What Researchers Did
Researchers retrospectively assessed long-term outcomes 5 to 8 years after injury in 133 patients with moderate-to-severe traumatic brain injury who received HBOT during inpatient rehabilitation, analyzing the relationship between number of HBO sessions and functional recovery.
What They Found
62.4% of patients achieved mild or no disability at 5 to 8 year follow-up. Statistical modeling suggested approximately 14 HBOT sessions were optimal for moderate TBI and 21.6 sessions for severe TBI. More sessions beyond the optimal range were associated with worse prognosis.
What This Means for Canadian Patients
TBI is one of the most common causes of long-term disability in Canada. This study suggests HBOT during rehabilitation may reduce disability years later, but raises an important caution: excessive sessions may be counterproductive. Treatment should be individualized rather than pursuing as many sessions as possible.
Canadian Relevance
No direct Canadian connection identified. Relevant to the estimated 400,000 Canadians living with TBI-related disability.
Study Limitations
This retrospective Chinese study may not reflect rehabilitation contexts in Canada; the optimal session numbers were derived from statistical models applied to a non-randomized dataset.
