Transcranial Magnetic Stimulation

The pain medicine leads so far argumentatively pain memory, if an explanation shall be given, that the goal of treating chronic pain does not “get away”, but relief and boost the quality of life is or if the compliance of the patient are strengthened to evoke not more chronicity (and thus the progression of neuro-plastic changes). So far it has been but no concept to change the memory of pain. It lacked a causal treatment approach to chronic pain. That has changed with the introduction of the modern non-invasive neuro-modulation method, the repetitive Transcranial Magnetic Stimulation (rTMS) and Transcranial direct current stimulation (tDCS = transcranial direct current stimulation). While the rTMS in pain therapeutic practice mainly in somatisierter anxiety and depression used an increasingly wide application is emerging for the tDCS. So far mainly patients treated with migraine and Fibromyalgia so, the stand-alone picture of “chronic pain illness” puts more and more in the center of the treatment indications now. How does so a treatment practically? Transcranial direct current stimulation (tDCS) can be about liquid-wetted surface electrodes (35 square inches) with a current up to 2 mA intrakraniell a sufficient flow achieve, to bring about shifts in the threshold of excitability. He even subliminal and is able to trigger still no neuronal action potentials.

Perceived only a light sparkling of the scalp. Basic mechanism of tDCS is a resting membrane potential shift of cortical neurons, depending on the polarity of stimulation in the direction of hyper – or depolarisierender. This in turn changes the discharge behavior: by anodale irritation, the cortical excitability is increased by kathodale reduced. Daily zwanzigminutiger stimulation duration for at least 5 days these changes stop at longer time, which can be interpreted, that fade perception shares from the memory of the pain. Embedded in a multimodal treatment principle, which helps prevent further chronic can be thereby sustainably improve the treatment success.

If not all details of this new process have been resolved, so can be established with certainty, but that the Transcranial stimulation represents a simple method for generating neuroplasticity low DC. It allows the noninvasive, painless, focal, selective and reversible changes in cortical excitability threshold being the length and intensity modulated.
