Original abstract
One could distinguish between "off freezing", which is a symptom tightly bound to L-dopa dosage and titration, and is clinically bound to wearing off, and, on the contrary, "on freezing" which does not respond to therapy modifications or to different drug's titration. On freezing seems to be related to frontal-basal ganglia-pontine neural pathway disruption. This neural disruption may be related with altered perception of extra and peri-personal space which are two major problems of these patients. We demonstrate in a group of patients with "on freezing" evident defect of attention, focus capability, of set-shifting properties, and of alteration in body/space relationship. We discuss on results obtained by specific training of physiotherapy with an review on literature.
