Hyperbaric Oxygen

Similar to depression, studies assessing the impact of HBO on anxiety following SCI are limited and the mechanisms of action are not well understood. A single study has assessed the impact of HBO on symptoms of anxiety following SCI.

Discussion

In a randomized controlled trial, Feng et al. (2017) evaluated the effectiveness of hyperbaric oxygen compared to psychotherapy or standard rehabilitation on anxiety symptoms. The study found a significant difference in levels of anxiety among those that received HBO compared to the standard rehabilitation group. No significant difference was seen between HBO and psychotherapy.

Conclusion

There is level 1b evidence that hyperbaric oxygen may improve symptoms of anxiety post SCI.
