Answer 2

Babinski, flexor withdrawal, crossed extension, traction, grasp, primary support reflex.

Question 3

toe extension and fanning

Answer 3

babinski reflex

Question 4

noxious stimulus to sole of foot → toe extension, dorsiflexion
and LE flexion

Answer 4

flexion withdrawal reflex

Question 5

noxious stimulus to sole of foot of LE fixed in extension->
opposite LE flexes, then adducts and extends

Answer 5

cross extension reflex

Question 6

pulling forearm (stretch stimulus) → UE flexion with head lag

Answer 6

traction reflex

pressure to palm of hand or foot (palmar surface) → flexion of fingers or
toes, respectively

Answer 7

grasp reflex

Question 8

weight-bearing (WB) through balls of feet; increased extensor
tone through LE and trunk
● Have patient stand and lean against a therapy ball on table to decrease mass extensor
response (promote trunk flexion)

Answer 8
