INVERTED SUPINATOR SIGN FOR CERVICAL MYELOPATHY According to Cook et al. (2009), the Inverted Supinator Sign has a sensitivity of 61% and a specificity of 78% in the detection of cervical cord compression. Like the Hoffmann's sign, it does not have a huge clinical impact as a stand-alone test, but is helpful when used in conjuction with other tests. Again, if you suspect CSM, this needs to be discussed with the patient's GP or specialist as surgery might be necessary to prevent irreversible dama

Cervical Myelopathy - Inverted Brachioradialis Reflex : The fingers flex when the radius is tapped, but there is no reflex contraction in brachioradialis. The triceps jerk is brisk. This is because the lower motor neurones and pyramidal tracts are damaged at the C5–6 level, producing lower motor neurone signs at that level and upper motor neurone signs below. Common causes of Cervical Myelopathy include Cervical Spondylosis, Cervical cord compression due to tumor, abscess, Trauma to cervical spi

CERVICAL SPONDYLOTIC MYELOPATHY (CSM): INVERTED SUPINATOR SIGN The inverted supinator sign is the last test (next to the Babinski and Hoffmann's sign) in the cluster of Cook to screen for CSM as a red flag in the cervical spine. According to Cook et al. (2009), the Inverted Supinator Sign has a sensitivity of 61% and a specificity of 78% in the detection of cervical cord compression. Like the Hoffmann's sign, it does not have a huge clinical impact as a stand-alone test, but is helpful when used
