Neurological Assessment Demonstrating Mild Postural and Intention Tremors with Preserved Proprioceptive Function. This video demonstrates a mild postural tremor involving distal joints of both hands rather than involvement of the wrist or elbow. A head tilt is noted to the right, and head tremor is irregular. On finger to nose maneuver, intention tremor is evident, although worse on the left, where mild dysmetria briefly evident. Romberg’s sign is negative, indicating preserved proprioceptive function. Tandem gait abnormalities were not evident in this assessment.
