Ultrasound-guided needle nerve stimulation to improve walking after stroke

Official title: Ultrasound-Guided Percutaneous Neuromodulation Protocol to Improve Gait Rehabilitation in Patients Who Have Suffered a Stroke. Clinical Trial.

Run by Universidad de Zaragoza · NCT07196878 · Data updated 2026-11-12

This trial will test whether adding ultrasound-guided percutaneous nerve stimulation to regular physiotherapy helps adults who have had a stroke walk faster and move better.

Is this trial a fit for you?

Likely a good fit

Adults aged 18–70 who are in the subacute or chronic phase of stroke (at least three months post-event), able to walk independently for short distances (about 10 meters), currently receiving physiotherapy, and able to consent are ideal candidates.

Probably not a fit

People with needle phobia, uncontrolled bleeding disorders, active systemic inflammatory disease, recent invasive physiotherapy, pregnancy, certain skin or oncologic conditions, or those unable to attend site visits or walk independently are unlikely to benefit from this protocol.

What this trial studies

This interventional study compares standard physiotherapy alone versus physiotherapy plus ultrasound-guided percutaneous neuromodulation (PNM) targeted to the sciatic and common peroneal nerves. About 30 adults at least three months after stroke who can walk independently for short distances will be enrolled and receive usual rehabilitation while the experimental group also receives needle-based nerve stimulation under ultrasound. Stimulation sessions use a fine needle placed near the nerve with brief electrical pulses (e.g., 10 Hz for short trains) alongside conventional strength, mobility, and balance exercises. Outcomes include walking speed, lower-limb strength, spasticity, balance, functional mobility, and health-related quality of life over the treatment period.

Why it matters

Potential benefit: If successful, the approach could speed walking recovery, increase leg strength, reduce spasticity, and improve balance and daily function for some stroke survivors.

How similar studies have gone: Small pilot studies and other peripheral neuromodulation approaches have shown promising but limited improvements in motor recovery after stroke, while ultrasound-guided percutaneous nerve stimulation remains a relatively novel and not yet widely validated technique.
