A major challenge of tissue engineering is directing cells to establish the physiological structure and function of the tissue being replaced. Electrical stimulation has been used to induce synchronous contractions of cultured cardiac constructs. The hypothesis adopted for this study is that functional cardiac constructs can be engineered by "mimicking" the conditions present during cardiac development, and in particular, electrical stimulation using supra-threshold signals. For this Master's Thesis research, I have compared the material properties and charge-transfer characteristics at the electrode-electrolyte interface of various biocompatible materials, including carbon, stainless steel, titanium and titanium nitride, for use as electrodes in a biomimetic system for cardiac tissue engineering. I have also designed and implemented an electrical stimulator which is capable of modulating several important parameters of electrical stimulation, including stimulus amplitude and frequency.
(cont.) In addition, I have built an experimental setup incorporating this electrical stimulator and used it for experiments with C2C12 mouse myoblast cells and neonatal rat cardiomyocytes. Lastly, I have analyzed cell morphology as well as functional performance of engineered tissue by assessing excitation thresholds and maximum capture rates.

Almashaikhi, Talal. "Electrical brain stimulation and human insular connectivity." Thesis, Lyon 1, 2013. http://www.theses.fr/2013LYO10174/document.
Full textThe insular cortex is the fifth lobe of the brain and is in charge of the integration of many cognitive functions, underpinned by a rich cytoarchitectonic organization and a complex connectivity. Our work aims to evaluate the insular functional connectivity of the human brain using intracerebral electrical stimulation and recording of cortico-cortical evoked potentials (CCEPs) in patients investigated with stereoelectroencephalography (SEEG) for refractory partial epilepsy. We first developed an automated protocol to stimulate successively all intracerebral recorded bipoles (two contiguous leads of the same electrode) available in patients undergoing SEEG. Two sets of 20 monophasic stimulation of 1 ms duration and 1mA intensity were delivered at a frequency of 0.2 Hz at each bipole (105 on average, producing a total of about 11,000 recordings per patient). We then develop a reliable and objective statistical method to detect significant CCEPs as a complement to visual analysis, and validate this approach on a sample of 33017 recordings in three patients. The analysis was performed over four distinct post-stimulus epochs: 10-100 ms, 100-300 ms, 300-500 ms, 500-1000 ms. In the second part of our thesis, we applied these methods to the study of intrainsular connections on a sample of 10 patients with at least two intra-insular electrodes. The last part of our work used the same approach to investigate insular efferents in a sample of 11 patients. The study of CCEPs provides novel and important findings regarding the human brain functional connectivity, with unmatched spatial and temporal resolutions as compared to neuroimaging techniques. The complex management of large volume of data in each patient can be solved by automated statistical analysis procedures with satisfactory sensitivity and specificity. The pattern of connections within and outside the insula revealed by this approach provides a better understanding of the physiology of the Human insula as well as of the propagation of epileptic discharges involving this lobe

