Abstract
When a subject is instructed to resist external load, stretch-induced reflex responses can be observed in the emg of the contracting muscles when the load is abruptly increased. As commonly known, these reflex responses are grouped into segments denoted M1, M2 and M3 according to the nomenclature of Tatton et al. (1975). The long latency components have attracted particular attention; they have been studied in normal as well as in pathologic states, such as in parkinsonism and chorea.
