Fall prevention and bone health are two sides of the same fracture prevention coin — yet they are often addressed separately, if at all. Treating osteoporosis with bisphosphonates without addressing falls risk leaves patients exposed to the proximate cause of most hip and wrist fractures. Equally, reducing falls risk through exercise and medication review without treating low bone density leaves the skeleton vulnerable to fracture if a fall does occur. The most effective fracture prevention strategy in older adults addresses both simultaneously — and the evidence shows that doing so produces a larger fracture risk reduction than either approach alone. This guide covers the evidence-based falls prevention interventions — exercise, medication review, home safety, vision care, vitamin D — and how they work alongside osteoporosis treatment to reduce the probability of the fracture events that most strongly predict disability, loss of independence, and premature death in older adults.
Why Falls Matter for Bone Health
Approximately 30% of adults over 65 fall at least once per year, and 10% of falls cause a serious injury — fracture, head injury, or soft tissue injury requiring hospital attendance. The vast majority of hip fractures and a substantial proportion of wrist and shoulder fractures in older adults result from a fall rather than from spontaneous failure of the bone under normal loading. This means that even a person with severe osteoporosis who never falls may never sustain a hip fracture, while a person with only moderately reduced bone density who falls frequently may fracture.
The relationship between falls and bone density is multiplicative, not additive. A single fall in someone with normal bone density is very unlikely to cause a hip fracture; the same fall in someone with a T-score of −3.0 is far more dangerous. This multiplicative relationship explains why falls prevention provides large absolute fracture risk reductions in older adults with osteoporosis — far larger than the purely theoretical bone-density-based models might suggest — and why it is recommended as a core component of osteoporosis management in every major clinical guideline. NICE CG161 (Falls in older people: assessing risk and prevention) and NICE CG146 (Osteoporosis) both address falls prevention as an integral part of fracture prevention, not a separate concern. Our guide to fracture risk: what adults should know covers the evidence base for combined bone-density and falls-risk assessment.
Who Is at Highest Falls Risk?
The key risk factors for falls in older adults are well-characterised. Identifying individuals with multiple risk factors — who have a disproportionately higher fall probability — is the basis of targeted falls prevention assessment:
- Prior fall: Two or more falls in the past year, or one fall causing injury, is the strongest single predictor of future falls
- Gait and balance impairment: Unsteady gait, slow walking speed, difficulty with turns, and abnormal balance on the Timed Up and Go test all predict fall risk
- Muscle weakness: Lower limb muscle weakness, particularly reduced quadriceps strength (difficulty rising from a chair without arm support), correlates strongly with falls risk
- Polypharmacy: Taking 4 or more medications increases falls risk; specific drug classes (see below) raise risk further
- Visual impairment: Reduced visual acuity, cataracts, and depth perception problems impair hazard detection and balance
- Cognitive impairment: Attention impairment, reduced hazard awareness, and gait disturbance in dementia all increase falls risk
- Postural hypotension: Drop in blood pressure on standing (orthostatic hypotension) causes transient dizziness or lightheadedness, a common cause of falls particularly after meals or after standing from a chair
- Environmental hazards: Loose rugs, poor lighting, absence of stair rails and bathroom grab bars, cluttered walkways
Adults with two or more of these risk factors should discuss falls prevention assessment with their GP. In England, GP practices are incentivised under the Quality and Outcomes Framework to identify and assess older adults at falls risk, and community falls prevention programmes are available in most areas through NHS referral. A formal falls risk assessment typically includes the Timed Up and Go test (walking 3 metres, turning, and returning — a time above 12–14 seconds indicates high falls risk), a medication review, and a postural blood pressure measurement. The GP may also refer to community physiotherapy for a more comprehensive assessment of gait, balance, and lower-limb strength, particularly if the initial assessment identifies multiple risk factors.
