In a reflex loop, signals short circuit back to the muscles to tell them to go into a massive contraction to protect themselves under load and then this loop just keeps cycling on itself.....resulting in muscle spasm.

Hmm...very interesting. Mrs. Fumes is a grad student and has been spending an inordinate amount of time sitting on a very worn out couch with her laptop and several large stacks of papers. I suggested that she get up and stretch occasionally, but oh no, there's too much work to do and no time. I would expect that sitting in an ergonomically inappropriate position for extended periods of time might be a trigger for back spasms.
This was quite enlightening! Thanks for taking the time, John.
