Who can take part

AI summary

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for adults who had a stroke at least 3 months ago, have trouble sensing arm position, and can bend and straighten the elbow on their own.

Age
19 years or older
Sex
Men and women
Disease stage
Chronic stroke (ischemic or hemorrhagic), confirmed by CT or MRI, with onset at least 3 months before.
Biomarker or test result
Proprioceptive sensory deficits (trouble sensing the position of the arm). Must be able to voluntarily flex and extend the elbow joint.

Main reasons for not taking part

  • Severe pain when moving the elbow
  • Elbow contracture, spasticity, ataxia, musculoskeletal disorders, fractures, non-healing ulcers or open wounds
  • Progressive or unstable stroke
  • Unilateral neglect
  • Other severe neurological disorders, major psychiatric disorders (such as major depressive disorder, schizophrenia, bipolar disorder or dementia), or a pacemaker

About the trial

What the trial wants to find out

The investigators aim to develop sensory transformation and augmentation technologies that minimize the impact of proprioceptive errors, thereby significantly enhancing motor learning and rehabilitation of the upper limbs. This study is designed to test proprioceptive error compensation techniques in stroke patients.

Read full original descriptionShow less

The human nervous system often receives mismatched information from vision and proprioception during upper limb control, resulting in conflicting sensory inputs that limit the effectiveness of motor learning. In other words, real-time sensory feedback - a critical component of motor learning in the nervous system - is not reliably delivered. Therefore, this study seeks to resolve sensory conflicts by providing additional sensory information through electrical stimulation, with the goal of dramatically improving the effectiveness of motor learning.
