Laboratory / Research Equip

Has anyone used a lab / reasearch type device such as is available from Grass Instruments or similar? I own an SD9 and have been able to get some very interesting sensations with it. You do have to have a good understanding of electrical parameters to use it properly, with the wrong settings it can produce some nasty sensations. Though generaly safe. It is mains powered and it's output is isolated for safety. It is designed for human use. It is used for reasearch to stimulate nerves and muscles.

I am an electronics engineer BTW.

I have a lab grade FES box ,intialy when I started having paralysis my doctor thought we will still work out even if you don't feel it, it was remarkably short order we found what a huge mistake that was , it does everything from TENS to Russian and everything you can think of with wall power and 8 outputs so you can pretty much isolate an arm or leg or group of muscles and control them electricly , I remember strapping my arm down with a weight attached to my hand and doing reps of 10 contracting my muscles and relaxing my muscles using a knob and button and electrodes dotting my arm big ones that you wash and reuse attaching it with conductive jell and velcro straps.its been sitting in a case in the closet for years .
