Can Diabetes Cause Foot Drop?

Yes. Diabetes can cause or contribute to foot drop by damaging the nerves responsible for sensation and muscle movement in the feet and legs.

Foot drop occurs when it becomes difficult to lift:

• The front of the foot
• The ankle
• The toes

When walking, this may cause:

• The toes to drag
• The front of the shoe to catch
• Foot slap
• A high-stepping gait
• The leg to swing outwards
• An increased risk of trips and falls

The NHS specifically lists peripheral neuropathy caused by diabetes as one of the recognised causes of foot drop.

However, having diabetes does not mean that every episode of foot drop is caused by diabetic neuropathy.

Someone with diabetes can also develop foot drop because of:

• A trapped common peroneal nerve
• A slipped disc
• Spinal stenosis
• Stroke
• Multiple sclerosis
• Surgery
• Trauma
• A hereditary neuropathy
• Muscle disease

New foot drop should therefore be investigated rather than assumed to be an expected complication of diabetes.

What Is Diabetic Neuropathy?

Diabetic neuropathy is nerve damage caused by diabetes.

Over time, raised blood-glucose levels can damage the small blood vessels that supply nerves. When nerves do not receive an adequate supply of oxygen and nutrients, their fibres can become damaged and may stop carrying messages normally.

Nerves are responsible for carrying signals that allow you to:

• Feel touch
• Feel pain
• Detect temperature
• Know where your joints are positioned
• Move muscles
• Maintain balance
• Control internal organs

Diabetic neuropathy can therefore affect:

• Sensation
• Muscle strength
• Coordination
• Reflexes
• Balance
• Internal body functions

The precise symptoms depend on which nerves are affected.

How Does Diabetic Neuropathy Cause Foot Drop?

The muscles that lift the front of the foot rely on motor nerves to carry instructions from the brain and spinal cord.

If these nerves become damaged, the muscles may receive:

• Weaker signals
• Delayed signals
• No useful signal

This can result in:

• Weak ankle dorsiflexion
• Weak toe lifting
• Poor control when lowering the foot
• Foot slap
• Toe dragging

Peripheral neuropathy can involve sensory nerves, motor nerves or both. Diabetes UK confirms that diabetic peripheral neuropathy may affect movement as well as sensation and that symptoms can include weakness and loss of reflexes.

Does Diabetic Neuropathy Usually Cause Numbness Before Foot Drop?

Often, sensory symptoms are noticed before major muscle weakness.

Early or common symptoms can include:

• Tingling
• Pins and needles
• Burning
• Shooting pain
• Numbness
• Reduced temperature sensation
• Reduced awareness of foot position

As neuropathy progresses, someone may also experience:

• Muscle weakness
• Reduced reflexes
• Balance problems
• Changes in foot shape
• Difficulty walking

NHS guidance includes weakness, particularly in the feet, among the symptoms of peripheral neuropathy.

Foot drop is therefore possible, but it is not the only or most common symptom of diabetic neuropathy.

Can Diabetes Damage Motor Nerves?

Yes.

Motor nerves control muscle movement.

Diabetes UK identifies diabetic motor neuropathy as one form of diabetic nerve damage and confirms that peripheral neuropathy may involve motor nerves, sensory nerves or both.

Motor nerve damage may cause:

• Weakness
• Muscle wasting
• Reduced reflexes
• Poor ankle control
• Difficulty standing
• Changes in walking

When the dorsiflexor muscles are affected, foot drop may develop.

Can Diabetes Damage Only One Nerve?

Yes.

Diabetes more commonly causes a widespread peripheral neuropathy, but it can also cause a focal neuropathy, where one individual nerve is affected.

People with diabetes are more susceptible to nerve-entrapment syndromes, where a nerve becomes compressed as it passes through a narrow anatomical area. The common peroneal, or fibular, nerve can be affected near the outside of the knee.

Peroneal nerve involvement may cause:

• Pain outside the lower leg
• Weakness lifting the big toe
• Weakness lifting the foot
• Reduced outward foot movement
• Numbness over the top of the foot
• Foot drop

This means diabetes can contribute to foot drop through both:

• Widespread diabetic polyneuropathy
• More localised nerve compression

Why Are People With Diabetes More Vulnerable to Trapped Nerves?

Diabetes can damage nerve fibres and the small blood vessels that nourish them.

