Chronic Stroke Survivors Clinical Trial
Official title:
Improving Recovery After Stroke Via Electrical Stimulation of Proprioceptors
The overall objective of the study is to test whether the use of small electrical currents to stimulate proprioceptors of the upper limb has potential for improving robot-assisted upper-limb rehabilitation in stroke survivors.
Study participants will be instructed to perform upper-limb movements using a system
designed for upper-limb rehabilitation (Armeo Spring by Hocoma AG). The system provides
subjects with unloading of the stroke-affected arm thus facilitating the performance of
upper-limb movements. The system will be used to track the movements of the stroke-affected
arm. Simultaneously, a custom-designed system (a prototype developed by the investigators)
will be used to deliver small electrical currents to the arm. We hypothesize that the
currents delivered to the arm will improve the accuracy of the movements performed by study
participants.
To assess if delivering small currents to the arm has an effect on the accuracy of the
movements performed by the study participants, they will receive actual stimulation for some
trials and sham stimulation for other trials. Because the investigators will deliver very
small currents, study participants will be unable to perceive such currents and hence tell
if they are performing the movements while receiving actual or sham stimulation. By
comparing trials performed while subjects receive actual stimulation with trials performed
while subjects received sham stimulation, the investigators will determine if the
stimulation has an effect on the accuracy of the movements performed by the subjects.
It is worth noticing that the investigators collected primary outcome data to assess changes
associated with the use of actual stimulation vs sham stimulation. Data during a follow-up
session was also collected, but not for the purpose of collecting outcome measures.
