Improving balance and
strength to prevent falls
All falls prevention guidelines recommend exercise
programmes to prevent falls in people aged 65 and
older. Does any regular physical activity reduce the
risk of falls and injuries or only particular types of
exercise programmes? Do we know the frequency
and intensity needed, and which subgroups of older
people should be targeted?
Topic 9 will address these questions, as health professionals want to offer
appropriate evidence-informed advice and referrals. The required reading
includes 1) a review of characteristics of effective falls prevention
exercise programmes and best practice recommendations and 2) advice
on communicating falls prevention messages to older people. Regular
physical activity by older people helps maintain cognitive function,
reduces cardiovascular risk, helps maintain ability to carry out activities of
daily living independently, improves mood and can improve self-esteem.
Hence, the required reading also includes 3) a factsheet on physical
activity for older people.
Exercises can improve strength,
balance, motor control and
cognition in older people
Many different risk factors contribute to falls and subsequent
injuries, but muscle weakness, poor balance and unsteady
gait underlie most falls.1 Older people with muscle
weakness, balance or gait deficits or mobility limitations are
3–5 times more likely to fall in any one year than their peers
without these functional impairments.2
Exercise is physical activity that is planned, structured,
repetitive and aimed at improvement or maintenance
of one or more components of physical fitness. Strength
training exercises increase muscle strength, core balance
and gait, even in frail older adults who are relatively weak.3
Mental skills become less efficient as we age, resulting in a
downturn in the quality of physical and mental performance.
However, strength and balance exercises have been shown
to improve executive function (cognitive processes) and
central and peripheral neurological control in older people.4
Not all types (or combination of
types) of exercises reduce falls. The
different types of exercises tested in
falls prevention trials are defined in a
taxonomy and include: gait, balance
and functional training; strength/
resistance; flexibility; 3D (eg, tai
chi); general physical activity; and
endurance.5
Which exercise programmes
prevent falls?
There is a strong evidence base for the effectiveness of certain exercise
programmes in reducing falls in older people.6, 7 The features of these
programmes differ in important ways such as the types of exercises
included, the delivery setting and the target group.
The most recent Cochrane review of falls prevention interventions in
older people living in the community included 59 randomised controlled
trials testing exercise programmes:6
• Multiple-component group exercise classes reduced falls by 29
percent (16 trials, 3622 participants). The classes were equally effective
in those selected, and not selected, for higher risk of falling.
• Multiple-component home-based exercise reduced falls by 32 percent
(seven trials, 951 participants). Three of these trials tested the Otago
Exercise Programme (OEP) in Dunedin and Auckland.8
• Tai chi classes reduced falls by 28 percent (five trials, 1563 participants).
Tai chi was more effective in the trials recruiting participants not at
high risk of falling.
Effective multiple-component

strengthening exercises against resistance.6
Walking can be included when considered
safe and appropriate, but high-risk
individuals should not be prescribed brisk walking programmes.7 Walking,
on its own, does not reduce falls but does benefit cardiovascular and
overall health.
Integrating balance and strengthening exercises into everyday activities
is effective in reducing falls.9 New programmes in the pilot stage for
preventing falls include step training using videogame technology.10
The Cochrane review of falls prevention interventions in care facilities
and hospitals concluded that exercise might reduce falls by 20 percent in
people in rest home level care, but increase falls by 29 percent in facilities
providing long-term hospital level care.11
All falls prevention guidelines, for example, from the US Preventive
Services Task Force, recommend exercise to prevent falls in older
people.12 The guidelines from the American Geriatrics Society and British
Geriatrics Society Panel on Falls Prevention in Older People recommend
that all older adults at risk of falling should be offered an exercise
programme incorporating balance, gait and strength training.3

Falls prevention exercise programmes
reduce injuries
Encouraging older people to take
part in exercise programmes
Systematic reviews and meta-analyses have shown that exercise
programmes designed to prevent falls in older adults reduce the injuries
caused by falls by 37 percent in community-living older people (17
trials, 4305 participants),13 and reduce the risk of sustaining a fall-related
fracture by 66 percent (six trials, 810
participants).6 These programmes also

care by 43 percent.
To ensure uptake and adherence, exercise programmes should be
acceptable to older people, and this needs to be considered at the
design stage. Barriers to participation include fatalism, fear of falling,
denial and underestimation of the risk of falling, poor self-efficacy, no
previous history of exercise, poor health and functional ability, low
health expectations and the stigma associated with programmes that
target older people.24
programmes
Offering choices both in terms of type of exercise and whether
delivered as an individual or a group-based activity makes it more likely
the older person will take part.25 Many older people enjoy the social
aspects of group classes, but others dislike joining groups or find it
difficult to attend. Home-based programmes should also be offered.
The home-based OEP reduced fall-related

