Recruiting NA Stroke

New treatment option for Stroke

Official title The Application of Wide Pulse High Frequency Neuromuscular Electrical Stimulation in Disorders Associated With Motoneuron Hyperexcitability

ClinicalTrials.gov ID: NCT05908214

What this study is testing

What it's testing
In the present project, the investigators aim at proposing innovative ways of investigating spinal motoneuron hyperexcitability to counteract the associated impairments by using wide pulse high frequency neuromuscular electrical stimulation (WPHF NMES) in various populations. The investigators will use WPHF NMES contractions as a model to gain insights into the mechanisms underlying muscle cramps, restless legs syndrome or stroke-induced spasticity as there is evidence that they share common underlying mechanisms.

  • The urge to move or unpleasant sensations begin or worsen during periods of rest or inactivity such as lying or sitting.
  • The urge to move or unpleasant sensations are partially or totally relieved by movement, such as walking or stretching, at least as long as the activity continues.
  • The urge to move or unpleasant sensations are worse in the evening or night than during the day, or only occur in the evening or night. When symptoms are severe, the worsening at night may not be noticeable but must...
