A TV show host has labor contractions simulated using electrodes to see how he can handle the pain of labor. This is really fun to watch! It's also fun to see how they have him try distraction techniques (self-hypnosis), positioning, sitting on the birth ball, and even taking in "gas and air" (laughing gas for those in the US). It's worth watching!
As a side note, I can't imagine how well non-pharmacological pain relief methods would work on simulated labor. Unfortunately for the man in this video he didn't get to experience any hormonal interplay or rise in oxytocin which provides a natural buffer and feelings of well-being. It just isn't the same as real labor.
