False with regard to pyramidal weakness:
A. Hip flexors are often weaker than knee flexors
B. Wrist flexors will usually overcome wrist extensors
C. It may occur in the absence of any sensory signs
D. It is a early presentation in syringomyelia

Ans.
D. It is a early presentation in syringomyelia
In pyramidal weakness the flexors are
usually stronger than the extensors in the upper limbs and the reverse in the
lower limbs. Hip flexion is often weaker than ankle dorsiflexion which in turn
is weaker than knee flexion. Ankle clonus and ankle jerks use the same 15 / SI
reflex pathway. Motor neurone disease, hereditary spastic paraparesis and
parasagittal meningiomas may all cause pyramidal weakness without sensory
signs.
