  2. PCAS relative psoas cross-sectional area in supine
  3. PCAHF relative psoas cross-sectional area in right lateral decubitus with hip flexion
  4. PCAHN relative psoas cross-sectional area in right lateral decubitus with hip in neutral
  5. There were statistical differences between PCAHN compared to the PCAS and PCAHF at all levels (p < 0.05).
