What is the characteristic pattern seen in Brown sequard
syndrome -
a) C/L loss of joint sense and position
b) C/L loss of pain
c) I/L loss of complete sensory functions
d) C/L motor functions
Correct Answer - B
Answer: B - Contralateral loss of pain sensations
If the spinal cord is completely transected – All the sensations and
motor functions distal to segment of transection are blocked.
Transection of spinal cord on single side results in “Brown
Sequard Syndrome”
Functions affected:
Function
affected
Position Description
Motor Ipsilateral side Complete loss of motor
functions below the level of
transection
Sensory Combined effects
observed
Some sensory functions are
lost on transected side and
others on opposite side.
On the
Contralateral
side:
Sensation of pain,
cold, & heat
Result of disturbance in
Spinothalamic pathway.
Loss observed 2 to 6
segments below the level of
transection.
Discrete Crude
touch
Poorly localized (Still
persists).
Partial transmission occurs in
opposite Spinothalamic trac