Full textLos tratamientos clínicos basados en la estimulación eléctrica de células excitables han sido eficaces y ampliamente utilizados para una variedad de enfermedades. Sin embargo, estos dispositivos a menudo están limitados por su volumen, la necesidad de electrodos con cableado externo y la incapacidad de actuar en células específicas. Los dispositivos implantables que pueden convertir la energía óptica o magnética en estímulos localizados eléctricos o térmicos para activar las células, son alternativas prometedoras. Esta tesis se centró en el desarrollo de nanomateriales opto-eléctricos y magneto-opto-eléctricos para la estimulación celular inalámbrica. Actualmente, los estimuladores opto-eléctricos generalmente requieren luz visible de baja penetración y altas intensidades, y los estimuladores magnetoeléctricos generalmente proporcionan una precisión espacial y temporal deficiente. En esta tesis, se han desarrollado dos tipos de nanomateriales para superar estos desafíos. El primer nanomaterial se basó en nanopilares Si/Au para lograr la estimulación opto-eléctrica en la primera y segunda ventanas biológicas del infrarrojo cercano con intensidades de luz ultrabajas. Las simulaciones teóricas predijeron que los nanopilares de Si coronados por nanodiscos Au exhiben una mejora de 6 veces en la absorción de luz en comparación con la oblea de Si simple. Tal mejora se debe a la excitación de nuevas resonancias híbridas de metal/dieléctrico. A continuación, se presentó un exhaustivo análisis experimental opto-eléctrico-químico de los nanopilares de Si/Au. Los nanopilares cortos de Si/Au dieron el mayor rendimiento opto-eléctrico, logrando un fotovoltaje de 80 mV a una intensidad de luz ultrabaja de 0,44 µW/mm2, que fue 11 veces mayor que la oblea p-n Si simple. La fotocorriente también mostró una mejora sustancial de 2.5 veces, mostrando una combinación de corrientes capacitivas y faradaicas inducidas por la luz que pueden ajustarse con la densidad de los nanopilares Si/Au. Además, los nanopilares cortos de Si/Au mostraron una ventana de frecuencia de 50-200 Hz para maximizar la fotovoltaje y la fotocorriente. Finalmente, la biocompatibilidad de las nanoestructuras Si/Au fue validada por ensayos de viabilidad celular. El segundo nanomaterial estaba compuesto por matrices de nanocúpulas huecas de FeGa/ZnO integradas en una película elastomérica flexible y biocompatible. La estimulación magnetoeléctrica propuesta se basa en la magnetostricción del FeGa y la piezoelectricidad del ZnO. La estimulación optoeléctrica se basa en la absorción de luz infrarroja por el FeGa y la respuesta piroeléctrica del ZnO. Los resultados del comportamiento magnético revelaron que las matrices hexagonales empaquetadas con un diámetro de 400 nm proporcionaron el campo magnético de saturación más bajo y una remanencia mínima. El análisis fototérmico mostró un intenso calentamiento óptico para longitudes de onda de luz de 808 nm y 1064 nm. La biocompatibilidad se demostró evaluando la viabilidad de las células Saos-2 óseas. En conclusión, los actuadores celulares nanoestructurados de Si/Au y FeGa/ZnO constituyen nuevas plataformas para la modulación electrofisiológica inalámbrica mediante luz infrarroja y campo magnético. Mirando hacia el futuro, son prometedores como nanoactuadores inyectables e implantables in vivo debido a las posibles optimizaciones, como la fabricación en sustratos flexibles y la funcionalización de su superficie para su unión a tipos celulares específicos, que podrían ser ampliamente aplicables tanto a los estudios biológicos fundamentales como a terapias clínicas.

The research conducted for this thesis investigated the theoretical placement of electrodes for a proposed implantable vestibular prosthesis to aid patients suffering from balance related disorders. The most likely sites of stimulation for the first-generation of such a device are the peripheral nerves responsible for transmitting rotational information to the brain. Although stimulation of such nerves has been performed in human and animal patients, little is known about the mechanisms responsible for the eliciting nerve responses. Models of the inferior and superior divisions of peripheral vestibular nerve were created to characterize the stimulus threshold behavior across the parameters of fiber diameter and location within the nerve. Current-distance relations were derived for nerve fibers excited by six commonly used electrode configurations. The threshold relations were used as a guide to determine the electrode configuration and location best-suited to stimulate the inferior vestibular nerve and selectively stimulate the branches of the superior vestibular nerve. The criteria used determine optimal placement included minimum current thresholds, configuration simplicity, and distance to the electrode. For the inferior nerve case, a cathodal stimulus located at a distance of 100 pm or 200 ym from the nerve and driven with a stimulus current of 56 pA or 76 pIA was recommended. For the superior vestibular nerve case we were interested in selectively stimulating each branch, imposing a further criteria to maximize the threshold ratio between stimulation of the respective branches. A transverse dipole electrode configurations was suggested that allowed selective stimulation of either branch. The configuration included a cathode located 300m from Branch 1 and an anode centrally located between both branches.
(cont.) When driven with a cathodal stimulus of strength 51 pA, only Branch I was excited, while driving both electrodes with a magnitude of 106 jIA excited only Branch II. The proximity to the facial nerve was considered in the choices

Full textTen (10) normal subjects received electrical stimuli of maximal tolerable intensity to the sole of their foot. Our results indicated that TENS could suppress the FR in 50% to 70% of subjects. However, longer durations (30 and 60 min) of TENS have a small, but discernible difference in the number of subjects that show inhibition of FR area and significant maximal FR suppression when compared to 10 min of TENS. Moreover, the 60 min of TENS generated significant depression of VAS scores in more subjects than 10 and 30 min of TENS and ensured that any increase in pain perception would not reach significance when compared to the shorter (10 and 30 min) durations of TENS.
Our results suggested that longer durations of TENS could be applied to produce antinociceptive and analgesic effects. (Abstract shortened by UMI.)

