we do it with both our sons, they are completely opposite with their sensory issues, one is sensory seeking and the other sensory avoiding, it has helped the most with my sensory avoiding son, It has not cured him, but it allows him to tolerate touch better. I don't thing you can cure something like that but I do believe it improves a "tolerance" level. My sensory seeking son we don't know about yet, he is very hard to brush because it tickles him A LOT. So far he is the same, but I admit I am not always as regular about his brushing
