Hi Yaro, I am not sure i understand the question...

Hi GC, you mention that TA and multifidus (LM) are not initiators of posterior pelvic tilt.... it really depends on what your definition of intitiation is.

TA and LM WILL activate BEFORE the RA and Hams actually generate the torques to posteriorly rotate the pelvis. TA and LM won't actually move the pelvis but they are shown to activate BEFORE *movement* intitiation.

If you think of inititation as 1.thought/intention, 2. preparatory movements 3. actual movement, then TA and LM are part of the initiation sequence of movement...
