Q

Describe the specific Kinesiology occuring during the relevant screening test for a weak glute med

A

The tests for weak glute med include APR and Trendelenburg. trendelenburg is posative if the opposite hip drops, when the hip drops it causing the acetabulum to roll and glide inferior lateral. Durring APR testing for medial hip rotation the medial rotators are ethe force, lateral rotators are the resistance and control
Horizontal plane/y axis
femur moves medial (osteo kin) and the head of the femur rolls ant. and glides posterior (arthro kin)

Q

GAIT(-A-MUNDO) lumbar

A
  • As the right leg swings forward the contraction in the RF pulls the right innominate into
    anterior tilt
  • Contraction of the right psoas creates an increase in the lordotic curve on the right and a
    corresponding left rotation of the lumbar
  • The left leg is planted. The left piriformis is contracting, stabilizing the right oblique axis
    of the SI joint. The superior end of the axis is stabilized by the right innominate. The
    right axis is “locked” motion will occur around this axis.
  • As the lumbar levers the sacrum, rotation of the lumbar to the left will force the sacrum
    into right rotation.
  • Thus the sacrum is torsioned to the right on the fixed right oblique axis.
  • NOTE-contraction of the right multifidii cause the sacrum to rotate to the right. The
    orientation of attachment of these muscles to the lumbar vertebrae will cause rotation of
    the lumbar to the left, following the laws of vertebral mechanics.
