When I saw this posting, I wondered about the affect of spasticity on  
muscle atrophy too.  I would guess spasticity makes us use muscles  
even though it is in ways that we might not want to!  But I can also  
attest that after almost 3 years of me not doing my usual water  
aerobics 2-3 times a week, I have lost a ton of muscle mass.  There  
is only so much muscle to be gained from chasing after a toddler!
