What Researchers Did
Researchers conducted a systematic review and meta-analysis of 27 randomised clinical trials involving 2250 participants to assess the efficacy and safety of hyperbaric oxygen therapy for post-stroke depression.
What They Found
Patients receiving hyperbaric oxygen therapy had a significantly higher response rate (69.4% vs 51.2%, odds ratio = 2.51) and significantly reduced Hamilton Depression scores (weighted mean difference = -4.33 for HAMD-17). Additionally, HBOT improved neurological deficit scores (e.g., NIHSS weighted mean difference = -2.77) and physical disability (Barthel Index weighted mean difference = 10.68).
Canadian Relevance
This study does not have a direct Canadian connection as none of the included trials or authors are identified as Canadian.
Study Limitations
A limitation of this meta-analysis is the potential for heterogeneity among the included studies and the quality of the primary research from which data was extracted.
