Glute Max
During the Stance Phase of Gait, what are the osteokinematics?
the ASIS moves posterior/ superior
If your client presents with compensatory Hip Lateral Rotation during the standing active hip flexion assessment, what my be the cause?
Tightness of the Glute Max
What are the osteokinematics occurring at the hip from toe off to midswing?
femur moves anterior/ inferior
What muscle is responsible for stabilizing sacral torsioning on the appropriate oblique axis?
Piriformis
What is occurring on the left side when the right leg is moving from Mid Swing to Foot Plant?
Mid Stance to Toe Off
_________ is the force for which of the Open Chain Hip Extension from 90 degrees hip flexion
gravity
Which sacral flexion or extension is occurring during the seated flexion test?
Sacral Flexion
The right Piriformis is stabilizing the oblique axis of the SI joints during which phase of gait?
right stance phase of Gait
The force creating closed chain hip extension during a squat exercise is:
CC of Glute Max
During the straight leg test, what are the mechanics occurring to create a positive outcome?
the pelvis is tilting posterior, causing the sacrum to extend and the lumbar to flex
while observing your client’s Gait, you notice a restriction in left torso rotation. What may be the cause?
tight left psoas major
When the resistance to a motion is Gravity, you can increase that resistance by adding___________.
mass
Which direction is the nucleus of the intervertebral disc forced during lumbar flexion?
Posterior

What represents the control for open chain medial hip rotation?
EC of Glute Max
Why are roll and glide occurring in opposite directions during Open Chain Hip Abduction and Adduction?
