Motion analysis and force plate technology were used to calculate the positive work, propulsive phase duration, and peak concentric power at the hip, knee, and ankle joints. Separate three-way …

Muscle-Specific Effective Mechanical Advantage And Joint Impulse In Weightlifting, Kristof Kipp, Chad Harris

Exercise Science Faculty Research and Publications

Lifting greater loads during weightlifting exercises may theoretically be achieved through increasing the magnitudes of net joint impulses or manipulating the joints’ effective mechanical advantage (EMA). The purpose of this study was to investigate muscle-specific EMA and joint impulse as well as impulse-momentum characteristics of the lifter-barbell system across a range of external loads during the execution of the clean. Collegiate-level weightlifters performed submaximal cleans at 65, 75, and 85% of their 1-repetition maximum (1-RM) while data from a motion analysis system and a force plate were used to calculate lifter-barbell system impulse and velocity, as well as net extensor …

1st Place Research Paper: The Effectiveness Of Yoga Therapy On An Adult, Post-Stroke Population: A Systematic Review, Baylor E. Hogan

Kevin and Tam Ross Undergraduate Research Prize

Objectives: The objectives of this paper are to (1) give a brief overview of stroke pathophysiology (2) outline yoga as a therapeutic strategy (3) present the current research on yoga rehabilitation for stroke (4) discuss the efficacy of yoga for chronic stroke.

Methods: Relevant terms were searched in PubMed, Web of Science, Academic OneFile, ScienceDirect, and Google Scholar electronic databases. Studies were excluded if they contained pediatric stroke, non-stroke neurological diseases, or subjects with comorbidities. Statistically significant data was extracted for the primary measures of nine trials.

Results: Four studies measured statistically significant outcomes (p<0.05). These included improvements in balance, independence, endurance, trait anxiety, fear of falling, self-efficacy, pain, strength, range of motion (ROM), activity, participation, and quality of life (QoL). Discussion: Lack of statistical significance in post-stroke depression (PSD) measures may be due to inadequate intervention length or a psychosocial cause of depression. Improvements in balance, flexibility, and strength from yoga participation permitted progress in disability and functionality. Finally, overall health-related quality of life (HRQL) is affected by the severity of mental disorders and physical disability. Yoga can have a positive effect in both domains and therefore, may improve HRQL.

The Comparison Of Dual-Tasking And Functional Fitness In Older Females, Anna Engler

Health, Human Performance and Recreation Undergraduate Honors Theses

Context: America’s aging population is growing faster than ever, resulting in increasing challenges for healthcare providers and caregivers. Over 33% of adults aged 65 and older fall annually, and falls are the number one cause of injury-related death in this age group. Assessing fall risk is difficult due to its multifactorial nature, but functional fitness serves as a proxy measure. Women are at a particularly high risk for fall-related injury due to lower bone mineral density and higher fall frequency when compared to males. Fear of falling is also a serious contributor to fall risk, and it affects up …

Prospective Assessment Of Return To Pre-Injured Levels Of Activity, Aaron D. Sciascia

Theses and Dissertations--Rehabilitation Sciences

Determining return to pre-injured levels of play following athletic injury can be challenging. The current practice of making decisions following rehabilitation as to whether or not a patient has returned to pre-injured levels of activity is potentially inaccurate because initial assessments of perceived physical capability are performed at a time of relative dysfunction or are based on patient recall. Since there is no true baseline of perceived and physical function prior to injury it is difficult to determine if an athlete has return to baseline or is simply better than they were at the time of injury. Therefore, it is …

The Effects Of External Focus Of Attention Exercise Rehabilitation On Dual Task Walking In Parkinson's Disease, Eric N. Beck

Theses and Dissertations (Comprehensive)

Parkinson’s disease impairs control of well-learned movements, and therefore, individuals with Parkinson’s disease are forced to walk with greater conscious control. This causes difficulties while walking and completing a secondary task simultaneously (dual tasking), in that distractions from conscious control of walking increase the risk of falls and injury. Although, attention-based exercise may be a potential avenue to decrease the demands associated with walking in Parkinson’s disease. For example, an external focus of attention (on manipulated objects) has been found to recruit the networks that are important for walking with little conscious control (automatic control networks). In contrast, an internal …

Body Composition Measurement In Children With Cerebral Palsy, Spina Bifida And Spinal Cord Injury: A Systematic Review Of The Literature, Michele L. Polfuss, Paula E. Papanek, Fallon Meyer-Wentland, Andrea Moosreiner, Lenore R. Wilkas, Kathleen J. Sawin

