Foot Care in Older Age: Effectively Preserving Independence and Mobility

What lies behind it

The human ageing process leaves distinct marks on the lower extremities. As age increases, the anatomy and physiology of the skin, nails, and entire musculoskeletal system undergo systematic changes. The epidermis loses moisture because sebaceous and sweat gland activity steadily declines. At the same time, the dermis thins, causing the skin to lose elasticity and become more susceptible to microtrauma. A particularly critical factor is the atrophy of the subcutaneous fat pad beneath the metatarsal heads, which are the balls of the feet. This natural shock-absorbing system shrinks with age, causing mechanical pressure loads during walking to be transferred directly to the periosteum and underlying tissue layers.

In parallel, the mechanical properties of the toenails change. Reduced capillary perfusion in the nail bed and slowed cell growth often lead to considerable thickening of the nail plates. These keratinisation disorders, medically termed onychauxis, or onychogryphosis when claw-like deformities occur, make normal trimming severely difficult. Furthermore, mobility in the ankle joints and flexibility in the interphalangeal joints decline. Osteoarthritic changes in the subtalar joint and the first metatarsophalangeal joint restrict the roll-over movement of the foot.

Alongside orthopaedic and dermatological factors, neurophysiological components play a central role. The density of Meissner corpuscles and Pacinian corpuscles, which are responsible for vibration sensation and fine pressure perception in the sole of the foot, decreases with age. Consequently, the receptors in the plantar surface send less precise signals to the central nervous system. Combined with reduced visual acuity, for instance due to cataracts or diabetic retinopathy, postural control deteriorates. The body becomes less able to compensate for fluctuations in its center of gravity. Any unnoticed painful point on the sole of the foot triggers a reflex evasive movement, placing additional strain on the biological balance system.

Typical signs

Changes in the feet usually manifest insidiously in old age. Those affected often notice first that putting on socks or sturdy footwear becomes uncomfortable. The occurrence of pronounced hyperkeratoses, which are widespread callus thickenings on the primary weight-bearing zones of the heel and forefoot, is typical. When these calluses dry out, deep fissures or rhagades develop. These skin cracks are not only painful, but also serve as entry points for bacterial pathogens.

Localised pressure points frequently lead to the formation of clavi, commonly known as corns. Here, a central keratin core presses deep into the tissue, impinging on sensitively innervated dermal layers. Fungal changes in the nail plate, known as onychomycosis, are also frequently observed. The nail turns yellowish to brownish, becomes brittle, or crumbles during attempts to trim it. If the nail plate curves excessively inwards, onychocryptosis, an ingrown nail, threatens to develop, leading to painful inflammation of the nail fold.

Such complaints can be detected early from the gait pattern. Painful feet prompt older individuals to avoid rolling off the foot. The gait becomes shuffling, step length decreases, and base width increases to gain a larger standing surface. These gait deviations alter the biomechanics of the knee and hip joints. These complaints differ from purely age-related wear and tear in that they can be directly and positively influenced by targeted pressure relief and professional tissue debridement. By contrast, in arterial circulatory disorders, the skin appears pale, cool, and hairless, whereas in venous drainage disorders, the tissue tends towards oedema.

An 82-year-old female patient reported in our practice recurring unsteadiness when walking, which she attributed to general weakness in old age. During the podiatric examination, a deep-seated callus zone hidden beneath a thick hyperkeratotic layer was found under the second metatarsal head. Just a few minutes after professional pressure relief at this site, the patient was able to walk again pain-free and with a full heel strike.

Everyday causes

The triggers for foot complaints in older age are complex and mutually reinforcing. A key cause lies in the choice of inappropriate footwear. Shoes worn over decades that are cut too narrow in the toe area encourage the development of toe deformities such as hallux valgus, hammer toes, and claw toes. In old age, many senior citizens turn to soft, unstructured slippers without heel support. While these shoes offer a comfortable slip-in feel, they lack any guiding properties for the ankle joint and significantly increase the risk of falls.

