What Researchers Did
Researchers reviewed the current evidence regarding hyperbaric oxygen therapy (HBOT) in both experimental and clinical stroke settings.
What They Found
Numerous basic and clinical studies since the 1960s have indicated beneficial effects of HBOT on neurological outcomes after stroke, illustrating mechanisms such as improved cerebral oxygenation, anti-inflammation, and neural regeneration. However, the evidence for HBOT in human stroke is not yet sufficient due to a lack of randomised double-blind controlled clinical studies. Furthermore, there are currently no uniform criteria for the optimal dose and duration of HBOT sessions.
Canadian Relevance
This study has no direct Canadian connection, as it did not involve Canadian researchers, institutions, or patients.
Study Limitations
The primary limitation highlighted is the insufficient number of randomised double-blind controlled clinical studies on HBOT in human stroke, leading to a lack of uniform treatment criteria.
