I've explained this once before but Ill have another crack for CW and Matt's benefit.
Abduction = Movement of a limb away from the body
Adduction - Opposite of abduction
Leg Abduction - The movement of the leg away from body to the side.
Muscles used - Glute Medius, Glute Min, Glute max and TFL
Led Adduction - Bringing the leg back in toward the body
Muscles used - Adductor Magnus, Addcutor Brevis and Adductor Longus)
CW, the muscles around your lower stomach have absolutely nothing to do with ABDUCTION.
I would be sacking my physio if I were you.
