The Impact Of Semantics And Syntax On Lexical Retrieval In Individuals With Aphasia, Marta M. Korytkowska

Dissertations, Theses, and Capstone Projects

Nearly all people with aphasia (PWA) report difficulty with lexical retrieval (i.e., anomia). While there are several tasks used to measure lexical retrieval, each poses different degrees and types of challenges. For example, some studies have found that PWA performance varies depending on the type of lexical retrieval task. The tasks that have been used include lexical retrieval in isolation tasks (such as picture-naming), lexical retrieval in sentence level tasks (such as narration tasks), and lexical retrieval in sentence-completion tasks. Some studies have found no differences between the accuracy of lexical retrieval in isolation and at the sentence level (e.g., …

The Effects Of Music Therapy On Elderly Adults With Dementia, Jeante J. Jackson

Dissertations, Theses, and Capstone Projects

As people age, the brain is more susceptible to changes that diminish cognitive function. In recent years neuroscience has found convergent evidence between music therapy and brain architecture, as it has shown the generation of new connections in the brain or a reorganization and possible strengthening of existing connections already in the brain. However, the literature regarding music training’s effects on executive control, selective attention, and speech processing is lacking particularly when it comes to older populations.

This study investigated Verbal Working Memory, Visuospatial Attention and Task Initiation, and Auditory Selective Attention in a 91-year-old adult (B.P.) diagnosed with dementia. …

Creating An Interactive Virtual-Reality Game As A Method For Vestibular Rehabilitation, Jessica Kaganskiy

Dissertations, Theses, and Capstone Projects

Virtual reality is an innovative form of technology that has been used more and more in vestibular rehabilitation therapy programs for individuals with chronic balance problems. Blender and Unity game engines were used to create a 3D interactive virtual reality video game intended for Oculus devices in order for individuals to utilize the game to perform vestibular rehabilitation exercises. The activities in the video game are based on the Cawthorne-Cooksey exercises commonly used in vestibular rehabilitation. The exercises target eye movement, head movement, stretch movement, and bilateral coordination; repetitive motion is used to help train and treat the individual’s vestibular …

A Novel Approach Toward Concussion Testing, Jorge K. Mercado, Ari Schacter, Danielle Euzent

Student Theses

A concussion is a violent jarring or shaking of the head caused by whiplash or direct impact that results in a disturbance of brain function. Concussions can be mild and brief, as a person may be dazed momentarily or can be more serious, resulting in a loss of consciousness. Underreporting of concussions is prevalent because they are a symptom-based diagnosis, lacking a clinical test. In this study, we investigated the use of VNG testing as a clinical diagnosis of concussions. Looking at the VNG test battery, the previous research cohort found that saccades, gaze, and positional testing are the most …

Study Protocol: Investigating The Effects Of Uncarboxylated Osteocalcin And Anodal Trans-Spinal Direct Current Stimulation On Recovery Post-Spinal Cord Injury In Mouse Model, Wing To Ip, Parth Shah, Brandon Nam

Student Theses

Individuals with spinal cord injury often present with severe neuromuscular spasticity due to over-secretion of the neurotransmitter known as gamma-aminobutyric acid (GABA). Spasticity is made worse by the other sequelae of SCI, including muscle atrophy and loss of bone mineral density. This manuscript presents a study protocol that attempts to target such widespread physiological changes affecting multiple body systems. Our protocol establishes a potential treatment approach for SCI by combining recent advances in literature with a novel approach never seen before. We hypothesize

that the use of the already-promising anodal trans-spinal direct current stimulation (A- TSDCS) along with exogenous administration …

Neuroplasticity Of The Corticospinal System: Applications Of Neuromodulation-Based Therapies, Alzahraa M. Amer

Dissertations, Theses, and Capstone Projects

The motor cortex and corticospinal tract are necessary for producing skilled movements. I use intermittent theta burst stimulation (iTBS), a high-frequency stimulation protocol known to promote neural plasticity, as a tool to characterize short- and long-term plasticity of the CS system.

