@Sue Hi Sue. Have a look at a photo of the brace. They come in different lengths, so engaging the quadriceps gives an idea of how high on the thigh it should go.

@Liz I don't quite see how engaging the quadriceps fits into the text.

Michael Barnett Oct 1, 2020:

@Liz Good job Liz. Enter it as an answer and you will get my "agree".

Suzie Withers Oct 1, 2020:

Liz's links look convincing to me

Sue Davis Oct 1, 2020:

perhaps until "locking in extension by quadriceps" is effective. This rather negates my earlier suggestion.

Begin by tightening (squeezing) the anal muscle for 20-30 seconds. •. Do not squeeze abruptly but gradually tighten up the muscles over a period of 5 seconds. •.

different usage:
e verrouillage périnéal consiste à serrer les muscles du plancher pelvien avant, pendant et 2 à 3 secondes suivant tout effort physique qui augmente la pression sur celui-ci, comme la toux, l'éternuement ou le geste de prendre un enfant dans ses bras.

Could it be "engaging the quadriceps"??

@Sue That is a great idea. What do you make of "jusqu'au"? It looked to me like it was indicating how high the brace was to fit, but, of course there is no anatomical position called a "quadriceps lock".

Suzie Withers Oct 1, 2020:

@Sue Yes, I've seen braces that have locking mechanisms at the thigh level, so perhaps it's something to do with that?

Sue Davis Oct 1, 2020:

This may refer to a brace that allows movement at the knee joint but locks it in extension during e.g. heel strike. See https://basko.com/pdf/8900900.pdf

During gait, the device locks just prior to heel strike for support during
stance and unlocks the knee at heel off in preparation for swing. This action is intended to mimic the normal physiologic action of the knee extensors. (i.e. quadriceps)
