Akinesia

n. lack of movement, loss of movement (due to pathological causes)

Akinesia (from the prefix a-, "without", and the Greek κίνηση, kinisi, "motion") is the inability to initiate movement due to difficulty selecting and/or activating motor programs in the central nervous system. Common in severe cases of Parkinson's disease, akinesia is a result of severely diminished dopaminergic cell activity in the direct pathway of movement.