A nerve that is already less healthy may be more vulnerable when exposed to:

• Pressure
• Stretching
• Prolonged positioning
• Tight supports
• Swelling
• Repetitive movement

NIDDK guidance confirms that people with diabetes are more likely to develop nerve-entrapment syndromes than people without diabetes.

This does not mean that every diabetic foot drop originates near the knee.

A clinician still needs to determine whether the problem is located in the:

• Peripheral nerves
• Common peroneal nerve
• Sciatic nerve
• Spinal nerve root
• Brain
• Spinal cord
• Muscle

Can Diabetes Cause a Trapped Peroneal Nerve?

It can increase susceptibility to peroneal nerve entrapment.

The common peroneal nerve passes close to the surface around the head of the fibula, near the outside of the knee.

It can be compressed through:

• Prolonged leg crossing
• Kneeling
• Squatting
• Bed rest
• Rapid weight loss
• Tight casts or braces
• Surgery
• Direct injury

A person with diabetes may have both:

• Generalised diabetic neuropathy
• A separate local peroneal nerve entrapment

These conditions can occur together.

Read our guide: Can a Trapped Peroneal Nerve Cause Foot Drop?

Can Diabetic Neuropathy Affect Both Feet?

Yes.

Diabetic peripheral neuropathy commonly affects the feet and may develop in a broadly symmetrical pattern.

Someone may notice symptoms in both feet, such as:

• Numbness
• Tingling
• Burning
• Reduced awareness of temperature
• Balance difficulty
• Weakness

Foot drop affecting both sides may occur if motor nerve damage becomes sufficiently significant.

However, bilateral foot drop can also result from:

• Spinal disease
• Hereditary neuropathy
• Neuromuscular conditions
• Other widespread peripheral neuropathies
• Certain neurological conditions

Both feet being affected requires medical assessment rather than assuming diabetes is the only cause.

Can Diabetes Cause Foot Drop on One Side?

Yes, particularly where:

• One nerve is compressed
• A focal neuropathy is present
• The neuropathy is uneven
• There is a separate injury or spinal condition

However, sudden one-sided foot drop must not automatically be attributed to diabetes.

Other possible causes include:

• Common peroneal nerve injury
• Lumbar-disc compression
• Stroke
• Sciatic nerve damage
• Surgery
• Trauma

The onset, pain pattern, sensory changes and other neurological symptoms help determine the cause.

Can Foot Drop Be the First Sign of Diabetes?

It is possible for nerve symptoms to lead to the discovery of previously undiagnosed diabetes, but isolated foot drop is not a reliable way to diagnose it.

A person may first seek medical advice because of:

• Numb feet
• Burning pain
• Tingling
• Balance problems
• Muscle weakness
• Foot drop

Blood tests may then identify raised blood glucose.

However, these symptoms have many potential causes.

Do not assume you have diabetes because you have developed foot drop, and do not assume existing diabetes explains new weakness without further assessment.

Can Prediabetes Cause Nerve Symptoms?

Nerve symptoms can have many causes, and abnormalities in glucose metabolism may be considered during an investigation.

However, foot drop is a significant motor symptom and should not be self-diagnosed as being due to prediabetes.

Assessment may include checking for:

• Diabetes
• Vitamin deficiencies
• Thyroid problems
• Kidney disease
• Alcohol-related nerve damage
• Medication effects
• Autoimmune conditions
• Hereditary neuropathies
• Nerve compression

The NHS confirms that peripheral neuropathy has many possible causes in addition to diabetes.

What Is Diabetic Polyneuropathy?

Diabetic polyneuropathy refers to diabetic nerve damage involving multiple peripheral nerves.

It commonly affects the longest nerves first, which is why symptoms often begin in the:

• Toes
• Feet
• Lower legs

Symptoms may gradually move upwards as the condition progresses.

Possible effects include:

• Reduced sensation
• Burning or shooting pain
• Poor awareness of joint position
• Balance difficulties
• Muscle weakness
• Reduced reflexes
• Foot deformity
• Increased risk of skin damage

Diabetes is the most common cause of peripheral neuropathy in the UK.

What Is Diabetic Motor Neuropathy?

Diabetic motor neuropathy involves damage to nerves that control muscles.

Possible signs include:

• Weakness
• Muscle wasting
• Reduced reflexes
• Difficulty lifting the foot
• Difficulty rising from a chair
• Altered walking

Motor and sensory neuropathy can occur together.

