Q

What causes migraine headaches? What is the hypothesis?

A

The cause is not clear. Primary headache‐ no real cause.

Hypothesis:

  • Certain parts of the brain hypersensitive‐ employing monoamines eg serotonin and noradrenalin
  • Reacts to stimuli such as emotion, sensory impulses, or any sudden change in the internal or external environment. (Hormonal or temp changes)
  • Interaction between the brain and the cranial blood vessels.
  • Treatment ‐aimed at constriction of dilated arteries to abort each headache as it comes or at the brain itself in an attempt to prevent the headaches

  6. Vagus (X) – Soft palate/uvula elevation‐ say AAGH
  7. Spinal accessory (XI) – SCM/Traps strength
  8. Hypoglossal (XII) – Tongue out
71
Q

What are 2 coordination test as VAD/VBI physical examination?

A
  1. Pro/supination
  2. Finger to nose
72
Q

What are 6 characteristics of VA physical (positional) testing?

A
  1. Tests the ability of the vertebrobasilar system to maintain hindbrain perfusion and adequacy of collateral supply
  2. NOT a test for dissection or safety with manual therapy
  3. All age groups may be susceptible
  4. Remember these are provocative tests
  5. Minimum reliance on physical testing
  6. History is main indication
  7. Controversial because does not tell you about risk of dissection and a negative test does not imply safety with manual therapy or manipulation
73
Q

What are 4 indications for physical testing?

A
  1. Any patient whose symptoms may indicate vertebrobasilar insufficiency
  2. All elderly patients with marked degenerative changes
  3. Pre manipulation (high velocity technique [HVT])
  4. Prior to any technique that may compromise the VA (eg end range positions)

NB: Only undertaken when VBI symptoms are vague or unclear

Intermittent dizziness or unsteadiness = suitable

74
Q

What are the 5 steps of positional testing? What is a positive response?

A
  1. Rotate head to one side and hold sustained not less than 10 secs unless symptoms provoked (sustain longer if indicated)
  2. Wait 10 secs on return from neutral (latency of symptoms possible)
  3. Repeat to other side, hold 10 secs
  4. Wait 10 secs in neutral
  5. Patient’s eyes should remain open – nystagmus
    • Gaze into patient’s eyes

Positive response: onset of dizziness, nystagmus, pre‐sycope

75
Q

What are 5 assessments in the cervical musculoskeletal examination?

A

Neck related dizziness (confirm dizziness coming from the neck)

  1. Cervical range of motion, kinematics*
  2. Flexion rotation test * (Upper cervical –> might be an issue)
  3. Manual examination* esp upper cervical, SNAG
  4. Cervical neuromotor control/ posture – neck, scapula,
  5. CCFT*
  6. Cervical and scapular muscle strength/ endurance

* Good discriminatory tests

76
Q

What are 6 assessments in the cervical sensorimotor examination?

A
  • VBI
  • Neck torsion vs en bloc*

Sensori‐motor

  1. Joint position sense (>4.5°)*
  2. Movement sense
  3. Balance
  4. Oculomotor
    1. Smooth pursuit neck torsion*
    2. Gaze stability
  5. Eye head co‐ordination
  6. Trunk head co‐ordination*
  7. +‐ Vestibular tests Hallpike Dix‐ BPPV, Others if requir*ed

Good discriminatory tests

77
Q

What is the cervical joint reposition error?

A

Target (between green or yellow region- Normal = 4.5 degrees) 90cm away from laser

Close eyes

Turn head and reposition head back to neutral

Can re-correct if not suitable

3 (consistent) attempts

78
Q

What are the 6 steps of the cervical joint reposition error?

A
  1. Sitting blindfolded/eyes closed
  2. Laser pointer/ torch
  3. Ensure standard distance away from target‐ 90 cm.
  4. Concentrate on the straight ahead position
  5. Move head slowly as far as comfortable and return back to the neutral straight ahead position as accurately as possible.
  6. Repositioning to neutral from left and right rotation, flexion and extension
79
Q

What is cervical JPE?

A

Laser method reliable and repeatable

80% healthy < 4.5°

80% neck pain > 4.5°

Convert cm to degrees (if needed)

7.1 cm at 90cm = 4.5 degrees Tan -1 distance/90cm = angle

80
Q

How ca cervical movement sense/accuracy be measured?

A

Track a pattern/path

  • Timed or how many times they come out of the lines
  • >9-10 errors OR >25 secs
81
Q

What is the smooth pursuit neck torsion test? What is a positive test?

A

Patient focuses on target- move target visual angle of 40 degrees crossing the midline left to right and back at a speed of 20 degrees per second

  • Compensation: quick catch up saccades (as cross midline)
  • 2 secs from one side to the other (eyes following smoothly) –> following a slow moving object
  • Keep head still in neutral
  • Keep head still and turn trunk –> repeat test (torsion position to R or L)
  • Neck should not influencing eyes
  • +ve test: Normal in neutral but worst in torsion position to R or L
82
Q

What is a SPNT?

A
  • Compare eye follow head neutral vs neck torsion
  • Altered ability to follow target when neck in torsion compared to neutral
  • Catch up saccades, blurred vision, increased difficulty, may be worse one side compared to the other – recently validated against EOG assessment
83
Q

What are 8 important physical examination for cervical differential diagnosis?

A
  1. Presentation/ History
  2. Cervical range of motion
  3. VBI testing, +- cranial nerves, co-ordination
  4. Neck torsion vs en bloc
  5. Musculoskeletal examination
    1. Manual examination
    2. Cervical neuromotor control/ posture
  6. Sensori-motor- clinical measures
    1. Joint position sense ±neck torsion/ movement sense
    2. Smooth pursuit neck torsion
    3. Trunk head coordination
    4. Oculomotor
    5. Balance and gait
  7. +- Vestibular tests Hallpike Dix- BPPV, head thrust, head shaking nystagmus, motion sensitivity
  8. +- Neurological exam
84
Q

What are cervicogenic dizziness subjective features and physical examination suggestive of CGD?

A
85
Q

What are 7 referrals if the diagnosis is not fitting cervical dizziness?

A
  1. medical review
  2. neurologist- vestibular migraine
  3. vestibular testing
  4. hearing tests
  5. further investigations
  6. vestibular physiotherapist
  7. behavioural optometrist

If mixed symptoms and benign - trial of management addressing cervical spine and sensorimotor control- similarities in approach

  • Eg. if they have vestibular symptoms, trial improving neck pain first as vestibular exercises/management can aggravate neck pain

Should see changes with improvements in neck and sensori-motor

86
Q

What is the differential diagnosis of patients with mild head injurt/concussion? What are 3 other considerations?

A
  • likely mixed forms

Cervical (M/S and sensorimotor) and vestibular physio in patients post sports concussion with persistent symptoms of dizziness, neck pain and or headache

  1. Primary cervical –> secondary vestibular
    • Stop moving neck and now starting to move again
  2. Primary vestibular –> secondary cervical
    • neck complaints associated with a primary vestibular problem
    • Stop moving neck and now starting to move again
  3. Cervical ‐ compensation for vestibular
    • implications elderly, falls prevention, vestibular clients, concussion
87
Q

What are 3 other consideratopms for cervical pain?

A
  1. Primary cervical –> secondary vestibular
    • Stop moving neck and now starting to move again
  2. Primary vestibular –> secondary cervical
    • neck complaints associated with a primary vestibular problem
    • Stop moving neck and now starting to move again
  3. Cervical ‐ compensation for vestibular implications elderly, falls prevention, vestibular clients, concussion
