2.3.1. GMFM 66
The GMFM was designed to measure changes in gross motor function in children with CP; it assesses motor function (how much of the task the child can perform) rather than the quality of motor performance (how well the child performed the task). The GMFM comprises five major testing sub-items: (A) lying and rolling; (B) sitting; (C) crawling and kneeling; (D) standing; and (E) walking, running, and jumping. The scoring system ranges from 0 to 3, where 0 indicates ‘no initiation’, 1 indicates ‘initiation’, 2 indicates ‘partial completion’, and 3 indicates ‘completion’ [
