If you resist having therapy and think it is useless, it will be. This goes for any kind of therapy whether for a speech problem or a physical problem. Those who have a qualified speech therapist and who learn the techniques and practice them will obtain better speech. Those who have had joint replacement and go to physical therapy and follow the instructions while at home will have mobility again. Those who don't will continue on as they were or be immobilized and bed ridden. It is a choice!
