I do not know how well this applies to Parkinson's. If anyone has experience with this modality please comment:
“I needed to be able to retrain these capacities. Now it wasn't going to be easy. I understood that and it was incredibly frustrating. And there were days that I was so upset and disappointed and mad. Because I wasn't getting anywhere fast. This is where I really needed to learn to trust. I needed to learn practice and I needed to learn perseverance. I realized I was about to convert theory into practice into reality. That's what I did in those six months. Every day I went outside with the help of my mother sat on the grass and just became really present. This is when I learned what mindfulness and a meditation really was. Before that I would never slow down for five minutes to do anything like that. I never had time to do that. All of a sudden I had all this time. I knew that it was important to calm my whole nervous system down and to create an inner peace that would allow my body to heal. To remember the capacities that I was able to do prior to surgery.
“So every day I would sit out there in nature. I would calm my nervous system down and I would rehearse mentally what it was like to speak clearly. What it was like to stand and walk with steadiness. So it was this mental rehearsal over and over again and again drawing from my studies in Neuroscience. The way neuroplasticity works is that you fix your intentional focus on a pattern that you're wanting to create. It takes focused attention, then it takes repetition and then positive reinforcement. So every time you get it right you make sure you reinforce that with “Yay I did it”. Something to get that dopamine level up in the brain to give you a sense of reward to keep going, to keep growing, to not give up. I knew that if I could do that every single day I was going to get well. There was just this knowing, because I knew what to do and the only person that was going to stop me was me.
“So I realized for the first time how powerful we are. What we're really capable of right between our ears. But we're not taught how to use it. We're not taught how to do it. That's really become my mission now to really show people what we are capable of doing. I guess these experiences have come to me to demonstrate that will and that power that we do have.”
