The electrically evoked long latency reflex (LLR) of the anterior tibial muscle: the impact of train stimuli and voluntary muscle contraction

Introduction: Previously, we have shown that the long latency reflex (LLR) recorded over the biceps brachii muscle can be augmented by (1) an increase in the level of isometric muscle contraction and (2) by electrical train stimuli as compared to single stimuli delivered over the superficial radial nerve (Alaid et al., Neurosci Lett, 2012;526:91 – 95). Objective: To investigate, whether the electrically evoked reflex responses over a leg muscle would behave in a similar way to changes in isometric muscle contraction and to train stimuli like over arm muscles. Materials/methods: LLR were recorded over the anterio…