This is important because someone may have:

• Weakness that creates foot drop
• Numbness that prevents them feeling an AFO rubbing

The brace must therefore address mobility without creating avoidable skin pressure.

What Is Diabetic Proximal Neuropathy?

Diabetic proximal neuropathy is a rarer form of nerve damage affecting the:

• Hip
• Buttock
• Thigh
• Upper leg

It is also sometimes called diabetic lumbosacral radiculoplexus neuropathy or diabetic amyotrophy.

Typical symptoms may include:

• Sudden or severe hip, thigh or buttock pain
• Weakness in the leg
• Difficulty standing from sitting
• Loss of knee reflexes
• Muscle wasting
• Weight loss

It usually begins on one side and may later affect the other.

Proximal neuropathy is not the same as straightforward distal foot drop, but wider leg weakness may alter walking and can coexist with lower-leg involvement.

Is Diabetic Amyotrophy the Same as Foot Drop?

No.

Diabetic amyotrophy mainly affects the hip, buttock and thigh and commonly causes:

• Pain
• Proximal weakness
• Difficulty standing
• Muscle wasting

Foot drop specifically refers to difficulty lifting the ankle and toes.

Someone with diabetic amyotrophy can have a complex walking problem and may later show weakness elsewhere, but isolated foot drop should not automatically be labelled diabetic amyotrophy.

Diagnosis may involve neurological examination, nerve-conduction studies and electromyography.

Can Diabetes Cause Foot Drop Without Pain?

Yes.

Diabetic neuropathy can cause:

• Painful symptoms
• Painless numbness
• Weakness
• A combination

Someone may have substantial loss of sensation or motor function without severe pain.

The absence of pain is not reassuring when:

• The foot is weak
• The skin is damaged
• The foot is hot or swollen
• A blister has developed
• Circulation is reduced

Loss of protective sensation can mean a serious problem is present without causing the expected discomfort.

Can Diabetes Cause Foot Drop Without Numbness?

Potentially.

A focal motor nerve problem may produce noticeable weakness before widespread sensory loss becomes obvious.

Other causes may also be responsible.

A person with diabetes and foot drop but no numbness should still be assessed for:

• Peroneal nerve compression
• Spinal nerve-root compression
• Stroke
• Other neurological conditions

Diabetes should not be used to explain a symptom pattern that has not been properly investigated.

Is Foot Drop Caused by Poor Circulation?

Foot drop is principally a weakness or movement problem related to the nervous system or muscles.

Poor circulation does not usually cause isolated foot drop in the same way as nerve damage.

However, diabetes can affect both:

• Nerves
• Blood vessels

Reduced blood supply can contribute to:

• Cold feet
• Delayed wound healing
• Skin changes
• Leg pain during walking
• Tissue damage

Diabetes UK explains that nerve damage can reduce sensation while blood-vessel damage can make cuts and sores harder to heal.

Both problems matter when fitting an AFO.

How Can You Tell Neuropathy From Poor Circulation?

Symptoms can overlap.

Possible neuropathy symptoms

• Tingling
• Pins and needles
• Burning
• Shooting pain
• Numbness
• Reduced temperature sensation
• Weakness
• Balance difficulty

Possible circulation-related symptoms

• Cold foot
• Colour changes
• Pain in the calf during walking
• Poor wound healing
• Shiny skin
• Reduced hair growth
• Weak pulses

Someone can have both neuropathy and circulation problems.

A professional assessment may include:

• Sensation testing
• Pulse examination
• Skin inspection
• Temperature assessment
• Circulation tests
• Neurological examination

Why Is Reduced Sensation Important?

Reduced sensation means a person may not feel:

• An AFO rubbing
• A tight strap
• A blister
• A folded sock
• A pebble inside the shoe
• Excessive heat
• A cut
• A pressure sore

A problem may continue for hours because it does not hurt.

Diabetes UK warns that loss of feeling can allow minor injuries to progress into infection or ulceration without being noticed.

This makes visual skin checks essential.

Why Can Diabetes Affect Balance?

Balance depends partly on sensory feedback from the feet.

The nervous system needs to know:

• Where the feet are positioned
• How weight is distributed
• Whether the floor is level
• Whether the ankle is moving

Neuropathy can reduce this information.

The person may experience:

• Unsteadiness
• Difficulty in darkness
• Greater reliance on vision
• Difficulty on uneven ground
• Increased falls risk

Peripheral neuropathy can cause loss of balance and coordination as well as muscle weakness.

