| Abstract: | Background In order to better understand the similarities and differences in the motor behaviour of different groups of patients, their
scores on the Motor Examination section of the Unified Parkinson's Disease Rating Scale (UPDRS) were analysed simultaneously.
The three groups consisted, respectively, of patients with Parkinson's disease (PD) on medication, patients with Parkinson's
disease withdrawn from anti-parkinsonian medication for at least 12 hours, and patients diagnosed with a specific Parkinsonism
syndrome: Progressive Supranuclear Palsy (PSP). |
