Bilateral symptoms.
Upper ext are more medial
What is the classic history of Brown seqard syndrome?
Hemisection of cord due to penetrating injury
What are the symptoms seen in Brown-seqard syndrome?
- IPSILATERAL loss of motor function, propioception, & vibratory sensation. (MVP)
- CONTRALATERAL loss of pain and temperature. (OPT)
Must-know!
Brown Is my MVP hes a CPT
BROWN
B: Back pain (initially) R: Reduced proprioception and vibration sense (on the same side as the lesion) O: Opposite loss of pain and temperature sensation (on the contralateral side) W: Weakness and paralysis (on the same side as the lesion) N: Neurogenic bladder or bowel dysfunction
Cauda Equina Mnemonic
- Saddle anesthesia
- Pain (lower)
- Incontinence
- Numbness (groin/legs)
- Emergency (needs surgery)
SPINE
What nerve root does CES occur below?
L1
