While research suggests a benefit of hyperbaric oxygen therapy (HBOT) for neurologic injury, controlled clinical trials have not been able to clearly define the benefits. To investigate the effects of HBOT on physical and cognitive impairments resulting from an ischemic stroke. Using a within-subject design a baseline for current functional abilities was established over a 3-month period for all subjects (n=7). Each subject then received two 4-week periods of HBOT for a total of 40 90-minute treatments over a 12-week period. Subjects completed a battery of assessments and had blood drawn six times over the 9-month total duration of the study.

Acute ischemic stroke is a leading cause of mortality and long-term disability, and profiles of endothelial progenitor cells (EPCs) reflect the degree of endothelial impairment. This study tested the hypothesis that hyperbaric oxygen therapy (HBOT) both improves the clinical short-term outcomes and increases the number of circulating EPCs and antioxidant capacity. The numbers of circulating EPCs [CD133/CD34 (%), KDR/CD34 (%)], biomarkers for oxidative stress (thiols and thiobarbituric acid-reactive substances), and clinical scores (National Institutes of Health Stroke Scale [NIHSS], Barthel index [BI],

Background and Rationale:
Cerebrovascular disease is always ranked at the top causes of death and most of hospitalized
acute stroke patients have ischemic stroke [1].
Although the mortality rate of acute ischemic stroke is less than that of hemorrhagic stroke
[1], it still results in patient disabilities and complications that often lead to
significant costs to individuals, families, and society.
Traditional treatment for acute ischemic stroke includes thrombolytic therapy by injecting
tissue plasminogen activator (t-PA) within three hours after onset of symptoms [2],
antiplatelets and/or anticoagulant agents administered within the first 48 hours. Clinically,
the narrow time window of thrombolytic therapy and coexisting contraindications limit the use
of t-PA [2]. Thus, searching for an effective supplemental treatment for acute ischemic
stroke is imperative.
Hyperbaric oxygen therapy (HBOT) is valuable in treating acute carbon monoxide poisoning
[3,4], air or gas embolism [5], facilitating wound healing [6] and has been used as an
adjuvant treatment for many neurological disorders that need further study as concussion [7]
, stroke [8,9], cerebral palsy [ 10],traumatic brain injury [ 11], cerebral air embolism
[12], Autism [13] and multiple sclerosis [14].
Indications of hyperbaric oxygen therapy recommended by undersea and hyperbaric medical
society (UHMS) [15] are 1.air or gas embolism [5], 2.carbon monoxide poisoning [3,4],
3.clostridial myositis and myonecrosis [16], 4.crush injury, compartment syndrome and other
acute traumatic ischemias [17], 5.decompression sickness [18], 6.arterial insufficiencies
[19], 7.severe anemia [20], 8.intracranial abscess [21], 9.necrotizing soft tissue infections
[22],10. refractory osteomyelitis [23], 11.delayed radiation injury [24], 12.compromised
grafts and flaps [25], 13.acute thermal burn injury [26] and 14.idiopathic sudden
sensorineural hearing loss [27].
Known mechanisms of HBOT-induced neuroprotection include enhancing neuronal viability via
increased tissue oxygen delivery to the area of diminished blood flow, reducing brain edema,
and improving metabolism after ischemia [28,29]. Furthermore, a recent study performed on a
rat suggested that upregulation of the expression of glial derived neurotrophic factor (GDNF)
and nerve growth factor (NGF) might underlie the effect of HBOT [30].
The effectiveness of use of Hyperbaric oxygen therapy in human ischemic stroke is still
controversial that need further evaluation.

To study safety, feasibility and outcomes of combining osteopathic manipulative therapies
with hyperbaric oxygen therapy in reducing the functional deficits in stroke survivors in
subacute and chronic phases post ischemic stroke. To document the same as part of a pilot
project in anticipation of further investigational studies.

Hyperbaric oxygenation (HBO₂) involves breathing 100% oxygen under elevated ambient pressure in a hyperbaric chamber, thereby dissolving oxygen in the plasma. This results in an increase of arterial partial pressure of oxygen (pO₂). Though well established in experimental studies, HBO₂ treatment for ischemic stroke is still under discussion. From 2002-2014 HBO₂ (2.2 bar, 90 minutes one/day; average number per patient: 4.7) was applied in 49 consecutive patients (32 males, 17 females, mean age: 68.8 years, range 31.2 – 83.9) with acute neurological deficit following cardiac surgery (CABG 15; combined surgery 14; valve surgery 11; aneurysm repair 8;
