Sweet! I've posted a study on that in case anyone doubts what svespie is saying.

Another factor to consider is that it seems that most of the "damage" or microtrauma that may be one trigger of hypertrophy (along with substrate accululation, perhaps) happens on the negative portion of a LIFT. This is obviously a very specific type of damage like you are implying...in fact it is what is "supposed" to happen. Like you say, there may be damage done by electrical stimulation but a pulled muscle is damage too..um, enough said.
Nice post.
