Q

What is an incomplete SCI?

A

In an incomplete SCI, some function remains below the primary level of the injury. A person with an incomplete injury may be able to move one arm or a leg more than the other, or may have more functioning on one side of the body than the other.

Q

Why is pain and temperature sensations lost on the opposite side of the body?

A

because these pathways cross to the opposite side shortly after they enter the spinal cord.

A

Diaphragm
Deltoid, biceps
Triceps, extensors of the wrist
Interossei, abductor of 5th digit
Quadriceps
Long extensor of great toe
Plantar flexors, gastrocnemius

19
Q

A

Clavicle
5th finger
Nipples
Umbilicus
Inguinal Ligament
Anterior surface of thigh
Great toe
Lateral aspect of foot
Perineum

20
Q

What are the three types of stroke?

A

Haemorrhagic stroke
Ischemic stroke
Transient Ischaemic Attack (TIA)

21
Q

What is a stroke?

A

Rapid death of brain tissue due to disturbance of blood supply

22
Q

What is a haemorrhagic stroke? What percentage of stoke patients have this type?

A

A blood vessel in the brain ruptures and bleeds, causing brain cell death

10-15%

23
Q

What is an Ischemic stroke? What percentage of stroke patients suffer this type?

A

A blood clot forms in a main artery, blocking and reducing blood supply, causing brain-cell death.

80-90%

24
Q

What is a TIA?

A

TIA)- mini stroke that resolves within 24hrs, early warning of full stroke risk (15% of strokes preceded by TIA).

25
Q

How does cerebral palsy occur?

A

Oxygen deprivation at birth

26
Q

What will the effect of stroke depend on?

A

What blood vessels are involved

27
Q

What can Brain Stem Strokes lead to?

A

‘Locked in syndrome’

28
Q

What can a spinal cord stroke lead to?

A

Effective spinal cord injury

29
Q

What will you see in a neurological examination

A

-Paralysis on one side of the body (face, arms, legs)

– Vision problems
– Speech problems
– Memory loss

30
Q

What is fast?

A

Face
Arms
Speech
Time

31
Q

What is the treatment time after the ischemic stroke?

A

Ideally within 4.5hrs of event
– If ischemic can use plasminogen activators (tPA) to break up clots. tPA is
administered by injection into vein.
– Aspirin (or anticoagulants) also used to help prevent clotting

32
Q

What is needed for a haemorrhagic stroke?

A

Surgical intervention may be needed.
– Aneurysm Clipping
• Clipping blocks of the blood vessel with the aneurysm to prevent reoccurrence of the bleed.
• Coil embolization- a coil is placed into the aneurysm site via a catheter and will cause a blood clot to form. This will block blood flow through the aneurysm and prevent it from bursting again

33
Q

Give 9 examples of long term effects of stroke

A
  1. Paralysis (face, arm, leg or entire side of body) (hemiplegia)
  2. Dysphagia (difficulty swallowing)
  3. Ataxia (poorly coordinated movements, cerebellar involvement)
  4. Spasticity and contractures
  5. Paraesthesia (loss of sensation)
  6. Pain
  7. Aphasia (difficulty in understanding language)
  8. Cognitive impairment and memory problems
  9. Mood disorders
34
Q

What are movement disorders?

A

A group of conditions/diseases/syndromes that affect the nervous system and cause abnormal voluntary and involuntary movements. They also can result in slow or reduced movements.

35
Q

What are there many different forms of?

A

Movement disorders

36
Q

Give an example of a movement disorder?

A

Parkinson’s disease

37
Q

How does Parkinson’s disease occur?

A

Loss of dopamine from substantial Nigra

38
Q

What are the 4 cardinal signs of PD?

A
  1. Rest Tremor
  2. Bradykinesia (slowness of movement)
  3. Rigidity
  4. Postural Instability
39
Q

How is Parkinson’s disease diagnosed?

A

Diagnosis normally is made if the patient presents with 3 of the above and if the symptoms are suppressed by L-DOPA treatment.
Diagnosis can be further confirmed by positron emission tomography (PET) or single-photon emission computed tomography (SPECT) scan showing reduced dopamine uptake.

40
Q

What does deep brain stimulation in Parkinson’s disease target?

A

subthalamic nucleus with electrical stimulation via implanted electrodes

41
Q

What are the types of pathological tremor?

A

Rest Tremor (e.g. Parkinson’s Disease)
– Action Tremor
• Postural Tremor (arms outreached, eg Essential Tremor)
• Kinetic Tremor
– Non-goal directed kinetic tremor (flex/ext)
– Intention Tremor (goal directed tremor, finger to
finger)

42
Q

What is functional electric stimulation (FES)?

A

a treatment that applies small electrical charges to the leg to improve mobility in people who have difficulties with walking arising from damage in their brain or spinal cord. In MS it is mostly used as a treatment for foot drop.

43
Q

What is transcranial magnetic stimulation?

A

a non-invasive procedure that uses magnetic fields to stimulate nerve cells in the brain
