DOMestic Bdsm and Female Domination

Last summer, she was hit from behind in a car accident that
resulted in neck and back injuries, so we haven't played in a
very long time. Recently, she had neck fusion surgery where
because of chronic pain resulting from the accident injury the
surgeon had to go in and remove a disc in her neck and mount a
titanium plate with four screws to hold the two adjacent
vertebrae together so that they would fuse and take the pressure
off the nerves that were being pinched and causing the constant
pain and loss of sensation in her extremities. This now seems to
be providing her with some relief, although the trade-off is of
course some loss of mobility in her neck.

My questions are these:-

Does any dominant here engage in electrical play with a
submissive who has an internal metal plate of some sort? If so,
other than the obvious of avoiding close proximity to it with a
source of static electricity, what are the implications of
having something like this in their body? Does it change or
amplify what they're feeling at any other location?

We would appreciate getting any first hand information or data
that someone here might be in a position to supply on this
subject and doesn't mind sharing it with others. By first hand
information, I mean we are interested in hearing input on
sensations from the sub's perspective (as opposed to the Dom's
perspective) although it may be the Dom who is relaying the
information.

Sincerely,
Master Robert
