The daughter. Segment 1 shows the 40-year-old daughter with her neck turned to the right and very mild posturing of the hands (mainly the right hand) while keeping her arms outstretched. The neck turning fluctuated in severity, worsening with attention and movement and while walking. The posture disappeared with distraction maneuvers and at times faded completely during the examination and/or when attention was distracted. Segment 2 at 2-months follow-up assessment and Segment 3 at 4-months follow-up assessment show the disappearance of symptoms and signs; although mild hypertrophy of the left SCM and slight right shoulder elevation can still be seen.
