Dr. Vickery,
I think that I would check to see that the threshold and intensity controls
are adjusted for their maximal performance, and if that does not improve
things, I would then begin to wonder if your aray has become worn out in
which case you might need to consider having work done on it. Those
vibrating pins can become worn in time which might account for the
difference in what is felt in using the device.