An AFO may improve foot positioning but cannot restore lost sensation.

Does Diabetes Increase the Risk of Falls?

Diabetic neuropathy can contribute to falls through:

• Muscle weakness
• Reduced sensation
• Poor awareness of foot position
• Foot drop
• Balance problems
• Vision changes
• Dizziness from autonomic neuropathy
• Unsuitable footwear

A complete falls assessment may therefore consider more than dorsiflexion.

Possible interventions include:

• An AFO
• Physiotherapy
• Balance rehabilitation
• A walking aid
• Footwear review
• Vision assessment
• Medication review
• Home-safety changes

How Is Diabetic Foot Drop Diagnosed?

Diagnosis begins by determining whether the person genuinely has foot drop and identifying which part of the nerve pathway is affected.

The clinician may ask:

• When the weakness began
• Whether one or both feet are affected
• Whether onset was sudden or gradual
• How long diabetes has been present
• How diabetes is currently managed
• Whether sensation has changed
• Whether there is back or leg pain
• Whether the legs have been crossed or compressed
• Whether surgery or injury occurred
• Whether there are balance problems
• Whether symptoms are worsening

The examination may assess:

• Ankle dorsiflexion
• Toe extension
• Foot inversion and eversion
• Reflexes
• Sensation
• Pulses
• Skin
• Foot shape
• Knee and hip strength
• Walking
• Balance

What Tests May Be Needed?

Tests may include:

• Blood-glucose testing
• HbA1c
• Blood tests for other neuropathy causes
• Nerve-conduction studies
• Electromyography
• MRI
• Ultrasound
• Spinal imaging
• Circulation assessment

Nerve-conduction studies measure how electrical signals travel through nerves.

Electromyography examines the electrical response of muscles.

These tests can help distinguish between:

• Generalised diabetic polyneuropathy
• Peroneal nerve entrapment
• Lumbar nerve-root compression
• Muscle disease
• Other neurological conditions

Why Should Other Causes Still Be Investigated?

Diabetes is common, and so are unrelated conditions.

A person with diabetes can still develop:

• A slipped disc
• Stroke
• Peroneal nerve injury
• Vitamin B12 deficiency
• Thyroid disease
• Kidney-related neuropathy
• Medication-related neuropathy
• Hereditary neuropathy

Assuming diabetes is responsible may delay treatment of a different condition.

The NHS confirms that peripheral neuropathy has numerous possible causes and that a GP may arrange testing or refer the patient to a neurologist.

Can Better Diabetes Control Improve Neuropathy?

Managing blood glucose, blood pressure and cholesterol can help protect the blood vessels supplying the nerves and may help limit further damage.

Diabetes UK advises keeping blood-glucose levels as close to the agreed target as possible and managing blood pressure and cholesterol to help protect nerve and blood-vessel health.

This does not guarantee that established motor weakness or foot drop will fully reverse.

The goal may include:

• Preventing progression
• Improving symptoms
• Reducing further nerve damage
• Protecting skin and circulation
• Supporting recovery where possible

Follow the targets agreed with your diabetes team rather than making sudden medication changes independently.

Can Diabetic Neuropathy Be Reversed?

The outcome varies.

Some nerve symptoms may improve with:

• Better diabetes management
• Treatment of another contributing cause
• Removal of nerve compression
• Time
• Rehabilitation

In other cases, nerve damage may:

• Remain stable
• Progress
• Become permanent

The NHS notes that some peripheral neuropathies improve when the underlying cause is treated, while others remain permanent or gradually worsen.

An AFO may still provide useful mobility support even when nerve recovery is incomplete.

Can Foot Drop Improve?

Yes, depending on the cause.

Improvement may be more likely when:

• Nerve compression is relieved
• Blood-glucose management improves
• The injury is incomplete
• Muscle function remains
• Rehabilitation is appropriate
• The condition is identified early

Foot drop may remain permanent where:

• Nerve damage is severe
• Neuropathy continues to progress
• Motor fibres are substantially damaged
• Another neurological condition is present

The wearing plan for an AFO should be reviewed as strength changes.

What Treatments May Be Used?

