I'm curious as to how you use the "Silent Coach" to improve gait. I assume you are talking about gait issues in PD.

PS, I discovered, by going back to your earlier posts that you used this device to "unfreeeze" by triggering the vibrator yourself or having a compantion do so by observing your gait. Smart!
Would you have known about the "Silent Coach" if you and your girls had not been skaters?
