Seems that it could be done with a handful of off-the-shelf parts. From
browsing the group, I've seen where these are often class projects.
Purpose - Determine specific muscle maximum output.
Input- Standard skin electrodes.
Output - LEDs preferred over sound.
Requirement - no programmable chips.
Application - I severed the median and ulnar nerves (and a bunch of other
stuff) just above the elbow. After a couple surgeries, I've gained some
motion in my thumb, and I'm trying to exerecise it to the max muscle
activity level.
I've used a commercial unit in the Occupational Therapy clinic, but it has
a fancy LCD display with mmv readings, timers, etc. that I don't need.
I visualize an output of a simple string of LEDs. If I remember
correctly, the commercial unit displayed readings of 10 to 60 mmv,
depending on pad placement and fatigue level. With luck, this will
increase, but I don't know what normal limits are, and don't expect to get
anywhere near normal levels. Changing ranges would be a nifty.
Seems it could be done with a power supply, amplifier, and LED driver
chip, or maybe easier. I've got a well stocked junk box.
Any suggestions?
