Pictures of the line

Consists of the following muscles and connective tissues

Function of line

  • Helps maintain balance across all planes
  • In imbalance, the SPL participates in creating, compensating for and maintaining twists, rotations, and lateral shifts in the body
  • Dysfunction in SPL will easily affect function in other lines such as SBL, SFL, LL, and deep back arm line due to sharing muscles with those lines
  • The overall function is to create and mediate spirals and rotations in the body, and to steady the trunk and leg to keep it from folding into rotational collapse
