DEVICE FOR DETRMINING AND RECORDING ATAXIA AND OTHER EXTREMITY MOVEMENT DISORDERS, ESPECIALLY OF LOWER HUMAN EXTREMITIES S

摘要

Device for determination and recording of ataxia and other disorders of movement of limbs, in particular the human lower limbs, containing two slider elements capable of relative movement situated along the body of the patient and performing measurement functions relating to parameters of the patient's limbs, characterized in that it consists of an elastic lower band (1) fastened on the ankle joint of the patient, having a lower distance slider sleeve (2) fastened rigidly to the band at a right angle relative to the axis of the tested limb, while mounted detachably in the sleeve, so as to allow rotation and sliding movement, is a lower intermediate pin (3), whose free end is connected, preferably non-detachably, in a lower articulated joint (4) which has at least two degrees of freedom of movement and is fastened rigidly on the outer end of a slider sleeve (5), inside which is a slide-fitting telescopic plunger (6), which has fastened close to its free end a similarly constructed upper articulated joint (7) with at least two degrees of freedom of movement, mounted in which is an upper intermediate pin (8), which slides in and has a detachable connection with an upper distance slider sleeve (9), which is fastened rigidly, at a right angle relative to the axis of the tested limb, to an upper elastic band (10) fastened on the patient's hip or shoulder, while at the end of the plunger (6), beyond the point where the upper articulated joint (7) is fixed, is a permanent magnet (12) fastened rigidly on an angular extension arm (11) at a right angle relative to the tested limb, the magnet being mounted slidably inside a special induction coil (13) connected by an elastic cable (14) to an x-t graphic recorder (15).IMAGE
