A couple of years ago I worked with my Occupational Therapist and a machine for my hand and finger function. She stuck electrodes on my hand and arm, set the device on and buzzzzzzz! it tried to get my brain and nerves to notice the electricity. Not too comfortable, but I had good results. However, it was a pain to set up.
This week my OT took out a new version, where everything is computerized and WiFied. It took two minutes to set up and buzzzzzzz! off we went. It still is not very comfortable, but at least it is easy to set up.
I will report any results. Anyone else have interesting devices?