Full textBACKGROUND: Hamstring injuries remain a growing concern within a large variety of sports from the elite athlete to the weekend warrior. A copious amount of research has been performed in an attempt to reduce these injuries. The aim of this study was to understand the changes in lengthened state eccentric strength of the hamstrings following four separate protocols. METHODS: A quantitative research approach, using a true experimental design, was adopted for this study. A convenience sample of non-sedentary, 35 male participants, between the ages of 18 and 35 within the City of Cape Town was used. Participants were randomly allocated to one of four groups namely; Control group (C), resistance training alone (RT), neuromuscular electrical stimulation alone (NMES), or NMES superimposed with RT (NMES&RT). Participant’s eccentric hamstring strength was tested in a lengthened state, on the Biodex system 4 Pro™ for the pre- and post-test. The intervention spanned over four weeks. SPSS version 25 was used for data analysis. RESULTS: All groups demonstrated a mean increase in relative peak torque. However, a repeated-measures analysis of variance (ANOVA) showed no interaction effect (p = 0.411) between the four groups. Further analysis using Magnitude-based inferences (MBI), to identify the magnitude of changes, showed a small positive effect for both the NMES and NMES&RT group when compared to the C and RT groups. CONCLUSION: Although there are no statistically significant differences between the four groups employed in this study (C, RT, NMES, NMES&RT), NMES and NMES&RT did show small positive effects compared to C and RT with a very low likelihood of negative effects. Thus, using NMES either alone or superimposed with resistance training will be beneficial for trained athletes but it is not a necessity and the use of specific resistance training may be just as effective.

