Q

reasons why we do a scan examination (5)

A
  1. To ensure patient presentations are within the scope of physical therapy practice. (rule out red flags or referrals)
  2. The scan helps to streamline your detailed assessment. (find the joints that require your attention and rule out others)
  3. Briefly consider the presence of regional interdependence or victims and culprits within the quadrant. (pain at te elbow but shoulder if the problem)
  4. The scan alone can help identify common orthopedic lesions that present acute or sub-acute. (“flared-up”, patient can have multiple pathologies at once)
  5. To detect gross loss of function, ROM, strength, and movement control. (patient may not outline this is Subjective history)

Q

Clinical decision making involves two
modes of thinking, what are they?

A
  1. intuitive thinking: quick, usually effective, characterized by rules of thumb, clinical patterns and shortcuts. (EXPERIENCED CLINICIANS)
    - Can lead to errors (cognitive bias).
    - Good for when diagnosis is straight forward.
  2. slower, analytical, and more resource intensive. (NEW GRADS)
    - Good for when the patient’s presentation is unusual.

Q

what is regional interdependence?

A

impairments in seemingly unrelated or remote anatomical regions can contribute to a patient’s primary concern. (biomechanics but could be influenced by neurophysiological mechanisms)
- can include multiple body systems

26
Q

what is a myotome?

A

muscles that are supplied by a single segmental level (BUT most muscles are multi-segmentally innervated) -> motor neuron innervation

27
Q

When trying to localize segment of lesion, the best option is to test the strength of:

A

specific key muscles which are most representative of a given segment.

28
Q

how do you test a myotome? explain it.

A

a make test: isometric contraction held for 5 seconds.
- may do repitions if weakness suspected
- test one muscle per myotome

29
Q

how can deep tendon reflex help us?

A
  • Give some information to help localize lesion.
30
Q

hypertonic reflexes suggests what neuron involment

A

UMN, inhibition is lost

31
Q

what is the grading of deep tendon reflexed?

A
32
Q

what is a dermatome?

A

the area of sensation mapped out by a single nerve root distribution

33
Q

why do we use a wrap around technique when testing sensation?

A

Dermatomes overlap and are somewhat variable from person to person.
- If an area of hypoaesthesisa, hyperasthesia, dysaesthesia is found, farther testing needs to be completed in detail

34
Q

dermatomes of the upper limb

A
35
Q

dermatomes of the lower quadrant

A
36
Q

what is a neurodynamic test

A

Test the ability of the nervous system and its supporting connective tissue to passively slide or glide in response to trunk or limb movement

37
Q

what is dura pain?

A

Pain produced when dura is involved is multisegmental with no defined boundaries
* Pain tends to be “somatic”, like an ache
* Does not produce paresthesia

38
Q

what kind of pain does problem with ventral root produce?

A

segmental pain, or radicular pain, which is pain felt along that nerve root’s dermatome

39
Q

what kind of pain does problem with dorsal root produce?

A

segmental paresthesia or hypoaesthesias along that nerve root’s dermatome
(usually distal part)

40
Q

what are examples of neurodynamic tests (5)

A
  • Passive neck flexion (Upper Q)
  • Upper limb neurodynamic tests (Upper Q)
  • Slump test (Both)
  • SLR (Lower Q)
  • Prone knee bend (Lower Q)
41
Q

examples of UMN testing

A
  • babinski response (lower)
  • hoffmans sign (upper)
42
Q

things you look for in observation of upper quadrant scan

A

Head position, scar(s), muscle atrophy,
scapular position, deformities

43
Q

what is overpressure

A

when a patient performs a movement and then clinician applies pressure at end range of movement.

44
Q

myotomes of the upper extremity and their associated movements

A
45
Q

what does the slump test test

A
  • Tests extensibility of dura
46
Q

what does a slump test look like?

A
  • Patient seated at side of bed with feet unsupported and hands clasped behind
    back.
  • ask patient to slump but down allow pelvis to rotate (slump at stomach)
  • chin to chest and hold
  • kick out foot and hold leg as close to straight as possible
47
Q

when do you stop the slump test?

A

whenever stretch or pain is produced

48
Q

what is an example of winding up the nervous system in the slump test

A

Maintain leg position but have patient
look up a little.
* Check if more knee extension is now
available (to onset of symptoms

49
Q

what is a positive slump test?

A

produces their typical symptoms. therefore dura involved

50
Q

describe passive neck flexion for both upper and lower cervical flexion

A
  • Patient lies supine with no pillow
  • arms and legs extended
  • tuck chin
  • Therapist gently maintains tuck and cradles the head around the occiput, then gently lifts head with patient relaxing (combined upper and lower flexion).
51
Q

what does ULTT-A stand for?

A

upper limb tension test-A

52
Q

describe the anatomical positioning of ULTT-A

A

Scapular elevation is prevented as the arm is sequentially brought into abduction, forearm supination, wrist and finger extension, shoulder external
rotation, and elbow extension.

53
Q

describe the clinical prediction rule and why we use multiple tests during a scan?

A

getting a positive score on 4 neurodynamics test greatly increases the likelihood of proper prediction/diagnosis when compared to getting a positive score on 3 tests. Therefore, the more tests we do the more confident we can be in what is creating the symptoms.

54
Q

what is the final item you want to do in an upper or lower body scan?

A

palpation

55
Q

what are you testing for during palpation?

A

Check for pain provocation
Also check to see how willing the segment is to move

56
Q

why types of things are you observing/looking for in a lower body scan?

A
  • Postural Type
  • Gross deformities
  • Scoliosis
  • Gait
57
Q

what action can you perform to test different myotomes of the lower extremities?

A
58
Q

what are 3 tests we can do in the lower quadrant to test neurodynamics?

A
  • slump
  • straight leg raises
  • prone knee bend
59
Q

What is the straight leg raise test

A

Nerve root tension test where patient lies supine (no pillow with both legs straight. Slow hip flexion with knee extension is performed to point of pain or tension in either posterior thigh, knee or calf extending to foot.

60
Q

How many degrees of hip flexion is considered normal during straight leg raise test

A

70

61
Q

T or F: Straight leg raise tests can be sensitized by adding additional movements like ankle dorsiflexion, eversion or hip abduction to wind up tissues

A

T

62
Q

Describe the prone knee bend test

A

Patient lies prone and you slow, gentle passive knee flexion is performed while other hand monitors lumbar spine to see if their typical leg complaints show up

63
Q

What is the prone knee bend test also called

A

Femoral nerve stretch

64
Q

Where do you palpate lower back

A

Apply gentle pressure near lumber spine and level of pain
