The NOI group has a overall treatment program, but it's my understanding the specific protocol depends on the person. In PT, my therapist would use different fabrics, like a wash cloth, sometimes unexpectedly. In OT, I use the corn husk machine and different textures on a stick. But how long I do any of those depends on whether it's a good or bad day, how long I've been doing it, etc. The most important thing is to try to use the affected area as much as possible as normally as possible. The more normal signals the brain gets, the better. Please go at your own pace though. With my foot, it took much longer to resume normal activity than it did in my hand.
