Reflexes

Question 1

Flexor Withdrawal

Answer 1

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

Primitive/spinal Reflex

Question 2

Crossed extension Reflex

Answer 2

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

Primitive spinal reflex

Question 3

Traction

Answer 3

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

Primitive/Spinal Reflex

Question 4

Grasp reflex

Answer 4

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

Question 5

Asymmetrical Tonic Neck Reflex

Answer 5

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

Tonic/brainstem reflex

Question 6

Symmetric Tonic Neck Reflex

Answer 6

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

Question 7

Positive Supporting Reflex

Answer 7

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

Tonic/brainstem reflex

Question 8

Associated reactions

Answer 8

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

Question 9

C5-C6, emphasis on C5

Answer 9

Biceps deep tendon reflex

Question 10

C7-C8

Answer 10

Triceps Deep Tendon reflex

Question 11

C5-C6, emphasis on C^

Answer 11

Brachioradialis DTR

Question 12

L5-S3

Answer 12

Hamstring DTR

Question 13

L2-L4

Answer 13

Quadriceps DTR

Question 14

S1-2

Answer 14

Achilles DTR

Question 15

Plantar reflex

Answer 15

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

Question 16

Positive babinski Response

Answer 16

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

Question 17

Abdominal reflexes

Answer 17

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

Question 18

Crenasteruc reFKEX

Answer 18

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