What is falls prevention from a functional approach and what are its objectives?
From a functional approach, falls prevention involves analysis of and intervention on the interaction person-task-environment. It is not just about measuring risk, but about understanding how strength, balance, gait, vision, attention and habits combine with the demands of specific activities (lifting, turning, using stairs) and the characteristics of the environment (lighting, surfaces, access). This approach prioritises safe practice of meaningful tasks, risk education and gradual changes, with realistic expectations and follow-up.
The intervention is based on a multifactorial assessment of modifiable factors (physical capacity, medication and polypharmacy, orthostatic hypotension, pain, foot and shoe health, vision and hearing, cognitive status and fear of falling), together with the detection of environmental barriers at home and in the community. Measures typically include adaptation of the environment (lighting, removal of obstacles, supports), task and balance training with cautious progression, compensatory strategies (pace management, visual support, pauses), and correct selection and adjustment of technical aids where relevant, coordinating with the responsible professionals.
Objectives pursued
- Decrease the likelihood of falls in everyday activities by making adjustments to the task and environment, without creating overconfidence.
- Maintain or improve the functional capacity (gait, balance, transfers) within individually defined safety margins.
- Encourage autonomy and participation in daily life, balancing challenge and security to avoid deconditioning.
- Reduce the potential severity of injuries through choice of footwear and aids, training in protective strategies and space planning.
- Detect and periodically reassess modifiable risk factors, adjusting interventions according to clinical or contextual changes.
- Promote informed self-management and coordination with carers and professionals for a coherent response to incidents and falls.
Functional falls risk assessment: mobility, balance, vision and medication
Functional assessment focuses on the mobility and the balance. Gait pattern (speed, stride length, double support, turning), ability to get up and sit without using hands, and the need for assistive devices are assessed. Common clinical tests include Timed Up and Go (TUG), getting out of the chair in 30 seconds and static (unipodal support, Romberg) and dynamic (turning, changes of direction) balance tasks. It is relevant to explore proximal strength (hip and knee extensors), joint range, pain, proprioceptive sensitivity and signs of peripheral neuropathy, as alterations in these domains are associated with increased likelihood of falls.
The vision is assessed beyond acuity: contrast sensitivity, visual field, depth perception and glare tolerance influence postural stability. Frequent disorders (cataracts, macular degeneration, diabetic retinopathy or glaucoma) and the use of multifocal lenses can make it difficult to detect edges and changes in level, especially on stairs. Checking optical correction, lens fitting and visual quality in low light conditions provides useful clinical information to estimate risk.
The medication is reviewed with a focus on safety, identifying drugs that increase drowsiness, dizziness, hypotension or hypoglycaemia. CNS depressants (benzodiazepines, hypnotics, antipsychotics, opioids), anticholinergics, antihypertensives with potential for orthostatic hypotension, diuretics (for urgency/nicturia) and hypoglycaemics are particularly considered. The polypharmacy, In addition, high doses, interactions and alcohol consumption are associated with increased risk; documenting symptoms such as unsteadiness after postural changes or presyncopal episodes helps to relate pharmacological effects to functional performance.
Exercises and activities of daily living to prevent falls from a functional approach
Functional principles and security
A functional approach prioritises tasks that replicate real day-to-day demands in order to reinforce the lower limb strength, the dynamic equilibrium, the postural control and the management of the dual task (moving while attending to another action). Progression is usually based on gradually increasing the demand (time in support, range of motion or complexity of the environment) while maintaining stable technique and pain free. It is prudent to perform the exercises close to a fixed support, with sufficient lighting and avoiding marked fatigue, dizziness or acute pain. People with significant instability, recent fall episodes or neurological diseases may require prior individual adaptation.
Key functional exercises
Priority is given to multi-joint movements under load, with control of the centre of gravity and changes of support similar to those performed at home.
- Sit and rise from a chair with arm support if necessary, taking care of knee alignment and descent control.
- Heel and toe lifts next to a worktop to work on ankle and postural adjustment; progress from bipodal to alternating support if there is good control.
- Low step-ups and lateral weight shifts, promoting pelvic stability and controlled propulsion.
- Semi-tandem or tandem balance and short unipodal support with close support; add slow turns of 90-180° when control permits.
- Functional reach at different heights (front and side) while maintaining a broad base of support and forward gaze.
- Hip hinge and ankle mobility under load to improve the flexion/stretch strategy without collapsing the trunk.
Trainable activities of daily living
Structured practice of daily tasks aims to improve movement efficiency and postural anticipation, prioritising technique and controlled rhythm over speed.
- Aisle gait with voluntary starts and stops, U-turns and carrying a light object at abdominal height without compromising the base of support.
- Safe transfers (bed-chair-toilet), ensuring full foot contact, use of available supports and stable sequence of sitting and standing.