Treatment may involve:

• Diabetes management
• Treatment of another neuropathy cause
• Physiotherapy
• An AFO
• Walking aids
• Balance rehabilitation
• Neuropathic pain medication
• Podiatry
• Footwear advice
• Treatment of nerve entrapment
• Surgery in selected cases

The NHS advises that treatment for peripheral neuropathy depends on the cause and symptoms. Muscle weakness may be managed with physiotherapy and walking aids, while neuropathic pain may require specific prescribed medicines.

Can Physiotherapy Help?

Physiotherapy may help with:

• Ankle range of movement
• Strength in functioning muscles
• Hip and knee strength
• Balance
• Walking technique
• Falls prevention
• Use of an AFO
• Use of a stick or frame
• Maintaining activity safely

Exercises should match:

• The degree of nerve damage
• Sensation
• Ankle movement
• Balance
• Skin condition
• Cardiovascular health
• Other diabetes complications

Exercise cannot immediately repair damaged nerves, but it can support mobility and general function.

Can an AFO Help Diabetic Foot Drop?

Yes, in a suitable wearer.

An AFO may help by:

• Lifting or supporting the forefoot
• Improving toe clearance
• Reducing foot slap
• Creating more consistent foot placement
• Reducing high stepping
• Improving confidence
• Reducing some trip risk

It does not:

• Treat diabetes
• Reverse neuropathy
• Restore sensation
• Heal an ulcer
• Improve circulation
• Guarantee that falls will not happen

The AFO must be selected with particular attention to:

• Skin
• Sensation
• Circulation
• Foot shape
• Swelling
• Footwear
• Ankle stability

Which Type of AFO May Be Suitable?

The appropriate brace depends on the presentation.

Textile support

May suit selected people with flaccid foot drop, a flexible ankle and relatively good side-to-side stability.

Plastic leaf-spring AFO

May provide more consistent mechanical dorsiflexion assistance.

Reinforced AFO

May be appropriate where a lighter leaf spring flexes too much.

Carbon AFO

May provide lightweight structured support for an appropriate foot and walking pattern.

Custom-made AFO

May be needed where there is:

• Foot deformity
• Previous ulceration
• Significant pressure risk
• Severe sensory loss
• Swelling
• An unusual leg shape
• Strong inversion or eversion
• Knee involvement
• Failure of standard braces

Someone with diabetes should not automatically choose the softest support on the assumption that it creates less pressure.

Boxia® as a Low-Profile Option

The Boxia® Drop Foot AFO, SKUs BOX and BBOX, is designed for foot drop caused by flaccid paralysis.

Its features include:

• An adjustable ankle cuff
• Elastic dorsiflexion assistance
• A footwear-connected traction strap
• No conventional full footplate inside the shoe
• Perforated breathable material
• Gel-padded tendon areas
• X Small through Large sizing
• Black and beige options

The product contains latex.

It may suit someone with diabetic foot drop where:

• The weakness is flaccid
• The ankle remains flexible
• Side-to-side stability is adequate
• The skin is healthy
• The cuff can be monitored
• The footwear fits correctly
• A clinician agrees that the support level is sufficient

It may be unsuitable without specialist assessment where there is:

• Active ulceration
• A red, hot or swollen foot
• Severe neuropathy
• Poor circulation
• Significant deformity
• Strong foot inversion or eversion
• Marked swelling
• Severe ankle or knee instability
• Inability to inspect the skin

Does No Footplate Mean No Pressure Risk?

No.

Although Boxia® does not use a full rigid footplate, pressure can still occur beneath:

• The ankle cuff
• Achilles padding
• Traction strap
• Footwear hook
• Shoe upper
• Sock
• Shoe fastening

A low-profile support is not pressure-free.

Anyone with reduced sensation should inspect:

• The cuff area
• Ankle
• Achilles region
• Top of the foot
• Toes
• Areas around the footwear attachment

Should Someone With Diabetes Buy an AFO Without Assessment?

Professional assessment is strongly advisable when diabetes is accompanied by:

• Neuropathy
• Reduced sensation
• Poor circulation
• Foot deformity
• Previous ulceration
• Previous amputation
• Active skin damage
• Significant swelling
• Charcot changes
• Recurrent falls
• Bilateral foot drop

A person with diabetes but normal sensation, healthy skin and a straightforward medically diagnosed flaccid foot drop may still be able to use a suitable prefabricated support.

The decision should be based on the complete risk profile, not the diabetes diagnosis alone.

Can an AFO Be Worn Over an Ulcer?

Do not fit an ordinary AFO over an active ulcer, blister or broken skin without specialist instruction.