Exercise — The Most Effective Single Intervention
Exercise is the most evidence-supported falls prevention intervention available in community-dwelling older adults. A 2019 Cochrane meta-analysis of 108 trials involving over 23,000 participants found that exercise reduced falls rate by 23% overall, with specific exercise types showing larger effects:
- Balance and functional training: 24% reduction in falls rate (standing on one leg, tandem walking, stepping exercises, balance boards, functional tasks)
- Tai chi: 19% reduction in falls rate in the Cochrane analysis; individual trials including the ACTSO trial report up to 29% reduction; particularly effective because it combines balance training with body awareness and slow, controlled movements
- Resistance training alone: Modest reduction; more effective when combined with balance training
- Combined balance and resistance training: The most effective exercise combination — the Royal Osteoporosis Society recommends this as the standard exercise programme for falls prevention in older adults with bone health concerns
The key principle of effective falls prevention exercise is specificity: exercises that directly train the balance and muscle reactions needed to prevent a stumble from becoming a fall (stepping exercises, perturbation training, narrowing base of support, standing on one leg, heel-to-toe walking) are more effective than general aerobic exercise. The Royal Osteoporosis Society’s Strong, Steady and Straight report recommends a minimum of 50 hours of balance and functional exercise per year (roughly 1 hour per week) to achieve meaningful falls risk reduction — a threshold that requires a structured programme rather than incidental activity. A supervised group-based falls prevention class or a physiotherapist-directed home programme provides more effective balance training than self-directed walking alone, though walking remains a valuable baseline activity that keeps lower-limb strength and cardiovascular fitness from declining further. Our guide to bone health after age 60 covers exercise for both bone density and falls prevention in older adults.
Medication Review — An Underappreciated Falls Risk
Medications are a major and modifiable falls risk factor in older adults, yet medication review is one of the least frequently addressed components of falls prevention in clinical practice. Several drug classes are particularly associated with increased falls risk:
Sedating medications: Benzodiazepines (diazepam, lorazepam, temazepam), Z-drugs (zopiclone, zolpidem), sedating antihistamines (chlorphenamine, promethazine), and opioid analgesics all impair alertness, reaction time, and balance — and increase falls risk substantially. Even short-term or as-needed use increases falls risk, particularly in the hours after taking the medication. Many older adults are on these medications long-term for conditions (sleep, anxiety, pain) where non-pharmacological alternatives have not been adequately explored.
Antidepressants: Both tricyclic antidepressants and SSRIs are independently associated with increased falls risk. The mechanism for SSRIs is not entirely clear — serotonin receptors in the basal ganglia and cerebellum play a role in movement coordination, and SSRIs appear to affect balance control beyond any sedation effect. NICE CG161 recommends falls risk assessment for older adults on any antidepressant.
Antihypertensives: Blood pressure-lowering medications can cause orthostatic hypotension — particularly alpha-blockers, diuretics, and ACE inhibitors taken in combination. Standing from a chair or getting out of bed triggers a transient drop in blood pressure in patients on these medications, causing dizziness or presyncope that can precipitate a fall. Reviewing antihypertensive combinations and considering dose reduction in older adults with falls risk is recommended in NICE CG161.
A medication review by a GP or pharmacist specifically focusing on falls-risk medications is recommended for any older adult who has fallen, and for those being assessed for high fracture risk. Stopping, reducing, or switching medications that carry unnecessary falls risk can substantially reduce fall frequency.
Home Safety Assessment
The home environment is the site of approximately 50% of falls in older adults — and many of the fall hazards in the home are straightforward to address with low-cost modifications. An occupational therapist (OT) home safety assessment identifies hazards and recommends modifications:
- Removing loose rugs, especially in high-traffic areas and at the tops and bottoms of stairs
- Improving lighting — night lights on the route from bedroom to bathroom, brighter bulbs throughout
- Installing grab rails in the bathroom (next to the toilet and in/around the shower or bath)
- Securing trailing wires and cables
- Rearranging storage so frequently used items are at accessible heights (not requiring reaching up or bending down)
- Reviewing footwear — firm-soled, well-fitting shoes with a low heel; avoiding socks or slippers without grip on smooth floors
OT home safety assessment is available on NHS referral for older adults at high falls risk. Cochrane evidence suggests that targeted home hazard modification reduces falls by approximately 19% in community-dwelling older adults at high risk — a meaningful reduction that costs relatively little to implement. Our guide to hip fractures in older adults covers the relationship between home environment and hip fracture risk in more detail.
