How to Prevent Pressure Ulcers in Older Adults With Limited Mobility

Editorially reviewed by: A to Zen Therapies Editorial Team in accordance with our Editorial Policy.

Pressure ulcers—also called pressure injuries, pressure sores or bedsores—can develop when sustained pressure, friction or shearing forces damage the skin and deeper tissues.

Older adults with limited mobility may be particularly vulnerable because they may remain in one position for longer, have fragile skin, experience incontinence or have health conditions that affect circulation, sensation, nutrition or healing.

Prevention requires more than buying a special mattress. It involves an individual risk assessment, regular skin inspection, planned repositioning, moisture management, suitable equipment, adequate nutrition and early communication with healthcare professionals.

Family carers should ask a GP, community nurse, tissue-viability nurse, physiotherapist or occupational therapist to develop an individual prevention plan. If skin damage has already appeared, it should be professionally assessed rather than treated solely at home.

Pressure-ulcer prevention should combine individual risk assessment, safe repositioning, skin inspection and appropriate pressure-relieving equipment.

Quick Answer

To reduce pressure-ulcer risk, arrange a professional assessment, help the person change position according to their individual care plan, inspect vulnerable skin regularly and keep skin clean and protected from excess moisture.

Use only properly selected pressure-relieving mattresses, cushions and heel-offloading equipment. Report persistent discolouration, unusual warmth, hardness, pain, blistering or broken skin promptly.

⭐ What Is a Pressure Ulcer?

A pressure ulcer is localised damage to the skin or underlying tissue caused mainly by sustained pressure or pressure combined with shear. It commonly develops over bony areas such as the heels, hips, tailbone, ankles, elbows and back of the head. Damage can also occur beneath medical or mobility equipment.

Key Takeaways

• Limited mobility is an important pressure-ulcer risk, but it is not the only one.

• Repositioning frequency should be individualised—not copied from a generic online schedule.

• Pressure-relieving mattresses and cushions do not eliminate the need to move.

• Skin should be checked for colour, temperature, texture and pain changes.

• Early damage may look purple, blue, darker or unusually shiny on brown or black skin.

• Never rub or massage red, discoloured or damaged pressure areas.

• Continence care should protect the skin without excessive washing or friction.

• Nutrition and hydration needs should be professionally assessed.

• General pillows, beds and chairs are not automatically pressure-relieving equipment.

• An open wound, spreading redness, pus, fever or rapid deterioration needs prompt medical attention.

• Carers should receive training before attempting difficult transfers or repositioning.

Why Do Pressure Ulcers Develop?

Pressure ulcers develop when skin and deeper tissues are compressed for long enough to reduce their tolerance to pressure and damage.

Several forces may contribute:

Pressure

Body weight presses an area against a mattress, chair, footwear, cast or other surface. Bony areas have less cushioning and may be more vulnerable.

Shear

Shear occurs when skin remains against a surface while the deeper tissues move. For example, sliding down in bed can stretch and distort tissues around the tailbone and heels.

Friction

Dragging a person across bedding can rub the outer skin and contribute to damage. Friction is not identical to a pressure ulcer, but it can weaken already vulnerable skin.

Moisture

Urine, faeces, sweat and wound fluid can weaken the skin barrier. Moisture-associated skin damage may coexist with pressure damage, but the conditions require proper assessment because their management is not always identical.

Who Is at Greater Risk?

Risk may be increased by:

• Difficulty changing position independently

• Spending long periods in bed or a chair

• Reduced sensation

• Previous pressure-ulcer history

• Frailty

• Poor circulation

• Diabetes

• Serious illness

• Spinal-cord injury

• Incontinence

• Poor appetite or malnutrition

• Dehydration

• Weight loss

• Significant swelling

• Cognitive impairment

• Sedation

• Pain that limits movement

• Medical devices pressing against the skin

• Recent surgery or hospitalisation

An older adult should not be assumed to have low risk simply because the skin currently appears intact.

A nurse or another trained professional can combine clinical judgement with a structured tool such as Waterlow or Braden. A score should support—not replace—a complete assessment.

📊 Evidence Snapshot: The NICE guideline on pressure-ulcer prevention and management recommends risk assessment, regular repositioning, skin assessment and suitable pressure-redistributing equipment for adults identified as being at risk. NICE provides minimum repositioning intervals for adults assessed as at risk or at high risk, but these are not universal schedules. Frequency should reflect mobility, skin condition, comfort, clinical stability, equipment and individual tolerance.

