That can’t happen. First, The transverse abdominis is located anterior and originates from the lateral third of the inguinal ligament, from the anterior three-fourths of the inner lip of the iliac crest, from the inner surfaces of the cartilages of the lower six ribs, interdigitating with the diaphragm, and from the lumbodorsal fascia.
It inserts anteriorly in a broad aponeurosis, the lower fibers of which curve inferomedially (medially and downward), and are inserted, together with those of the internal oblique muscle, into the crest of the pubis and pectineal line, forming the inguinal aponeurotic falx, also called the conjoint tendon. In layperson’s terminology, the muscle ends in the middle line of a person’s abdomen.
While the Multifidi muscle consists of a number of fleshy and tendinous fasciculi, which fill up the groove on either side of the spinous processes of the vertebrae, from the sacrum to the axis. The multifidus is a very thin muscle.
Second, To correctly engage the TvA the client or patient must be supine with knees bent or hooklying and draw the navel up towards the chest which concentrically contracts the TvA.
To contract the multifidi properly, the client or patient has to be prone, be educated to “turn on” and isolate the multifidi first before engaging the glutes or hamstrings with the opposite leg exercise. This is done by palpating along lateral to the S.P. just above the Transverse process(TP) and asking and cuing the client to first contract the multifidi then the glutes and hamstrings. This is correct order and technique! This is also based on the literature and research….
