If an adult has a positive Babinski reflex, however, it is likely that they have a nervous system disorder.Įxamples of these disorders could include: The reflex typically goes away by the time a child reaches 2 years old. When a doctor does the Babinski sign test on a child, the reflex will cause their toes to fan out and the big toe to move upward. The patient demonstrates positive results. This video demonstrates how the Hoffman’s sign test and Babinski sign test is performed. The Babinski sign is different from the Hoffman sign in that it involves testing the lower extremities instead of the upper ones. Identified and presented by Joseph Babinski in 1896, this test involves stroking a person’s sole to check their reflex response. Researchers of this journal article found that a positive Hofmann’s sign had a high clinical correlation with cervical dysfunction.Īnother reflex test is the Babinski sign. The Hoffman’s sign test can help to confirm a doctor’s suspicions, which might lead them to order other tests, such as imaging studies or blood work.Īlthough it may seem like a simple examination, the Hoffman’s test delivers a “substantial” result when it comes to positive findings, according to the Journal of Orthopaedic & Sports Physical Therapy. Reflex tests, such as the Hoffman’s test, are useful because they are low-cost.
If someone has a positive Hoffman’s sign on only one side, this is more likely to indicate a nervous system injury, according to the Indian Journal of Medical Specialties. have other medical conditions that can cause hyperreactivity.have a condition such as hyperthyroidism (overactive thyroid).Sometimes a person may have a positive Hoffman’s sign if they: This damage may result in a person having a more exaggerated response to stimulation, such as during the Hoffman’s sign test.ĭoctors may use the Hoffman’s sign test along with other tests to determine whether a person has a medical condition that affects the spine.
When the nerves become damaged, however, these protective capabilities are less effective. Typically, the nervous system works to temper the spinal reflexes, so a person does not overreact to stimuli. In the case of the Hoffman’s sign, this occurs when the nervous system overreacts to the flick on the fingernail. A positive response is known as hyperreflexia. If the index finger and thumb move, the person has a positive Hoffman’s sign.Ī doctor may notice the movement more profoundly if the person is extending or flexing their neck. If there is no movement in the index finger or thumb after this motion, the person has a negative Hoffman’s sign.
