27
Basal ganglia role in balance
Timing cues for automatic movement | Postural reflexes
28
Cerebellum role in balance
Fine tunes postural adjustments Makes ‘coarse adjustment’ for slow voluntary, movement Coordinates rapid, ballistic movements
29
Reflexes that happen in the spinal cord
Stretch reflex | Crossed extensor reflex
30
Reflexes that happen in the brain stem
Maintenance of postural muscle tone | Righting reflexes
31
Aging effect on vision
Reduced acuity Reduced contrast sensitivity Reduced dark adaptation
32
Aging effect on sensation
Reduced proprioception | Reduced touch sensitivity in the foot
33
Aging effect on brain
Fewer neurones Fewer nerve fibres Slower reaction times Impaired integration of sensory info
34
Aging effect on muscle
Reduced muscle mass Reduced muscle strength Slower contraction
35
Outcomes following a fall
Increased mortality, long term disability and earlier entry to residential care Fragility fractures cost UK £4.4 billion over year
36
Who is targeted when giving out home assessments
``` High risk fallers Fallen before in <1yr Fall with injury Cognitive impairment Visual impairment Gait or balance impairment Fear of falling Leaving a rehab setting particularly post neck fracture NOF ```
37
Purpose of home assessments
Identify home hazards and recommend or arrange modifications Assess and modify performance and function Identify and agree strategies to reduce falls risk Education and information giving
38
What should older people who have received treatment in hospital following a fall be allowed
A home hazard assessment and safety intervention/ medications
39
Local pathways for accessing home assessment - primary care
Supported care to home incl OT home assessment Community OT Falls vehicle: paramedic and OT
40
Local pathways for accessing home assessment - secondary care
``` A+E OPED OPAC wards OPAS ```
41
OPED
Older peoples emergency department, undergoes comprehensive geriatric assessment
42
OPAC
Older peoples assessment centre (nurse led discharge centre)
43
OPAS
Older peoples assessment service (consultant-led outpatient service)
44
How much of our population is 60+
Over a 1/5
45
What are the 3 broad groups older people belong to
Entering old age Transitional phase – between a healthy active life and frailty Frail older people
46
Proportion of NHS budget spent on 60+
~40%
47
Proportion of social service budget spent on 60+
~50%
48
Proportion of general and acute beds used by those 65+
Almost 2/3
49
NHS and social care action plan
``` Improve standards of care Extend access to services Ensure fairer funding of long-term care Develop services which support independence Help older people to stay healthy ```
50
Frailty
Not an illness, but a syndrome that combines the effects of natural ageing with the outcomes of multiple long-term conditions, a loss of fitness and reserves
51
Medical definition of frailty
Older people with 1/1+ chronic, long-term condition e.g heart disease, COPD Older people who may not have a spp, diagnosed condition, but who may nevertheless require support from care services to live independently and Older people who are on the threshold of either of these two groups
52
Frailty syndromes
``` Deliriium Falls immobility - sudden change Continence problems Med management challenges ```
53
MDT approach for older pt's and falls
``` GP & nursing team Family Social care OT PT SLT ```
54
MDT community services aim
Prevent Hosp admission - crisi management
55
Aim of rapid response teams
To prevent admission and set up immediate short term intervention plan
56
Consequences of hosp admission
Older people are at risk of deterioration | If admitted for inpatient hosp care, the oldest have readmission rates and highest rate of long-term care use after d/c
57
Why are older people at risk of deterioration when admitted to hosp
Factors affecting this are the environment, care delivery and risks
58
OT job role
identifies occupational performance issues & implement plans to facilitate independece
59
SLT job role
Anticipates and responds to the needs of individuals who experience speech, language, communication or swallowing difficulties
60
Activity limitation due to recurrent falls (+ subsequent injuries)
Not able to go out --> loss of social network and relationships
61
Activity limitation due to Parkinson's
Difficult swallowing food and gripping cutlery --> no longer feels able to go ut for a meal
62
Age discrimination statistics
Experienced by 36.8% of people aged 65/ 65+ 53% believe treated as a child 68% believe politicians see them as a low priority
63
Social aspect of aging
Physical and mental decline are not inevitable in later life. As people grow older, they work to maintain their own sense of personal identity. People may experience the self as ‘younger’ than the body. Dementia and Alzheimer's disease do not necessarily mean loss of self
64
Types of delirium
Hyperactive, hypoactive or mixed with features of both
65
Hyperactive delierium
pt may have heightened arousal, agitation, aggression, restlessness
66
Hypoactive delirium
presents with a withdrawn patient, that is quiet, with reduced oral intake decreased responsiveness and slowed motor skills. More difficult to spot in a pt
67
Priorities of managing a pt with confusion
Maintaining patient safety by removing from potential harm Identifying and treating precipitants Managing symptoms
68
Importance of recognising delirium
Pts who develop delirium have worse outcomes Longer periods of hospital stay Increased risk of falls Increased risk of pressure sores Early recognition reduces these risks. New confusion is now included in the NEWS early warning score
69
Postural hypotension
A drop in systolic BP of greater than 20 mm Hg or a drop in diastolic BP of greater than 10 mm Hg shortly after standing.
70
Hx for falls
``` Previous falls or fractures Hx of gait or balance problems Medications Detail SH incl mookilty aids, hazards home Hx of drug and alcohol DO they drive - relevant if syncope ```
71
Medications that can cause falls
``` Antihypertensives Anticholinergics Antipsychotics Sedatives Opiates Antidepressants, Hypoglycaemics ```
72
Examination for fallen pt
``` Gait assemsnt Cardiovascular assessment Neurological examination Examination feet and joints Check vision Check cognition ```
73
Cardiovascular assessment for fallen pt
Pulse rate and rhythm, lying and standing blood pressure (BP), and presence of cardiac murmurs.
74
What are we looking for in a neurological examination for a fallen pt
Evidence of stroke, Parkinson's disease, peripheral neuropathy, foot drop, cerebellar signs, and proprioception problems.
75
Ix fir a fallen person
Bloods ECG – arrythmia or cardiac disease Lying and standing bp Tilt table test for syncope
76
Blood for a fallen person

77
Management after admission w/ a fall
Treat underlying medical causes and delirium Treat postural hypotension Medication review aiming for deprescribing Ensure appropriate footwear Gait and balance training by a pt Environmental assessment by an OT Consider use of pendant alarms, bed or chair sensors
78

Corticosteroid used for treating postural hypotension
79
Fludrocortisone dosage
100mg – 400mg ODS
80