The NHS overview of pressure ulcers also identifies regular movement, appropriate mattresses and cushions, dressings and infection treatment as important components of prevention and care.

Develop an Individual Repositioning Plan

Changing position reduces the length of time that one area remains under pressure. The safest frequency and technique depend on the individual.

A healthcare professional should document:

• Which positions are safe

• How frequently position should change

• Whether the person can reposition independently

• How much assistance is required

• Which transfer equipment should be used

• Which body areas require offloading

• How sitting time should be managed

• Whether pain relief is needed before movement

• How each position will be recorded

The plan may need revising if mobility, health, skin condition or equipment changes.

Repositioning in bed

Depending on clinical advice, prevention may involve:

• Alternating suitable lying positions

• Keeping pressure off vulnerable heels

• Preventing the person from sliding down the bed

• Using approved positioning equipment

• Keeping bedding smooth and dry

• Checking that tubes and devices are not trapped underneath the body

Do not place the person in a position that compromises breathing, circulation, recent surgery, fractures or other medical conditions.

Repositioning in a chair

Someone who sits for long periods may need:

• A professionally selected pressure-relieving cushion

• Regular weight shifts

• Assisted repositioning

• Review of chair height, depth and width

• Proper foot support

• Limits on uninterrupted sitting time

• Assessment of posture and sliding

A soft-looking chair is not necessarily pressure-relieving. Very soft seats may make movement more difficult or create poorly distributed pressure.

Avoid dragging during transfers

Dragging increases friction and shear. Depending on the person’s abilities, carers may require:

• Slide sheets

• Transfer boards

• Hoists

• Standing aids

• Assistance from a second trained person

Carers should not improvise difficult transfers. A physiotherapist, occupational therapist or moving-and-handling professional can demonstrate safer techniques.

💡 Expert Tip: Check the skin immediately after removing or repositioning cushions, tubing, footwear, splints or continence products. Equipment-related marks can reveal pressure before an open wound develops.

Pressure-Relieving Mattresses, Cushions and Beds

Support surfaces redistribute pressure but cannot remove it entirely. They must be selected according to the person’s clinical needs and regularly checked.

Possible equipment includes:

• High-specification foam mattresses

• Dynamic or alternating-pressure mattresses

• Pressure-redistributing seat cushions

• Heel-offloading devices

• Positioning wedges

• Specialist wheelchair seating

• Adjustable profiling beds

Equipment should be:

• The correct size

• Set up according to the manufacturer’s instructions

• Compatible with the person’s weight

• Checked for damage or faults

• Kept connected to power where required

• Reassessed if the person’s needs change

Do not add ordinary mattress toppers, folded blankets or unapproved cushions on top of specialist equipment unless the clinical team approves them. These additions may interfere with pressure redistribution.

Ring or doughnut-shaped cushions should not be used unless specifically recommended by a qualified professional because they may concentrate pressure around their edges.

Adjustable home-care beds

A profiling bed may assist positioning, personal care and safer transfers, but it is not automatically a pressure-relieving mattress.

Families comparing powered home-care options may encounter products such as the Supernal 3 adjustable home-care bed. The suitability of any bed and mattress combination should be checked with an occupational therapist, community nurse or equipment service before purchase.

The ability to raise the backrest or legs does not by itself prevent a pressure ulcer. Some positions may also increase sliding and shear if used incorrectly.

Lift chairs

Some families use lift chairs for seniors to help a person move between sitting and standing.

A lift chair may reduce physical strain during transfers, but it should not be presented as pressure-relieving equipment unless it includes an appropriately assessed cushion and seating system. A person who remains in the chair for prolonged periods still requires pressure relief and skin monitoring.

Wheelchairs and mobility scooters

A wheelchair or mobility scooter may support independence and transportation, but it can also increase sitting time.

A mobility assessment should consider:

• Seat width and depth

• Cushion type

• Footrest position

• Ability to perform weight shifts

• Posture

• Transfer safety

• Time spent continuously seated

Mobility equipment should complement—not replace—the repositioning plan.

