WHY?
Objectives
To gain an understanding of the different strategies to
limit falls risk in older people
To provide evidence based interventions that can be
applied in clinical settings
Goals
Review physical changes that occur that increase falls
risk among older people
Examine interventions that can be put in place to
reduce falls risk
What is the evidence for falls in older people?
Falls third commonest cause of injury related death.
1/3 falls need medical care
5% of falls – serious injury
Hip fracture
5% residential care
1% in community dwelling older people
QOL, functional status, care needs, disability
Injury is the tip of the iceberg of morbidity from falls
Costs – 106‐400m/year

Physical changes with age
Reaction time
Coordination of balance
Coordination of supportive muscle function
Dependence on visual acuity and peripheral sensing
Dual task performance
General wellbeing (physical, psychological...)
Impact on functioning
Slowed reaction time
Greater difference in choice reaction time
Loss of muscle strength
Decreased by 1/3 from a peak at 25 years to age 65
Small decrease in gait comfort speed
Greater difficulty rising from a chair / bed
Altered postural control

–
pragmatic clinical advice
Hot falls: acute medical problem
Infection
Cardiovascular event
Cold falls: less‐acute
multifactorial
Post hot fall: health professional a detective
Is it new or old
Are they acutely unwell
Intrinsic causes of falls, Stroke, MI, other CV, infection,
constipation, dehydration
Are they poisoned
Assume medication as a cause until proven otherwise,
new mediation, interaction, adverse reaction
Is there an injury
Cold fall ‐ assessment
Opportunistic or after a fall
Consider risk factors in hx, fear of falling
Parkinsons, stroke, mobility, functional status, medications
Psychotropics esp hypnotics, cardiovascular
Physical exam, esp cardiovasc, neurological, gait and balance
Feasible intervention based on risk factors

Group based LLimb strengthening, balance and reaction time, falls reduced 40%
(Lord JAGS 2003)
Tai Chi, 15 wks, fear & mult falls reduced 47% (Wolf, JAGS 1996)

Residential Aged Care
Other factors increasing falls risk and influencing
functional changes and decreased physical activity in residents include:
underlying physical and cognitive function
health status
motivation
cultural expectations
environmental factors
coexisting disease states
fear of falling
( Cameron, Kurle, Cumming, & Quine, 2000 ; Crews, 2005 )
Who should encourage physical activity and so reduce falls risk in RAC?
