Flexor Dysfunction Following Unilateral Transient Ischemic Brain Injury Is Associated With Impaired Locomotor Rhythmicity, Kiril Tuntevski 2018 West Virginia University

Flexor Dysfunction Following Unilateral Transient Ischemic Brain Injury Is Associated With Impaired Locomotor Rhythmicity, Kiril Tuntevski

Graduate Theses, Dissertations, and Problem Reports

Functional motor deficits in hemiplegia after stroke are predominately associated with flexor muscle impairments in animal models of ischemic brain injury, as well as in clinical findings. Rehabilitative interventions often employ various means of retraining a maladapted central pattern generator for locomotion. Yet, holistic modeling of the central pattern generator, as well as applications of such studies, are currently scarce. Most modeling studies rely on cellular neural models of the intrinsic spinal connectivity governing ipsilateral flexor-extensor, as well as contralateral coupling inherent in the spinal cord. Models that attempt to capture the general behavior of motor neuronal populations, as well ...

Examining Upper Extremity Injuries In Male Baseball Players Between The Ages Of 14 To 22 Years Old

Chairperson: Melanie McGrath

The number of upper extremity injuries is increasing in advanced baseball (14 to 22 years old) at an alarming rate. The length of seasons, multiple leagues and the velocity of throwing in overhead sports are the most common causes of elbow and shoulder injuries. In addition, biomechanical variables also influence the risk of injury. Any alteration in range of motion (ROM) directly impacts the biomechanics of overhead activities, such as pitching ...

Matthew Vukovich

Objectives: The purpose of this study was to determine the effect of sports participation on cortical bone in the tibia. Methods: 53 female collegiate athletes (25 cross-country, 16 soccer, and 12 volleyball) and 20 inactive controls had the left distal 20% tibia scanned by pQCT. Cortical volumetric BMD (vBMD) was measured within the cortical shell at the anterior, posterior, medial, and lateral regions and standard deviations were calculated. Results: Total vBMD was greater in the control group (1161±5 mg/mm3) than each of the sports (p<0.05). Soccer players (1147±5 mg/mm3) had greater vBMD than volleyball players (1136±7 mg/mm3) (p<0.05), but similar to cross-country runners (1145±5 mg/mm3). Cortical thickness was greatest in soccer players (4.1±0.1 mm), while cross-country and control subjects (3.8±0.1 mm) had greater thickness than volleyball players (3.4±0.1 mm)(p<0.05). Periosteal circumference was greater in volleyball players (71±1.4 mm) than soccer, cross-country, and control subjects (68±0.9, 69±0.8, and 66±1 mm, respectively; all, p<0.05). vBMD variation within the cortical shell was greater among control subjects (70±6 mg/cm3) than each of the athlete groups, with soccer players having lower variation than cross country runners (within-in person SD 36±6 mg/cm3 and 54±5 mg/cm3 respectively; p<0.05). Conclusion: These results indicate bone geometry and distribution within the cortical shell of ...

A Graphene-Based Flexible Pressure Sensor With Applications To Plantar Pressure Measurement And Gait Analysis, Cunguang Lou, Shuo Wang, Tie Liang, Chenyao Pang, Lei Huang, Mingtao Run, Xiuling Liu

Open Access Publications by UMMS Authors

In the present study, we propose and develop a flexible pressure sensor based on the piezoresistive effect of multilayer graphene films on polyester textile. The pressure response results from the deformation of graphene conductive network structure and the changes in resistance. Here, we show that the graphene pressure sensor can achieve a sensitivity value of 0.012 kPa - 1 , the measurement range can be as high as 800 kPa, and the response time can reach to 50 ms. Subsequently, a stable in-shoe wireless plantar pressure measurement system is developed and dynamic pressure distribution is acquired in real-time. Overall, the graphene ...


Pannexins 1 And 3 In Skeletal Health And Osteoarthritis, Paxton M. Moon 2017 The University of Western Ontario

Pannexins 1 And 3 In Skeletal Health And Osteoarthritis, Paxton M. Moon

Electronic Thesis and Dissertation Repository

Osteoarthritis (OA) is a disease that gradually robs affected individuals of their mobility and places a substantial burden on health care systems and economies. OA results from pathological changes in bone, cartilage, synovium and supporting structures which are all essential to joint function. Cartilage degeneration, a hallmarking feature of OA, is an irreversible and untreatable consequence of these changes. Though the mechanisms underlying the initiation of cartilage breakdown remain unclear, joint injury and aging are risk factors. Pannexins (PANXs), a novel family of channel forming glycoproteins, have been suggested as important mediators of early OA. Therefore, my thesis tested the ...

Task Condition And Pupillometry, Mina Shojaeizadeh, Worcester Polytechnic Institute, John Rochford, Ping Chen

Eunice Kennedy Shriver Center Publications

While eye tracking is gaining popularity in IS research, pupillometry is relatively less explored in IS eye tracking studies. Research however suggests that pupillometry may serve as an excellent unobtrusive measure to study user information processing behavior. The Adaptive decision making theory asserts that task demand affects information processing behavior. Grounded in this theory, we argue that users’ pupillary responses will be different under different task conditions (task demand). We tested our assertion via an eye tracking laboratory experiment. Our results show that pupillary responses were significantly different under different task conditions.