injuries by 35 percent (four trials, 1016
fractures and
participants),8 and also reduced the
injuries.
risk of death in the study period by 55
percent (seven trials, 1503 participants).14
This programme was more effective in
participants aged ≥80 years. Injurious falls were reduced by 46 percent
more in this age group than in those aged 65 to 79.8
Many older people do not think they
are at risk of falling, so uptake should
be promoted by emphasising the
multiple positive benefits for health
and wellbeing, including maintaining
independence.25 A personal invitation
from a health professional is important,25
for example, with a Green Prescription.
In addition, meta-analyses suggest a relatively small, but possibly
important, effect of exercise on bone density in postmenopausal
women.15 Osteoporosis Australia recommends regular weight-bearing
exercise to help maintain bone density.16
Exercising can carry risks. Falls prevention exercise programmes have
generally been shown to be safe, but participants in one trial, where
heavy ankle cuff weights were used, had back or knee pain directly
attributable to the resistance exercises.17 As a general rule, exercises
should start light, and then gradually progress in difficulty and intensity.18
Exercise programmes delivered by experienced instructors or nurses
trained and closely supervised by a senior physiotherapist have been
shown to be effective. This approach ensures safe techniques, and
optimal benefit from each exercise.
The Accident Compensation Corporation (ACC) recommends several
approaches, including:
How often and for how long?
• ‘Steady As You Go’, an Otago-based peer-led programme, which
has proved successful in maintaining measures of strength and
balance, and continuation of exercise classes26
A meta-analysis investigating the characteristics of effective falls
prevention exercise programmes concluded that:7
• ‘Upright and Able’, a six-week exercise and education intervention
run in partnership with Nelson Bays PHO. This programme aims to
support people into community-based activities and targets the
older person at risk of a fall via a ‘single point of entry’ system.
• exercises should be undertaken for a total of at least two hours per
week on an ongoing basis
• the benefits of exercise are rapidly lost when exercise is ceased
• there were larger reductions in falls as a result of programmes
involving a higher ‘dose’ of exercise (≥50 hours over a six-month
period was categorised as ‘high’ and <50 hours as ‘low’ dose)
Exercising can be broken down into shorter segments during the day,
and can be incorporated into everyday activities.
Exercise programmes provide good
value for money
Falls prevention exercise programmes can reduce total health care costs,
particularly when targeted to older people at high risk of falling.19
We have a greater likelihood of success in meeting the challenges
posed by an ageing population when organisations collaborate in an
integrated, system-wide approach.
Providing the OEP to women ≥80 years reduced health care costs for
treating fall-related injuries and returned an estimated $1.85 for each $1
spent (185 percent return on investment).20 Tai chi returned an estimated
$1.60 for each $1 spent (160 percent return).21
Effective programmes can reduce fall-related hospital admissions in
community-living older people by 0.5–10.0 percent.22
A trial of the OEP in Auckland showed cost savings resulting from fewer
fall-related hospital admissions in participants aged ≥80 years.23
The US Centers for Disease Control and Prevention (CDC) has recently
echoed New Zealand’s earlier initiative18 by national roll-out of the OEP
and tai chi to reduce falls in targeted groups.

Acting on the evidence: key
messages?
There is strong evidence that certain exercise
programmes can reduce falls and even the most
serious injuries caused by falls, such as fractures, in
community-living older people.
Effective programmes, when implemented, reduce
health system costs by reducing fall-related hospital
admissions in community-living older people by up
to 10 percent, and provide a return on investment
of 160–185 percent.
Targeting falls prevention exercise programmes
• Generally falls prevention exercise programmes are equally effective
in the general community and those at higher risk for falls. However,
these programmes are likely to give better value for money in people
at higher risk, eg, those who report falling in the previous year.
• The message for targeting tai chi is that it seems more effective in
reducing falls in those not at high risk of falling.
• Falls prevention exercise programmes may reduce falls in agerelated residential care residents receiving rest home level care. But
in trials that included residents receiving hospital level care, exercise
programmes resulted in increased falls. Input from an appropriate
health professional is recommended.
Characteristics of effective programmes
• Falls prevention exercise programmes can be delivered in a group or
home-based setting.
• To prevent falls, the exercises must provide a moderate or high
challenge to balance, and lower body strength training exercises are
generally included.
• The exercise programme should be of sufficient ‘dose’ – at least
2 hours per week is recommended. This can include a mixture of
group and home-based exercise.
• Ongoing exercise is needed because the benefits are lost when
exercising stops.
• Walking offers general health benefits but individuals at high risk of
falling should not be prescribed brisk walking programmes.
Encouraging participation
REFERENCES continued
• The individual should receive a personal invitation from a health
professional and be offered a choice of programme types and
settings.
• As many older people reject the idea they are at risk of falling,
promotion of exercise programmes should emphasise the positive
benefits for health, wellbeing and independence.

This reading’s first best practice recommendation is that exercises must provide a moderate or high challenge to balance to be effective
in preventing falls. Exercises aimed at achieving this do not include:
Extending the base of support while standing. Movement of the centre of gravity while standing.
Reducing the need to use the arms for support while standing.
