Flashcards in Reflexes Deck (18):
1

Flexor Withdrawal

Noxious stimulus to sole of foot produces toe extension, dorsiflexion of the foot and flexion of the entire LE

Primitive/spinal Reflex

2

Crossed extension Reflex

Noxious stimulus to sole of foot produces flexion of stimulated leg then extension with adduction of opposite leg.

Primitive spinal reflex

3

Traction

Stretch stimulus from grasping the forearm and pulling produces total flexion response of the UE

Primitive/Spinal Reflex

4

Grasp reflex

Maintained pressure to palm of hand or ball of foot produces maintained flexion of fingers or toes

5

Asymmetrical Tonic Neck Reflex

Rotation of the head to one side produces flexion of the skull limb and extension of the jaw limbs

Tonic/brainstem reflex

6

Symmetric Tonic Neck Reflex

Flexion of the head produces flexion of the UE's with extension of the LE's
Extension of the head produces extension of the UE's and flexion of the LE's

Tonic Brainstem reflex

7

Positive Supporting Reflex

Contact to the ball of the foot in standing position produces rigid extension (co-contraction) of the LE's

Tonic/brainstem reflex

8

Associated reactions

Strong voluntary movement in one body segment produces involuntary movement in another resting extremity.

9

C5-C6, emphasis on C5

Biceps deep tendon reflex

10

C7-C8

Triceps Deep Tendon reflex

11

C5-C6, emphasis on C^

Brachioradialis DTR

12

L5-S3

Hamstring DTR

13

L2-L4

Quadriceps DTR

14

S1-2

Achilles DTR

15

Plantar reflex

S1-S2 Tibial nerve
Stroking of the lateral sole of the foot from calcaneus to base of 5th metatarsal and medially across metatarsal heads produces plantar flexion of the toes in neurologically intact individuals

16

Positive babinski Response

Stroking in lateral sole of foot from calcaneus to base of fifth metatarsal and medially across metatarsal heads produces dorsiflexion of the great toe and fanning of the four lesser toes.
Seen in corticospinal lesions

17

Abdominal reflexes

Lateral to medial scratching of the skin (towards umbilicus) in each of the four quadrants produces deviations of the umbilicus toward the stimulus
Loss of reflex is sign of corticospinal lesion

18

Crenasteruc reFKEX

Stroking skin of the proximal and medial thigh produces elevation of the testicles
Absent in SCI and corticospinal lesions
