Two POEs are used--NRCH (Loring AFB, Maine) and PTFL (McGuire AFB, NJ).
Continuing with the example of Tables 9 through 12, POE NRCH is close enough to PTFL and to several other POEs for RLNs to move to a different triplet using any of these POEs.

prevents external rotation in dorsiflexion and resists ankle dorsiflexion along with the medial ligaments, which are primarily responsible for these constraints.
