AKA Reinforcement Test
pt hooks hands/feet together and pulls on clenched hands or feet at the moment the reflex is performed
Uvular/Palateal Reflex

Interscapular Reflex
Drawing inward of scapula when skin or interscapular space is irritated
Abdominal Reflex
Umbilicus deviation to stroked side.
Absence is only normal if bilateral (Beevor Sign)
Plantar Reflex
Plantarflexion (curling) of toes upon stroking sole of foot
Fakuda Step Test
pt marches in place, eyes closed, for 50 steps
( + ) a turning to one side
( i ) vestibular lesion on the side of rotation
Barognosis
Ask pt to identify difference between two same sized objects of different weight
Evaluating integrity of somatosensory cortex
Schaefer Sign
Squeezing of achilles tendon to elicit Babinski’s (alternative)
Ankle Clonus
Continued involuntary contraction (sustained plantar flexion) of foot upon quick
forcible dorsiflexion of the foot
Pallesthesia of foot
Place handle of vibrating 128Hz fork on joint line of lower extremity
Utilize 3 distal interphalangeal joints, if abnormal, continue to evaulate proximally until normal finding is achieved at base of 5th metatarsal, or medial and lateral malleoli.
Ask pt to identify when he or she feels vibration and when dr has stopped the vibration
( + ) inability to identify
( i ) dorsal column involvment

Fajersztajn Test
AKA Well-Leg-Raising Test of Fajersztajn
AKA Cross-over Sign
pt supine, dr performs SLR on UNAFFECTED leg to 75* or until produces pain down affected leg
if NO PAIN, examiner dorsiflexes foot
( + ) pain down affected leg (cross-over sign)
( i ) medial disc protrusion
( + ) decrease in pain down affected leg
( i ) lateral disc protrusion
Extraocular Movements
(Cardinal fields)
Evaluating CN III, IV, VI
(oculomotor, trochlear, abducens)
observe pts eyes for normal conjugate/parallel movements of eyes and nystagmus as you have them follow finger or pencil while making wide “H” in the air
(CN4/IV) Trochlear = down and in
(CN6/VI) Abducens = lateral
(CN3/III) Oculomotor = all others
