Anxiety and fainting (somatic responses)

Hello! During the recent training (Nov. 2023), it was mentioned that SPACES is trialing using the treatment program for children who experience somatic response with anxiety. I am supporting someone who faints (there has been extensive medical testing and it has come back clear). Is there an adaptation that could be included in using SPACES for these cases and if so, how might that look? And even more specific, if this is a case that might be able to join the clinical trial.... I'd be all about seeing if we could be a part of it!
