[Digital goniometry "Spasmometr GC-2"]

The review of modern application of goniometric assessment in rehabilitation of patients with movement organs system disorders is done by the authors. The construction and principle of operation of digital goniometer, applied to pendulum testing of lower extremities with pathologic changed muscle tone, are described. An electro-optical transducer transmits the digitized time-dependent function of an angle between the thigh and leg axes of subject via an interface to the special computer programme. The function is registered, some coefficients describing extremity motion in joint are determined and the patient is assigned to the proper rehabilitation group by the composed programme. Normal values of the pendulum test coefficients in the asymptomatic subjects are performed.
