Muscles Involved:[edit | edit source]

Patient Positioning[edit | edit source]

  • Grades 3 to 5 - Patient is in prone
    • to test gluteus maximus and hamstrings - side-side knee in extension
    • to test gluteus maximus only - test-side knee flexed to 90°
  • Grades 0-2 - Patient is in side lying ('gravity minimal' position)

Therapist Position[edit | edit source]

  • Therapist to stand on test side, stabilize the pelvis over the sacrum and palpate muscular recruitment

To Test[edit | edit source]

  • Patient actively extends the hip
  • For grades 4 to 5 apply resistance through distal thigh in the direction opposite to hip extension.[1]
  • To satisfy grade 5 'normal muscle' performance criteria, the patient must have the ability to move through complete range of motion (active resistance testing) OR maintain an end point range (break testing) against maximum resistance.
