Description
Способ осуществляют следующим образом.The method is as follows.
На коленный сустав исследуемой конечности соосно оси сустава с помощью крепления фиксируют потенцио- 5 метрический гониометр.A potentiometric 5-meter goniometer is fixed on the knee joint of the studied limb coaxially to the axis of the joint using fastening.
Гибким проводом потенциометрический гониометр соединяют со стационарным электронным дифференциатором и гониометром. Испытуемому пред- Ю лагают пройти 7—10 м. Во время ходьбы производят регистрацию величины угловой скорости.With a flexible wire, a potentiometric goniometer is connected to a stationary electronic differentiator and a goniometer. The test subject is asked to walk 7-10 m. During walking, the angular velocity is recorded.
Сигнал первой производной суставного угла - угловая скорость - ре- 15 гистрируется на гониографе в виде характерной кривой, повторяющейся с каждым шагом.The signal of the first derivative of the articular angle - the angular velocity - is recorded on the goniograph in the form of a characteristic curve, repeated with each step.
На полученной кривой находят точки, которые отражают максимальное 20 значение угловой скорости в фазу сгибания и максимальное значение угловой скорости в фазу разгибания коленного сустава в опорном периоде исследуемой конечности.On the obtained curve, points are found that reflect the maximum 20 value of the angular velocity in the bending phase and the maximum value of the angular velocity in the phase of extension of the knee joint in the reference period of the studied limb.
Величину коэффициента отношения фаз сгибания и разгибания ( К вычисляют путем определения абсолютных значений угловой скорости или посредством метрических измерений.The magnitude of the ratio of the phases of flexion and extension (K is calculated by determining the absolute values of the angular velocity or by metric measurements.
Для вычисления коэффициента путем, определения абсолютных значений угловой скорости амплитуду полученных кривых делят на амплитуду калибровочного сигнала.To calculate the coefficient by determining absolute values of the angular velocity, the amplitude of the obtained curves is divided by the amplitude of the calibration signal.
II
Для вычисления коэффициента отношения угловой скорости метрическим путем производят измерение в миллиметрах амплитуд фазы сгибания и фазы разгибания от нолевой точки и делят их между собой. При значениях коэффициента,превышающих 7,диагностируют деформирующий артроз.In order to calculate the coefficient of the ratio of the angular velocity, the amplitudes of the bending phase and the extension phase from the zero point are measured in millimeters and divided among themselves. With coefficient values exceeding 7, deforming arthrosis is diagnosed.