Full textENGLISH ABSTRACT: Swallowing disorders are prevalent in many elderly individuals and are common amongst individuals suffering from neurological diseases. These individuals are affected from slight swallowing difficulty to total swallowing inability. In severe cases this may cause aspiration pneumonia, dehydration, malnutrition and ultimately death. Swallowing disorders can be diagnosed and treated to increase quality of life. New treatment strategies to understand the pathophysiology and impaired swallowing response are needed. Neuromuscular electrical stimulation is used as rehabilitation method in various disciplines. This method of rehabilitation of physiological dysfunction is used in treating swallowing disorders and has become a focus for current research. To understand the effect of electrical stimulation to the swallowing centre it is proposed to study its mechanism on normal swallowing musculature. The outcome of the effect that electrical stimulation has on healthy individuals may possibly be used to extrapolate to clinical settings and its benefit for modern dysphagia rehabilitation. The purpose of this study was to report on the hyo-laryngeal movement pattern of young healthy, male and female, individuals and to measure the effect of a single neuromuscular electrical stimulation session on the hyo-laryngeal complex of 22 young healthy individuals. Lastly, the aim was to determine the detraining or lasting effect on the hyo-laryngeal swallowing complex of a single neuromuscular electrical stimulation session. The study reported on baseline hyo-laryngeal complex movement patterns by measuring the anterior movement and elevation of the hyo-laryngeal complex through the use of videofluoroscopy swallow study. Analysis of these measurements where done to report on the effect of electrical stimulation on the hyo-laryngeal complex movement pattern pre- and post- electrical stimulation. Significant changes were revealed with elevation of the hyo-laryngeal complex, however no significant effects could be found with anterior movement of the hyo-laryngeal complex pre- and post- electrical stimulation. It was found that elevation of the hyo-laryngeal complex lowered after a single electrical stimulation session. The hyo-laryngeal complex movement pattern remained similar between genders. Lastly it was found that a single electrical stimulation session showed significant reversibility towards baseline levels. This might be related to muscle fatigue and one would need to take into account muscle recovery for future research.
AFRIKAANSE OPSOMMING: Sluk versteurings is algemeen onder bejaardes asook individue wat ly aan neurologiese siektes. Hierdie individue word geaffekteer deur matige sluk probleme tot totale sluk onvermoë. In ernstige gevalle kan dit aanleiding gee tot aspirasie longontsteking, dehidrasie, wanvoeding en selfs dood. Sluk versteurings kan gediagnoseer en behandel word om die kwaliteit van lewe te verbeter. Dit is daarom noodsaaklik om die patofisiologiese en verswakte sluk reaksie te verstaan om sodoende nuwe behandeling strategieë te ontwikkel. Neuromuskulêre elektriese stimulasie word gebruik as rehabilitasie tegniek in verskeie dissiplines. Hierdie metode van behandeling van fisiologiese disfunksie word ook gebruik in die behandeling van sluk afwykings en geniet tans baie navorsings aandag. Om die effek van elektriese stimulasie op die sluk sentrum te verstaan word dit dus voorgestel dat die meganisme op die normale sluk spierstelsel bestudeer word. Hierdie bevindinge kan dus moontlik toegepas word op persone met sluk afwykings en sodoende meer effektiewe rehabilitasie tegnieke bevorder. Die doel van hierdie studie was om die effek op die hyo-laringeale bewegings patroon van jong, gesonde, manlike en vroulike individue te bestudeer, asook om verslag te doen oor die uitwerking van 'n enkele neuromuskulêre elektriese stimulasie sessie op die hyo-laringeale kompleks van 22 jong, gesonde individue. Laastens was die doel van hierdie studie ook om die blywende effek van 'n enkele sessie neuromuskulêre elektriese stimulasie op die sluk sentrum te bepaal. Die studie het basislyn hyo-laringeale kompleks bewegings patrone gerapporteer deur die voorwaartse asook opwaartse beweging van die hyo-laringeale kompleks te meet deur gebruik te maak van videofluoroskopie sluk studies. Ontleding van hierdie metings is gedoen om die uitwerking van elektriese stimulasie op die hyo-laringeale kompleks bewegings patroon voor en na elektriese stimulasie te bepaal. Beduidende veranderinge is in die opwaartse beweging van die hyo-laringeale kompleks gevind, alhoewel geen veranderinge gevind is in die voorwaartse beweging van die hyo-laringeale kompleks voor en na elektriese stimulasie nie. Daar is vasgestel dat die opwaartse beweging van die hyo-laringeale kompleks verlaag het na 'n enkele elektriese stimulasie sessie. Verder het die hyo-laringeale kompleks bewegings patroon geen beduidende verskille tussen geslagte getoon nie. Laastens is bevind dat 'n enkele elektriese stimulasie sessie beduidende omkeerbaarheid terug na basislyn vlakke van beweging toon. Dit kan verband hou met die uitputting van die hyo-laringeale spiere as gevolg van die elektriese stimulasie en toekomstige navorsing sal dus uitputting, asook die tempo van herstel in ag moet neem.

The goal of the Retinal Implant Project is to restore useful vision to patients with degenerative diseases of the retina. Electrical stimulation of the retina via a microelectrode array is achieved using a battery powered stimulation system. This thesis describes the design of this system, including features that ensure the subject's safety from electrical shock. The stimulation system delivers charge balanced current pulses to the 100 electrodes in the array. The system has been tested in the laboratory setting as well as in rabbit experiments and one human retinal stimulation trial. It functions as specified, and is very robust.

