One of my other more involved little girls with hemiplegic CP, had quite high tone in her affected arm and leg. I noticed that after about a month or so of engaging in the RMT movements every other day, there was a very noticeable decrease in her muscle tone in her affected hand. Instead of being very tight and fisted it was relaxed most of the time! This is a similar effect to what BOTOX does to a muscle to relax it. So we worked on targeting specific muscles to strengthen them!
Also, I've been noticing, I have shown the program to some parents to complete with their child. Well I have noticed changes in the way the kid's hands look (more muscle tone and look more "normal") and how they are able to use their hands in functional activities! I commented to one mom about this and she said she notices the same thing! She said her son is now doing things such as opening bottes, something he's never been able to do! Pretty COOL!
