Yes, confirming that the electrodes should never touch the metal rod since it’s exposed. It’s ok if the stump moves or bounces as long as she is still comfortable. That’s because the active electrical field is capturing motor neurons which results in some muscle fasciculation. IF she does not tolerate the movement of the stump, then she should turn the intensity down 5 percentage points to 40% - that should be enough to reduce or eliminate the muscle fasciculation. If it’s not she can take it down another couple percent. No need to go all the way down to 30%. Then she can gradually raise the intensity as her body adapts to the field which might be 2% to 5% every 5 minutes.
Use B-set electrodes.
Electrode placements for phantom limb pain may take a few iterations to find a placement scenario that captures the nerves which are transmitting signals to the brain that there is pain in a portion of the limb that no longer exists.
Phantom limb pain pad placements might be on the medial and lateral sides of the stump, anterior and posterior, end of the stump or any combination thereof. The key is to capture the correct nerves that are conducting the pain signals to the brain.
It takes a little trial and error to find the right pad placements versus something conventional like bilateral lumbar pain. But it can be very much worth the time because I’ve seen BioWave help numerous times.
