Accelerate, Decelerate + Change Direction
What is the function of the POS
Works with AOS for rotation + pulling heavy objects
Active when walking (compress SI joint)
What is the function of the LS
Important for balance + side bending
Generates force to swing leg
Stabilize pelvis while walking + stairs
