NCT ID: NCT03237754 Terminated - Randomized Clinical Trials

Neurostimulation in Chronic and Episodic Migraine

Start date: October 1, 2016
Phase: N/A
Study type: Interventional

Currently, successful prevention of migraine is not sufficiently achieved by (prophylactic) drug therapy. In contrast, neurophysiologically guided treatments might provide an alternative avenue, since these can normalize brain alterations without side effects. Transcranial direct current stimulation (tDCS) appears useful in the acute and prophylactic treatment of migraine, probably because of its modifying and re-balancing influence on neuronal activity. Yet, to test for the efficacy of tDCS in a clinically acceptable way, it is necessary to apply not only tDCS but also a "sham" placebo, which is often neglected in tDCS stimulation studies. Further, tDCS needs to be applied in a large (n > 20) sample of well-defined migraine patients, which would be advantageous, compared to previously published work. Monitoring sources of regional neuronal alterations in migraineurs prior and after tDCS is essential to investigate physiological mechanisms of tDCS. There is an increasing interest towards non-pharmacological treatment alternatives for migraine (and headache disorders) with reduced side effects to established prophylactic medications. The primary outcome of this project is to demonstrate that repetitive sessions of neurostimulation lead to a significant and permanent reduction of the primary symptom severity (i.e. migraine attacks) for patients suffering from chronic and episodic migraine. Since neurostimulation tools are nowadays accepted as therapeutic tools, our study might provide evidence that tDCS can be a non-pharmacological alternative for treating migraine.

NCT ID: NCT03060460 Terminated - Ultrasound Clinical Trials

Ultrasound Guided Insertion of Sheath Before Angiography or Angioplasty

ACCESS-II
Start date: April 26, 2017
Phase: N/A
Study type: Interventional

The study evaluates whether routine use of ultrasound for sheath insertion during radial or femoral angiography or angioplasty has any impact on: number of punctures, patient discomfort, procedural length, successfull procedure or ideal vessel puncture.
