Figure 1.

(A) A participant used her index finger and thumb to form a C-shaped pose to allow her hand aperture to be determined. The examiner measured the distance (cyan line) between the finger tips as the length of the participant’s hand aperture. (B) A skeleton figure, depicted in the sagittal plane to show a representative reaching while standing trial when the participant reached a target box (cyan circle). The target was set at one arm’s length from the participant in alignment with the midline of his body to allow him to bend forward to reach and lift the target. (C) A skeleton figure depicted in the frontal plane to show a representative walking-for-reaching trial prior to the participant reaching the target box (cyan circle). The participant reached the box with his trunk facing forward and the right arm slightly extended to the right.
