (55-75yr) were randomly assigned to four groups: one control, and three receiving mHealth kits plus prescription for a specific intensity of physical activity (exercise, sedentary or both). Clinical measures (anthropometrics, …

Characterizing Knee Loading Patterns In People Post-Stroke, Stephanie Marrocco Mar 2015

Characterizing Knee Loading Patterns In People Post-Stroke, Stephanie Marrocco

Electronic Thesis and Dissertation Repository

Post-stroke temporal gait asymmetry (TGA) could cause excess loading of the non-paretic leg which may cause musculoskeletal (MSK) issues in the knee. This thesis investigated knee loading during gait and its relationship to TGA post-stroke. Methods: Gait analysis was conducted in nine people post-stroke. Gait was classified as symmetric (TGS) or asymmetric and external knee adduction (KAM) and flexion moments (KFM) were calculated. Participants were compared to healthy older adults (n=109) on KAM and KFM. The proportion of individuals with increased loading was compared between the TGS and TGA groups. Results: Six and four participants exhibited increased loading …


Effect Of Dual Tasking On Walking Over Even And Uneven Surfaces In Functionally Independent Community Older Adults, Olajide L. Kolawole Mar 2015

Effect Of Dual Tasking On Walking Over Even And Uneven Surfaces In Functionally Independent Community Older Adults, Olajide L. Kolawole

Olajide L Kolawole

While several studies have reported a decrement in performance by older adults while walking and concurrently performing a dual task on even surfaces, to date the effects of dual tasking while walking on uneven surfaces commonly found in the community has received less attention. Thus, we sought to test the hypothesis that an incremental decrement in gait parameters will be observed, when walking on an uneven versus an even surface and furthermore, that this decrement would be dependent upon the concurrent performance of a secondary cognitive and/or motor task in functionally independent-living-community older adults. Dynamic Gait Index assessed the subject’s …


Validation Of A 5k Age And Weight Run Handicap Model, Paul M. Vanderburgh, Lloyd L. Laubach Mar 2015

Validation Of A 5k Age And Weight Run Handicap Model, Paul M. Vanderburgh, Lloyd L. Laubach

Paul M. Vanderburgh

Though increasing age and body weight (BW) have been widely known to be associated with slower distance run times, the common convention in 5K road races is to categorize competitors by age and, sometimes, BW. This has the disadvantage of assigning only small numbers of competitors to age categories and giving advantage to runners close to the minimum age or BW values allowable. Using recent advances in the modeling of distance run performance by BW combined with empirical evidence quantifying the independent effect of age on cardiovascular endurance, we previously published the derivation of the 5K Handicap (5KH), an age …


Body Weight Penalties In The Physical Fitness Tests Of The Army, Air Force, And Navy, Paul M. Vanderburgh, Todd A. Crowder Mar 2015

Body Weight Penalties In The Physical Fitness Tests Of The Army, Air Force, And Navy, Paul M. Vanderburgh, Todd A. Crowder

Paul M. Vanderburgh

Recent research has empirically documented a consistent penalty against heavier service members for events identical or similar to those in the physical fitness tests of the Army, Air Force, and Navy. These penalties, not related to body fatness, are based on biological scaling models and have a physiologic basis. Using hypothetical cases, we quantified the penalties for males, 60 vs. 90 kg body weight, and females, 45 vs. 75 kg, to be 15-20% for the fitness tests of these three services. Such penalties alone can adversely impact awards and promotions for heavier service members. To deal equitably with these penalties …


Body Mass Bias In A Competition Of Muscle Strength And Aerobic Power, Paul M. Vanderburgh, Lloyd L. Laubach Mar 2015

Body Mass Bias In A Competition Of Muscle Strength And Aerobic Power, Paul M. Vanderburgh, Lloyd L. Laubach

Paul M. Vanderburgh

Recently, a fitness competition called the Pump and Run (PR) has been popularized. Composed of 2 events, a 5-km road race time (RT) in seconds and a maximal-repetition bench press (BPR) with resistance based on a percentage of body mass (M), the final score (RTadj) equals RT - 30(BPR). From published findings, the authors hypothesized that the PR would impose a bias against heavier competitors. Furthermore, the potential for age bias in this event has not been evaluated. Therefore, the purpose of this study was to investigate M and age bias in the PR for men and women. For 74 …


