clonus

[ro__0]

  A member of my family has recently been diagnosed with CLONUS as an explanation for his slurred speech and inability to walk due to stiffness.  Everything I have read indicated CLONUS will cause severe shaking, is stiffness also possible with CLONUS?  Could you please explain CLONUS and the possible effects on the body?  Could the stiffness eventually turn to paralysis due to the CLONUS?  All of this came about approximately a year after under going a kidney transplant.  Thank you.

Clonus is not a diagnosis, it is the name of a symptom or sign which is found in
numerous neurological diseases.
Clonus is associated with stifness, spacticity and increased tone in
muscles and is due to damage to the nerve supply to the affected muscles,
in particular the nerve which stretches fron the brain to the spinal cord.
Damage can be due to anything from a stroke to cerebral palsy to trauma.
Clonus takes the form of severe reperetive jerking of a muscle when it
is stretched and as I indicated above it is simultaneously associated with
stiffness.
I cannot discuss the outcome or prognosis of this problem however ,without
knowing the underling cause.
Clonus alone is not an adaquete diagnosis, there has to be an underlying
disease. Using the term clonus like this is a bit like saying  
'abdominal pain " without knowing whether it is due to appendicitis,
gallstones , ulcers etc.
