Summary

What Researchers Did

Researchers used functional MRI to study how hyperbaric oxygen therapy affected brain activity and hand movement recovery in one patient with severe chronic stroke.

What They Found

After 60 daily HBOT sessions, the patient's Fugl-Meyer assessment (FMA) score for motor function improved from 17 (severe impairment) to 31 (moderate impairment). Functional MRI showed increased brain activation in motor areas and a decrease in the lateralization index from 1 to 0.63, indicating more brain activity in the opposite hemisphere. The study also found increased connectivity between brain hemispheres and between different brain networks.

Canadian Relevance

No direct Canadian connection identified.

Study Limitations

The main limitation of this study is that it is a case report, meaning the findings are based on only one patient and may not apply to others.