Another central factor is the physical inaccessibility of the feet. Mobility restrictions due to knee or hip osteoarthritis, spinal stiffness, or obesity prevent the foot from being reached easily with the hands. If those affected nevertheless attempt to trim their nails themselves, this often happens from awkward angles and under inadequate lighting. If adequate hand strength is also lacking, or fine motor skills are impaired by a tremor, injury inevitably occurs.

Care errors also contribute to the deterioration of skin condition. The use of sharp callus planes, coarse pumice stones, or unsuitable household scissors damages the fragile tissue. Many older people also use excessive foot baths. A prolonged soak in very warm water severely softens the stratum corneum, the outermost layer of skin. As a result, the skin loses its natural nutrients and dries out even more after the bath. If the interdigital spaces remain damp afterwards, this creates an ideal breeding ground for dermatophytes.

Chronic underlying conditions such as diabetes mellitus, peripheral arterial disease, or rheumatic joint changes aggravate the situation. They reduce perfusion, lower pain perception, or lead to progressive joint stiffening that creates biomechanical overload on the foot.

When medical assessment is required

Not every change in the foot may be treated exclusively by a podiatrist. Clear medical warning signs exist that require an immediate assessment by a physician. These include:

• Open wounds, lesions, or deep tissue tears that show no tendency to heal
• Signs of local or spreading infection such as severe redness, local hyperthermia, swelling, pustule formation, or pronounced tenderness
• Sudden or rapidly worsening skin discolouration, particularly dark, blue, or black tissue areas indicating necrosis
• Rest pain in the feet or lower legs, especially when elevating the legs in bed
• Loss of tactile or pain perception in the feet, where injuries are no longer noticed at all

In these cases, interdisciplinary collaboration between podiatry, general practice, diabetology, dermatology, or vascular surgery is essential. When underlying conditions such as diabetic foot syndrome are present, appropriate medical assessment forms the foundation for any further treatment.

What podiatric treatment can achieve

Professional podiatry serves as the interface between purely nursing measures and medical therapy. In our modern practice, we first carry out a detailed medical history and a visual and palpation inspection of the feet. Skin condition, trophic status, pulse status of the dorsalis pedis artery and posterior tibial artery, as well as the presence of pressure points are precisely documented. Detailed information about our medical spectrum can be found under /en/services.

The podiatric treatment routine differs fundamentally from cosmetic foot care. Trimming the nails is performed atraumatically and anatomically correctly using specially hardened instruments. Thickened nail plates are thinned painlessly to normal plate thickness using rotary diamond burrs. Care is taken to completely clear the nail fold of horny material and hyperkeratoses without injuring the sensitive skin barrier.

For the removal of calluses and the painless removal of corns, we use precise scalpel techniques and special gouge blades. Expert guidance of the scalpel allows horny skin layers to be debrided with millimetre precision while healthy tissue remains untouched. If involuted nails or deformed nail plates are present, nail brace therapy, known as orthonyxic treatment, can permanently relieve pressure from the nail bed. In cases of mechanical overload, we fabricate individually fitted orthoses made of medical-grade silicone to redirect pressure away from the phalanges.

Hygiene standards are of the highest priority in podiatry. Following each treatment, all rotary and cutting instruments undergo a reprocessing protocol certified according to the guidelines of the Robert Koch Institute, comprising ultrasonic cleaning, chemical disinfection, and autoclave sterilisation. We explain further details regarding our hygiene concept at /en/hygiene. A podiatric treatment session typically lasts between 30 and 45 minutes. For older adults, a regular treatment interval of four to six weeks has proven effective in identifying changes early and permanently safeguarding mobility.

What you can do yourself

Even if personal mobility or visual acuity is impaired, effective strategies exist to support foot health in daily life. The most important element is daily visual inspection of the feet. If bending down is difficult, a telescopic mirror with an adjustable handle or a cosmetic mirror placed on the floor can be used. Alternatively, family members or caregivers can be asked to take a brief look at the soles of the feet and heels.