Vision, Footwear, and Other Modifiable Factors
Vision: Poor visual acuity is a significant falls risk factor that is frequently under-addressed. An up-to-date glasses prescription, cataracts surgery when indicated, and ensuring adequate lighting all reduce falls risk. One systematic review found that cataract surgery in the first eye reduces falls rate by 34%. Adults over 65 who have not had a vision test in the past two years should arrange one — optometrists are accessible without GP referral, and glasses on a current prescription are available on the NHS for those who qualify.
Footwear: Thin-soled slippers without heel support and going barefoot on smooth floors are associated with increased falls risk. Firm-soled shoes with low heels, adequate toe box width, and non-slip soles provide the most stable foot platform for older adults. Avoiding bifocal or varifocal glasses on stairs (where depth perception adjustment is impaired) is also recommended.
Foot care: Foot problems — bunions, toe deformities, reduced sensation from peripheral neuropathy (common in diabetes), and thick toenails — impair proprioception, balance, and the ability to respond to uneven surfaces. Regular podiatry review for older adults with foot problems is worthwhile from a falls prevention perspective. Well-fitting shoes with a firm sole, low heel, and secure fastening (laces or Velcro, not slip-ons) provide the most stable foot platform.
Postural hypotension management: For older adults with orthostatic hypotension, practical advice includes rising slowly from sitting or lying, sitting on the edge of the bed for 30 seconds before standing, avoiding prolonged standing after meals (postprandial hypotension is particularly common in older adults), and maintaining adequate hydration. Compression stockings can help by reducing venous pooling in the legs. Medication review — particularly of antihypertensive combinations, alpha-blockers, and diuretics — is often the most effective intervention, with dose reduction or timing changes sometimes eliminating symptomatic hypotension without reducing blood pressure control overall.
Vitamin D and Falls Risk
Beyond its role in bone mineralisation, vitamin D has a direct effect on muscle function. Vitamin D receptors (VDR) are expressed in skeletal muscle, and adequate vitamin D levels support muscle strength, coordination, and reaction time — all relevant to balance and falls prevention. Systematic reviews of vitamin D supplementation in vitamin D-deficient older adults show a 20–30% reduction in falls rate, an effect that is independent of and additive to the bone density benefit of vitamin D supplementation. Our guide to vitamin D and bone health covers the evidence for supplementation doses, the muscle function mechanism, and the 25-OHD testing threshold in detail.
Year-round supplementation of 800–1,000 IU/day is recommended for adults over 65 — both for bone health and for falls prevention through muscle function support. This is one of the most cost-effective single interventions available in older adults at fracture risk, addressing both components of hip fracture risk simultaneously. Correcting vitamin D deficiency before winter — when synthesis stops entirely in the UK — is particularly important, as vitamin D levels naturally fall through the winter months and the muscle weakness and balance impairment from deficiency accumulates during this period when icy conditions also raise outdoor falls risk.
Frequently Asked Questions
What is the most effective exercise for fall prevention?
Combined balance and resistance training is the most evidence-supported exercise combination for falls prevention in older adults. Balance training specifically addresses the postural control and reactive balance responses needed to prevent a stumble from becoming a fall. Resistance training improves lower limb strength, which supports rapid stepping responses and recovery from balance perturbations. Tai chi has particularly strong evidence — multiple randomised trials show 19–29% reductions in falls rate — because it simultaneously trains balance, body awareness, and controlled movement patterns in a way that is accessible to frail older adults. A supervised class or physiotherapist-directed programme is more effective than self-directed exercise for falls prevention specifically, as supervision ensures correct technique and progressive challenge.