Although it is well known that activity-dependent motor cortex (MCX) plasticity produces long-term potentiation (LTP) of local cortical circuits, leading to enhanced motor evoked potentials (MEPs), the effects produced by the corticospinal (CS) projection on spinal cord neurons have not yet been thoroughly studied. In Chapter 2, I determined if the CS tract (CST) is capable of producing LTP …

Psychosocial Impacts And Employment Preparedness Of Participating In An Hiv Peer Program: Implications For Tailoring A Vocational Counseling Model For Plwh, Erin R. Mckinney-Prupis

Medical advancements in HIV care should have reduced barriers to employment for PLWH, yet in 2017 only 47.7% of PLWH reported being employed, as compared to 62.9% in the general population. Employment is a significant social determinant of health, it impacts a variety of factors related to health, including earned income, access to healthcare, and social connectedness. Quantitative and qualitative studies have identified several concerns PLWH have about entering the workforce; the most pressing being fear of losing benefits. Targeted work readiness programs for PLWH is an important approach to help PLWH overcome their unique barriers to work, such …

Controlled Observation: The Challenges Of Therapy For The Mentally Ill Incarcerated Population, Esther Tingué

Dissertations, Theses, and Capstone Projects

Popular perception and objective of incarceration is confinement, brutality and in some cases inhumane conditions. But what about the incarcerated population who suffer from the additional burden of mental illness? How does confinement affect mentally ill inmates? This capstone project asks: (1) how do individuals/organizations provide rehabilitative services in this evolved culture of crime and punishment? And (2) how is therapy provided in a restricted environment? I examine these questions from the perspective of the therapist, the person who (in a restricted environment) takes on the responsibility of treating and managing the effects of mental illness for this population.

Development Of An Aba Tool Kit For Audiologists To Increase Hearing Aid Wear Time In Individuals With Autism, Lindsay Brown

Dissertations, Theses, and Capstone Projects

When working with individuals with the dual-diagnosis of hearing loss and Autism Spectrum Disorder (ASD), audiologists are often faced with unique challenges and must adapt their approach in order to more effectively address the needs of these individuals. Currently, there is only a small body of research focused on the special considerations required for appropriately fitting and utilizing amplification for children with the dual-diagnosis of hearing loss and ASD. Subsequently, recommendations and strategies for clinicians to implement when faced with these common challenges, specifically of hearing aid compliance and appropriate hearing aid wear time, are lacking. It is important to …

The New World Of Pet Prosthetics, Anna Brooks

Capstones

When an abandoned dog was found in Brooklyn with his paw gnawed off, the animal shelter had two options: amputate the leg, or put the dog down. But neither seemed like a solution. So they decided to do something different, and fit the dog for a prosthetic leg. Prosthetics for people have been around for millennia, and now these devices are moving into the animal kingdom. This story explores the new world of animal prosthetics, and how these devices have changed the lives of animals like Mr. Stubbs — the first alligator with a prosthetic tail — and saved the …

Dios, Drogas, Dinero: ¿QuiéN Gana Con El Traslado De Adictos De Puerto Rico A Ee.Uu.?, Claudia E. Irizarry Aponte, Eliana Y. Perez

Capstones

For the last 25 years, evangelical leaders have been shipping off opioid addicts in Puerto Rico to cities in the mainland US, mainly New York City, Chicago and Philadelphia--under the promise they’ll receive state-of-the-art rehabilitation treatment, only to end up in unregulated transitional homes and flophouses where they don’t receive proper medical care or psychotherapy. In turn, many of these unregulated transitional homes, also run by evangelical leaders, may charge Medicaid kickbacks from their “patients.”

While this so-called “air bridge” from Puerto Rico to the U.S. goes back decades, it gained momentum from 2005 to 2014, when evangelical leaders joined …

The Effect Of A Voice Treatment On Facial Expression In Parkinson’S Disease: Clinical And Demographic Predictors, Amanda D. Bono

Dissertations, Theses, and Capstone Projects

Parkinson’s disease (PD) is a neurodegenerative disease associated with a wide range of motoric, cognitive, and behavioral symptoms. Impairments in facial mobility and emotional expressivity are common and can impair communication, in turn, affecting daily functioning and quality of life. Previous research suggests that the Lee Silverman Voice Treatment © (LSVT LOUD; Ramig et al., 2001, 2011) increases vocal loudness and facial expressivity in individuals with PD compared to PD and healthy controls. This study extends the literature by examining the effects of LSVT and an articulation-based control treatment (i.e., ARTIC) on multiple aspects of facial expressivity (i.e., emotional frequency …

Investigating The Effects Of Trans-Spinal Direct Current Stimulation On The Expression Of Nkcc1 In Mice, Pasindu Weliwaththage

