The electrically evoked long latency reflex of the biceps brachii muscle: the impact of train stimuli, preceding stimuli, and voluntary muscle contraction.

Long latency reflex (LLR) responses were examined over the biceps brachii (BB) at different contraction levels after electrical single or train stimuli over the ipsilateral superficial radial nerve with an inter-stimulus interval of 3ms. Two constant motor waves were present, LLR2 with a peak latency value of 53±4ms and LLR3 with 85±10ms. LLR responses… CONTINUE READING
