A

rolling from supineprone

24
Q

Tonic labyrinthine reflex present

A

0-6 months

25
Q

Asymmetrical tonic neck reflex

A

rotation of head results in flexion of face side extremities and extension of skull side extremities. Stronger in LEs.

26

may result in scoliosis or hip dislocation and interfere with grasping and hand mouth activities

27
Q

ATNR present

A

0-5 months

28
Q

A

pressure against the palm results in a grasp and slow release

29
Q

Palmar grasp present

Body righting reaction acting on the head (BOH)

A

contact of body with solid surface results in head righting with respect to gravity, interacts with labyrinthine righting reaction on head to maintain orientation of head in space
