Foot Drop: Causes, Exercises, Braces and Physiotherapy

Foot drop means that lifting the front of the foot and toes is difficult. The toes may catch on the floor, the knee may lift higher to clear the foot, and walking can feel less safe or more tiring. It is a symptom rather than a diagnosis, so treatment starts by finding the cause.

Physiotherapy can help many people improve walking, maintain movement, strengthen muscles that are able to work and reduce falls risk. A brace, splint or specialist electrical stimulation may also be useful. New or worsening weakness still needs medical assessment before relying on exercises alone.

What is foot drop?

Foot drop, also called dropped foot, is difficulty lifting the foot upwards at the ankle. The medical term for this movement is dorsiflexion. It often affects one side, although some neurological conditions can affect both feet.

Typical signs include:

• the toes scuffing or catching during walking;
• lifting the knee higher than usual to clear the foot;
• the foot slapping down after the heel touches the ground;
• difficulty walking on the heels;
• weakness when lifting the foot or straightening the toes;
• numbness or tingling over the shin or top of the foot in some cases;
• more trips, near-falls or fatigue when walking.

See a GP if you develop difficulty lifting the front of the foot or toes. A clinician needs to work out whether the problem comes from a peripheral nerve, the lower back, the brain or spinal cord, a muscle condition or another cause.

What causes foot drop?

The NHS says the most common cause is injury or compression of the nerve that controls the muscles lifting the foot. This is often the common peroneal nerve near the outside of the knee. Pressure can follow a sports injury, prolonged kneeling or squatting, crossing the legs repeatedly, immobility, or some hip and knee operations.

Other causes include:

• a slipped disc or another lower-back problem affecting a nerve root;
• peripheral neuropathy, including neuropathy associated with diabetes;
• stroke, multiple sclerosis, Parkinson’s disease or spinal cord injury;
• inherited nerve conditions such as Charcot-Marie-Tooth disease;
• muscle or motor-neurone disorders;
• trauma around the knee, lower leg, pelvis or spine.

The pattern matters. Foot drop that appears suddenly is different from weakness that develops slowly after pressure on a nerve. Pain, numbness, back symptoms, other weak muscles and changes in balance help guide the assessment.

How is foot drop assessed?

A GP, neurologist, orthopaedic clinician or physiotherapist may examine how you walk and test ankle, toe, knee and hip strength. They may also check reflexes, sensation, spinal movement and whether the weakness follows the pattern of a particular nerve or nerve root.

Investigations depend on the history and findings. These may include blood tests, nerve-conduction studies, electromyography, or imaging of the lower back, knee or leg. A scan is not automatically needed for every person, but progressive weakness or signs of a serious neurological cause require timely specialist assessment.

NICE advises that clear compression of the common peroneal nerve without signs of a spinal nerve-root problem may be managed with a splint and review. If there is no improvement after six weeks, neurological assessment should be considered. This does not mean every case should simply wait six weeks: sudden, progressive or otherwise concerning weakness follows a more urgent pathway.

Foot-drop treatment options

Treatment depends on why the foot is weak and how long the problem has been present. The plan may combine medical treatment for the cause with rehabilitation and equipment for safer walking.

Physiotherapy

Physiotherapy may maintain ankle movement, strengthen muscles with useful activation, improve balance and retrain walking. It can also address weakness at the hip and knee that makes foot clearance harder. The aim is better function and safety, not simply completing a standard list of ankle exercises.

An ankle-foot orthosis or brace

An ankle-foot orthosis, often shortened to AFO, supports the foot in a better position during walking. A lighter foot-drop brace or shoe insert may suit some people. Proper fitting matters: a device that rubs, changes skin colour, causes numbness or increases pain needs review.

A brace can reduce tripping and make walking more efficient, but it does not necessarily restore nerve function. The correct device depends on muscle tone, ankle range, skin health, footwear, walking pattern and the underlying condition.

Functional electrical stimulation

Functional electrical stimulation, or FES, times a small electrical stimulus to help lift the foot during walking. NHS specialist services use it for selected people with foot drop caused by central nervous-system conditions such as stroke, multiple sclerosis, cerebral palsy or some spinal-cord injuries.

FES is not suitable for everyone and should be assessed and fitted by an appropriate specialist service. A consumer muscle stimulator should not be used as a substitute for diagnosis or specialist fitting.

Medical or surgical treatment

Treating the cause may involve relieving pressure on a nerve, managing diabetes or another neurological condition, or addressing a spinal problem. Persistent severe weakness can occasionally lead to nerve repair, tendon transfer or surgery to stabilise the ankle, depending on specialist assessment.

Foot-drop exercises: a staged approach

Exercises should be selected after the cause and available muscle function have been assessed. If the muscle cannot activate because the nerve signal is absent, repeatedly forcing resistance may not improve it. Rehabilitation can still protect movement, maintain other muscles and improve walking safety.

