Plain English

Harch et al. (2017, Medical Gas Research) is a case-control study of HBOT for mild traumatic brain injury persistent post-concussion syndrome and post-traumatic stress disorder. The paper is one of Dr. Paul Harch's most-cited contributions to the HBOT TBI/PTSD literature. The previous Saturate site copy for this entry overstated specifics not directly traceable to the verified PubMed record — that copy has been retired pending a clean re-paraphrase from the actual abstract. Bibliographic fields (title, authors, journal, year, DOI, PMID) are now PubMed-verified; the long-form summary will be rewritten in the next verified-fetch pass. Source: PubMed PMID 29152209.

Key findings

What the trial documented.

  • Case-control study examining HBOT for mild TBI persistent post-concussion syndrome and PTSD
  • Published in Medical Gas Research, October 2017
  • See PubMed PMID 29152209 for full abstract — site copy will be re-paraphrased post-verified-fetch

Persistent post-concussion syndrome (PPCS) from mild traumatic brain injury, often alongside PTSD, is common among post-9/11 veterans and has limited treatment options. Harch and colleagues assessed whether hyperbaric oxygen could help.

What the study looked at

This case-control study enrolled 30 military subjects aged 18-65 with PPCS, with or without PTSD, from one or more blast-induced mild-to-moderate brain injuries at least a year old. Measures included symptom lists, physical exam, neuropsychological and psychological testing (on 29 subjects after one dropout), and SPECT brain imaging before and after treatment.

What it found

The authors reported improvements across symptom, cognitive, and psychological measures following HBOT, accompanied by changes on SPECT imaging.

How strong is the evidence?

As a small case-control study without a sham-controlled randomized design, this is preliminary, hypothesis-generating evidence. The earlier site copy for this entry overstated specifics; this version is paraphrased directly from the published abstract.
