Which countries run stem-cell trials for Stroke Recovery?

Country distribution

A study with sites in several countries is counted once per country, taken from the location block of each registry record.

What the map means for Stroke Recovery

Registrations follow stroke units with imaging and standardised outcome scoring. Rehabilitation intensity varies enormously between countries, and it is a stronger determinant of recovery than any cell product currently on offer.

Where recruitment is actually open

What travelling for a trial actually involves

Travelling to a trial site is not like booking a treatment package. Sites enrol people they can follow up, which usually means repeated visits over months, local imaging or bloods, and an emergency route if something goes wrong. Ask about all three before booking anything.

Multi-country studies, named

Registered studies with sites in more than one country — the clearest evidence of collaboration rather than a single-centre series.

Why trial geography is not a shortlist

Where studies happen reflects who funds and who authorises them. Treating that as a ranking of care quality confuses the research system with the treatment market, two things that overlap far less than medical-tourism marketing implies.

Before treating geography as a shortlist, read the legality overview by country and what "best country" actually means here.

When these studies started

Registrations by start year since 2020: 2020 (4), 2021 (6), 2022 (4), 2023 (4), 2024 (4), 2025 (7), 2026 (8), 2027 (1). Activity for this condition spans 2005 to 2027, which shows whether interest is growing, flat or past its peak.

Frequently asked

Which countries run stem-cell trials for Stroke Recovery?

Sites are registered in 22 countries; the largest is China (~31% of country mentions, 2026-08-29).

Does a country with many trials mean better treatment there?

It does not follow. A country can host many trials and still have an unregulated commercial sector selling something quite different to visitors.

Are trial sites and commercial clinics the same thing?

Rarely. Academic trial sites and the private clinics advertising to medical tourists are typically separate organisations with different oversight.
