Foot drop · ground contact
Observed deviation · reduced dorsiflexion and toe clearance

During swing, ankle dorsiflexion helps lift the forefoot so the toes can clear the ground.

Illustrative demonstration angles · same walking clock for both figures.

The foot stays more plantarflexed as the leg swings forward, so the toes pass closer to the ground.

Observe
  • In typical walking the forefoot lifts during swing.
  • With foot drop the toes stay closer to the ground and may catch or drag.
Example mechanisms
  • Weakness of the ankle dorsiflexors.
  • Restricted ankle movement.
  • Other contributors to reduced clearance: reduced knee flexion in early swing, reduced hip flexion in swing, limb-length difference.
  • An observed deviation describes movement; it does not identify a single diagnosis or a single weak muscle.
Possible compensation
  • Increased hip and knee flexion lifts the whole limb (excessive hip flexion during swing).
  • Other strategies — hip hiking, circumduction, vaulting on the opposite leg — each change a different part of the walking pattern.
What to examine next
  • Ankle and knee range of motion.
  • Strength and motor control of dorsiflexors and hip flexors.
  • Tone and velocity-dependent resistance.
  • Limb length; footwear.
Clinical reasoning sequence
  • Observe → Explain possible causes → Examine → Choose an intervention → Reassess.

Sources and review status

Draft — clinical review required

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

Learning objectives
  • Recognize foot drop during swing 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.
