Patients with neurological disorders of the Central Nervous System (CNS) like Parkinson's disease, CVA or Complex Regional Pain Syndrome (CRPS) often exhibit symptoms in their peripheral systems. These symptoms are seen in the motor control system, the thermoregulation system, the autonomous system regulating the bloodflow, etc. Standardized methods to measure these symptoms can be used as diagnostic methods (whether or not to include the patient for a certain patient category), quantifying the severity of the disease, i.e. for monitoring the disease progress or the efficacy of medicine, and/or for exploring the underlying disease mechanism.