Full textIntroduzione: Le fibre del muscolo scheletrico possiedono una notevole capacità di modificare le loro proprietà molecolari, funzionali e metaboliche in risposta a stimoli di crescita e ambientali. Esperimenti di cross-innervazione e stimolazione elettrica hanno dimostrato il ruolo fondamentale dell’attività neuromuscolare nel determinare il tipo di fibra. La stimolazione cronica a bassa frequenza (CLFS) è in grado di indurre il processo di trasformazione di una fibra veloce verso un fenotipo lento. Fino ad ora, questi processi sono stati studiati dopo lunghi periodi di stimolazione. In questo lavoro, mi sono proposta di identificare i cambiamenti trascrizionali precoci di questo processo. Metodi: Il muscolo veloce EDL di topo è stato sottoposto a CLFS per 6 e 12 ore. Inizialmente ho utilizzato il muscolo intero per produrre i profili di espressione Successivamente, per ovviare al problema dell’eterogenea composizione del muscolo, ho utilizzato l’approccio microgenomico, producendo profili di espressione a livello di una singola fibra, isolata utilizzando il protocollo sviluppato nel mio laboratorio. Tutti i profili sono stati ottenuti mediante l’utilizzo di piattaforme Agilent (SurePrint G3 Mouse GE 8x60K). Risultati e discussione: I profili di espressione con il muscolo intero hanno identificato circa 200 geni differenzialmente espressi (DE). Lo sviluppo dei vasi sanguigni e la regolazione della trascrizione sono risultate le categorie funzionali più arricchite. Le analisi genomiche a livello di singola fibra hanno identificato più di mille geni DE dopo 12 ore di stimolazione. La categoria funzionale riguardante lo sviluppo dei vasi sanguigni risulta arricchita anche con questo approccio, suggerendo un’interazione tra le fibre muscolari e gli altri tipi cellulari al fine di stimolare il processo di angiogenesi. La maggiorparte dei geni strutturali risulta essere ugualmente espressa, suggerendo che i cambiamenti nel tipo di fibra richiedono un tempo prolungato. Al contrario, i geni coinvolti nella trascrizione, nel rimodellamento della cromatina e alcuni geni miofibrillari che agiscono come molecule di segnale, si attivano rapidamente in risposta a CLFS.

Full textPatients with epilepsy are well known to be at increased risk of sudden unexpected death. The risk of Sudden Unexpected Death in Epilepsy Patients (SUDEP) ranges from 0.35 to 2.3 per 1000 people per year in community-based populations, to 6.3 to 9.3 in epilepsy surgery candidates. SUDEP’s precise agonal mechanisms are unknown, although recent evidence from the Mortality in Epilepsy Monitoring Units Study (MORTEMUS) points to combined respiratory and cardiovascular collapse driving the fatal event. Adverse autonomic nervous system signs are prominent during seizures. Cardiac arrhythmias (bradycardia, asystole, tachyarrhythmias) in approximately 72% of epilepsy patients, post-ictal hypotension, impaired baroreflex sensitivity (potentially compromising cerebral blood flow), enhanced sympathetic outflow, expressed as increased sweating and decreased inter-ictal nocturnal heart rate variability (HRV) are common. Severe alteration of breathing is typically seen in generalized tonic clonic seizures (GTCS). Electroencephalogram (EEG) characteristics, including post-ictal generalized EEG suppression (PGES), are suggestive of high SUDEP-risk, strongly correlate with increased sweating and decreased HRV, and may be accompanied by profound hypotension. Neural mechanisms underlying these patterns need to be defined. Epilepsy is a prototypic cortical disorder, where most of the symptoms are produced by the activation or inhibition of specific regions in the cortex. Epileptiform discharges involving a specific area in the brain may induce symptoms related with that area’s functionality. In a similar manner, electrical brain stimulation can be used to map brain functions. Although several studies using brain electrical stimulation have suggested the possible role of cortical structures in respiration and autonomic control, reports from some investigators have indicated mixed findings, such that there is no consensus on the precise areas of cortex concerned. We aimed to identify cortical sites with roles in respiratory and/or autonomic control and to correlate seizure induced activation or inhibition of these structures to particular peri-ictal autonomic and breathing patterns recognized as potential indices of risk for death. This study describes the role of several limbic/paralimbic structures in respiration and human blood pressure control, and pathomechanisms of breathing and autonomic responses during epileptic seizures, providing insights into mechanisms of failure in SUDEP.

Full textComparing the experimental side to the normal contralateral muscle, ES versus no ES resulted in a preservation of muscle weight--73% vs 39% (p $<$.01); twitch tension--21% vs 7% (p $<$.001); nerve stimulated tetanic tension--23% vs 7% (p $<$.05); direct muscle stimulated tetanic tension--43% vs 11% (p $<$.01); Type I fiber area--69% vs 46% (p $<$.05); and Type II fiber area of 63% vs 34% (p $<$.05). There was no statistically significant difference between the two groups in the fiber type proportions.
The results of this project support the hypothesis that continuous, implantable ES delivered over an extended period of time has a positive functional and morphological impact on denervated muscle. (Abstract shortened by UMI.)