Can medications cause falls?
Yes — medications are one of the most significant and modifiable falls risk factors in older adults. Benzodiazepines and Z-drugs (zopiclone) impair alertness and balance; antidepressants (particularly SSRIs and tricyclics) independently increase falls risk through effects on movement coordination; antihypertensives can cause orthostatic hypotension — a transient drop in blood pressure on standing that causes dizziness; opioid analgesics impair alertness and reaction time; and sedating antihistamines (including many over-the-counter cold and allergy remedies) are potently sedating in older adults. Any older adult who has fallen should ask their GP to review whether their medications may be contributing to falls risk, and whether any can be reduced, stopped, or substituted with a less falls-promoting alternative.
How do I know if I’m at high risk of falling?
The most reliable indicator of future falls is past falls — if you have fallen twice or more in the past year, or once with a resulting injury, you are in the high-risk category. Other indicators include: difficulty rising from a chair without using your arms, unsteadiness when standing still or turning, taking 14 seconds or more to walk 10 steps and return (Timed Up and Go test), dizziness on standing, feeling unsteady when changing position, or taking 4 or more regular medications. The GP can assess falls risk formally using validated clinical tools (Timed Up and Go, the Berg Balance Scale, or FRAX for combined falls and fracture risk). A falls risk assessment is available through GP referral, particularly for those with two or more known risk factors.
Does vitamin D help prevent falls?
Yes — vitamin D has a direct effect on muscle function through vitamin D receptors (VDR) in skeletal muscle, and systematic reviews of supplementation in vitamin D-deficient older adults show 20–30% reductions in falls rate. This is a distinct mechanism from vitamin D’s effect on bone mineralisation — it is an independent falls prevention benefit. Adults over 65 who are vitamin D-deficient (25-OHD below 30–50 nmol/L) show the most marked improvement in muscle strength and balance with supplementation. Year-round supplementation of 800–1,000 IU/day for adults over 65 addresses both bone health and falls prevention simultaneously and is recommended by the UK Chief Medical Officers and NICE CG161.
What home modifications reduce falls risk?
The most impactful home modifications for falls prevention are: removing loose rugs and trip hazards from high-traffic areas; improving lighting, particularly on stairways and on the route from bedroom to bathroom; installing grab rails next to the toilet and in the shower or bath; and clearing trailing wires. Additional useful measures include: using a non-slip mat inside the bath or shower, organising storage to avoid reaching high or bending very low, ensuring the path from bed to bathroom is clear and lit at night, and wearing firm-soled non-slip footwear indoors rather than socks or loose slippers. An occupational therapist (OT) home assessment identifies the specific hazards in your home and recommends modifications — available on NHS referral through your GP.
Does having osteoporosis mean I should avoid exercise in case I fall?
No — avoiding exercise because of fear of falling is one of the least effective strategies for fall prevention and actively worsens both falls risk and bone health. Inactivity leads to muscle deconditioning and balance decline, which increases falls risk far more than the exercise itself. The goal is to choose exercises appropriate to the current fitness level and bone health status. For people with established osteoporosis, high-impact or explosive activities (jumping, sprinting) may not be appropriate, but walking, swimming, cycling, balance exercises, and progressive resistance training are all safe and beneficial. A physiotherapist experienced in osteoporosis management can advise on appropriate exercises, starting intensity, and safe progression. The natural bone health support guide covers exercise guidance for people with osteoporosis or low bone density.
Are falls prevention programmes available on the NHS?
Yes — NHS falls prevention services exist in most areas of England, typically through community physiotherapy, community rehabilitation teams, or dedicated falls prevention services. These usually offer: a falls risk assessment (gait, balance, strength, medication review, vision check); a structured exercise programme (balance and resistance training) delivered in groups or at home; home hazard assessment with occupational therapy input; and referral for vision or hearing review where indicated. Access is typically via GP referral, though some areas accept self-referral. If your GP has not proactively offered falls risk assessment and you have had a fall or are concerned about fall risk, you can ask for a referral specifically. The Royal Osteoporosis Society also provides information on finding local falls prevention programmes.
