The postero-anterior-anterior-posterior (PA AP) muscle chain

Composition of the postero-anterior-anterior-posterior (PA AP) muscle chain:

The postero-anterior-anterior-posterior (PA AP) muscle chain

Chaine musculaire AP

The main chain has 4 muscle groups, each with a specific function:

  • The Sentinel Group of the Vertical Axis:
    • Deep posterior muscles of the spine:
      • Multifids.
      • Inter apophyseals.
      • Interspinous.
      • Neck rotators, thoracic multifidus.
    • Anterior deep muscles of the spine :
  • The group of respiratory and pressor muscles are involved in respiratory function and influence circulation by modifying venous return:
      • Overcostals.
      • External intercostals.
      • Diaphragm.
      • Transverse of the abdomen.
      • Middle intercostals(PA AP, AL, AM)
      • Internal intercostals (PA AP, AL)
  • The group of muscles adjusting and regulating the centers of gravity :
  • The group of relay muscles connects the group of respiratory muscles PA AP to the horizontal dynamic muscle chains. They also play the role of accessory respiratory muscles:
    • The muscles of forced inspiration and stabilizers of the scapula which are also part of the PL chain:
    • The muscles of inspiration:
    • The muscles of forced expiration which are also part of the AL chain :
      • Small posterior and inferior serratus.
      • Internal intercostals
  • The muscles connecting the main muscle chain to the secondary chains of the horizontal axis :
      • Iliac, towards the lower limb.
      • Small pectoral, towards the upper limb.