Correction Factors For Body Mass In Military Physical Fitness Tests, Paul M. Vanderburgh Mar 2015

Correction Factors For Body Mass In Military Physical Fitness Tests, Paul M. Vanderburgh

Paul M. Vanderburgh

Recent research findings combined with the theoretical laws of biological similarity make the compelling case that all physical fitness test items for the Army, Air Force, and Navy impose a 15-20% physiologic bias against heavier, not fatter, men and women. Using the published findings that actual scores of muscle and aerobic endurance scale by body mass raised to the 1/3 power, correction factor tables were developed. This correction factor can be multiplied by one’s actual score (e.g., push-ups, sit-ups, abdominal crunches, or curl-ups repetitions or distance run time) to yield adjusted scores that are free of body mass bias. These …


Derivation Of An Age And Weight Handicap For The 5k Run, Paul M. Vanderburgh, Lloyd L. Laubach Mar 2015

Derivation Of An Age And Weight Handicap For The 5k Run, Paul M. Vanderburgh, Lloyd L. Laubach

Paul M. Vanderburgh

The adverse effect of increasing age and/or body weight on distance run performance has been well documented. Accordingly, nearly all five kilometer (5K) road races employ age categories and, sometimes, a heavier body weight classification. Problems with such conventions include small numbers of runners within older age categories and the advantage given to the lightest runners within each weight category. We developed a 5K Handicap (5KH), a model that calculates an adjusted run time based on the inputs of actual 5K run time, age, and body weight for men and women. This adjusted time, then, can be compared between runners …


Occupational Relevance And Body Mass Bias In Military Physical Fitness Tests, Paul M. Vanderburgh Mar 2015

Occupational Relevance And Body Mass Bias In Military Physical Fitness Tests, Paul M. Vanderburgh

Paul M. Vanderburgh

Recent evidence makes a compelling case that U.S. Army, Navy, and Air Force health-related physical fitness tests penalize larger, not just fatter, service members. As a result, they tend to receive lower scores than their lighter counterparts, the magnitude of which can be explained by biological scaling laws. Larger personnel, on the other hand, tend to be better performers of work-related fitness tasks such as load carriage, heavy lifting and materiel handling. This has been explained by empirical evidence that lean body mass and lean body mass to dead mass ratio (dead mass = fat mass and external load to …


Body Mass Bias In Exercise Physiology, Paul Vanderburgh Mar 2015

Body Mass Bias In Exercise Physiology, Paul Vanderburgh

Paul M. Vanderburgh

In certain physically demanding occupations, especially the military, body mass bias has substantive implications. Work physiologists have determined that despite body mass bias in the common military physical fitness tests, the larger service members were often better performers of the physically demanding occupational tasks (Bilzon et al., 2002; Lyons et al., 2005; Rayson et al., 2000). That is, they could carry more, more easily evacuate casualties, and better engage in heavy materiel handling. Yet, the smaller personnel were achieving better scores on the physical fitness tests, the results of which have significant promotion and advancement implications (Vanderburgh & Mahar , …


Load Carriage Distance Run And Pushups Tests: No Body Mass Bias And Occupationally Relevant, Paul M. Vanderburgh, Nicholas S. Mickley, Philip A. Anloague, Kimber Lucius Mar 2015

Load Carriage Distance Run And Pushups Tests: No Body Mass Bias And Occupationally Relevant, Paul M. Vanderburgh, Nicholas S. Mickley, Philip A. Anloague, Kimber Lucius

Paul M. Vanderburgh

Recent research has demonstrated body mass (M) bias in military physical fi tness tests favoring lighter, not just leaner, service members. Mathematical modeling predicts that a distance run carrying a backpack of 30 lbs would eliminate M-bias. The purpose of this study was to empirically test this prediction for the U.S. Army push-ups and 2-mile run tests. Two tests were performed for both events for each of 56 university Reserve Offi cer Training Corps male cadets: with (loaded) and without backpack (unloaded). Results indicated signifi cant M-bias in the unloaded and no M-bias in the loaded condition for both events. …