Animal Science Publications

Despite well‐studied clinical manifestations, intracellular mechanisms of prolonged hyperthermic injury remain unclear, especially in skeletal muscle. Given muscle's large potential to impact systemic inflammation and metabolism, the response of muscle cells to heat‐mediated injury warrants further investigation. We have previously reported increased activation of NF‐κB signaling and increased NF‐κB and AP‐1‐driven transcripts in oxidative skeletal muscle following 12 h of heat stress. The purpose of this investigation was to examine early heat stress‐induced inflammatory signaling in skeletal muscle. We hypothesized that heat stress would increase NF‐κB and AP ...


Markerless Kinematics Of Pediatric Manual Wheelchair Mobility, Jacob Robert Rammer 2017 Marquette University

Markerless Kinematics Of Pediatric Manual Wheelchair Mobility, Jacob Robert Rammer

Dissertations (1934 -)

Pediatric manual wheelchair users face substantial risk of orthopaedic injury to the upper extremities, particularly the shoulders, during transition to wheelchair use and during growth and development. Propulsion strategy can influence mobility efficiency, activity participation, and quality of life. The current forefront of wheelchair biomechanics research includes translating findings from adult to pediatric populations, improving the quality and efficiency of care under constrained clinical funding, and understanding injury mechanisms and risk factors. Typically, clinicians evaluate wheelchair mobility using marker-based motion capture and instrumentation systems that are precise and accurate but also time-consuming, inconvenient, and expensive for repeated assessments. There is ...

University of Massachusetts Medical School Faculty Publications

Binge alcohol drinking, a behavior characterized by rapid repeated alcohol intake, is most prevalent in young adults and is a risk factor for excessive alcohol consumption and alcohol dependence. Although the alteration of synaptic plasticity is thought to contribute to this behavior, there is currently little evidence that this is the case. We used drinking in the dark (DID) as a model of binge alcohol drinking to assess its effects on spike timing-dependent plasticity (STDP) in medium spiny neurons (MSNs) of the core nucleus accumbens (NAc) by combining patch-clamp recordings with calcium imaging and optogenetics. After 2 weeks of daily ...


Inhibiting Axon Degeneration In A Mouse Model Of Acute Brain Injury Through Deletion Of Sarm1, Nils Henninger 2017 University of Massachusetts Medical School

Inhibiting Axon Degeneration In A Mouse Model Of Acute Brain Injury Through Deletion Of Sarm1, Nils Henninger

GSBS Dissertations and Theses

Traumatic brain injury (TBI) is a leading cause of disability worldwide. Annually, 150 to 200/1,000,000 people become disabled as a result of brain trauma. Axonal degeneration is a critical, early event following TBI of all severities but whether axon degeneration is a driver of TBI remains unclear. Molecular pathways underlying the pathology of TBI have not been defined and there is no efficacious treatment for TBI.

Despite this significant societal impact, surprisingly little is known about the molecular mechanisms that actively drive axon degeneration in any context and particularly following TBI. Although severe brain injury may cause ...

Trunk And Respiratory Motor Control In Typically Developing Children And Its Implications In Children With Chronic Spinal Cord Injury., Goutam Singh 2017 University of Louisville

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 ...

All PTHMS Faculty Publications

Background: Some normotensive patients can have a spike in resting systolic blood pressure (SBP) in response to acute neck pain. Applying the typical dosage of mobilization may potentially result in a sympatho-excitatory response, further increasing resting SBP. Therefore, there is a need to explore other dosage regimens that could result in a decrease in SBP.

Objectives: To compare the blood pressure (BP) and heart rate (HR) response of pain-free, normotensive adults when receiving unilateral posterior-to-anterior mobilization (PA) applied to the neck versus its corresponding placebo (PA-P).

Study design: Double-Blind, Randomized Clinical Trial.

Heat stress contributes to higher morbidity and mortality in humans and animals and is an agricultural economic challenge because it reduces livestock productivity. Redox balance and associated mitochondrial responses appear to play a central role in heat stress‐induced skeletal muscle pathology. We have previously reported increased oxidative stress and mitochondrial content in oxidative muscle following 12 h of heat stress. The purposes of this investigation were to characterize heat stress‐induced oxidative stress and changes in mitochondrial content and biogenic signaling in oxidative skeletal muscle. Crossbred gilts were randomly assigned to either thermal neutral (21°C; n = 8, control ...

FGF9 has complex and important roles in skeletal development and repair. We have previously observed that Fgf9 expression in osteoblasts (OBs) is regulated by G protein signaling and therefore the present study was done to determine whether OB-derived FGF9 was important in skeletal homeostasis. To directly test this idea, we deleted functional expression of Fgf9 gene in OBs using a 2.3 kb collagen type I promoter-driven Cre transgenic mouse line (Fgf9OB −/−). Both Fgf9 knockout (Fgf9OB −/−) and the Fgf9 floxed littermates (Fgf9fl/fl) mice were fully backcrossed and maintained in an FBV/N background. Three month old ...
