The F-jitter was investigated in patients with polyneuropathy (PNP, n = 20), spasticity (SPS), ( n = 10) and in 30 healthy subjects.Results: The sensitivity of F-jitter was observed to be at least as much as of other parameters.Conclusions: It is therefore concluded that F-jitter might be a useful parameter to be included in new-generation digital EMG instruments beyond its significant contributions to physiological studies.Significance: The F-jitter values in PNP and SPS groups were significantly different from the healthy group, and this difference was more prominent in the PNP group

Abstract

Objective: F response is one of the late EMG responses occurring with peripheral motor nerve stimulation. It is generated by firing of anterior horn motor neurons as a result of antidromic propagation of the stimulus on the motor nerve. The aim of this study was to evaluate the feasibility of using average variability in consecutive F response latencies (F-jitter) as a new parameter. Method: The fundamental characteristic of the F-jitter distinguishing it from other parameters is that it describes the chrono-dispersion among the neurons stimulated consecutively. The F-jitter was investigated in patients with polyneuropathy (PNP, n = 20), spasticity (SPS), ( n = 10) and in 30 healthy subjects.Results: The sensitivity of F-jitter was observed to be at least as much as of other parameters.Conclusions: It is therefore concluded that F-jitter might be a useful parameter to be included in new-generation digital EMG instruments beyond its significant contributions to physiological studies.Significance: The F-jitter values in PNP and SPS groups were significantly different from the healthy group, and this difference was more prominent in the PNP group

Özet

Amaç: F dalgaları periferik motor sinir elektriksel uyarımı ile ortaya çıkan geç EMG yanıtlarından biridir. Motor sinir üzerinden antidromik sinyal akışı ile ön boynuz hücresinin aktive olması ile ortaya çıkmaktadır. Bu çalışmanın amacı ardışık F yanıtlarının latans değikenliğinin yeni bir F yanıtı değerlendirme ölçeği olarak kullanılabilirliğini araştırmaktır. Yöntem: ASrdışık F yanıtları değişkenliği 30 normal kontrol, 20 polinöropati ve 10 spastik hastada çalışılmıştır.Sonuçlar: F jitter değerleri en azından diğer F yanıtı ölçekleri kadar sensitive bulunmuştur. Sonuç: Biz F jitterinin yeni nesil EMG cihazlarına algoritması yerleştirilerek kolayca rutin kullanıma girebilecek nitelikte ve özellikle motor nöron fizyolojisi çalışmalarında kullanılabilecek özellikte olduğu fikrindeyiz.
