Q

Median N palpation

A
  • mid humerus: abd shoulder to 90, med n is just under biceps on ant-med aspect of arm
  • elbow: med to biceps tendon in cubital fossa
  • carpal tunnel: very deep so we use indirect palpation –> slowly apply pressure over tunnel

Q

Radial N Palpation

A
  • upper arm: 90 shoulder abd and ER, just distal to axilla
  • distal humerus: 3-4 finger widths distal to deltoid tuberosity - runs oblique
  • lateral forearm: just proximal to styloid process - 3-4 finger width prox along radial aspect of radius
  • anatomical snuffbox: come up from dorsal aspect and push dorso radially

Q

Ulnar N palpation

A
  • mid hum: 90 abd, 90 ER - post to biceps and med n on medial hum
  • elbow: cubital tunnel - prox and distal to tunnel
  • Guyon canal - start at pisiform, move still and toward little finger - press Doral and try rolling over - just med to hamate

Q

sciatic n palpation - prone

A
  • 1/2 way between isch tub and greater troch - nerve in bottom 1/3 of that line - deep
  • wont typically feel nerve but may illicit symptoms

Q

laterality testing

A

a) Form of motor imagery – pt. imagines left hand in orientation of left had stimuli

b) Implicit motor imagery – patient is unaware of imagined movement

c) Activates cortical (prefrontal) network involved in limb representation and preparation for movement

d) Does NOT activate motor cortices

Q

spine laterality testing

A

use pictures of R/L rotation

17
Q

How to do 2PD Testing

A

Start below threshold and increase 2 mm
- enough pressure to blanch the skin
- 3-5 ascending/descending trials at the same region

18
Q

PPT technique

A

the flat, circular rubber tip of the plunger is placed perpendicular to the subject’s skin and pressure steadily applied until the subject reports that the pain threshold (or pain tolerance) is perceived

19
Q

how much pressure for PPT

A
  • pressure is applied at a uniform rate of 1 kg/sec
20
Q

normative data PPT

A

a) abnormal when the pressure pain threshold of a certain site was at least 2 kg/cm2 lower than opposite
site, was lower than the normal value, or was not >3 kg/cm2.

b) PPT of less than 29.42 N/cm2 should be considered as a clinically relevant indicator of pathological hypersensitivity
