Embodiment 1

[0035] On the one hand, the erect arm extension test system applied to the diagnosis of Rolandic epilepsy, such as Figure 1-Figure 3 As shown, it includes a myoelectric detection system for measuring myoelectric signals and an electroencephalogram detection system for measuring electroencephalogram signals. The myoelectric detection system includes a plurality of myoelectric detection boards 1, a data acquisition card 4 and an electromyography analysis terminal 2. One end of the data acquisition card 4 is connected to the myoelectric detection board 1 through the data acquisition line 3, and the other end of the data acquisition card 4 is connected to the myoelectric analysis terminal 2 through the data transmission line 5. The myoelectric detection board 1 includes a substrate 11 and is installed on the substrate. A plurality of myoelectric electrodes 12 on the top of 11 and a base plate 13 arranged at the bottom of the base plate 11, a pair of chute 14 is provided on the out...

Embodiment 2

[0037] As the second embodiment of the present invention, in order to facilitate the detection of myoelectric signals, the inventors make improvements to the myoelectric electrode 1 as a preferred embodiment, such as Image 6 As shown, the electromyographic electrode 12 is also provided with an electrode acquisition module, a signal amplification module, a filter module, a differential voltage regulation module and a power supply module, the electrode acquisition module is used for collecting and detecting electromyographic signals, and the signal amplification module is used for collecting The EMG signal is amplified and processed, the filter module filters out interference signals and redundant signals, and collects effective EMG signals. The differential voltage regulation module is used to adjust the shifted EMG signal to the reference position, and the power supply module is used for Electrical electrodes 12 provide power. In this embodiment, the signal amplification modu...

Embodiment 3

[0046] As a third embodiment of the present invention, in order to facilitate the filter processing of the electromyographic signal, the inventors made improvements to the filter module as a preferred embodiment, such as Figure 7 As shown, the filtering module includes a high-pass filtering module, a low-pass filtering module and a band-stop filtering module. In this embodiment, since the frequency of the collected myoelectric signal is in the range of 1-1000 Hz, the energy of the myoelectric signal is mainly concentrated in the frequency range of 10-200 Hz, so it is necessary to filter the myoelectric signal to filter out some interference signals and redundant signals , to collect effective EMG signals. This embodiment adopts a high-pass filter module. The high-pass filter module is a second-order high-pass filter of a voltage-controlled voltage source. The second-order high-pass filter circuit of a voltage-controlled voltage source is composed of a resistor, a capacitor, an...

Abstract

The invention relates to the technical field of an epilepsy detection system, in particular to an orthostatic arm outstretching test system and method applied to Rolandic epilepsy diagnosis. The orthostatic arm outstretching test system comprises a myoelectricity detection system for measuring a myoelectric signal and an eeg detection system for measuring an eeg signal. The orthostatic arm outstretching test method is adopted, and does not have adverse reactions and after effects; negative myoclonus seizures can be found at an early date through the orthostatic arm outstretching test, so that the positive rate is increased; the orthostatic arm outstretching test can assist clinical early stage diagnosis, prognosis is judged, intervention is performed in advance, cognizant damage to a child patient is reduced, powerful evidence for clinical diagnosis is provided, the correct rate of diagnosis and differential diagnosis of the epilepsy is greatly increased, and missed diagnosis and delayed treatment are prevented; negative myoclonus seizure synchronous electromyography presents that in continuous and stable medium amplitude myoelectric activity, the myoelectric activity of an upper limb on one side or upper limbs on two sides is subjected to tranquillization or obvious attenuation, the synchronous electroencephalogram presents the phenomenon of spike-slow wave distribution generated mainly in opposite-side Rolandic region or bilateral Rolandic regions, and the orthostatic arm outstretching test system provides powerful evidence for correctly diagnosing epilepsy seizures, performing further treatment and judging prognosis.

Description

technical field [0001] The invention relates to the technical field of epilepsy detection systems, in particular to an upright outrigger test system and method applied to the diagnosis of Rolandic epilepsy. Background technique [0002] Epilepsy is one of the most common chronic neurological diseases in childhood, with a prevalence rate of 3%-10%, and 60% of onset in childhood. Benign Rolandic epilepsy in children is the most common epilepsy syndrome in childhood, and the incidence rate in the population is 21 / 100,000, accounting for 15%-24% of various childhood epilepsy. The peak age of onset is school-age children (3-13 years old), and 75% of them have onset between 5-10 years old. The child's psychomotor development was normal, and neurological and neuroimaging studies were normal. After appropriate antiepileptic drug treatment, most of the patients have a good prognosis and do not affect the intellectual motor development of the children. However, some of the children ...
