Index Patient II.3, on phase: There are muscle jerks of the upper body, resulting in shoulder shrugging, bringing the shoulder forward and backward, thrusting of the trunk, and facial grimacing. These movements cease completely when asked to perform motor tasks and most probably represent tics. Finger tapping is irregular and hand movements are bradykinetic bilaterally but more pronounced on the right side. Stride length and velocity are normal when he is walking, and there is physiological arm swing, but his steps appear a bit wooden.Segment 2. Index Patient II.3, off phase: Eye blinding is increased, and there are several facial tics. Bradykinesia of both hands is more pronounced than in the on state. His gait is small-stepped and shuffling with markedly reduced arm swing bilaterally.
