Similarly buy 1000 mg carafate overnight delivery gastritis diet plans, stimulation of pharyngeal areas results in increased excitability of the pharyngeal motor cortical representation buy 1000 mg carafate free shipping gastritis diet for children. These changes evoked by somatosensory stimulation on motor cortical function raised the hypothesis of the possible use of this intervention in patients with weakness secondary to stroke. This inter- vention resulted in a mild improvement in pinch force relative to a control intervention. Interestingly, the magnitude of improvement correlated with the intensity of the electrical stimulation. Two of these patients spontaneously reported that they could hold objects, write and play cards more easily for approximately 24 h. EFFECTS OF CORTICAL STIMULATION ON MOTOR CORTICAL FUNCTION AND CORTICAL PLASTICITY In animal models, cortical stimulation of a body part representation in the motor cortex results in increased motor maps targeting that particular body part. In healthy human volunteers, application of cortical stimulation techniques also modulates cortical excitabil- ity. These features make this technique potentially an appealing tool to purposefully modulate cortical function. Three main parameters of cortical stimulation influence the outcome: frequency, intensity, and duration of stimulation. Ziemann et al demonstrated that low-frequency TMS applied to the motor cortex can enhance deafferentation-induced plasticity in intact humans,166 expressed as changes in intracortical inhibition and intracortical facilitation. They have been identified with stimulation of the plastic motor cortical representation (upper arm in this study), but not with stimulation of nearby body part representations (hand or face). The importance of these findings is that they demonstrated, as a proof of principle, that TMS can modulate human cortical plasticity. These findings led to the investigation of the effects of cortical stimulation on use- dependent plasticity (UDP), fundamentally relevant in neurorehabilitation. A recent study demonstrated for the first time that cortical stimulation can enhance human cortical plasticity elicited by motor training. These results demonstrated that UDP can be promoted by synchronous Hebbian stimulation of the motor cortex. Performance time of each subtest with cortical stimulation (black bars) and placebo stimulation (grey bars) relative to baseline (white bars) is shown in a representative patient. Subtests consist of turning cards (exemplarily shown in the lower row), picking up small objects, mimicking feeding by putting beans with a spoon in a can, stacking checkers, and lifting light and heavy cans is shown. Note the improvement of performance time during tDCS compared to placebo stim- ulation, indicating that cortical stimulation of the affected hemisphere improved functional motor skills of the paretic hand in this particular patient (modified from Hummel et al. Results depicted so far have demonstrated that cortical stimulation applied to one site can enhance excitability or plasticity at that site. Additionally, cortical stimulation applied to one site can induce distant effects on cortical function and behavior. It has been proposed that this balance may be disturbed in patients with cortical lesions such as stroke. Indeed, an abnormally high interhemispheric inhibitory drive from M1 in the intact hemisphere to M1 in the affected hemisphere has been documented during generation of a voluntary movement by the paretic hand. Therefore, it is conceivable that one way to improve motor function in the paretic hand is to decrease motor cortical excitability in the ipsilateral, intact motor cortex (with the purpose of reducing abnormal inhibition from the intact to the affected hemisphere), a hypothesis under investigation. In summary, animal models and human studies in healthy volunteers and stroke patients suggest that cortical stimulation may potentially become an adjuvant to improve motor function and enhance the beneficial effects of motor training in patients with brain lesions. Improved understanding of the way in which somatosensory input influences motor function led to the development of novel rehabilitative interventions. One example is constraint-induced movement therapy, a strategy consisting of immobi- lization of the intact hand of stroke patients associated with intensive practice performed with the weak hand. This intervention may enhance functional recovery in patients with motor deficits following a stroke. The combination of constraint and practice in these patients may result in a reduction of exaggerated interhemispheric inhibition from M1 in the intact hemisphere to M1 in the affected hemisphere. CONCLUSIONS The somatosensory and motor cortices are highly interconnected, operate in var- ious settings of learning and skill acquisition, and experience constant reorgani- zation in response to environmental challenges or lesions. Acute and chronic deafferentation, somatosensory stimulation, and cortical stimulation can modulate plasticity in both cerebral hemispheres. Improved understanding of these plastic changes has recently raised the exciting hypothesis of utilizing these tools to modify function after brain lesions such as stroke, hopefully evolving to the development of new strategies in neurorehabilitation.

Swenson, Scott Haldeman and Simon Dagenais Complementary Therapies in Neurology: An Evidence-Based Approach Edited by Barry S. Oken ISBN 1-84214-200-3 Copyright © 2004 by The Parthenon Publishing Group, London INTRODUCTION Over the past decade, the awareness of the medical community has been raised regarding the extensive and growing utilization of what has come to be called complementary and 1 2 alternative medicine (CAM). Eisenberg and colleagues demonstrated an increase in the use of CAM therapies from 33. Among those using CAM therapies, the probability of visiting an alternative medicine practitioner (as opposed to using a CAM therapy without a practitioner) increased from 36. Over these 7 years, the total number of visits to alternative medical practitioners was estimated to have increased by 47. This figure is comparable with the total projected out-of-pocket expenditure for all US physician services. One of the more common reasons is a perceived limitation in conventional medical practice. Nowhere is this more obvious than in the management of back and neck pain, which exist in epidemic 4 proportions in the Western world and which, in most cases, have no completely satisfactory medical treatment. Therefore, many patients consulting CAM practitioners are doing so for back and neck complaints, with several CAM therapies being viewed as 5 6 potentially effective for these conditions. A recent study by Wolsko and associates reported that, among those with back or neck pain, 53. Additionally, the percentage of patients who had consulted an alternative medical provider about their condition (34. Among the complementary therapies, the physical methods (chiropractic, massage, yoga, acupuncture, osteopathy) were the most widely used. Patient satisfaction with CAM therapies appears to be an important factor in their increased popularity, with 47. The Complementary therapies in neurology 288 CAM therapies with the highest perceived helpfulness were those utilizing physical methods, with chiropractic at 60. SCOPE OF THE REVIEW Although many CAM therapies have been applied to the treatment of back and neck pain, this chapter focuses on those methods that are most commonly used and enjoy the broadest support in the literature, namely acupuncture, massage, mobilization and manipulation. Following our review of the physical methods of CAM therapies, a brief synopsis will be presented on the use of nutritional supplements, homeopathy and magnets, which are often used by the public for back and neck pain. ISSUES IN COMPLEMENTARY AND ALTERNATIVE THERAPY RESEARCH There are at least four main methodological barriers to overcome when attempting to study CAM therapies. The first is that most CAM therapies are in fact elements of broader healing systems based on a unique theoretical construct and system of analysis, rather than stand-alone treatments. Chinese medicine) may neither do justice to that intervention nor reflect its true use by practitioners.
