FIELD: medicine.SUBSTANCE: registration of biomechanical characteristics of the ankle joint work is performed by means of a hardware-software complex in the process of a step cycle with the application of a motion capture system, a dynamic stabiloplatform and electromyography (EMG). First, light-reflecting markers are fixed on the patient's body, devices of wireless EMG are fixed on anterior and posterior groups of the shin muscles. An individual three-dimensional static skeleton model of the patient, for which characteristics of the step cycle are determined by the patient walking on the stabilometric platform with the number of not fewer than 5 repetitions, is created by means of the motion capture system. The obtained biomechanical characteristics are used to calculate the power of the ankle joint work, the pronation angle and the supination angle by means of the complex software. Comparative analysis of the said parameters with the parameters of the norm, varying in the following ranges: power of work 3.01÷4.56 W/kg, pronation angle 3.89÷4.78 degrees, supination angle 2.98÷3.67 degrees, is carried out. Pes valgus deformation of feet is diagnosed if the power of the ankle joint work and the supination angle reduce, and the pronation angle increases in comparison with the norm.EFFECT: method provides the complex accurate quantitative early diagnostics of pes valgus deformation of the foot in children in short terms, taking into account the biomechanics of walking.2 ex |
