("香港《争鸣》杂志5月号披露，在上海写回忆录的江泽民于4月17日傍晚散步时再次中风，经随行保的健医生急救后被送华东医院抢救脱险，但下身瘫痪")

My comment:
(a) I did check 争鸣 website, which does not have any content, as usual.
(b)
(i) 中风导致下身瘫痪 is medically impossible. That is why you see hemiplegia at most.
(ii)
(A) "Hemi" means one side of the body -- right or left, but never up or down. Spinal cord injury may cause paraplegia 下身瘫痪 or quadriplegia (four limbs).
(B) -plegia (noun combining form; etymology): "paralysis"
https://www.merriam-webster.com/dictionary/-plegia
(C) Paralysis is the COMPLETE loss of skeletal muscle function, whereas paresis is PARTIAL loss of skeletal muscle function. (These two words concerns not smooth muscle (as in intestines) or sensations.
(iii) In neuroanatomy 神经解剖学, corticospinal tract starts from primary motor cortex 运动皮质, descends and 90 percent of which cross in medulla 延髓 (part of brain stem 脑干) to the other side of spinal cord to connect with spinal cord motor neurons, which innervates muscles of limbs. The remaining 10 % of corticospinal tract does not cross and, again connect with motor neurons of spinal cord to innervate trunk 身体躯干 muscles.  

The "cortico-" is the noun combining form for "cortex 大脑皮质."
(iv) A stroke can occur anywhere in the central nervous system, from brain to brain stem to spinal cord. The last is very rare.

If it happens in the brain stem, conceivably it may affect muscle of both sides of the body. However, brain stem is so important to life (it regulates breathing and heart beats, to name a few functions), that a stroke there is almost always fatal. Besides, with level so high a stroke there will affect not just four limbs but also muscles needed for breathing.

If a stroke happens in the brain, it may affect the OTHER side of the body (in motor or sensory function, depending on location of the stroke), or speech.
