About this study
The objective of this study is to assess the functionality of a sensory stimulation device that uses mechanical vibrations and low-intensity electrical currents to deliver proprioceptive feedback to stroke patients regarding their movements.
- Conditions
- Healthy Subjects or Volunteers, Chronic Stroke
- Being tested
- Afferent stimulation
- Keywords
- Afferent stimulation, Proprioception
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Afferent stimulationDevice
Stimulation applied through mechanical vibration or low-intensity electric currents
| Study group | Role | What they receive |
|---|---|---|
| Healthy subjects | Experimental | Intervention applied to healthy subjects Receives: Device: Afferent stimulation |
| Stroke patients | Experimental | Stimulation applied to stroke patients Receives: Device: Afferent stimulation |
What is being measured
The primary outcome is the main question the study is designed to answer.
Motor illusion
Motor illusion is evaluated by instructing the patient to replicate the movement they experienced in the contralateral limb. Inertial sensors will be placed in such limb to acquire the movement performed by the subject.
Measured: Periprocedural

Questions about this trial
What is this clinical trial studying?
A study testing Afferent stimulation in people with Healthy Subjects or Volunteers and Chronic Stroke, run by Julio S. Lora Millán at 1 site in Spain.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 16 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 20 Jul 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Julio S. Lora Millán, PhD in Automation and Robotics (914880000 ext. 4584, julio.lora@urjc.es), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Motor illusion (time frame: Periprocedural). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Jul 2025; AzTrials last refreshed its copy on 6 Nov 2026.
