What Researchers Did
Researchers investigated the effects of hyperbaric oxygenation on motor and sensory peripheral nerve conduction in nine diabetic patients with distal symmetrical polyneuropathy.
What They Found
Initial electrophysiological studies in nine diabetic patients revealed enlarged terminal latencies, slowed conduction velocities, and reduced distal amplitudes. Six months after hyperbaric oxygen treatment, motor and sensory fibers of the median nerve showed slower conduction velocities, increased distal latency, and progressively decreased sensory action potential amplitudes, suggesting no benefit for large diameter peripheral fibers.
What This Means for Canadian Patients
Canadian patients with diabetic neuropathy should be aware that hyperbaric oxygen treatment may not improve nerve conduction, particularly in large diameter peripheral nerve fibers. Current evidence from this study does not support hyperbaric oxygen as an effective therapy for reversing electrophysiological abnormalities associated with this condition.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
A significant limitation of this study is its very small sample size of only nine patients, which limits the generalizability of the findings.
