What is fanning of toes?
(fan′ing) Spreading of toes, esp. when the sole is stroked; plantar reflex.
What type of reflex is Babinski?
The Babinski reflex, also called the Babinski sign or plantar reflex, is an automatic reflex in the foot in response to stimulation. Joseph Babinski, a French neurologist, first documented the reflex in 1896. Testing for the Babinski reflex involves stroking the sole of the foot and assessing the response in the toes.
What causes the Babinski sign?
Babinski sign occurs when stimulation of the lateral plantar aspect of the foot leads to extension (dorsiflexion or upward movement) of the big toe (hallux). Also, there may be fanning of the other toes. This suggests that there is been spread of the sensory input beyond the S1 myotome to L4 and L5.
Is Babinski reflex and plantar reflex?
The abnormal plantar reflex, or Babinski reflex, is the elicitation of toe extension from the “wrong” receptive field, that is, the sole of the foot. Thus a noxious stimulus to the sole of the foot produces extension of the great toe instead of the normal flexion response.
What type of reflex is the plantar reflex?
Superficial Reflexes The plantar reflex is the most common superficial reflex examined. A stimulus (usually by the handle end of a reflex hammer) is applied on the sole of the foot from the lateral border up and across the ball of the foot. A normal reaction consists of flexion of the great toe or no response.
What is H-reflex response?
The H-reflex (or Hoffmann’s reflex) is a reflectory reaction of muscles after electrical stimulation of sensory fibers (Ia afferents stemming from muscle spindles) in their innervating nerves (for example, those located behind the knee).
What is the T reflex?
Tendon reflex (or T-reflex) may refer to: The stretch reflex or muscle stretch reflex (MSR), when the stretch is created by a blow upon a muscle tendon. This is the commonly used definition of the term. Albeit a misnomer, in this sense a common example is the standard patellar reflex or knee-jerk response.
What is M wave and H-reflex?
An M-wave, an early response, occurs 3-6 ms after the onset of stimulation. The H and F-waves are later responses. As the stimulus increases, the amplitude of the F-wave increases only slightly, and the H-wave decreases, and at supramaximal stimulus, the H-wave will disappear.
What happens during the patellar reflex?
The patellar reflex occurs when an abrupt change arises in muscle length; in this case, it is produced by the tendon stretching, which is caused when the hammer stroke is applied [3, 4]. The normal response must be a sudden leg extension.
