Title
(EN) METHODS AND SYSTEM FOR CHARACTERISING TREMORS
(FR) PROCÉDÉS ET SYSTÈME DE CARACTÉRISATION DE TREMBLEMENTS
Abstract
(EN) A method of characterising tremor stability in a subject is described for a subject having an involuntary tremor symptomatic of a neurological disorder. The method comprising: identifying a series of tremor cycles from measured tremor data of the subject, said tremor cycles measuring periodic variation in movement of the subject due to the tremor; determining an instantaneous frequency for each tremor cycle and collating the instantaneous frequencies; determining an instantaneous variation between the instantaneous frequencies of each pair of adjacent tremor cycles within the series; comparing the instantaneous variation to the collation of determined instantaneous frequencies to determine a distribution of instantaneous variations; and determining an index value of the distribution of the instantaneous variations, said index value defining the stability of the tremor.
(FR) L'invention concerne un procédé de caractérisation de la stabilité des tremblements chez un sujet ayant un tremblement involontaire symptomatique d'un trouble neurologique. Le procédé consiste à : identifier une série de cycles de tremblement à partir de données de tremblement mesurées du sujet, lesdits cycles de tremblement mesurant une variation périodique du mouvement du sujet en raison du tremblement; déterminer une fréquence instantanée pour chaque cycle de tremblement et collationner les fréquences instantanées; déterminer une variation instantanée entre les fréquences instantanées de chaque paire de cycles de tremblement adjacents dans la série; comparer la variation instantanée à la collation de fréquences instantanées déterminées pour déterminer une distribution de variations instantanées; et déterminer une valeur d'indice de la distribution des variations instantanées, ladite valeur d'indice définissant la stabilité du tremblement.
