Hi, Little Acanthaceae. It's been a while since I viewed any of your valuable posts. I need a referral for more information about rhythmic tapping. You did provide some clinical information but I really need more such as. the physiological locus of the brain deformity. This is very interesting because it's an issue I deal with. I'm not sure my neurologist is aware of the issue. Can you refer me further to information? The Reddit forum values your accurate input and this information would be pertinent to many who aren’t aware of the neurological aspects of stuttering and attribute it to psychological issues. Best, Sue
