title: A system for quantitative assessment of dyscoordination and tremor.
abstract: An item of electronic equipment which yields objective measures of motor disabilities is described. Three types of tests are included in the measuring procedures: a pursuit tracking with pseudo-randomly moving target, a free-wheeling and a tremor test. One force joystick and two low friction movement joysticks of different lengths serve as two-dimensional transducers, and a set of parameters describing the performance of the patient is calculated by a microprocessor. The system is intended to serve as an aid at neurological examination, and is expected to be valuable in cases of long-time evaluation of a medical treatment. Some preliminary results are given from tests on normal persons and patients.
