International Standards for the Classification of Spinal Cord Injury Key Sensory Points (June 2008)

Vocabulary flashcards detailing the precise anatomical locations for the International Standards for the Classification of Spinal Cord Injury Key Sensory Points.

C2

Located at least $1\,cm$ lateral to the occipital protuberance at the base of the skull, or alternately, at least $3\,cm$ behind the ear.

C3

Located in the supraclavicular fossa, at the midclavicular line.

C4

Located over the acromioclavicular joint.

C5

Located on the lateral (radial) side of the antecubital fossa just proximal to the elbow.

C6

Located on the dorsal surface of the proximal phalanx of the thumb.

C7

Located on the dorsal surface of the proximal phalanx of the middle finger.

C8

Located on the dorsal surface of the proximal phalanx of the little finger.

T1

Located on the medial (ulnar) side of the antecubital fossa, just proximal to the medial epicondyle of the humerus.

T2

Located at the apex of the axilla.

T3

Located at the midclavicular line and the third intercostal space, found by palpating the anterior chest to locate the third rib and the corresponding intercostal space below it.

T4

Located at the midclavicular line and the fourth intercostal space, at the level of the nipples.

T5

Located at the midclavicular line and the fifth intercostal space, midway between the level of the nipples and the level of the xiphisternum.

T6

Located at the midclavicular line at the level of the xiphisternum.

T7

Located at the midclavicular line, $\frac{1}{4}$ the distance between the level of the xiphisternum and the level of the umbilicus.

T8

Located at the midclavicular line, $\frac{1}{2}$ the distance between the level of the xiphisternum and the level of the umbilicus.

T9

Located at the midclavicular line, $\frac{3}{4}$ of the distance between the level of the xiphisternum and the level of the umbilicus.

T10

Located at the midclavicular line at the level of the umbilicus.

T11

Located at the midclavicular line, midway between the level of the umbilicus and the inguinal ligament.

T12

Located at the midclavicular line, over the midpoint of the inguinal ligament.

L1

Located midway between the key sensory points for T12 and L2.

L2

Located on the anterior-medial thigh, at the midpoint of an imaginary line connecting the midpoint of the inguinal ligament and the medial femoral condyle.

L3

Located at the medial femoral condyle above the knee.

L4

Located over the medial malleolus.

L5

Located on the dorsum of the foot at the third metatarsal phalangeal joint.

S1

Located on the lateral aspect of the calcaneus.

S2

Located at the midpoint of the popliteal fossa.

S3

Located over the ischial tuberosity or infragluteal fold.

S4/5

Located in the perianal area, less than $1\,cm$ lateral to the mucocutaneous junction.
