Pilot study following a randomized controlled trial design, designed to study the feasibility of a study with a larger sample size.~Intervention of 30 stroke participants with an evolution between 6 months and 4 years since the stroke, who are able to stand upright.~These participants will be recruited voluntarily through a campaign in social networks and with the collaboration of local associations and institutions. Once the inclusion and exclusion criteria have been reviewed, they will be randomly assigned to an intervention group and a placebo group. A double-blind recruitment system will be followed in which the physiotherapist and patients will not know whether they are receiving real or simulated stimulation, for this purpose two NESA XSIGNAL® devices will be used in double-blind mode.~Treatment of 20 sessions per patient, of 1 hour duration each, with the NESA X-Signal device.
To evaluate whether NESA microcurrents can be used as an effective treatment for various sequelae present in stroke patients, specifically in the treatment of spasticity, balance, pain; and whether it affects quality of life, performance of activities of daily living and quality of sleep.
