COMPUTER-AIDED NONINVASIVE ASSESSEMENT OF THE DYNAMICS OF PATHOLOGICAL TREMOR IN SKELETAL MUSCLES

Patološki tremor je najpogostejša gibalna motnja, ki prizadene okoli 5 % ljudi starejših od 50 let. Zaradi ritmičnega tresenja tako zgornjih kot spodnjih okončin predstavlja resno funkcionalno motnjo. Bolnike lahko ovira pri vsakodnevnih dejavnostih, v najhujših oblikah pa lahko privede do popolne izgube samostojnosti. V magistrskem delu smo implementirali računalniško podprte postopke za vrednotenje časovne in prostorske dinamike patološkega tremorja iz večkanalnih površinskih signalov EMG ekstenzorjev in fleksorjev zapestja bolnikov s Parkinsonovim in esencialnim tremorjem. Postopke smo vgradili v računalniško aplikacijo, ki omogoča spremljanje amplitude, frekvence in prostorske porazdelitve tremorja v preučevani mišici.Pathological tremor is the most common movement disorder and affects about 5% of population over the age of 50 years. Because of rhythmic shaking of upper and lower extremities it presents a serious functional disorder that affects practically all the activities of daily living and can, in the worst case, lead to complete loss of autonomy. We implemented a computer-aided procedures for assessment of temporal and spatial dynamics of pathological tremor from multichannel surface EMG signals, recorded from the wrist extensors and flexors in patients with Parkinson\u27s and essential tremor. These procedures were integrated into a computer application, which allows tracking of the tremor amplitude, frequency and spatial distribution in the investigated muscle