Pressure and friction may:

• Enlarge the wound
• Delay healing
• Introduce infection
• Conceal deterioration
• Create new pressure elsewhere

Contact the diabetes foot-protection team, podiatry service or GP.

A specialist may need to provide:

• Offloading
• Wound treatment
• Different footwear
• A custom orthosis
• A temporary mobility plan

What Is Charcot Foot?

Charcot foot is a serious condition associated with neuropathy.

Bones and joints in the foot can become damaged while reduced sensation means the person may not experience the expected pain.

Early signs may include:

• A red foot
• A hot foot
• Swelling
• A change in shape
• A temperature difference between feet

Diabetes UK states that people with diabetes and neuropathy have a greater risk of Charcot foot and advises urgent assessment for a red, hot or swollen foot.

Do not continue walking in an AFO on a suspected Charcot foot.

Take weight off the foot and contact the appropriate foot service urgently.

Why Are Daily Foot Checks Important?

Neuropathy can prevent a person feeling an injury.

Check both feet every day for:

• Redness
• Blisters
• Cuts
• Cracks
• Swelling
• Changes in colour
• Heat
• Cold areas
• Discharge
• Callus
• Pressure marks
• Changes in shape

Use:

• Good lighting
• A mirror
• Help from another person

Diabetes UK recommends daily foot inspection and an annual professional foot check.

Check the Feet Before Fitting the AFO

Before applying the support, inspect:

• Heel
• Ankle bones
• Achilles area
• Calf
• Top of the foot
• Sides of the foot
• Sole
• Toes
• Between the toes

Do not apply the brace if there is:

• A new blister
• Broken skin
• A wound
• Unexplained redness
• Significant swelling
• A hot foot
• A change in shape
• Discharge
• A cold or discoloured foot

Seek advice first.

Check the Feet After Wearing the AFO

Remove the brace and footwear while seated.

Look for:

• New pressure marks
• Redness
• Blistering
• Moisture
• Swelling
• Skin damage
• A change in temperature
• Deep strap indentations

With neuropathy, do not rely on pain to warn you.

NHS diabetic-footwear guidance advises checking the feet every time footwear and socks are removed because rubbing or foreign objects may not be felt.

Check Inside the Shoe

Before putting on footwear:

• Look inside
• Feel inside with your hand where safe
• Check for stones
• Check for folded insoles
• Check for worn lining
• Check for sharp seams
• Check that the AFO foot attachment is positioned correctly
• Check that nothing has penetrated the sole

NHS guidance specifically recommends inspecting the inside and outside of shoes when neuropathy is present.

Wear Suitable Socks

A suitable sock may help protect the skin.

It should generally be:

• Clean
• Dry
• Smooth
• Free from wrinkles
• Free from bulky seams
• Long enough to cover brace-contact areas
• Not so tight that it restricts circulation

Avoid:

• Folded socks
• Damp socks
• Socks with prominent seams over pressure areas
• Socks that bunch beneath the foot
• Tight elastic bands

The exact interface depends on the brace and should follow professional instructions.

Wear Secure Footwear

Footwear should normally have:

• An enclosed heel
• An enclosed toe
• Adjustable laces or touch-close fastening
• Adequate width
• Adequate depth
• A stable sole
• Reliable grip
• Enough room for the brace
• No internal pressure points

Avoid:

• Backless slippers
• Loose slip-ons
• Narrow shoes
• Worn soles
• Shoes that crush the foot or brace
• Footwear that allows the heel to move

NHS diabetic-footwear guidance recommends properly fitted footwear secured by laces, touch-close straps or buckles, particularly where neuropathy increases falls and skin risks.

Should You Walk Barefoot?

Walking barefoot is generally discouraged when sensation is reduced.

A person may not feel:

• Sharp objects
• Heat
• Rough flooring
• A cut
• A splinter
• A burn

Diabetes UK warns that loss of sensation may prevent someone noticing an injury from stepping on an object or developing a blister.

A shoeless foot-drop attachment does not provide the same protection as enclosed supportive footwear.

Introduce the AFO Gradually

A new AFO should be introduced cautiously.

Begin with:

• Shorter wearing periods
• A controlled indoor environment
• Regular skin inspection
• Familiar footwear
• Limited walking

Increase use only when:

• The support remains positioned correctly
• The skin remains intact
• No persistent marks develop
• The heel stays secure
• Toe clearance improves
• The foot does not turn

People with reduced sensation may need a more cautious schedule than someone who can reliably feel rubbing.

