- Ask you to hold out your hand and relax it so that the fingers are loose.
- Hold your middle finger straight by the top joint with one hand.
- Place one of their fingers on top of the nail on your middle finger.
- Flick the middle fingernail by quickly moving their finger down so that your nail and your doctor’s nail make contact with each other.

Overactive Bladder Detrusor hyperreflexia is bladder overactivity associated with a neurologic disorder. Common disorders that manifest detrusor hyperreflexia are stroke, Parkinson's disease, dementia, spinal cord injury, and multiple sclerosis.
What does Babinski sign indicate?
The presence of the Babinski reflex is indicative of dysfunction of the CST. Oftentimes, the presence of the reflex is the first indication of spinal cord injury after acute trauma. Care must be exercised in interpreting the results because many patients have significant withdrawal response to plantar stimulation.

Usually considered a pathological reflex in a clinical setting, the Hoffmann's reflex has also ...
Hoffmann's Sign - Physiopedia
Dr. Johann Hoffmann, a German neurologist, is credited with the discovery of the eponymous Hoffmann's sign or reflex.[1] Although his assistant, Dr. Hans Curschman, is responsible for the dissemination of this finding, leading to its universal use in neurological screening today.[2]

Not all doctors consider the Hoffman test to be a reliable diagnostic tool by itself, because your response to the test can be affected by other factors.
Is a positive Hoffman sign a sign of MS?
The bottom line. A positive Hoffman sign isn’t necessarily a cause for concern. But your doctor may suggest additional tests if you get a positive sign and have other symptoms of conditions like MS, ALS, hyperthyroidism, or spinal compression.
What is the Hoffman sign?
It was described by his assistant Hans Curschmann in 1911 and has become a standard part of the common neurologic exam.[1] The Hoffman sign is an involuntary flexion movement of the thumb and or index finger when the examiner flicks the fingernail of the middle finger down. The reflexive pathway causes the thumb to flex and adduct quickly. 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.
Is the Hoffman sign a stand alone predictor of spinal cord compression?
While the Hoffman sign can help as a screening tool, it is not reliable as a stand-alone predictor of spinal cord compression. Degenerative cervical myelopathy is a spinal cord dysfunction that can lead to numbness, pain, imbalance, sensory loss, hyperreflexia, and urinary incontinence. Estimates are that nearly 1.6 per 100000 have had surgical treatment for cervical myelopathy.[2] During a standard neurological exam, the Hoffman sign is common, and a positive sign can aid in the diagnosis. However, a 2018 systematic review, with level 1 evidence, on the utility of the Hoffman sign for the diagnosis of degenerative cervical myelopathy found insufficient data to support the use of the exam alone to confirm or refute a diagnosis of degenerative cervical myelopathy.[3] While the Hoffman sign can help as a screening tool, clinicians cannot rely on it as a stand-alone predictor of spinal cord compression.
How do you get the Hoffman sign?
To get the Hoffman sign take the relaxed hand of the patient with the wrist flexed down and the heart finger partially flexed. The examiner will hold the middle finger of the patient by placing it between his index finger and his middle finger.

What is the Hoffman sign?
Your neurological finger tapping reflex, also known as the Hoffman sign, is used to identify damage to the central nervous system and monitor recovery from brain injury. This reflex is triggered by stimulated neurons triggering a cascade of voluntary skeletal muscle contractions known as evoked muscle accidents (EMCA).

What does a positive Hoffmann's reflex mean?
A positive Hoffmann’s reflex and finger jerks suggest hypertonia, but can occur in healthy individuals, and are not useful signs in isolation. In cerebellar diseases, the reflexes may be pendular, and muscle contraction and relaxation tend to be slow, but these are not sensitive or specific to cerebellar signs.
What is the name of the test that can help verify the presence or absence of issues arising from the cortico?
Hoffmann's reflex. 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.

What is a positive Babinski sign?
A positive Babinski sign is considered a pathological sign of upper motor neuron disease except for infants, in whom it is normal, whereas a positive Hoffmann's sign can be present in an entirely normal patient. A positive Hoffmann's sign in the normal patients is more commonly found in those who are naturally hyper-reflexive (e.g. 3+ reflexes). A positive Hoffmann's sign is a worrisome finding of a disease process if its presence is asymmetrical, or has an acute onset.

Is Hoffmann's reflex a plantar reflex?
Hoffmann's reflex is a deep tendon reflex (spindle fibre) with a monosynaptic reflex pathway in Rexed lamina IX of the spinal cord, normally fully inhibited by descending input. On the other hand, the plantar reflex is more complicated and not a deep tendon reflex, and its pathway is both more complicated and not fully understood.
What is the Hoffman's sign?
Hoffman’s sign or reflex is a test that doctors use to examine the reflexes of the upper extremities. This test is a quick, equipment-free way to test for the possible existence of spinal cord compression from a lesion on the spinal cord or another underlying nerve condition. The sign takes its name from a German neurologist called Johann Hoffman.
How to tell if a person has a positive Hoffman's sign?
holding the middle finger at the joint closest to the fingernail. “flicking” the nail of the person’s middle finger, using their other hand.
