What is Geriatric Medicine ?

• .that branch of general medicine concerned with
  the
• clinical (physical mental)
• rehabilitative
• social
• preventive
• aspects of illness and health in the elderly

• T 36.7 O C, P 96 / min., R 20 / min.
• BP 120 / 60 mmHg.(sitting), 90 / 40
  mmHg.(standing).
• conscious but mute, on wheelchair, sthenic built,
  not pale, not icteric, JVP 1 cm., normal tone in
  all extremities, motor power grade IV for all
  extremities without focal neurological weakness

• All other physical examinations were
  unremarkable.

Physical Examination of Fall

• Complete and thorough examination
• - Degree of injury
• - Physiologic aging changes
• - Precipitating factors
• Some special tests
• - Get-up-and-go test
• - Performance-oriented mobility assessment
• - Rombergs sign with slight push rollator

10
Innovation in Get-up-and-go-test

• Timed get-up-and-go test
• sit, stand from arm-chair, walk 3 meters,
  turn, walk back to chair and sit down
• one trial run before timed test
• Categorical scale scoring
• lt 10 sec. freely mobile
• lt 20 sec. mostly independent
• 20-29 sec. variable mobility
• gt 29 sec. impaired mobility

11
Abnormal Gait in Old Age

• Frontal lobe gait (frontal ataxia or apraxia)

  flexed posture, small shuffling, hesitant step
• Magnetic gait, slipping clutch syndrome
• DDx Alzheimers disease, Vascular dementia, NPH

12
Abnormal Gait in Old Age

• Sensory Ataxic Gait
• Wide-based, foot stamping walk with high stepping
  due to loss of proprioceptive input, constantly
  observe the foot position
• Rombergs sign positive
• DDx Thiamin deficiency, Subacute combined
  degeneration of spinal cord, spinal cord
  compression, diabetic neuropathy

13
Cerebellar Ataxic Gait

• Wide-based, small irregular unsteady, staggering,
  sudden lurching to either side, forward or
  backward like being drunk

  visual
• DDx vestibular damage, stroke, chronic
  alcoholism, progressive supranuclear palsy,
  thiamin deficiency, hypothyroidism, drug
  intoxication

14
Spastic Gait

  plantar-flexed foot
• - Affected arm flexed elbow across abdomen,
  impaired
• arm swing, toe scraping or dragging across
  the floor
• - Visual neglect or hemianopia
• Paralegia (scissoring gait)
• - Cervical spondylitic myolopathy, Subacute
  combined
• degeneration of spinal cord, chronic cord
  compression,
• lacunar infarcts

15
Steppage gait

• Lifting the feet hight off the ground due to foot
  drop (pretibial, peroneal muscle weakness)
• DDx peripheral neuropathy, prolonged pressure,
  DM, alcoholism, B12 deficiency
• Festinating Gait
• Symmetric rapid shuffling of feet, stooped
  posture, flexed hip and knee
• Centre of gravity shifted forward
• DDx Parkinsonism, vascular dementia,
  hydrocephalus

16
Podalgic Gait

• Foot disorders corns, calluses, in-growing toe
  nails, bunion, atrophy of plantar pads
• Loose or tight-fitting footwear
• Dementia-related gait
• Slow speed, decreased step length, increased
  double-support time, increased step-to-step
  variability, increased postural sway
• Marked flexed posture
• Gait apraxia but must exclude frontal lobe
  lesion, NPH

17
Wadding Gait

• Duck or penguins walk
• Limb girdle muscle weakness, lateral trunk
  movement away from the foot as it lifts
• Difficulty climbing stair, getting up from
  low-seated chair
• DDx hypo/hyperthyroidism, polymyositis,
  osteomalacia, proximal myopathy

18
Multisensory Deficit Gait

• Concurrent visual and proprioceptive impairment,
  vestibular dysfunction
• Dizzy, lightheadedness when walk or turn around,
  using canes or touch walls or other furnishings
• DM
• Antalgic Gonalgic Gait
• Painful hip and knee conditions, reluctant to
  place weight on the affected limb, avoid heel
  strike and push-off, less knee extension during
  gait

• 1043 elderly subjects living in the urban area
  around Siriraj Hospital Medical School, Bangkok.
• 585 -- study group vs. 458 -- control group.
• A leaflet containing information on important
  risk factors of fall within their community. In
  addition, this particular group was allowed free
  access to the geriatric clinic at Siriraj
  Hospital if there was any health problem.
• Followed up every 2 months for 1 year

Causes of Acute Reversible Forms of Urinary
Incontinence

• D Delirium

• Alcohol Polyuria, Sedation, Delirium

32
Persistent Incontinence

• 1. Stress Leakage of urine (small amounts)
  with increases in intraabdominal pressure
• 2. Urge Leakage of urine (larger volume) due
  to inability to delay voiding after sensation of
  fullness
• 3. Overflow Leakage of urine (small amounts)
  from urinary retention
• 4. Functional Leakage of urine (larger volume)
  with inability to toilet due to impaired
  cognition, physical function, Psychological,
  environmental barriers

33
Causes of Persistent Incontinence

• 1. Stress Pelvic floor, Bladder outlet or
  Urethral sphincter weakness
• 2. Urge Overactive bladder, Detrusor
  hyperreflexia due to Cystitis, Urethritis, Tumor,
  Stone, Diverticuli,Stroke, Dementia,
  Parkinsonism, Suprasacral spinal cord injury
• 3. Overflow Obstruction by Prostate,
  Stricture, Cystocele
