Anatomy

  • Sacrum to body of C2
  • Continuous w tectoral membrane

Function

  • Prevents disk protrusions and restrains flexion of vert column
  • Dural mater strongly adhered to PLL at C3 and higher, diminishes lower

Manual therapy

  • IASTM between
  • Cupping
  • Fascial pumping (to Lumbar spine and sacrum)1
    • place one hand on T/S kyphosis with fingers pointing rostrally
    • Place the other hand on the sacrum with fingers pointing caudally
    • As the patient inhales, assist the spine into flexion and distraction
    • As the patient exhales, hold the position, then slowly decrease the flexion and distraction force
