What Researchers Did
Researchers conducted a randomized crossover study with 17 healthy volunteers to investigate if hyperbaric oxygen therapy could attenuate central sensitization, measured by secondary hyperalgesia areas, induced by a first-degree thermal skin injury.
What They Found
Overall, hyperbaric oxygen therapy significantly attenuated secondary hyperalgesia areas (SHAs), a measure of central sensitization, compared to control sessions (P=0.011). Specifically, in the nine volunteers who started with the control session, HBO2 significantly reduced SHAs (P=0.004), though no difference was seen in the eight volunteers who began with HBO2.
What This Means for Canadian Patients
This research suggests that hyperbaric oxygen therapy could potentially help reduce pain sensitivity in Canadian patients experiencing central sensitization, such as after burns or other injuries. Further research is needed to determine its clinical applicability for managing chronic pain conditions.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
A limitation is the small sample size of 17 healthy volunteers, and the observed attenuation was not consistent across all study arms, suggesting potential order effects.
