A 34-year-old male presents to the office with the complaint of lower back pain. History reveals that he recently began training for his first 5K race. The pain has been present for approximately two weeks, is described as occasional, position-dependent, sharp pain in the right lower back without radiation down either leg. Physical examination reveals a negative straight leg raise test, full strength, sensation, and 2/4 reflexes. Osteopathic examination reveals a standing flexion test is positive on the right, a superior ASIS on the left and a superior PSIS on the right. The dysfunctional sacral axis in this patient's somatic dysfunction is the

A. inferior transverse axis
B. left oblique axis
C. middle transverse axis
D. right oblique axis
E. superior transverse axis

The correct answer is: A

inferior transverse axis

The biomechanics of the iliosacral complex can be quite complicated. Osteopathic texts describe five primary axes around which the iliosacral complex may move. These five axes are: the superior transverse axis, the middle transverse axis, the inferior transverse axis, and the right and left oblique axes. Innominate rotation occurs around the inferior transverse axis during the walking cycle, and this is also the axis around which innominates may become dysfunctional.

The primary muscle group used in the muscle energy treatment of this somatic dysfunction is the?

  1. abductors
  2. adductors
  3. hamstrings
  4. piriformis
  5. quadriceps