For daily hygiene, brief washing with lukewarm water and a mild, lipid-replenishing soap is recommended. The water temperature should be checked beforehand using the forearm or a bath thermometer to prevent burns in the event of impaired temperature perception. After washing, the interdigital spaces must be dried thoroughly. A soft towel or a hair dryer on a cool air setting helps eliminate moisture and prevent fungal infections.

Skin care requires products tailored specifically to the needs of ageing skin. Creams containing a 10 percent urea concentration bind moisture in the deeper layers of the stratum corneum and keep the tissue supple. The spaces between the toes should be left uncreamed to prevent maceration of the skin. If self-cutting of nails becomes unsafe due to poor vision or tremor, the use of scissors or clippers should be abandoned entirely. Gentle filing with a glass or cardboard nail file is significantly safer.

Equally important is choosing the right indoor footwear. Slippers should feature a firm heel cap, a non-slip rubber sole, and adjustable hook-and-loop fasteners. This provides the foot with necessary stability and significantly minimises the risk of slipping accidents on smooth tiles or parquet flooring.

Common errors

In daily podiatric practice, we regularly encounter home care mistakes that were initiated with good intentions but can lead to severe complications. The use of over-the-counter corn plasters is foremost among these. These plasters usually contain highly concentrated salicylic acid intended to chemically dissolve hyperkeratotic tissue. However, because the acid does not distinguish between calloused and healthy skin, it frequently leaks into the surrounding tissue. In older, thin skin, this often results in deep chemical burns and slow-healing ulcerations.

Another serious error is cutting toenails round, deep into the lateral nail folds. Many individuals attempt this to relieve pressure at the nail borders. However, this measure leads to the regrowing nail piercing directly into the soft tissue wall with its sharp edge, causing severe inflammation. Toenails should always be trimmed straight across, with the corners smoothed only minimally.

Using sharp instruments such as razor blades, metal rasps, or callus planes carries an enormous risk of injury. A brief slip is enough to injure deeper skin layers. Wearing compression stockings that are too tight, where the top band digs into the lower leg or rolls down, also impairs arterial blood supply and exacerbates tissue damage to the feet.

Neglecting minor microtraumas also has severe consequences. A small pressure mark caused by a foreign object in the shoe often goes unnoticed for days when nerve conduction is diminished. The damage is only recognised once the shoe is discoloured or a sweetish odour develops. Palpating the inside of shoes daily before putting them on is a simple measure that effectively prevents such damage.

Current scientific evidence

The importance of preventive and therapeutic foot care for fall prevention and maintaining quality of life in old age is well documented by numerous international scientific studies. A landmark randomised controlled trial by Spink and colleagues [1] investigated the effect of a tailored podiatric intervention programme on fall frequency in older people. The programme included targeted treatment of nail and skin lesions, provision of orthotic insoles, foot exercises, and advice on footwear selection. The results demonstrated a significant 36 percent reduction in the fall rate in the treatment group compared with the control group.

A systematic review by Stolt et al. [2] illustrated that foot pain, nail plate thickening, and pronounced callus formation in older adults are directly linked to impaired postural stability. The authors highlighted that the presence of foot complaints increases step variability, which is considered an independent predictor of falls. Further work by Menz and colleagues [3] demonstrated that even minor podiatric lesions, such as irregularly grown nails or painful clavi, alter roll-over mechanics so severely that thigh and hip muscle activity must increase compensatorily, leading to rapid fatigue when walking.

Additionally, Mickle et al. [4] showed that reduced toe flexor strength and toe deformities double the risk of falls in the home environment. The researchers emphasized the necessity of treating structural foot problems early using podiatric aids and targeted pressure-relief therapies in order to optimize sensory feedback from the sole of the foot to the brain. In summary, the current body of scientific evidence underlines that professional foot care goes far beyond mere symptom management and holds an established place in geriatric preventive care.