Student Theses

Trans-spinal direct current stimulation (tsDCS) is a non-invasive powerful tool demonstrated to positively affect behavior and motor function. tsDCS is a neuromodulatory technique capable of altering spinal and cortical excitability and even regain motor function after complete motor paralysis (Cortes et at, 2017). tsDCS causes immediate and long-term effects in spinal excitability (Ahmed, 2011, 2013; Ahmed and Wieraszko, 2012; Cogiamanian et al., 2011, 2012). Studies have been conducted on both healthy and injured subjects. The ultimate goal is to ameliorate the devastating effects of Spinal Cord Injury. Though researchers have been successful in improving motor function, the molecular basis of …

Dancing, Mindfulness, And Our Emotions: Embracing The Mind, Body, And Sole, Alisha M. Collins

Dissertations, Theses, and Capstone Projects

This capstone project examines dance, as an intervention and mindfulness practice that assists with managing our emotions. There is a need for dance therapy in social institutions such as, healthcare facilities, schools, and community centers. Dance therapy has the potential to reduce negative emotions, create mindfulness, improve self-expression, and promote a healthy well-being. I am proposing that dance therapy is applied as a regular practice in social institutions to develop mindfulness and promote emotional stability.

In this study, I argue that dance therapy can contribute to our well-being long term. In addition to this written thesis, a visual component of …

The present study examined the potential of motor imagery training and investigated the role of motor imagery instructions (audio) to improve knee range of motion after a total knee replacement. The participants were randomly assigned to either an experimental motor imagery group (n=4) or a control group (n=6). Both groups performed specific exercises to improve their knee range of motion and strengthen their muscles. Participants in the Motor Imagery group performed a motor imagery training exercise for a knee flexion stretch on the stairs prior to performing the actual exercise. The motor imagery group demonstrated a significantly greater increase in …

Language-Mixing In Discourse In Bilingual Individuals With Non-Fluent Aphasia, Avanthi Paplikar

Dissertations, Theses, and Capstone Projects

Language-mixing (LM) as defined by Chengappa (2009, p. 417) is an “intra-sentential phenomenon referred to as the mixing of various linguistic units (morphemes, words, modifiers, phrases, etc.), primarily from two participating grammatical systems”. LM is influenced by grammatical, environmental, and social constraints (e.g., Milroy & Wei, 1995; Bhat & Chengappa, 2005). Researchers have suggested that LM in patients with aphasia is a communicative strategy used to achieve successful exchanges between speakers; the effectiveness of this mixing, however, had yet to be demonstrated quantitatively.

In the current study we investigated whether LM is present in bilingual speakers with aphasia, and if …

Reliability Of Clinical Evaluators Of Spasticity In Patients With Stroke, Tiffany Alvino, Shiney David, Chelsea Gendvil

Dissertations, Theses, and Capstone Projects

Spasticity is characterized by hyperexcitable stretch reflexes with amplitude increases in response to velocity dependent passive movement and resistance. Spasticity is the result of abnormal function of segmental and suprasegmental neuronal circuits. The objective of this study was to determine any positive correlation between three clinical evaluators of spasticity (i.e., the pendulum test, the patellar tendon tap test (PTT), and the Modified Ashworth scale) in their reliability to assess spasticity in people post-stroke. It was hypothesized that the use of force movement sensors along with surface electromyography increases the reliability of the standardized clinical tests. The results show that all …

Multi-Digit Coordination In Absence Of Cutaneous Sensory Feedback During Grasping Tasks, Christina Gioeli, Kerry Mcpartlan, Emily Reid, Matthew Turturro

Dissertations, Theses, and Capstone Projects

Motor learning and adaptation to object properties and task requirements requires integration of cutaneous sensory feedback with motor commands. Joint mechanics constantly change, with individual joints or muscles compensation so performance output is the same per task. Effects of mixed cutaneous sensory feedback on multi-digit coordination is not well understood. Investigators sought to determine the influence absent cutaneous sensory feedback has on motor learning and adaptation, and how the CNS coordinates multi-digit mechanical output to adapt to manual tasks, with partially intact digital sensory feedback. 19 participants were randomly assigned for three-digit anesthesia administration (TIM- thumb, index, middle; TRL- thumb, …

Paired Associative Transspinal And Transcortical Stimulation Produces Bidirectional Plasticity Of Human Cortical And Spinal Motor Pathways, Luke Dixon, Mohamed Ibrahim, Danielle Santora

