The Changes in Rats with Sciatic Nerve Crush Injury Supplemented with Evening Primrose Oil: Behavioural, Morphologic, and Morphometric Analysis

Table 1

The scoring and grading of the toe-spreading reflex.

⁢Toe-spreading reflex (Gutmann 1942)
Grade	Clinical symptoms
Degree 0	Absence of any abduction (movement) in any digit.
Degree I	Just visible spreading of the 4th toe alone (or one of the digit)
Degree II	Slight spreading of all three toes
Degree III	Spreading of all three toes less forceful than normal
Degree IV	Full spreading of all three toes (which resembles the; unoperated left site)

The toe-spreading reflex is an excellent and sensitive indicator of the onset of nerve and motor neuron recovery [24].