Inspect Vulnerable Skin Regularly

A healthcare professional should explain how often the skin needs checking. The frequency depends on the person’s risk and current skin condition.

Common pressure areas include:

• Heels

• Ankles

• Hips

• Tailbone and buttocks

• Elbows

• Shoulder blades

• Spine

• Back and sides of the head

• Ears

• Knees where they touch

• Areas beneath devices

During inspection, look and feel—without rubbing—for:

• Persistent redness or discolouration

• Purple, blue, maroon or darker patches

• Unusual warmth or coolness

• Firmness or hardness

• Spongy or boggy tissue

• Swelling

• Tenderness or pain

• Shiny skin

• Blisters

• Cracks or broken skin

Recognising changes in darker skin

Redness may be less visible on brown or black skin. Compare the area with the surrounding skin and the opposite side of the body.

Early warning signs may include:

• Purple, blue or darker discolouration

• Changes in temperature

• A firm or spongy texture

• Localised swelling

• Pain or tenderness

• An unusually shiny appearance

Do not wait for obvious redness before reporting other concerning changes.

Heels are common pressure-injury sites and should be checked for changes in colour, temperature, texture, pain and skin integrity.

Skin Cleansing and Moisture Management

Skin should be kept clean, comfortable and protected without excessive washing.

Care may include:

• Cleaning promptly after incontinence

• Using a gentle pH-appropriate cleanser

• Using lukewarm rather than very hot water

• Patting rather than rubbing the skin dry

• Applying an appropriate barrier product

• Changing wet or soiled clothing and bedding

• Reviewing continence products for fit and leakage

• Avoiding strongly perfumed or irritating products

Do not apply talcum powder, antiseptics, essential oils, fragranced creams or home remedies to damaged skin unless a healthcare professional recommends them.

Continence-associated dermatitis may appear as broader irritated areas rather than damage centred over one bony point. However, moisture damage and pressure damage can occur together, so a new rash or wound should be assessed.

Never massage a pressure area

Do not rub or massage skin that is:

• Persistently red or discoloured

• Painful

• Hot

• Firm

• Swollen

• Blistered

• Broken

• Located over a suspected pressure injury

Massage does not restore damaged tissue circulation and may worsen fragile tissue.

Nutrition and Hydration

Poor nutritional intake can increase vulnerability and delay healing, but carers should avoid diagnosing nutritional deficiencies themselves.

Ask for nutritional assessment if the person:

• Has recently lost weight

• Eats very little

• Has difficulty swallowing

• Has poorly fitting dentures

• Frequently refuses food

• Has an existing pressure ulcer

• Has a condition affecting absorption

• Is recovering from serious illness or surgery

A dietitian may recommend a higher-energy or higher-protein eating plan when appropriate.

Protein, calories, vitamins and minerals are all important, but zinc or vitamin supplements should not be started automatically. Excess supplementation can be unnecessary or harmful.

Offer fluids regularly unless the person has been given a fluid restriction because of heart, kidney or another medical condition.

Our Nutrition Hub provides general information about eating well, but an older adult at risk of malnutrition requires individual healthcare advice.

Movement and Rehabilitation

Movement can redistribute pressure and support general function, but it must be safe for the person’s condition.

A physiotherapist may recommend:

• Independent position changes

• Supported weight shifting

• Bed mobility practice

• Transfer training

• Sitting-balance exercises

• Supported standing

• Short assisted walks

• Individual range-of-motion exercises

Do not force a stiff joint or perform generic stretching when the person has severe pain, a recent fracture, surgery, contractures or an unstable medical condition.

For broader mobility information, read A Senior Wellness Guide to Managing Joint Stiffness.

Medical-Device-Related Pressure Injuries

Pressure damage can form underneath or beside:

• Oxygen tubing and masks

• Hearing aids

• Glasses

• Catheters

• Continence products

• Compression garments

• Splints and braces

• Plaster casts

• Wheelchair components

• Feeding tubes

• Monitoring equipment

• Bed rails or positioning straps

Check the skin around devices according to the care plan. Do not reposition, loosen or remove essential medical equipment without understanding how it should be used.

Report a device that rubs, leaves persistent marks, causes swelling or appears incorrectly fitted.

Early Warning Signs and Pressure-Ulcer Categories

Pressure ulcers are classified according to the depth and type of tissue damage, but carers should not try to stage a wound themselves.

