To whom it concerns: I am a ultrasound technologist. We went to school for at least two years. I don't know how many hours to prepare the bored exam. When I got a job from our hospital, The orientation is three days to getting to know the hospital, then whole week to get to know the departmental ,this is the 66 hour already before we start to  touch the patient. So imagine?if the patient is your family or is your daughter or your mom, would you let a somebody just has been trained 50 hours use the dry needle on their body with out any professional faculty supervise?
