Shai Efrati has conflicts, he is the director of the Hyperbaric Oxygen Institute at the Assaf Harofeh Medical Center.
Without reading the complete article I wouldn't trust this because 6 of them work for the
Hyperbaric Oxygen Institute. They believe because they have to believe.
The way to objectively prove this would be fMRIs before and after. You would be able to see lit up areas that were formerly dark. So simple to do but why isn't it done?

Abstract
Background
Recovery
after stroke correlates with non-active (stunned) brain regions, which
may persist for years. The current study aimed to evaluate whether
increasing the level of dissolved oxygen by Hyperbaric Oxygen Therapy
(HBOT) could activate neuroplasticity in patients with chronic
neurologic deficiencies due to stroke.
Methods and Findings
A
prospective, randomized, controlled trial including 74 patients (15
were excluded). All participants suffered a stroke 6–36 months prior to
inclusion and had at least one motor dysfunction. After inclusion,
patients were randomly assigned to "treated" or "cross" groups. Brain
activity was assessed by SPECT imaging; neurologic functions were
evaluated by NIHSS, ADL, and life quality. Patients in the treated group
were evaluated twice: at baseline and after 40 HBOT sessions. Patients
in the cross group were evaluated three times: at baseline, after a
2-month control period of no treatment, and after subsequent 2-months of
40 HBOT sessions. HBOT protocol: Two months of 40 sessions (5
days/week), 90 minutes each, 100% oxygen at 2 ATA. We found that the
neurological functions and life quality of all patients in both groups
were significantly improved following the HBOT sessions while no
improvement was found during the control period of the patients in the
cross group. Results of SPECT imaging were well correlated with clinical
improvement. Elevated brain activity was detected mostly in regions of
live cells (as confirmed by CT) with low activity (based on SPECT) –
regions of noticeable discrepancy between anatomy and physiology.
Conclusions
The
results indicate that HBOT can lead to significant neurological
improvements in post stroke patients even at chronic late stages. The
observed clinical improvements imply that neuroplasticity can still be
activated long after damage onset in regions where there is a brain
SPECT/CT (anatomy/physiology) mismatch.
