INFLUêNCIA DA EQUOTERAPIA NO CONTROLE CERVICAL E DE TRONCO EM UMA CRIAN A COM PARALISIA CEREBRAL
Alessanda Gregório,Eddy Krueger
Revista Uniandrade , 2013,
Abstract: A equoterapia é um método fisioterápico que se baseia na utiliza o do trote do cavalo como meio de tratamento em pacientes com sequelas sensoriais e motoras decorrentes de distúrbios neurológicos. Por tratar-se de um estudo de caso, o objetivo deste trabalho é avaliar a influência da equoterapia no controle cervical e de tronco em uma crian a com paralisia cerebral (PC). A crian a participante possui dois anos de idade e diagnóstico médico de tetraparesia espastica. Foram realizadas duas avalia es utilizando a escala de Gross Motor Function Measure (GMFM) antes e após todo o período das sess es de equoterapia. Esse método de avalia o consiste em 88 itens divididos em cinco dimens es: A, deitar e rolar; B, sentar; C, engatinhar e ajoelhar; D, em pé; e E, correndo e pulando. Utilizaram-se as dimens es A e B da escala GMFM no presente estudo. A equoterapia foi desenvolvida durante dez sess es de trinta minutos, utilizando montarias distintas. Observou-se que o controle cervical e o controle de tronco estavam presentes ao término do tratamento, que é comprovado com o aumento de 19,5% e 7,7% para as dimens es A e B da escala GMFM, respectivamente. A equoterapia apresentou grande eficiência no ganho do controle cervical e de tronco da crian a com PC.

Open Journal of Biophysics (OJBIPHY) , 2013, DOI: 10.4236/ojbiphy.2013.33021
Abstract:

Mechanomyography (MMG) acquires the oscillatory waves of contracting muscles. Electromyography (EMG) is a tool for monitoring muscle overall electrical activity. During muscle contractions, both techniques can investigate the changes that occur in the muscle properties. EMG and MMG parameters have been used for detecting muscle fatigue with diverse test protocols, sensors and filtering. Depending on the analysis window length (WLA), monitoring physiological events could be compromised due to imprecision in the determination of parameters. Therefore, this study investigated the influence of WLA variation on different MMG and EMG parameters during submaximal isometric contractions monitoring MMG and EMG parameters. Ten male volunteers performed isometric contractions of elbow joint. Triaxial accelerometer-based MMG sensor and EMG electrodes were positioned on the biceps brachii muscle belly. Torque was monitored with a load cell. Volunteers remained seated with hip and elbow joint at angles of 110° and 90°, respectively. The protocol consisted in maintaining torque at 70% of maximum voluntary contraction as long as they could. Parameter data of EMG and the modulus of MMG were determined for four segments of the signal. Statistical analysis consisted of analyses of variance and Fishers least square differences post-hoc test. Also, Pearson’s correlation was calculated to determine whether parameters that monitor similar physiological events would have strong correlation. The modulus of MMG mean power frequency (MPF) and the number of crossings in the baseline could detect changes between fresh and fatigued muscle with 1.0 s WLA. MPF and the skewness of the spectrum (μ3), parameters related to the compression of the spectrum, behaved differently when monitored with a triaxial MMG sensor. The EMG results show that for the 1.0 s and 2.0 s WLAs have normalized RMS difference with fatigued muscle and that there was strong correlation between parameters of different domains.

Abstract: within the last 50 years the light and specially the laser has fomented great advances in several areas of science and technology. during the past decade the use of optical stimuli in the biomedical research field have been of great interest for both academy and industry. two research branches that can be highlighted due to its growth are: direct optical stimulation and optogenetic. the first one uses different parameters of light to optimize the desired effect on the tissue interaction. the other branch works with genetic engineering technics to make cells sensitive to light. the neural stimulation by infrared (direct optical stimulation) does not require direct contact with the tissue and has higher spatial selectivity when compared to electrical stimulation, but it has restricted ability to activate (depolarize) neurons. the optogenetic, however, can be used to manipulate the neural tissue depolarizing or hyperpolarizing encoded neurons, as well as monitor activations by encoding fluorescent proteins sensitive to voltage. the stimulation by infrared optical or optogenetic, has been applied only to animal models although there is a great possibility for human applications. in the future, it may even replace existing techniques such as electrical brain stimulation to treat specific neurological diseases.

Abstract: introduction: the action potential (ap) arises due to a disturbance of the resting state of the cell membrane with consequent flow of ions across the membrane and ion concentration changes in intra and extra cellular space. objectives: this article aims to summarize the scientific knowledge accumulated to date on the action potential and neural adaptation in the process of applying a constant stimulus. materials and methods: this is a literature review on the bases springer, sciencedirect, pubmed, ieee xplore, google scholar, capes periodicals portal as well as books on the topic. the selected preferred language was english with the keywords: action potential; adaptation, accommodation; rheobase; chronaxy; nerve impulse. we conducted a search of articles with a wide time window from 1931 to 2010 and books from 1791 to 2007. results: in the selected studies was extracted information about the following topics: action potential and its stages; nerve conduction; rheobase; chronaxie, accommodation, and adaptation. conclusion: a stimulus that creates ap, if applied consistently, can reduce the frequency of depolarization as a function of time and, consequently, to adapt the cell. the time it takes the cell in the absence of stimuli, to recover its original frequency, is defined as a disadaptation.
A Novelty-Induced Change in Episodic (NICE) Context Account of Primacy Effects in Free Recall  [PDF]
Eddy J. Davelaar
Psychology (PSYCH) , 2013, DOI: 10.4236/psych.2013.49099
Abstract:

Formal cognitive models of episodic memory assume that during encoding list items become associated with a changing context representation. However, this representation is recency-biased and thus can not account for primacy effects under conditions that prevent rehearsal. In this paper, it is hypothesized that one source underlying primacy effects is the detection of novelty. In three experiments, it is shown how novelty at the perceptual and semantic level can explain the full serial position function of first recall probabilities, including primacy effects. It is proposed that an item becomes distinctive due to increase in the change within a distributed episodic context representation, induced by novelty detection. The theory makes three assumptions. First, items become associated with a distributed context representation. Second, the context representation changes with item presentation. Third, the rate of contextual change is related to the perceptual and conceptual difference computed between the presented item and the previous item (or items in the buffer). This theory captures primacy effects in first recall probabilities without recourse to a rehearsal process and provides a mechanistic account of distinctiveness.

Vreugde en verdriet in die huis van Jakob

Abstract: Happiness and lament in the house of Jacob: The birth narrative in Genesis 29:31-30:24 is a coherent mini drama in its own right, although it is embedded in the patriarchal narratives and as such furnishes important background to the unfolding drama in Jacob\'s house. In this narrative, the reader is invited right into the intricate family relations of a dysfunctional polygamous marriage, where two rivals communicate with each other and their mutual husband by means of the names given at birth to their children and the children of their slave girls. This article focuses on the quest for happiness, which is evident in the births and name-giving in the house of Jacob. Although true happiness remains elusive, at the end both women receive their dues. God keeps a balance between the two contenders, but the birth of Rachel's son calls for a resolution still to come. The text is thus left open ended. HTS Theological Studies Vol. 64 (2) 2008: pp. 935-957
