Tens Units during retention

For those wanting to enhance the cramping element, I wonder about using a tens unit with pads taped to the abdomen during enema retention. The giver could control the level of energy, which could increase abdominal muscle contractions. I haven't tried it, but I wonder if it would make the retention aspect more challenging.

I love enemas and distention, but have no experience with TENS or other e-stim products, though there are some Zity members who write about enemas who also do e-stim. You might also post this question on an e-stim thread here.
