What the trial is, and whether it could suit you

The purpose of this study is to confirm the analgesic effect of tDCS in neuropathic chronic pain, to estimate the importance and the duration of this effect, and to improve its efficiency by the use at home. It is established that the repetition of the sessions of cortical stimulation over a week improves their analgesic efficacy. However, this effect does not exceed a few weeks and is much lower than that of the stimulation implanted surgically. Implanted stimulation operates periodically, several times a day, and this "repetition of doses ", akin to the regular taking of a medicine, may explain its longer efficacy for pain relief which, may extend over several years (André-Obadia and al 2014). No study at this date has estimated the long-term effect of non-invasive stimulation when is also periodically repeated on a daily basis, over several weeks.
