Hoffmann's Sign or Hoffmann Reflex for Neurological Screening of UMN Lesions<\/h2>\nThe Hofmann's Sign is also referred to as \"Digital reflex\", \"Snapping reflex\", \"Jacobson Sign\" or \"Trumner Sign\". When the spinal cord in the cervical spine gets compressed, chances are that the patient will exhibit pathological reflexes.\u00a0 According to Grialwa et al.(2015), it has a sensitivity of 59% and a specificity of 49% to screen for upper motor neuron lesion (UMN lesions) that can lead to those pathological reflexes.\n

Support the patient's hand so that it is completely relaxed with the fingers partially flexed. You can kind of cradle the patient's hand with your hand. Then grasp the patient's middle finger, proximal to the distal interphalangeal joint, and then flick the patient's nail of the middle finger with your thumb.\n\nThe test is positive if you're able to observe quick adduction of the\u00a0thumb and flexion of the index finger.\n\nOther tests for UMN lesions:\n
