A patient with dropped head before (A,B) and after (C,D) continuous intrajejunal infusion of levodopa-carbidopa intestinal gel (LCIG). After infusion of LCIG, the angle of antecollis was reduced in a natural position (A-C) and in a position with the neck averted with maximum effort (B-D). The black line is located between the vertex (Cz) and seventh spinous process.

The angle of dropped head was calculated with the use of "Image J" software by drawing a line between the vertex (Cz) and the seventh spinous process, as described previously (Figure 1). The angle of dropped head was 39.39  before the infusion of LCIG (Figure 1A). The angle in the natural position improved to 14.04  (Figure 1C). On maximum effort to avert the neck, the angle decreased from 28.17 to 9.73  (Figures 1B,D).
