Application of muscle/nerve stimulation in health and disease by Gerta Vrbová( )

20 editions published between 2008 and 2011 in English and held by 577 WorldCat member libraries worldwide

The book provides essential information for Colleges and Training Centres who offer physiotherapy, beauty therapy and sports science courses as it explains both the scientific principles and the practical applications of electrotherapy. It also offers valuable information for all those interested in keeping fit with electrical stimulation, in an increasingly sedentary society where active exercise is difficult to maintain at adequate levels or when an injury or illness prevents active exercise. Electrical stimulation is an invaluable method of achieving better recovery of function after disabi
Nerve-muscle interaction by Gerta Vrbová( Book )

23 editions published between 1978 and 2012 in 3 languages and held by 491 WorldCat member libraries worldwide

In the second century, Galen recognized that nerve and muscle were functionally inseparable since contraction of muscle occurred only if the nerves supplying that muscle were intact. He therefore concluded that the shortening of a muscle was controlled by the central nervous sytem while the extension of a muscle could occur in the absence of innervation. Nerves, he thought, were the means of transport for animal spirits to the muscles; the way in which animal spirits may bring about contraction dominated the study of muscle physiology from that time until the historical discovery of Galvani that muscle could be stimulated electrically and that nerve and muscle were themselves a source of electrical energy. It is now well known that nerves conduct electrically and that transmission from nerve to striated muscle is mediated by the chemical which is liberated from nerve terminals onto the muscle membrane. In vertebrates this chemical is acetylcholine (ACh). Thus the concept of spirits that are released from nerves and control muscle contraction directly, is no longer tenable. Nevertheless the concept of 'substances' transported down nerv~s which directly control many aspects of muscle has not been abandoned, and has in fact been frequently reinvoked to account for the long-term regula tion of many characteristics of muscle (see review by Gutmann, 1976) and for the maintenance of its structural integrity

Electrical stimulation and neuromuscular disorders by W. A Nix( Book )

6 editions published in 1986 in English and Undetermined and held by 151 WorldCat member libraries worldwide

In many cases of neuromuscular disorders the physician is faced with a complete lack of therapeutic approaches. This helplessness places the doctor in a position of conflict between his desire to help and his awareness that there is no treatment. In this situation it is tempting to indiscriminately use any procedure that avoids an admission of medical helplessness while satisfying the patient's demand for treatment. Electrical interventions are often used to avoid this situation. Due to the random use of therapeutic approaches it is not known what really happens. Presumptions and biased empirical observations have led to the exten sive use of different forms of electrical stimulation regimes in neuromuscular diseases. Due to this unsatisfactory situation it is necessary to know more about appropriate methods that are being used in particular disorders. The search for a better understanding of nerve-muscle interaction has shown that certain activity patterns can influence muscle. These experi mental results provide a rational basis for a possible therapeutic use of electrical stimulation of nerve and muscle. Previously most research has been conducted in normal tissue, and little is known regarding the re sponses of diseased muscle. In an interdisciplinary approach to this, it is our intention to present the current knowledge about basic principles of electrical stimulation in normal muscle. Before electrical stimulation can be accepted as a therapeutic tool, we felt it necessary to summarize the effects of activity in normal and diseased muscle and nerve

Transplantation of neural tissue into the spinal cord by Antal Nógrádi( Book )

4 editions published in 1994 in English and held by 40 WorldCat member libraries worldwide

The book gives an account of results obtained from experiments where grafts of neuronal, glial and other tissues as well as artificial materials were placed into the spinal cord. It attempts to evaluate the contributions made by these studies to our understanding of basic neurobiologies questions. These include factors that regulate neuronal growth during development as well as regenera tion following injury to the nervous system. The model of neural transplanta tion is also useful for the study of cell-to-cell interactions, and this applies to interactions between glial cells and neurones, between various populations of neuronal cells and finally between axons and skeletal muscle fibres. The mecha nisms involved in the establishment of specific synaptic connections between neurones can also be investigated in this experimental paradigm. Important in formation regarding this issue was also obtained on systems other than the spinal cord, i. e. the cerebellum, hippocampus and striatum. Although such in formation of precise connections between the host and the grafted embryonic tissue is still lacking in the spinal cord, there is much information on the re sponse of the host nervous system to the grafted embryonic tissue, and that of the graft to its new host environment. It appears that embryonic grafts are able to induce repair processes follow ing injury to the nervous system

Restorative neurology of spinal cord injury by Milan R Dimitrijevic( Book )

1 edition published in 2012 in English and held by 3 WorldCat member libraries worldwide

