analgesia

Yet for 40 years they did open-heart surgery in newborn babies without analgesia.

To be fair, there are vets who will insist on using post-surgery analgesia for procedures like dehorning, castration, and so forth.

While exercise-induced analgesia is a pretty robust effect, it doesn’t seem to work as well in chronic pain patients.

If exercise-induced analgesia is working, you’d expect the subjects to tolerate more pressure after the squat compared to their baseline test.
