摘要：
FIELD: medicine.SUBSTANCE: performing simultaneous recording of electrical muscle activity signals (EMG) of the upper and lower extremities while keeping the joint angle posture unchanged. From the EMG spectrum, the frequency range of the signal that creates the motor act is singled out. The power spectrum of the signal is calculated by the Fourier transform, the maximum peak is determined on the spectrum and its frequency is determined (FP) And power (A2P), and also the power of the constant component of the spectrum (A20). A polygon of the distribution of the parameterFP and determine on it the modeFMod and the fraction of the frequency that dominates the spectrum (FP) in one of the three frequency bands of the spectrum P1 - 3.8-6.4 Hz, P2 - 6.4-9 Hz, P3 - ≥9 Hz. Based on the values obtained the tremor coefficient (Km) as the ratio of the power of the frequency of the maximum point of the spectrum to the average power of all components of the spectrum frequencies except forA2P and A20, inμV2. For values of Fmod≥3≤6.4 Km≥8 P1≥0.6 diagnose tremor at Fmod≥6.4≤12 Km≥5≤30 P2≥0.6 - rigidity at Fmod≥9≤20 Km≤6 P3≥0.64 A2p≤15 - akinesia, with Fmod≥3≤10 Km≤8 P1≥0.45 P2≥0.2 A2p≥15 - mixed symptomatic-tremor-rigid form of BP Fmod≥3≤10 Km≥5≤30 P1≥0.2 P2≥0.45 rigid-trembling at Fmod≥6.4≤12 Km≥5≤15 P2≥0.45 P3≥0.2 is rigid-akinetic at Fmod≥6.4≤12 Km≥3≤10 P2≥0.2 P3≥0,45 is akinetic-rigid at Fmod≤6 Km≤8 P1≥0,3 - early preclinical tremor at Fmod≥6 Km≤5 P2≥0,3 A2p≥7 - early preclinical rigidity.EFFECT: method makes it possible to increase the reliability of diagnosis and to determine the specific forms of Parkinsons disease, which is achieved by isolating the informative parameters of the electrical activity spectrum of the muscles creating the motor act and calculating the tremor coefficient.4 cl, 9 dwg, 2 tblИзобретение относится к области медицины, в частности к неврологии.