Following injury or disease, neural circuitry can be altered to varying degrees leading to highly individualized characteristics that may or may not resemble original function. In addition, lost or partially damaged circuits and the effects of biological recovery processes coupled with learned compensatory strategies create a new neuroanatomy with capabilities that are often not functional or may interfere with daily life. To date, the majority of approaches used to treat neurological dysfunction have focused on the replacement of lost or damaged function, usually through the suppression of surviving neural activity and the application of mechanical assistive devices. Focusing on the spinal cord and its role in motor control, the book details the clinical and neurophysiological assessment process and methods developed throughout the past half century by basic and clinical scientists. Then, through the use of specialized clinical and neurophysiological testing methods, conduction and processing performed within the surviving neural circuitry is examined and characterized in detail. Based on the results of such assessment, treatment strategies, also described in this book, are applied to augment, rather than replace, the performance of surviving neural circuitry and improve the functional capacity of people who have experienced injury to their spinal cords
Biology of some neuromuscular disorders = Biologija nekaterih živčnomišičnih bolezni by Gerta Vrbová( )

1 edition published in 2004 in English and held by 2 WorldCat member libraries worldwide

Živčnomišične bolezni bomo bolje razumeli in morebiti zdravili le na podlagi analize bioloških procesov, ki povzročajo prizadetost. V prispevku predstavljamo poskuse takšne analize na dveh primerih iz skupine dednih živčnomišičnih bolezni: 1) Duchennove mišične distrofije (DMD) in spinalne mišične atrofije (SMA). DMD je na x-kromosom vezana dedna bolezen mišic, ki povzroča napredujočo mišično šibkost. Patološko spremenjeni gen, ki povzroča DMD, določa na mišično celično membrano vezani protein distrofin. Poskusi nadomestiti patološko spremeujeni gen/protein v mišicah so bili že napravljeniz uporabo prenosa mioblastov in zarodnih celic ter neposrednega vnosa dednine/gena v mišice dečkov z DMD. Drugi smiselni terapevtski pristopi bi lahko temeljili na razumevanju adaptacijskih zmožnosti skeletne mišice na različne funkcijske zahteve in dokazane zmožnosti ekspresije novih nizov genovv mišičnih celicah v odgovor na takšne zahteve. Nateg ali prekomerna obremenitev normalnih mišičnih celic vodita v spremenjeno ekspresijo genov v mišicah, verjetno pa lahko terapevtske uspehe razteznih vaj oziroma uporabe ortoz v te namene pri dečkih z DMD pripišemo istemu mehanizmu mišične adaptacije. Tudi električna stimulacija je močan stimulus indukcije ekspresijenovih genov. Njeni ugodni učinki na napredovanje mišične distrofije so že dokazani tako na živalskem modelu (miš) kot na človeku. Spinalna mišičnaatrofija je klinično heterogena skupina dednih živčnomišičnih bolezni, za katero je značilna izguba spodnjih motoričnih nevronov z napredujočo mišično šibkostjo in mišičnimi atrofijami. SMA se deli v tri oblike glede na stopnjo izraženosti bolezni in na starost ob pojavu bolezni. Vse tri oblike SMA so vezane na peti kromosom (Sq11.2-13.2), to je na regijo, ki določa gen SMN ("survival motoneuron gene"). (Izvleček skrajšan pri 2000 znakih)
The effects of separation from the target fast muscle on the survival of developing motoneurones : [abstracts] by Sanusi J( )

1 edition published in 1997 in English and held by 1 WorldCat member library worldwide

Previous reports show that following nerve crush injury after postnatal day 5, the number motoneurones to both slow, soleus and fast tibialis anterior (TA)/extensor digitorum longus (EDL) muscles were not affected. However, when the period of separation from the target muscle was increased, the number of motoneurones to the soleus muscle was reduced to 59% of the control side (Lowrie, 1990). In this study, we tested whether extending the period of separation from the target muscles will have any effects on the survival of motoneurones to the fast, TA/EDL muscles. The sciatic nerve was crushed in one hindlimb of 5 day old Wistar rats under halothane anaesthesia and sterile conditions
Effect of fatiguing maximal voluntary contraction on excitatory and inhibitory responses elicited by transcranial magnetic motor cortex stimulation( )

1 edition published in 1996 in English and held by 1 WorldCat member library worldwide

Vertex transcranial magnetic stimulation (TMS) elicited tibialis anterior motor evoked potentials (MEPs) and silent periods (SPs) that were recorded during and following isometric maximal volitional contraction (MVC). During MVC in 6 healthy subjects, MEP amplitudes in the exercised muscle showed an increasing trend from an initial value of 4539 +/- 809 muV (mean +/- SE) to 550 +/- 908 muV (P <0.13) while force and EMG decreased (P <0.01). Also, SP duration increased from 165 +/- 37 ms to 231 +/- 32 ms (P <0.01). Thus, during a fatiguing MVC both excitatory and inhibitory TMS-induced responses increased. TMS delivered during repeated brief 10% MVC contractions before andafter a fatiguing MVC in 5 subjects, showed no change in MEP amplitude but SP duration was prolonged after MVC. This SP prolongation was focal to the exercised muscle. Silent periods recorded after pyramidal tract stimulation were unchanged following the MVC. These results suggest that MEP and SP might have common sources of facilitation during an MVC and that inhibitory mechanisms remain focally augmented following a fatiguing MVC
