Question

what is the arthrokinematics of closed chain posterior pelvic tilt?
a) posterior roll, posterior glide
b) anterior roll, posterior glide
c) anterior roll, anterior glide
d) posterior roll, anterior glide

Explanation:

In closed - chain posterior pelvic tilt, the femoral head (in relation to the acetabulum) has a posterior roll. According to the concave - convex rule, when the moving part (femoral head in this case, as the pelvis is tilting and the femur is relatively fixed in closed - chain) is convex (femoral head is convex), the glide is in the opposite direction of the roll. So, for a posterior roll of the femoral head (convex), the glide is anterior.

Answer:

d) Posterior roll, Anterior glide
