Better electrode placement could sharpen stroke rehab insights
NCT ID NCT07387328
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study aims to validate new guidelines for placing surface EMG electrodes on the calf muscles of people who have had a stroke. Researchers will compare the new EPICA guidelines with standard SENIAM guidelines using ultrasound to see which placement gives more accurate muscle activity readings. Twenty stroke survivors will participate, and some will also walk or do heel raises to test signal quality. The goal is to improve how muscle function is measured during rehabilitation.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could lead to more accurate muscle activity measurements in stroke survivors, improving rehabilitation assessments.
- What could go wrong
- This is a small, early-stage validation study with only 20 participants, so results may not apply to all stroke survivors. It does not test any treatment.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Adult individuals who have experienced a stroke (CVA or cerebrovascular accident). * Have no other neurological disorder. * Are able to lie in the prone position for approximately one and a half hours. * Are able to walk without shoes for the walking component (only applicable to participants who will perform walking). The use of an assistive device such as a walking stick (or similar) is permitted. Exclusion Criteria: * Presence of other neurological or orthopedic conditions that may influence the measurements and results (e.g., Parkinson's disease, peripheral neuropathy of the lower limbs, severe ankle osteoarthritis limiting range of motion, etc.). * Having undergone a surgical intervention on the hemiparetic lower leg (e.g., ankle joint arthrodesis, etc.). * Severe cognitive impairments that prevent understanding participation in the study (assessed using the AbilityQ).
