New study aims to predict who gets muscle stiffness after stroke
NCT ID NCT06055725
First seen Jun 25, 2026 · Last updated Sep 04, 2026 · Updated 4 times
Summary
This study follows over 1,000 adults who had their first stroke to see how many develop spasticity—a condition where muscles become stiff or rigid—within the first year. Researchers will monitor participants and create a best-practice guide for doctors to spot and treat this common complication. The goal is to improve care and quality of life for stroke survivors.
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 study could establish a standard guideline for monitoring post-stroke spasticity, helping doctors identify patients who need treatment earlier.
- What could go wrong
- This is an observational study, not testing a new treatment. It may not change outcomes directly, and results might not apply to all stroke patients.
This is an AI summary of the original study and may miss details. Read our disclaimer.

Inclusion Criteria: * Participant must be aged 18 to 90 years at the time of providing informed consent * First-ever clinical stroke, defined according to World Health Organization criteria as rapidly developing clinical signs of focal (at times global) disturbance of cerebral function lasting more than 24 hours, within the past 4 weeks; * Confirmed paresis of the arms and/or legs which does not resolve within 1 day, according to the NIHSS score (a score of \> 0 on Question 5 or 6 of the scale) within 2 weeks after the stroke * Capable of giving informed consent which includes compliance with the requirements and restrictions listed in the ICF and in this protocol Exclusion Criteria: * Upper or lower extremity functional impairment prior to stroke per investigator judgement (e.g., modified Rankin Scale \>2); * Presence of significant/major neurological impairment that might affect muscle tone (other than limb paresis); * Severe multi-impairment or diminished physical condition before stroke that could have caused paresis/spasticity/motor deficit per investigator judgement; * Life expectancy of less than 12 months as a result of severity of stroke or other illnesses (e.g. cardiac disease, malignancy, etc.) * Participation in any interventional study
