From the platform presentations of the APA combined sections meeting:
"Which exercises target the gluteal muscles while limiting activation of the TFL? EMG assessment using fine wire electrodes".
The authors point out is important to limit the action of the TFL in PF rehab because it "internally rotates the hip & exerts a lateral force on the patella". I'm not sure the TFL actually does this once the foot is on the ground, but let's assume it does for the sake of argument.
The authors immediately go horizontal/floor to the CLAM exercise, as it gives the best EMG results.
Well, you know how I feel about lying on the floor. What are some ways we could quiet the TFL during glut. strengthening in an upright functional position?