1. Maintain comfortable ankle movement

Supported ankle movement can help prevent avoidable stiffness. A clinician may suggest gently bringing the foot upwards with assistance from the other foot, a towel or a strap, then returning slowly. Calf stretching may be useful if the ankle is becoming tight, provided there is no fracture, acute injury or other restriction.

Avoid pulling aggressively into pain. Reduced sensation can make it harder to judge pressure, so inspect the skin and seek advice if you have diabetes, poor circulation or numbness.

2. Strengthen movement that is present

If you can lift the foot even slightly, practise controlled dorsiflexion without compensating at the hip. Progress may move from gravity-reduced movement to seated lifting and then light resistance. Toe lifting, outward ankle control and calf work may be added when appropriate.

The quality of movement matters more than a high repetition count. Stop if weakness is rapidly worsening, the exercise causes new numbness or pain, or the foot becomes harder to control afterwards.

3. Retrain walking

Walking practice may focus on heel contact, foot clearance, step length and safe turning. A mirror, video feedback, suitable walking aid or properly fitted AFO can help. The physiotherapist may also train the hip and knee because these joints contribute to clearing the foot.

4. Improve balance and falls confidence

Supported weight shifts, sit-to-stand practice, stepping over low obstacles and balance work near a stable surface can improve everyday control. The difficulty should be challenging without creating an avoidable fall risk.

How long does foot drop take to recover?

There is no single recovery time. The NHS notes that foot drop can improve on its own or with treatment, but it can sometimes be permanent. Recovery depends on the location and severity of nerve damage, how quickly the cause is treated, general health and whether the weakness comes from a continuing neurological condition.

Some compression neuropathies begin to improve over weeks, while nerve recovery after a more substantial injury can take many months. Conditions such as stroke or multiple sclerosis may need longer-term rehabilitation and equipment. Early gains may appear as fewer trips, a smoother step or a small return of ankle movement rather than full strength.

Progress should be reviewed if weakness is worsening, no change is seen within the expected clinical window, or the current brace or exercise programme is not improving safety. Recovery claims based on a fixed number of sessions are not reliable.

Reducing falls risk at home

The NHS advises practical changes because foot drop increases the risk of tripping:

• wear secure, well-fitting shoes;
• use the prescribed brace or walking aid;
• remove loose rugs, cables and clutter from walking routes;
• keep stairs and hallways well lit;
• use handrails and take extra care on uneven ground;
• avoid walking in socks on slippery floors.

Fatigue can make foot clearance worse. Plan breaks on longer walks and use equipment before repeated near-falls undermine confidence.

How physiotherapy can help

A physiotherapist can assess strength, ankle range, balance, gait and falls risk, then coordinate rehabilitation with the medical diagnosis. Treatment may include exercises, gait retraining, advice about footwear and walking aids, and referral to orthotics or specialist services.

Online physiotherapy may help review visible movement, home safety and exercise technique when the diagnosis and medical plan are clear. It cannot test reflexes or sensation fully, fit an orthosis, perform nerve studies or replace urgent neurological assessment.

If foot drop is accompanied by back and leg pain, read our guide to slipped disc symptoms and recovery. If it developed after a stroke, our stroke rehabilitation at home guide covers strength, balance and fatigue in more detail.

Foot-drop red flags: when to get urgent help

Call 999 for weakness that begins suddenly, especially with facial drooping, arm weakness, speech difficulty, loss of coordination, severe headache or numbness on one side. Sudden restricted weakness can still be a stroke or transient ischaemic attack.

Go to A&E immediately if foot drop occurs with severe lower-back pain and new difficulty starting or controlling urine, loss of bowel control, numbness around the genitals or bottom, or rapidly worsening weakness in both legs. These can be signs of cauda equina syndrome.

Urgent assessment is also needed for weakness after a head, neck or back injury; rapidly progressive weakness over hours or days; breathlessness at rest; difficulty swallowing; or a cold, pale, blue or severely painful foot. Seek prompt medical advice if the weakness is steadily worsening or spreading to other muscles.

Frequently asked questions

Can foot drop be fixed with exercises alone?

Sometimes strength and walking improve with rehabilitation, but exercises do not treat every cause. A compressed nerve, spinal problem, stroke or progressive neurological condition may require medical treatment, a brace, FES or specialist care. Assessment should come first.

Should I walk without a brace to make the muscles work?

Not if this causes repeated toe-catching or falls. A brace can make walking safer and more efficient while rehabilitation continues. Any change in brace use should follow advice from the clinician or orthotist who assessed you.

Can foot drop become permanent?

Yes, although many people improve. The outlook depends on the cause and severity. Early investigation is particularly important when weakness is new, progressive or accompanied by other neurological symptoms.