Possible early signs include:

• Persistent non-blanching discolouration

• Localised pain

• Heat or coolness

• Firm or boggy tissue

• Purple or maroon skin

• A blood-filled blister

• Broken skin

• A shallow open wound

• A deeper cavity or visible tissue

Deep damage can begin beneath apparently intact skin. A dark purple area or blood-filled blister may therefore be more serious than it first appears.

Remove pressure from the area and contact an appropriate healthcare professional promptly.

When to Seek Medical Attention

Request prompt clinical assessment for:

• Persistent redness or discolouration

• A new blister

• Broken skin

• Increasing tenderness or pain

• A dark purple or maroon area

• A wound that is enlarging

• New damage beneath a device

• An unpleasant smell

• Fluid, pus or bleeding

• Black or dead-looking tissue

• Concerns that equipment is no longer suitable

Seek urgent medical help if the person develops:

• Fever or chills

• Spreading redness or swelling

• Rapidly increasing pain

• Pus or significant discharge

• Confusion or unusual drowsiness

• Rapid breathing or deterioration

• Signs of severe infection

• Skin that becomes black, cold or rapidly damaged

Do not place an ordinary sticking plaster over a suspected pressure ulcer or apply unprescribed wound products. Dressings should be selected according to professional wound assessment.

Supporting Carers and Maintaining Dignity

Pressure-ulcer prevention can involve frequent observation, personal care and physically demanding transfers. The person receiving care should be included in decisions wherever possible.

Explain:

• Why skin is being checked

• Why position changes are needed

• What equipment is being used

• How privacy will be protected

• Which positions are comfortable

• Who should be contacted when concerns arise

Carers should also ask for:

• Moving-and-handling training

• Written repositioning instructions

• Equipment demonstrations

• Community-nursing support

• Continence assessment

• Respite care where available

• Help if the current care plan is no longer manageable

How A to Zen Therapies Can Help

A to Zen Therapies does not provide pressure-ulcer prevention plans, wound assessment, dressings or tissue-viability care.

Massage, acupuncture, cupping and manual lymphatic drainage must not be performed over a pressure ulcer, suspected pressure damage, fragile inflamed skin or an area affected by infection.

If an older adult has limited mobility, medical devices, fragile skin or a history of pressure ulcers, obtain clearance from the person’s healthcare team before arranging complementary treatment.

Family carers experiencing everyday muscular tension may consider a relaxing massage in

London for their own wellbeing. This does not replace respite services, moving-and-handling training or medical support.

Frequently Asked Questions

How often should an immobile older adult be repositioned?

There is no universal schedule suitable for everyone. The frequency should be based on a professional risk assessment, skin condition, health, support surface and ability to move independently.

Does a pressure-relieving mattress remove the need to turn someone?

No. Specialist mattresses redistribute pressure but do not usually eliminate the need for position changes and skin inspection.

Can I massage red skin to improve circulation?

No. Do not rub or massage red, discoloured, painful, hard or damaged pressure areas. Remove pressure and seek professional advice.

What is the first sign of a pressure ulcer?

An early sign may be persistent discolouration, pain, heat, coolness, firmness or a spongy texture. On darker skin, redness may be difficult to see.

Where do pressure ulcers commonly develop?

Common sites include the heels, ankles, hips, tailbone, elbows, shoulder blades and back of the head. They can also develop beneath medical devices.

Are all pressure ulcers preventable?

Many risks can be reduced through good care, but pressure ulcers can still occur in people who are very ill or medically vulnerable despite appropriate preventive measures.

Can ordinary cushions prevent pressure ulcers?

Not necessarily. Cushions should be selected for the individual by an appropriately trained professional. An unsuitable cushion may create additional pressure or instability.

Should zinc or vitamin C be taken for prevention?

Not routinely without professional advice. A healthcare professional or dietitian should assess overall food intake, weight changes, medical conditions and possible deficiencies.

Who should assess a suspected pressure ulcer?

Contact a GP, community nurse, district nurse, tissue-viability nurse or the person’s existing healthcare team. An open or rapidly deteriorating wound needs prompt assessment.

Is pressure-ulcer prevention only about the skin?

No. Effective prevention also involves mobility, nutrition, hydration, continence care, circulation, pain management, medical devices and appropriate support surfaces.