What if the Brace Leaves a Red Mark?

Remove it and inspect the skin.

A light temporary mark may occur with a close-fitting support, but concerning signs include:

• Redness that does not fade
• Darkening
• Swelling
• Heat
• Tenderness
• Blistering
• Broken skin
• A mark that returns in exactly the same place

On brown or black skin, pressure damage may not appear as bright redness. Also check:

• Temperature
• Texture
• Swelling
• Firmness
• Dark or purple changes

Stop wearing the brace and seek professional advice if pressure persists.

What if the Foot Is Numb but Looks Normal?

Continue inspecting it regularly.

Numbness means an injury may be present before it becomes visible.

Also monitor:

• Shoe fit
• Sock condition
• AFO position
• Swelling
• Temperature
• Walking changes

Report new or worsening loss of sensation to the diabetes team or GP.

What if the Foot Becomes Red, Hot and Swollen?

Take weight off the foot and seek urgent assessment.

This combination can indicate:

• Charcot foot
• Infection
• Inflammation
• Injury

Diabetes UK advises contacting the local foot team urgently within 24 hours for a red, hot or swollen foot or other serious changes.

Do not continue walking because the foot is not painful.

What if a Blister or Wound Develops?

Stop using any footwear or brace that is pressing on the area.

Do not:

• Burst the blister
• Cut away skin
• Add improvised padding
• Keep walking on the wound
• Wait for pain

Contact:

• Your foot-protection team
• Podiatry
• GP
• An out-of-hours service if necessary

New blisters, cuts or wounds require urgent attention in someone with diabetes, particularly when sensation is reduced.

Can Neuropathic Pain Be Treated?

Yes, although ordinary painkillers may not always work well for nerve pain.

A clinician may prescribe medicines specifically used for neuropathic pain.

Treatment may also involve:

• Diabetes management
• Foot protection
• Sleep support
• Physical activity where appropriate
• Management of mood and wellbeing

The NHS confirms that neuropathic pain may require specific prescribed medicines rather than standard painkillers alone.

Pain treatment does not directly restore lost muscle power.

Can Functional Electrical Stimulation Help Diabetic Foot Drop?

Functional electrical stimulation is mainly used for selected foot drop caused by central neurological damage, such as after stroke or with multiple sclerosis.

Diabetic foot drop usually involves peripheral nerves.

If the peripheral nerve pathway is substantially damaged, FES may not produce an effective muscle response.

A mechanical AFO is often more practical, but treatment should follow specialist assessment.

Do not use a general electrical stimulation machine on a numb lower leg without medical advice.

Can You Exercise With Diabetic Foot Drop?

Often, but the exercise programme should account for:

• Sensation
• Skin
• Circulation
• Balance
• Footwear
• Blood-glucose management
• The underlying cause of weakness
• Other diabetes complications

Possible activities may include:

• Supervised walking
• Strengthening
• Balance exercises
• Seated exercise
• Cardiovascular exercise
• Gait rehabilitation

Stop and inspect the foot if:

• The brace rubs
• A hot area develops
• The foot swells
• Toe catching increases
• Balance deteriorates
• A blister or wound develops

Can You Drive With Diabetic Foot Drop?

Driving safety depends on:

• Which foot is affected
• Strength
• Sensation
• Reaction time
• Pedal control
• The brace
• Vision
• Risk of hypoglycaemia
• Other diabetes complications

Neuropathy may make it harder to judge:

• Pedal position
• Pressure
• Movement between pedals

An AFO may restrict ankle movement or catch in the footwell.

Do not drive if pedal control is unreliable.

Check DVLA and insurer requirements and arrange a specialist driving assessment where needed.

Can Diabetes Cause the Foot to Change Shape?

Yes.

Neuropathy, muscle imbalance and joint changes can contribute to:

• Claw toes
• Hammer toes
• Prominent pressure areas
• Callus
• Altered arch shape
• Charcot changes

Diabetes UK identifies toe deformity, corns, bunions and Charcot foot among concerns associated with diabetic foot problems and neuropathy.

Changes in shape can make a previously suitable AFO or shoe unsafe.

Arrange reassessment if:

• Straps no longer sit correctly
• The footplate no longer fits
• New pressure develops
• The shoe becomes tight
• The heel begins moving

Can an AFO Prevent Foot Ulcers?