Validity Of Boston Marathon Qualifying Times, Paul M. Vanderburgh Mar 2015

Validity Of Boston Marathon Qualifying Times, Paul M. Vanderburgh

Paul M. Vanderburgh

Purpose: To assess the validity of Boston Marathon qualifying (BMQ) standards for men and women. Methods: Percent differences between BMQ and current world records (WR) by sex and age group were computed. WR was chosen as the criterion comparison because it is not confounded by intensity, body composition, lifestyle, or environmental factors. A consistent difference across age groups would indicate an appropriate slope of the age-vs-BMQ curve. Inconsistent differences were corrected by adjusting BMQ standards to achieve a uniform percentage difference from WR. Results: BMQ standards for men were consistently ~50% slower than WR (mean 51.5% ± 1.4%, range 49.6–54.4%), …


Reliance On Auditory Feedback In Children With Childhood Apraxia Of Speech, Jenya Iuzzini-Seigel, Tiffany P. Hogan, Anthony J. Guarino, Jordan R. Green Mar 2015

Reliance On Auditory Feedback In Children With Childhood Apraxia Of Speech, Jenya Iuzzini-Seigel, Tiffany P. Hogan, Anthony J. Guarino, Jordan R. Green

Speech Pathology and Audiology Faculty Research and Publications

Children with childhood apraxia of speech (CAS) have been hypothesized to continuously monitor their speech through auditory feedback to minimize speech errors. We used an auditory masking paradigm to determine the effect of attenuating auditory feedback on speech in 30 children: 9 with CAS, 10 with speech delay, and 11 with typical development. The masking only affected the speech of children with CAS as measured by voice onset time and vowel space area. These findings provide preliminary support for greater reliance on auditory feedback among children with CAS.

Learning outcomes: Readers of this article should be able to (i) …


The Importance Of Managing Psychosocial Health: A Case Study, Mary Insana Fisher, Harold L. Merriman Feb 2015

The Importance Of Managing Psychosocial Health: A Case Study, Mary Insana Fisher, Harold L. Merriman

Harold L. Merriman

Managing the physical aspects of lymphedema requires an individual to be committed to daily treatment of this chronic condition. Performing manual lymph drainage, using compression bandaging or compression garments, exercising, and caring for the skin all take time and a high level of dedication. This commitment to self-care can be emotionally and psychologically exhausting. When coupled with other emotional stressors in a patient’s life, successful treatment of lymphedema is challenging. We present a case demonstrating how the physical and psychological aspects of care interplay, and, when well-managed, can positively affect the outcome.


Contributions Of Body Fat And Effort In The 5k Run: Age And Body Weight Handicap, Anne R. Crecelius, Paul M. Vanderburgh, Lloyd L. Laubach Feb 2015

Contributions Of Body Fat And Effort In The 5k Run: Age And Body Weight Handicap, Anne R. Crecelius, Paul M. Vanderburgh, Lloyd L. Laubach

Paul M. Vanderburgh

The 5K handicap (5KH), designed to eliminate the body weight (BW) and age biases inherent in the 5K run time (RT), yields an adjusted RT (RTadj) that can be compared between runners of different BW and age. As hypothesized in a validation study, however, not all BW bias may be removed, because of the influences of body fatness (BF) and effort (run speed; essentially the inverse as measured by rating of perceived exertion (RPE)). This study's purpose was to determine the effects of BF and RPE on BW bias in the 5KH. For 99 male runners in a regional 5K …

Purpose

To review measurement concepts inherent in pediatric dexterity testing and introduce concepts that are infrequently measured or novel as exemplified with two assessment tools.

Methods

Measurement concepts included in common assessment tools are introduced first. We then describe seldom measured and novel concepts embedded in two instruments; …


Understanding Atp-Mediated Vasodilatation In Humans, Anne R. Crecelius, Frank A. Dinenno Jan 2015

Understanding Atp-Mediated Vasodilatation In Humans, Anne R. Crecelius, Frank A. Dinenno

Anne R. Crecelius

Negative results, cynicism, the piecing together of puzzles and integrating physiology with experimental approaches are all part of the inspiring and meandering journey on the path to understand ATP-mediated vasodilatation. While it is satisfying to be "right" as scientists, we know sometimes the most important progress occurs when data are surprising or contrary to our original hypothesis. The pursuit of explanations for unexpected findings often leads to the best advancements. The story of how our laboratory came to investigate the underlying vasodilatator pathways of adenosine triphosphate (ATP) is an example of such a path to our current understanding.

