Understanding the condition

Foot drop means difficulty lifting the front of the foot. A problem with the common peroneal nerve is one possible cause, but the sciatic nerve, nerve roots and other neurological conditions may also be involved.

What might you notice?

  • Catching the toes when walking or difficulty clearing the foot.
  • Weakness affecting ankle or toe movement.
  • Numbness, tingling or nerve pain in the leg or foot.

These symptoms can have more than one cause. A clinical assessment is needed to establish the diagnosis.

Specialist assessment

The consultation includes examination of strength, sensation and gait. The history of an injury, operation or compression is reviewed. Nerve tests and imaging may help locate the problem and assess its severity.

Your treatment options

Treatment may include therapy, an ankle-foot orthosis and measures to reduce falls. Selected nerve injuries may benefit from decompression or reconstruction. Where nerve recovery is limited, tendon transfer may be discussed.

When to seek helpNew or rapidly worsening foot drop needs prompt medical assessment. Sudden weakness with other neurological symptoms should be treated as an emergency.

Common questions

Does foot drop always come from the knee?

No. The problem can arise at different levels, including the spine, sciatic nerve or common peroneal nerve. Establishing the cause is essential.

Is a brace helpful?

An ankle-foot orthosis can help support walking in some patients. The most suitable support is decided with the clinical and therapy team.