Exercise Science Faculty Research and Publications

Pediatric obesity is a major health concern that has an increased prevalence in children with special needs. In order to categorize a child’s weight, an assessment of body composition is needed. Obtaining an accurate body composition measurement in children with special needs has many challenges associated with it. This perplexing scenario limits the provider’s ability to screen, prevent and treat an abnormal weight status in this vulnerable population. This systematic review summarizes common methods of body composition measurements, their strengths and limitations and reviews the literature when measurements were used in children with cerebral palsy, spina bifida and spinal cord …

Upper Body Posture And Pain In Division I Female Volleyball And Softball Athletes, Brittany M. Plunkett Castilla

Dissertations and Theses

Participation in athletics is a popular pastime and form of entertainment. Children often begin to specialize in one sport at a young age in an effort to excel, which increases physical stress and the potential for injuries. Athletes participating in overhead sports are at increased risk of upper body chronic injuries, in part because the shoulder is an unstable hypermobile joint. Posture may also be affected in these athletes because of the demands placed on the upper body. The purpose of this study was to measure the upper body posture in a sample of Division I collegiate volleyball and softball …

Somatic Experiencing: Using Interoception And Proprioception As Core Elements Of Trauma Therapy, Peter Payne, Peter A. A. Levine, Mardi A. Crane-Godreau

Dartmouth Scholarship

Here we present a theory of human trauma and chronic stress, based on the practice of Somatic Experiencing(®) (SE), a form of trauma therapy that emphasizes guiding the client's attention to interoceptive, kinesthetic, and proprioceptive experience. SE™ claims that this style of inner attention, in addition to the use of kinesthetic and interoceptive imagery, can lead to the resolution of symptoms resulting from chronic and traumatic stress. This is accomplished through the completion of thwarted, biologically based, self-protective and defensive responses, and the discharge and regulation of excess autonomic arousal. We present this theory through a composite case study of …

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

Seton Hall University Dissertations and Theses (ETDs)

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 …

Direct Pro-Inflammatory Effects Of Prorenin On Microglia, Peng Shi, Justin L. Grobe, Fiona A. Desland, Guannan Zhou, Xiao Z. Shen, Zhiying Shan, Et. Al.

Department of Kinesiology and Integrative Physiology Publications

Neuroinflammation has been implicated in hypertension, and microglia have been proposed to play an important role in the progression of this disease. Here, we have studied whether microglia are activated within cardiovascular regulatory area(s) of the brain during hypertension, especially in high blood pressure that is associated with chronic activation of the renin-angiotensin-system. In addition, we determined whether prorenin, an essential component of the renin-angiotensin-system, exerts direct pro-inflammatory effects on these microglia. Our data indicate that two rodent models which display neurogenic hypertension and over activation of the renin-angiotensin-system in the brain (sRA mice and spontaneously hypertensive rats) exhibit microglial …

Movement-Based Embodied Contemplative Practices: Definitions And Paradigms, Laura Schmalzl, Mardi A. Crane-Godreau, Peter Payne

Dartmouth Scholarship

Over the past decades, cognitive neuroscience has witnessed a shift from predominantly disembodied and computational views of the mind, to more embodied and situated views of the mind. These postulate that mental functions cannot be fully understood without reference to the physical body and the environment in which they are experienced. Within the field of contemplative science, the directing of attention to bodily sensations has so far mainly been studied in the context of seated meditation and mindfulness practices. However, the cultivation of interoceptive, proprioceptive and kinesthetic awareness is also said to lie at the core of many movement-based contemplative …

Classifying Lower Extremity Muscle Fatigue During Walking Using Machine Learning And Inertial Sensors, Jian Zhang, Thurmon Lockhart, Rahul Soangra

Physical Therapy Faculty Articles and Research

Fatigue in lower extremity musculature is associated with decline in postural stability, motor performance and alters normal walking patterns in human subjects. Automated recognition of lower extremity muscle fatigue condition may be advantageous in early detection of fall and injury risks. Supervised machine learning methods such as Support Vector Machines (SVM) have been previously used for classifying healthy and pathological gait patterns and also for separating old and young gait patterns. In this study we explore the classification potential of SVM in recognition of gait patterns utilizing an inertial measurement unit associated with lower extremity muscular fatigue. Both kinematic and …

Injured Athletes' Preferences Regarding Source Of Emotional Support, Kristin Kutz

Honors Projects

Athletes often experience emotional distress as a result of an injury. Feelings of loss, decreased self-esteem, frustration, and anger are not uncommon. Athletic trainers (ATs) who work with injured athletes are focused on helping the progression of athletes' physical healing, but their role in helping athletes emotionally and psychologically is often unclear. There are twelve Athletic Training Education Competencies that the National Athletic Training Association requires to be taught to undergraduate AT students, one of them being psychosocial intervention and referral. However, little research has been done to define the exact role of ATs in this area, as well as …