Reactive Hyperemia Occurs Via Activation Of Inwardly-Rectifying Potassium Channels And Na+/K+-Atpase In Humans, Anne R. Crecelius, Jennifer C. Richards, Gary J. Luckasen, Dennis G. Larson, Frank A. Dinenno Jan 2015

Reactive Hyperemia Occurs Via Activation Of Inwardly-Rectifying Potassium Channels And Na+/K+-Atpase In Humans, Anne R. Crecelius, Jennifer C. Richards, Gary J. Luckasen, Dennis G. Larson, Frank A. Dinenno

Anne R. Crecelius

Rationale: Reactive hyperemia (RH) in the forearm circulation is an important marker of cardiovascular health, yet the underlying vasodilator signaling pathways are controversial and thus remain unclear. Objective: We hypothesized that RH occurs via activation of inwardly rectifying potassium (KIR) channels and Na+/K+-ATPase and is largely independent of the combined production of the endothelial autocoids nitric oxide (NO) and prostaglandins in young healthy humans. Methods and Results: In 24 (23±1 years) subjects, we performed RH trials by measuring forearm blood flow (FBF; venous occlusion plethysmography) after 5 minutes of arterial occlusion. In protocol 1, we studied 2 groups of 8 …

Research outputs 2014 to 2021

Background: There is a wealth of evidence detailing gray matter degeneration and loss of cognitive function over time in individuals with Huntington's disease (HD). Efforts to attenuate disease-related brain and cognitive changes have been unsuccessful to date. Multidisciplinary rehabilitation, comprising motor and cognitive intervention, has been shown to positively impact on functional capacity, depression, quality of life and some aspects of cognition in individuals with HD. This exploratory study aimed to evaluate, for the first time, whether multidisciplinary rehabilitation can slow further deterioration of disease-related brain changes and related cognitive deficits in individuals with manifest HD. Methods: Fifteen participants who …

Physical Therapy Faculty Articles and Research

Objective

This study was undertaken to better understand the high variability in response seen when treating human subjects with restorative therapies poststroke. Preclinical studies suggest that neural function, neural injury, and clinical status each influence treatment gains; therefore, the current study hypothesized that a multivariate approach incorporating these 3 measures would have the greatest predictive value.

Methods

Patients 3 to 6 months poststroke underwent a battery of assessments before receiving 3 weeks of standardized upper extremity robotic therapy. Candidate predictors included measures of brain injury (including to gray and white matter), neural function (cortical function and cortical connectivity), and clinical …


Early Intervention Of Parent-Infant Interactions In Preterm Infants: A Systematic Review, Stacey Osborne Jan 2015

Early Intervention Of Parent-Infant Interactions In Preterm Infants: A Systematic Review, Stacey Osborne

Theses : Honours

Every year approximately 15 million babies are born preterm. These infants are at an increased risk of language, and other developmental delays due to their immature brain development and higher incidence of brain abnormalities. They also have poorer health outcomes in the early stages of life which may go on to hinder successful parent-infant interactions. Successful parent-infant interactions are important for infant developmental outcomes such as language, cognition and behaviour. While interventions targeting the promotion of positive interactions have been found to have positive effects in a number of populations to date, interactions involving preterm infants have not been explored. …

The Capstone Project is focused on communicating, influencing and educating other health care professionals regarding the role of occupational therapy in the future model of primary care delivery initiated by the adoption of the Affordable Care Act and the Triple Aim Initiative. Currently, primary care, the largest health care platform in United States, is not inclusive of occupational therapy services. Occupational therapists have the scope, knowledge and understanding to be part of the redesigned team model of primary care. Educating those currently working in primary care about adding occupational therapy services can have a significant impact on the profession of …


Biomechanical Analysis Of Race Walking Compared To Normal Walking And Running Gait, Jaclyn D. Norberg Jan 2015

Biomechanical Analysis Of Race Walking Compared To Normal Walking And Running Gait, Jaclyn D. Norberg

Theses and Dissertations--Kinesiology and Health Promotion

Human locomotion is phenomenon that is extraordinarily complex. It is evident that a complete description of locomotion involves consideration of kinematics, kinetics, and muscle activity of the extremities in all of their various movements. Race walking (RW) is a form of upright locomotion that differs from normal walking and running by its form dictated by the International Amateur Athletics Federation (IAAF). Despite the similarities to both normal walking (NW) and running (RU), RW has not been the subject of equally intensive investigations.

This study explores the comprehensive biomechanics of race walking and how it compares to NW and RU. A …
