Tromner Sign on Physical Exam The Trömner sign is commonly used as a clinical neurological examination for upper motor neuron lesions above the fifth or sixth cervical segments of the spinal cord. A modified Rossolimo reflex in which, with the fingers of the patient partially flexed, the tapping of the volar aspect of the tip of the middle or index finger causes flexion of all four fingers and thumb; seen in pyramidal tract lesions with moderate spasticity. #Tromners #Sign #Reflex #clinical #Video #Neurology #physicalexam
