Orthostatic arm outstretching test system and method applied to Rolandic epilepsy diagnosis

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 ...
