drives motivation
SMOOTH follow
: 4w= horizontal, 6wks = vertical, 12m = all directions Response = synchronisation and tracking of visual stimulus. Ax = 4yo may need to hold head, 5yo verbally cue to not move head
12m = fast – some over/undershoot > 3y = more refined strategy
abnormal eye follow
eye follow: : Problems with eye follow may indicate brain‐stem dysfunction, poor VOR control or cranial nerve dysfunction therefore further assessment is indicated
fixate and release
= -4 = look for 3 secs and same for ax (3-5secs), 4+ = complete with monocular vision
converge
= 12 months = asymmetrical may be due to dysfunction or tightening of one of the ocular muscles which prevents movement in a direction
1m > 10cm, when cover of one eye, both eyes continue to act symmetrically
Optokinetic Nystagmus
= induce a visual nystagmus symmetrically when looking in both directions when looking at alternating stripes moving across VF – allows for visual stimulus to remain in focus as it passes across visual field * PRESENT AT BIRTH
Ocular HR - posture
is forward and backward and sideways, while VHR is vestibular, whole body perturbation; where the head should be in line with gravity, not the body
VHR
= 3MONTHS, ability 2 orient head to gravity when body is moved from vertical orientation. Atypical = neck stiffening, inc/dec tone, delayed
Ax = balance board in long sit if children – usual over 4yo can tolerate blind fold
OHR = OPTICAL HEAD RIDING
HHR
Horizontal = 4-5 mnths
Response = head remains oriented to gravity whilst body moves underneath
However, if child cannot hold head when held in prone be very careful in supine. Head should come above midline of the body in every position. Record extent of response; eg below, to, or above midline
Horizontal body righting
= same as above but whole body when in prone suspension. Automatic cervical, trunk, hip and knee extension and plantar flexion occurs when supported in a prone position.
4-5 = cervical ext first > 6 months = cervical, trunk, hip, knee, PF (head > pf order for ext)
body on body >
right (segmental rptation) trunk when Ul or LL is moved diagonally *AUTOMATIC POSTURAL ADJUSTMENT * 3-4M = SEGMENTAL ROT, 3-5Y = DEROTATE HEAD AND SHOULDERS AGAINST DIRECTION OF MVMT
- MSK IMPAIRMENTS = DISLOCAT. HIP CAN PREVENT ROLL, EN BLOC – HYPERTONIA, ASYYMETRY = DEC. MUSCLE LENGTH OR STRENGTH, LOSS OF SEGMENTAL ROTATION AT SPINAL LEVEL
