Hi Khaled, that is correct. I discovered crutch 1 at the tender age of 8, my stutter was extremely mild at this point, I started stuttering properly at age 10. What I can say, is that crutch 1 definitely kept me from becoming a severe PWS. It is one of the easiest crutches to master, and nobody will even be aware that you are using it. Have you watched some of our coaching videos where we drill crutch 1? This is a really great place to start.