- Ascent and descent of stairs with handrails, practising the most stable pattern according to physical condition and avoiding sudden changes of direction.
- Reach for objects on low/high shelves using wide base, hip hinge and stable support; for floor, prioritise knee support or use of reach clamp if limited.
- Dual functional task: walking by counting steps or naming categories, or turning the head to locate landmarks while keeping short, regular steps.
- Proper fitting of closed shoes with non-slip soles before walking or transfers, checking fit and laces.
Home environment and technical aids: adaptation with a functional approach to reduce the risk of falls
A functional environment seeks to adapt the home to the person's abilities and habits in order to reduce the risk of falls in everyday tasks (getting up, hygiene, cooking, moving around). This approach prioritises the elimination of barriers and the simplification of routes in areas of greatest exposure such as bathrooms, corridors, stairs and bedrooms. Prudent measures are those that improve visibility and reduce the need for demanding manoeuvres: continuous lighting and homogeneous (including night or sensor lights), tidiness and accessibility of frequently used objects at hip height, and removal of clutter (cables, loose carpets, low furniture).
- Soil: anti-slip surfaces in bathrooms and kitchens; contrasting or anti-slip strips on step edges; levelling of thresholds where possible.
- Stairs and corridors: handrails and handholds (preferably on both sides of stairs), clear aisles with sufficient width and good directional lighting.
- Bathroom: safe placement of grab bars, stable shower seat, non-slip mat inside and outside the shower, and toilet seat at a height compatible with strength and joint range.
- Bedroom: bed height that allows both feet to be supported before getting into bed, light accessible from the bed and bedside table uncluttered; closed and stable shoes within reach.
- Signage and contrast: switches and step edges with visual contrast; consistent organisation to minimise errors and sharp turns.
The technical aids (e.g., baton, walker, toilet seats, toilet risers, handholds) can contribute if they are selected with individual adjustment and are used with proper technique. Their effectiveness depends on the choice of model according to gait pattern and environment, proper installation (anchors in a sturdy wall, spikes or tips in good condition) and regular maintenance. It is prudent to review fit when vision, medication or strength changes, and to train safe turning, transfer and use routines in real home spaces to reduce complex or unexpected manoeuvres.
Interdisciplinary work and clinical follow-up in falls prevention with a functional approach
Interdisciplinary coordination with a functional approach
Functional fall prevention is based on a functional approach to fall prevention. comprehensive geriatric assessment and in the definition of functional objectives relevant to the person. Coordination between medicine (primary care or geriatrics), physiotherapy, occupational therapy, nursing, pharmacy, nutrition, ophthalmology/podiatry, social work and psychology allows identification of intrinsic and extrinsic risk factors and prioritisation of interventions proportionate to risk, clinical condition and living environment.
- Physician/geriatrician: differential diagnosis of falls, management of comorbidities, pharmacological review and deprescription where appropriate, assessment of orthostatic hypotension and syncope.
- Physiotherapy: assessment of balance and gait; prescription of multicomponent exercise (strength, balance, gait) and training of technical aids.
- Occupational therapy: analysis of activities of daily living, transfer training and adaptation of the environment (lighting, handrails, removal of obstacles).
- Nursing and pharmacy: clinical monitoring, education in self-care, medication reconciliation and detection of drugs at risk of falls (sedatives, anticholinergics, antihypertensives in certain circumstances).
- Nutrition, ophthalmology/podiatry, social work/psychology: nutritional support according to functional status, vision and foot/foot assessment, addressing fear of falling and social barriers.
Clinical monitoring and functional metrics
Follow-up is planned, continuous and individualised. It includes a baseline and reassessments at intervals adjusted for risk, clinical changes or recent events. Progress is documented and interventions are adjusted to maintain safety and participation in meaningful activities.
- Functional metricsTimed Up and Go, gait speed, chair rise tests (5 repetitions or 30 seconds), SPPB, balance scales (e.g. Berg) according to clinical relevance.
- Clinical parameters: orthostatic blood pressure, heart rate, pain, neuromuscular and sensory status when indicated.
- Pharmacotherapy: recent changes, adverse effects (sedation, hypotension, dizziness), anticholinergic burden.
- Environment and devices: shoe fitting, walking aids and home modifications.
- Events: structured recording of falls and near-falls (context, triggers, consequences) to feed back into the plan.
- Participation and perception: performance in activities of daily living and confidence to move around.
- Adherence and tolerance to exercise: progression, fatigue, pain or unwanted effects.
Decision-making is prudent and person-centred: gradual progression of exercise, monitoring for warning signs (e.g. syncope, acute neurological deterioration), and adjustments when clinical status or priorities change. Structured communication between professionals and caregivers supports consistent and coherent interventions consistent with agreed functional goals.
