hip flexion, abduction, and ER with knee flexion
for grades 3 and up, how is the pt positioned when testing the sartorius with MMT?

for grades 0,1,2 how should the pt be positioned when testing the sartorius with MMT?
same test as grades 3 and up only place the pt in supine

where should the PT stabiilze during sartorius MMT?
no stabilization, both hands used for resistance
where should resistance be applied when testing the sartorius with MMT?
- one hand at ankle to move pt’s foot laterally and straighten the knee
- other hand at knee to move the hip into extension and adduction
