Draft — clinical review required

In single-limb stance the pelvis drops on the side of the swinging leg.

Observe
  • Opposite iliac crest drops during stance (rear view).
Example mechanisms
  • Reduced hip abductor capacity on the stance side.
  • Structural hip changes.
  • An observed deviation describes movement; it does not identify a single diagnosis or a single weak muscle.
Possible compensation
  • A lateral trunk lean toward the supporting leg can keep the pelvis level (see its own lesson).
What to examine next
  • Hip abductor strength and endurance.
  • Single-leg stance observation.
  • Hip range of motion.
Clinical reasoning sequence
  • Observe → Explain possible causes → Examine → Choose an intervention → Reassess.

Draft — clinical review required

Starting points for verification. Validated protocols are linked where available; clinical content has not yet been reviewed.

Learning objectives
  • Recognize contralateral pelvic drop and when it occurs in the gait cycle.
  • Separate the observed movement from a possible cause and from any compensation.
  • Choose examination findings that would help distinguish between causes.
