"Pathophysiology of bradykinesia
in Parkinson's disease
The term bradykinesia was first used by James Parkinson to describe one of the cardinal features of the disease that now bears his name. It is now recognized, however, that bradykinesia
may be part of the motor dysfunction in many movement disorders.Bradykinesia
is often used synonymously with two other terms: akinesia
. Strictly speaking, bradykinesia
describes the slowness of a performed movement, whereas akinesia
refers to a poverty of spontaneous movement (e.g. in facial expression) or associated movement (e.g. arm swing during walking). Other manifestations of akinesia
are freezing and the prolonged time it takes to initiate a movement. Hypokinesia
refers to the fact that, in addition to being slow, the movements are also smaller than desired, as in the micrographia of patients' handwriting.”http://brain.oxfordjournals.org/content/124/1...
"The term “hypokinesia
” in PD encompasses three main components of reduced mobility: “bradykinesia
”, which is defined as reduced movement execution speed, “akinesia
”, which is defined as the paucity of spontaneous movement and slowness to initiate movement due to prolonged reaction times, and “hypometria
”, which is defined as reduced amplitude of movements (Marsden, 1982)."http://books.google.ch/books/about/Targeting_...
