BDSM might be considered a good _clinical_ treatment, but any therapeutic value BDSM has in "natural" options is probably serendipitous and very person without broader applicability.
I suppose that BDSM may have therapeutic potential, but the conditions to make it valuable would be very weird, possibly to the level of destroying the value.
For of inpatient therapy for PTSD. basis instance, there were several studies released during the last few years looking at the use of presently prohibited psychedelics (notably MDMA and ketamine, but also psilocybin) as the. They have been quite effective.
All the treatment methods analyzed so far need the individual to have completed therapy in advance with two "witnesses" (we'd say referees) as well as the official treating psychiatrist. As folks normally do during psychedelic trips the individual is not left to free associate.
They are guided by the witnesses into reliving the upheaval that produced the PTSD trigger. The witnesses make sure they view it in the greatest mild possible.
The theory is that the psychedelic lets the patient to fully relive the minute in a safe environment and the witnesses reassuring them that everything is great which resets the neuro trail which developed the PTSD cause.
I've no idea how you would fit some thing like BDSM into a responsible, controlled therapeutic system, but this is most likely the area from which to begin building the concept.
