(Top) Histogram of the number of synergies to account for greater than 90% of the variance in EMG data (N90) for the children with CP (pre-treatment and post-treatment). (Bottom) Average (+/− 1 SD) total variance accounted for (tVAF) by one to five synergies for the children with CP (pre-treatment and post-treatment). The TD tVAF is shown in grey (average +/− 1 SD) for comparrison. *indicates significant change in tVAFn following treatment (p < 0.05).
