I have bilateral devices inserted in Jan and March 1996. I have gotten much help from them, and they really do help keep me moving. I normally turn them off at bed-time to both save on batteries and to give my brain a little rest, I usually turn them on again when I use my bedside commode. This often makes the difference in whether I can make it on and off without calling for help.=20 --=20 q=A8 I still have quite a challenge living with Parkinsons, but this has been very helpful in allowing me to move, and so in my opinion, it does help control bradykinesia.
