A system for quantitative assessment of dyscoordination and tremor.
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.
