Abstract A device for quantification of involuntary body movements is described. Patients are situated within the low-intensity radiation beam of a Doppler radar motion transducer. This device converts all body movements into one electrical signal which contains information on the size and trajectory of the moving parts of the body. This signal is processed in such a way that the obtained ‘quantity of motion’ Q within a certain period is proportional to the number of movements, the length of their trajectory and the size of the involved parts of the body. Therefore the obtained parameter is closely related to the burden that the movements exert on the patient. The low-cost device is very simple to apply and the results are online available.
