What Researchers Did
Researchers conducted a prospective matched case-control study involving 71 patients with Type 2 diabetes and lower-extremity neuropathy to examine the impact of hyperbaric oxygen therapy on vasomotion.
What They Found
Of the 71 patients, 39 received 15 sessions of hyperbaric oxygen therapy, while 32 served as controls. Patients without foot ulcers showed significant increases in respiratory, cardiac, and total spectral activity of flowmotion on the ankle and increased cardiac and total spectral activity on the dorsum of the foot. In contrast, patients with diabetic ulcers experienced a decrease in total spectral activity on the dorsum of the foot.
What This Means for Canadian Patients
Canadian patients with Type 2 diabetes and lower-extremity neuropathy might experience improved blood vessel function from hyperbaric oxygen therapy, especially if they do not have foot ulcers. However, the therapy's effect on vasomotion appears different in those with existing diabetic ulcers, requiring careful clinical assessment.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
The study's findings are limited by its relatively small sample size and the specific population studied, which may affect generalizability.
