title: The crossed extensor hallucis response in neurological disorders; an electromyographic analysis.
abstract: The electromyographic activity in several leg muscles during the elicitation of "the crossed up-going toe sign" (CUT) was studied in patients and compared with that obtained in connection with the Babinski sign and in normal subjects. The results indicate that the patterns of activation and the responsible pathways are different for the CUT and Babinski signs. The difference between the normal subjects and the CUT positive patient is a matter of quantitative difference of coactivation of distal leg muscles during the test procedure rather than a change of reflex patterns.
