About this trial
Supplementing or augmenting sensory information to those who have lost proprioception after stroke could help improve functional control of the arm. Thirty subjects will be recruited to a single site to evaluate the ability of supplemental kinesthetic feedback (a form of vibrotactile stimulation) to improve motor function. Participants will be tested in performing reaching movements as well as more functional tasks such as simulated drinking from a glass
Eligibility criteria
Qualifiers
stroke survivors who can perform our stabilization and grip modulation tasks and who
had a single ischemic or hemorrhagic stroke of the middle cerebral artery (MCA) in the chronic state of recovery (> 6 months post-stroke).
ability to give informed consent and be able to follow two-stage instructions.
mild-to-moderate motor impairment as assessed using the upper extremity (UE) portion of the Fugl-Meyer Motor Assessment (FM); i.e., UE-FM score between 28 and 50 (inclusive) out of a possible 66.
Disqualifiers
Inability of subjects to give informed consent or follow two-stage instructions.
subjects with a bleeding disorder.
subjects with fixed contractures or a history of tendon transfer in the involved limb.
subjects with a diagnosis of myasthenia gravis, amyotrophic lateral sclerosis or any disease that might interfere with neuromuscular function.