No.

A correctly fitted AFO may improve movement and reduce some forms of friction or instability, but it can also create pressure if it is poorly fitted.

Preventing ulceration involves:

• Diabetes management
• Daily foot checks
• Annual screening
• Suitable footwear
• Skin care
• Prompt treatment of wounds
• Pressure management
• Podiatry where required

An AFO should be treated as one part of a wider foot-protection plan.

What Happens During an Annual Diabetes Foot Check?

The healthcare professional may assess:

• Sensation
• Reflexes
• Circulation
• Pulses
• Skin
• Foot shape
• Previous wounds
• Footwear
• Current risk level

Diabetes UK confirms that everyone with diabetes should have an annual foot check as part of their NHS diabetes review.

The annual check does not replace reporting a new problem immediately.

Should You Wait for the Annual Check if Foot Drop Develops?

No.

The annual foot review is intended to screen for risk.

New foot drop is a significant movement problem and requires separate medical assessment.

Diabetes UK advises reporting new or worsening neuropathy symptoms even when routine screening has already been completed.

When Should the AFO Be Reviewed?

Arrange an orthotic, physiotherapy or podiatry review if:

• Toe clearance remains poor
• The cuff slips
• The traction strap repeatedly loosens
• The foot turns inwards or outwards
• The heel moves
• The knee becomes unstable
• The brace causes a pressure mark
• Sensation worsens
• The foot changes shape
• Swelling increases
• Footwear becomes tight
• A blister or wound develops
• The product becomes worn
• Weakness improves or progresses

Take the:

• AFO
• Usual socks
• Everyday shoes
• Walking aid
• Details of any falls
• Photographs of pressure marks

to the appointment.

Simple Diabetic Foot-Drop Checklist

Seek medical assessment if you notice:

• Difficulty lifting the foot
• Difficulty lifting the toes
• Foot slap
• Toe dragging
• Repeated trips
• New weakness
• Worsening balance
• Numbness or tingling
• Burning or shooting pain
• Symptoms affecting both feet
• Pain around the outer knee
• Back or leg pain
• Muscle wasting

Before wearing an AFO:

• Check the skin
• Check the shoe
• Check the sock
• Check the brace
• Confirm the foot is not unusually hot, cold or swollen
• Make sure there is no wound
• Fit the brace while seated
• Use secure footwear
• Begin with short periods
• Inspect the skin after use

When Is a Diabetic Foot Problem Urgent?

Seek urgent help from the diabetes foot-protection team, GP or out-of-hours service if you notice:

• A red, hot or swollen foot
• A new blister
• A cut
• A wound
• Discharge
• An unpleasant smell
• A sudden shape change
• A foot that is much hotter or colder than usual
• Unexplained pain
• Skin discolouration

Take weight off the affected foot while seeking help.

Call 999 or go to A&E if signs of serious infection or sepsis develop, such as confusion, breathing difficulty, very abnormal skin colour or a severe systemic illness.

Can Diabetes Permanently Cause Foot Drop?

Yes.

The outcome depends on:

• Type of neuropathy
• Severity
• Duration
• Diabetes management
• Whether a nerve is compressed
• Whether another condition is involved
• Degree of motor-nerve damage
• Rehabilitation

Some people experience improvement.

Others retain:

• Weakness
• Foot slap
• Reduced sensation
• Balance problems
• A long-term need for an AFO

The brace can support mobility regardless of whether recovery is complete, partial or limited.

Can an AFO Cure Diabetic Neuropathy?

No.

An AFO manages the movement problem caused by weakness.

It does not:

• Repair damaged nerves
• Restore sensation
• Control blood glucose
• Improve circulation directly
• Heal wounds
• Treat infection
• Reverse Charcot foot

Treatment of the underlying diabetes, neuropathy and foot health must continue separately.

When Should You Seek Emergency Neurological Help?

Call 999 if foot or leg weakness begins suddenly with:

• Facial drooping
• Arm weakness
• Speech difficulty
• Confusion
• Sudden loss of balance

These may be symptoms of a stroke.

Seek emergency assessment if weakness occurs with:

• Severe or worsening back pain
• Numbness around the genitals or buttocks
• Difficulty starting urination
• Loss of bladder or bowel control
• Rapidly worsening weakness in both legs

These may indicate serious spinal-nerve compression.

Do not assume that sudden weakness is diabetic neuropathy merely because you have diabetes.
