International Consensus

World Health Organisation, 1996
“regular physical activity helps to preserve
independent living” and “postpone the
age associated declines in balance and
co-ordination that are major risk factors
for falls”

Surgeon General, USA, 1997
“Sedentariness is a major public health
issue”
We are all trippers….but
when do we become fallers?

Community Dwelling >65 years

Compared to non-fallers, fallers have
– ⇩ quadriceps and hamstring strength (NS)
– ⇩ ankle plantarflexion, dorsiflexion,
inversion and eversion strength
– ⇩ lower limb explosive power
– ⇧ asymmetry between limbs in power and
strength
Skelton, Kennedy, Rutherford Age Ageing 2002
Fear and avoidance of activity


Present in >50% of fallers & up to
40% non-fallers
Predicts
– decreases in physical and social
activity
– deterioration in physical
functioning
– higher risk of falling

Particularly common in people
who cannot get up from the floor
Lessons that last a lifetime
Sensory Input  Stability
Three main sources of input

Visual information

Vestibular information

Proprioceptive information
Falls Prevention Approaches

Individual Approach (high risk patients)
– Multi-factorial (ie. Falls Clinics) Unclear evidence
– Uni-factorial (ie. Exercise) Good evidence BUT…

Population based approach (targeting
communities)
– Emerging evidence, Relative reduction in fallrelated injuries 6 to 33%
– Most include increasing awareness and physical
activity, medication and home hazard reviews
Reviews of Exercise Evidence


2002 – Skelton & Beyer – Scand J Med Sports Sci 13:1-9

2004 - Chang et al. – Brit Med J 328: 680-687
– Multifactorial interventions reduce risk (RR 0.82)
– Exercise only interventions reduce risk (RR 0.86)
Know what to avoid…

Intervention: Brisk walking

Control: exercise of upper
arm

Falls risk (Brisk walking >
control)

Beware uneven pavements!

‘Pitfalls’ of interventions
that don’t work

Insufficient duration

Insufficient intensity

Insufficient tailoring or
specificity of training

Insufficient progression

Not enough time on
feet!
Balance Principles







Changes of direction, pace and level, head position,
weight (transference)
Sustained, controlled 3D moves
Progressively challenging tasks
to improve gaze stabilisation
Obstacle courses
Floor work: balances, crawling,
rolling, shuffling in seated position
Ball games
Breakdown all moves into 'steps' or stages

fall?
- Community Dwelling older people with mild deficits of
strength/balance, 2x/week for 15 weeks
Wolf et al. (1996)
– Cut trip and fall rate by half
- Frail older adults aged 70-97, 2 x/week
for 48 weeks
- no significant reduction in risk of falls
Wolf et al. J Am Geriat Soc 2003; 55: 1693-1701

home-based tailored progressive strength,
balance and gait training (3x p/w)
20-30% reduction in risk
Campbell J et al., BMJ, 1997
Then - Physiotherapist led nurse training
–For over 65’s – cost effective
–For over 80’s – saves money
Robertson C et al., BMJ, 2001
Then – with Visually Impaired Older People
- Not effective unless fully compliant

My residents are too frail?
Dose response curve

The lower the baseline level
of physical activity, the
greater the health benefit
associated with an increase
in physical activity. Exercise
can be adapted for any
medical condition
(Haskell 1994)

There would be no falls if
there was no rehabilitation!
(Oliver, D – 2006)

Simey, Skelton, Dinan, Land & Irwin (BMJ letter, 2001)
“I can walk upstairs now. I haven’t been able to walk upstairs for
four years. I do my exercises every day at home. I know it’s doing
me good”
Recommendations for Exercise
interventions to reduce the risk of
falls and injuries

Exercise works best within a multi-factorial
intervention programme
– Exercise should have components of balance, low impact
aerobic and strength
– To reduce fear, floorwork is recommended

To be effective the exercise must be specific,
regular (2-3 p/w), progressive, and exceed 15
weeks duration for those at risk of falls and 9
months for those who are already falling regularly
