yea - fall down - break something - get scared - wobble - fall down - break someting - get scared.... that's obvious......how long did it take to study that ? 30 seconds ?we've got pd not brain-death. > Date: Wed, 18 Jul 2012 19:43:04 +0200 > From: [log in to unmask] > Subject: Emotional state affects gait initiation in individuals with Parkinson's disease. > To: [log in to unmask] > > Emotional state affects gait initiation in individuals with Parkinson's > disease. > Naugle KM, Hass CJ, Bowers D, Janelle CM. > Source > > Comprehensive Center for Pain Research, University of Florida, 1329 SW > 16th Street, Rm 5180, P.O.