Summary
Falls prevention is an essential and evidence-based component of fracture prevention in older adults — not a secondary concern to be addressed only after bone density has been treated. Combined balance and resistance training reduces falls rates by 20–35% in older adults; medication review can eliminate or reduce major falls-risk drug contributors; home safety assessment addresses the environmental hazards responsible for half of all falls; and year-round vitamin D supplementation (800–1,000 IU/day) supports both bone mineralisation and the muscle function needed to maintain balance. Together with osteoporosis treatment for those above the NICE intervention threshold, these interventions address both sides of the hip fracture equation. Our guides to bone health after age 50, calcium and bone health, and magnesium and bone health cover the nutritional foundations of bone health that work alongside falls prevention.

I’m 68 and had two falls in the past year — one in the kitchen slipping on a wet floor and one outdoors on an uneven pavement. Neither caused a fracture, but my GP took both seriously and referred me for a falls risk assessment. I scored 14 seconds on the Timed Up and Go test, which she said indicated elevated falls risk. I was referred to a community falls prevention class — it runs weekly for 12 weeks and includes both balance exercises and light resistance work with resistance bands. I’ve also been going to a tai chi class separately, which my GP specifically mentioned as having good evidence for falls prevention. Three months into both programmes, my TUG time has come down to 11 seconds and I feel much more confident when I’m standing and moving. My GP also reviewed my medications — I was taking a benzodiazepine (temazepam) occasionally for sleep, and she advised stopping it as it was significantly increasing my falls risk. The article’s point about medication review as an underappreciated falls risk factor is something I wouldn’t have thought to raise with my GP — I had no idea temazepam increased fall risk.
Helen, your experience illustrates the clinical pathway working well — two falls triggering assessment, formal TUG testing identifying elevated risk, referral to a structured falls prevention programme, and medication review identifying temazepam as a modifiable contributor. The improvement in your TUG time from 14 to 11 seconds over three months reflects real gains in lower-limb strength and balance control, and is associated with a meaningful reduction in falls probability. Stopping temazepam will have contributed independently — benzodiazepines impair balance for hours after each dose and cause cumulative balance impairment with regular use. If sleep disruption was the reason for the temazepam, discussing non-pharmacological sleep approaches (sleep hygiene, CBT-I) with your GP is worthwhile, as these have better evidence for long-term insomnia than medication. Richard, your father’s case is an excellent example of how home hazard assessment identifies risks that are invisible to family members who are used to the space. The loose carpet at the top of the stairs is particularly high-risk — stair falls in older adults are among the most severe, as the person falls downward onto a hard surface. The combination of environmental modifications your father had made addresses most of the identifiable hazards, and the absence of falls in the following 8 months is consistent with the evidence that targeted home modification reduces falls in high-risk older adults. Ensuring his bone health is also addressed — FRAX and DEXA assessment, and osteoporosis treatment if indicated — would complete the dual approach to fracture prevention.
My father is 81 and lives alone. He had a fall last year that caused a bad bruise but no fracture. His GP referred him to the occupational therapist for a home assessment. The OT came to his house and identified several hazards I had honestly not thought about: a loose piece of carpet at the top of the stairs, no grab rail in his bathroom (he has a separate toilet from the bathroom), lighting in the hallway that was too dim, and he was wearing slipper-style moccasins with no heel support that he said felt comfortable but which the OT said provided essentially no ankle support or grip. We made all the changes — the GP practice arranged the grab rail installation through the council, we replaced the carpet section, bought a night light for the hallway, and I took my father to buy proper shoes with firm soles. In the 8 months since, he has not had a fall. I can’t be certain the modifications caused this, but the changes seemed logical. The article’s section on home hazard modification and the specific list of what to address matches exactly what our OT identified.