Dissertations, Theses, and Capstone Projects

Anatomical, physiological, and functional connectivity exists between primary motor cortex (M1) and spinal cord neurons. Paired associative stimulation (PAS) produces enduring changes in M1 based on the Hebbian principle of associative plasticity. The present study aims to discover immediate neurophysiological changes on human corticomotor pathways by pairing noninvasive transspinal and transcortical stimulation via transcranial magnetic stimulation (TMS). We delivered paired transspinal and transcortical stimulation for 40-min at precise interstimulus intervals with TMS being delivered after (transspinal-transcortical PAS) or before (transcortical-transspinal PAS) transspinal stimulation. Transspinal-transcortical PAS markedly decreased intracortical inhibition, increased intracortical facilitation and M1 excitability with concomitant decreases of motor …

Physiopathology And Intervention In Osteoarthritis: A Systematic Review, Justin Gelesky, Dylann C. Germann, Amanda Percaccio, Rachelle Schick

Dissertations, Theses, and Capstone Projects

In the United States, osteoarthritis (OA) is the most common chronic illness in the adult population affecting an estimated 27 million individuals with a yearly health care cost of over $150 billion (CDC, 2014; Lawrence et al., 2008). The pathological osteoarthritic process results in the progressive degradation of articular cartilage due to chemical and biological imbalances within a joint (Weiland et al., 2005). These imbalances are not well understood and neither are the biomechanical joint changes that occur as a result. Due to these limitations, treating and monitoring this condition is a challenge to clinicians and the processes are currently …

Developmental Coordination Disorder: The Relationship Between Gait And Attention With Possible Implications For Early Identification And Intervention, Yocheved Bensinger-Brody

Dissertations, Theses, and Capstone Projects

The aim of this research was to evaluate how increased levels of challenge to attentional capacity would affect the motor planning and coordination in the gait of children at risk of Developmental Coordination Disorder (DCD) across developmental ages. The study incorporated a dual task paradigm requiring both motor and attention performance, with the primary hypothesis that children who are at risk of DCD across different ages (3- to 8 yrs.-of-age) would demonstrate an alteration in their motor strategies if they were simultaneously engaging in an attention task. A secondary hypothesis of this study was that there is an underlying deficit …

All subjects underwent baseline and post-training measurements using EMG recordings of the tibialis anterior, gastrocnemius, vastus lateralis and semimembranosus. Training was performing using repeated waist-pull …

Effect Of Absent Tactile Sensation On Multi-Digit Coordination Underlying Hand Control, Michael P. Alcorn, Bruce Faulkner, Matthew Macina, Brian Sherman

Dissertations, Theses, and Capstone Projects

We investigated the effect of anesthesia, causing absent tactile sensation feedback, on multi-digit coordination underlying hand control. The purpose of the study is to expand our understanding on the essential role of tactile sensation feedback in the sensorimotor integration process by examining the motor coordination patterns during multi-digit forces production tasks. We hypothesized that absent tactile sensation feedback would interrupt the force sharing pattern at local and non-local digits. Twelve participants were utilized for data collection and statistical analysis (25.6 ± 4.1 years old, 6 males and 6 females), right-handed (according to their preferred hand use for writing and eating) …

Investigating The Effects Of Combining Treadmill Training With Trans-Spinal Direct Current Stimulation On Motor Skill Recovery After Spinal Cord Injury, Jennifer Blake, Rebecca Bullen, Jeremy Pahl, Samantha Scicchigno

Dissertations, Theses, and Capstone Projects

This study assessed the effect of treadmill training with or without trans-spinal direct current stimulation on motor recovery following a T13/L1 spinal cord hemi section in CD-1 mice. Mice all received the same spinal cord injury, which resulted in left hind limb paralysis, and were assigned to one of three groups. Control animals received no treatment. Treadmill only mice were treated with 5 sessions of treadmill training. Treadmill + stimulation animals were treated with concurrent treadmill training and trans-spinal direct current stimulation. Progress was assessed by analyzing each subject’s steps on a horizontal ladder test, which the animals performed both …

The Effects Of Cooling During Gait On Gait Endurance In Persons With Multiple Sclerosis Using The Six Minute Walk Test, Meghan Higgins, Esther Sosowsky, Elisheva Zinberg

Dissertations, Theses, and Capstone Projects

Background: Persons with MS (pwMS) are limited in their mobility due to thermosensitivity. Exercising at a sufficient volume and intensity to increase mobility can result in increased core temperatures and resultant worsening of symptoms. The use of cooling garments to lower core temperature has been found to be a successful means of allowing pwMS to exercise for longer periods. Previous studies have relied on precooling for an extended period of time prior to activity, to achieve improved exercise performance. Cooling during the performance itself, or pericooling, may allow for similar performance gains to be realized without spending the time needed …
