PDS

Pelvic Displacement Syndrome (PDS) is a very common but relatively unknown syndrome in which one side of the pelvis is displaced from the other side of the pelvis creating a pelvic imbalance with significant leg length discrepancy. Pelvic displacement can also cause a helical pelvic rotation emanating from the pelvis upward in the spine and an opposite downward rotation through the legs resulting in many collateral issues from the bottom of the feet to the sub-occipital muscles.

Physical symptoms associated with PDS

PDS2
  • Pain emanating from the femoral socket

  • Pain in the greater trochanter

  • Pain in the tensor fascia latae

  • Pain in the gluteus maximus

  • Pain in the sacral illiac area

  • Pain in the lower back

  • Pain in the cervical spine

  • Slipped rib syndrome

  • Sciatic pain

  • ITB Band syndrome

  • Piriformis syndrome

  • Unidentified cause of knee or meniscus pain

  • Shoulder injuries or pain localized to one shoulder

  • Localized trapezius pain on one side or another

Visual symptoms associated with PDS

PDS3
  • One shoulder depressed

  • Irregular lunge pattern

  • One piriformis is tighter than the other side

  • Pant seam askew to one side

  • One knee bows out when walking

  • Squat viewed from the rear and side shows a twisting motion

  • One foot turned out more than the other

  • Uneven pronation and supination of the feet

  • Uneven wear pattern on the bottom of shoes

  • Anterior displacement (rotation) of either the left of right side of the pelvis.

Pelvic rotation associated with PDS

PDS1

Pelvic rotation associated with PDS can cause:

  • Uneven pronation and supination of feet as pelvic rotation affects foot angle

  • Knee joint direction changes, typically affecting the outer leg unfavorably

  • Uneven leg muscle development due to force distribution changes

  • Reinforced irregular gait patterns causing further damage
