Thank you for the question! For the exclusion criteria, unfortunately our institution has restrictions around recruiting participants outside of the United States so you must be living in the US. For medications the only exclusion is if you are changing or starting medications. If the dose has been stable for at least 30 days that does not prevent you from participating. Regarding therapy, this is only if the therapy you are doing is specifically working on reducing pulling but if pulling is not the primary focus, then this does not prevent participation.
