Babinski reflex and the CUT reflex--a comparative study.

The Babinski reflex and the CUT reflex were examined in 150 neurological patients and 20 controls. A positive CUT reflex occurred more frequently than a positive Babinski reflex in the patient material as a whole, and in different diagnostic groups. However, there was a low grade of correspondence between a positive CUT reflex and a positive Babinski reflex. There were many positive CUT reflexes in the group of normal persons. In a number of cases the examination of the CUT reflex was impossible because of lack of strength or incooperability. The study indicates that the CUT reflex and the Babinski reflex are not comparable phenomena.

Babinski reflex by sural stimulation and dysfunction of descending motor pathway.

The aim of the study was to find out the relationship between the Babinski reflex and flexor polysynaptic reflexes which was evaluated by sural nerve stimulation, and to evaluate the descending motor pathway in involvement by cervical and transcortical cranial stimulation (TCCS) in a group of patients that were diagnosed as having the Babinski sign with either hemiparetic of hemiplegic, due to a cerebrovascular accident. In the normal population no significant responses were seen from the EHL by sural stimulation and these responses were recorded from the BF with a latency of 88 msec. In the patients who had Babinski reflex responses, signs could be easily recorded from EHL by sural stimulation with a latency of 166 msec. In this group, reflex responses from the BF were recorded with a latency of approximately 100 msec. Responses from the EHL were evaluated in 100% ratio by TCCS with a latency of 33.4 msec. in the normal group. The responses recorded from EHL by TCCS and latency was 47.5 msec. in 35.7% of the patients, who having Babinski sign. In 100% of the normal population, responses were evaluated with a latency of 28.8 msec. from EHL by cervical stimulation. In only 55% of the patients having the Babinski sign, responses were recorded in the same limb with a latency was 32.3 msec. These results support a different mechanism that control the EHL muscle in comparison to the BF muscle having dysfunction of descending motor tracts due to a pyramidal lesion.

[The cutaneous extensor plantar reflex (Babinski, 1896/1898)].

The extensor plantar reflex was described by Babinski in 1896. Given the obvious relevance of the sign for internal medicine as well as the paucity of translations of the original sources into Portuguese, we thought it timely to recall the ingenious arguments Babinski used to demonstrate his views on the "toe phenomenon", as he would call it. A careful analysis of Babinski's writings suggests, further, that he was driven by keen intuition as well as by medico-legal interests.

The Babinski reflex.

The plantar response is a reflex that involves not only the toes, but all muscles that shorten the leg. In the newborn the synergy is brisk, involving all flexor muscles of the leg; these include the toe 'extensors', which also shorten the leg on contraction and therefore are flexors in a physiological sense. As the nervous system matures and the pyramidal tract gains more control over spinal motoneurones the flexion synergy becomes less brisk, and the toe 'extensors' are no longer part of it. The toes then often go down instead of up, as a result of a segmental reflex involving the small foot muscles and the overlying skin, comparable to the abdominal reflexes. With lesions of the pyramidal system, structural or functional, this segmental, downward response of the toes disappears, the flexion synergy may become disinhibited and the extensor hallucis longus muscle is again recruited into the flexion reflex of the leg: the sign of Babinski. A true Babinski sign denotes dysfunction of the pyramidal tract, and should be clearly distinguished from upgoing toes that do not belong to the flexion synergy of the leg. Correct interpretation of the plantar response depends only to a minor degree on the method or site of stimulation of the foot. It is therefore most important to assess the response in the entire leg.
