This indicates a potential neurological issue, often related to upper motor neuron lesions. Also known as pyramidal drift or barré sign, pronator drift denotes a pathological sign observed during a neurological test or examination A positive pronator drift test indicates a potential issue in the brain or spinal cord that affects motor control

This article explains the meaning of a positive test, its possible causes, and what steps to take next.
Pronator drift in medicine, pronator drift (also known as pyramidal drift) refers to a pathologic sign seen during a neurological examination
[1] jean alexandre barré is credited with having first described it Thus it is sometimes known as the barré test or sign A positive result indicates palsy. In medicine, pronator drift (also known as pyramidal drift) refers to a pathologic sign seen during a neurological examination
Jean alexandre barré is credited with having first described it In pronator drift, the affected arm will slowly drift down and the hand may pronate Assessing rapid alternating movements involves asking the patient to perform a series of repetitive movements as quickly though dexterously as possible. The pronator drift test helps to assess motor function, muscle strength, coordination, and normal proprioception or position sense.
The pronator drift can be defined as a sign of a delicate disorder of the upper motor neuron, even though this condition can equally be found in some other conditions like metabolism inborn errors and others
This condition requires neurological examination in order to confirm the effect on the body. Pronator drift occurs because the muscles selectively innervated by the corticospinal tract, the extensors and supinators, are weakened
