What does a positive Hoffman sign mean?
A positive Hoffman sign indicates an upper motor neuron lesion and corticospinal pathway dysfunction likely due to cervical cord compression. However, up to 3% of the population has been found to have a positive Hoffman without cord compression or upper motor neuron disease.[2]
What is a normal Hoffman sign?
Perform a sharp and forceful flick of your thumb, making contact with the nail of the subject’s middle finger. The subject’s finger will flex immediately followed by relaxation. The presence of Hoffmann’s sign is characterized by flexion and adduction of the thumb and flexion of the index finger.
What is a Hoffmans test?
The Hoffman sign refers to the results of the Hoffman test. This test is used to determine whether your fingers or thumbs flex involuntarily in response to certain triggers. The way that your fingers or thumbs react may be a sign of an underlying condition affecting your central nervous system.
What does Hoffman’s test for?

What does Hoffman’s reflex test?
The Hoffman test is used to assess upper motor neuron function based on how your fingers and thumbs respond to stimulus, whereas the Babinski test is used to assess upper motor neuron function based on how your toes respond to stroking the bottom of your foot.
What is upper motor neuron disease?
Upper motor neuron diseases are a heterogeneous group of disorders in which a degeneration of motor neurons of the cortex and tronchoencephalic motor nucleus occurs. Clinically, these disorders are characterized by weakness, motor clumsiness, spasticity, and hyperreflexia.
Is upper motor neuron disease fatal?
Some people live with the condition for many years. MND can significantly shorten life expectancy and, unfortunately, eventually leads to death.
What is the Hoffmans test?
The Hoffman test determines whether a person has spinal cord damage. During this quick test, you hold out one of your arms and open your palm facedown, extending your fingers in front of you. Your doctor will then flick your middle fingernail.
What is a Hoffman test?
Hoffman Sign is a neurological examination used to assess the presence of an upper motor neuron lesion from spinal cord compression. It’s also referred to as the digital reflex, the snapping reflex, Tromner sign and jakobson sign.
How do you test for Hoffmann’s reflex?
The test involves tapping the nail or flicking the terminal phalanx of the middle or ring finger. A positive response is seen when terminal phalanx of the thumb flexes. A positive Hoffman’s reflex may indicate an upper motor neuron lesion or a pyramidal sign. Hoffmann’s reflex may be seen in the following conditions:
What does a positive Hoffman’s reflex mean?
A positive Hoffman’s reflex may indicate an upper motor neuron lesion or a pyramidal sign. Hoffmann’s reflex may be seen in the following conditions: – Diseases which cause spinal cord compression (myelopathy) such as cervical spondylitis, tumors, or degenerative arthritis.
What is Hoffmann’s sign?
Hoffmann’s reflex ( Hoffmann’s sign, sometimes simply ” Hoffmann’s “, also finger flexor reflex) is a neurological examination finding elicited by a reflex test which can help verify the presence or absence of issues arising from the corticospinal tract.
