What Researchers Did
Researchers conducted a randomized controlled trial with 59 chronic stroke patients to evaluate if hyperbaric oxygen therapy (HBOT) could improve neurological functions and brain activity.
What They Found
Patients in both the treated and cross groups showed significant improvements in neurological functions and quality of life after 40 hyperbaric oxygen therapy sessions. No improvements were observed during the 2-month control period, and SPECT imaging confirmed elevated brain activity correlated with clinical improvements.
Canadian Relevance
This study was not conducted in Canada and does not have a direct Canadian connection.
Study Limitations
A limitation of this study is its relatively small sample size of 59 patients, which may affect the generalizability of the findings.
