This research aimed to evaluate intra-rater and inter-rater reliability of the Segmental Assessment of Trunk Control (SATCo) for measuring segmental approach of trunk control in children with cerebral palsy. Participants were 30 children with cerebral palsy mean age 10.1 ± 4.11 years, Gross motor Function Classification System (GMFCS) level II-V. Two assessors conducted SATCo include three tests (static trunk control, active trunk control, and reactive trunk control) and independently scored from recorded videotapes in two times. Rescored were carried out within two weeks from the first scoring. The intra-rater reliability of the test subjects was determined using the first scoring. Intra-rater and inter-rater reliability were calculated using intraclass correlation coefficients (ICC 3, k) and (ICC 2, k) respectively. The significance level was set at p<0.05. The results of the study showed that intra-rater reliability of the SATCo in static trunk control, active trunk control and reactive trunk control were excellent for the total data set at ICC (3, k) ranking from 0.90 to 1.00. Inter-rater reliability of the SATCo in static trunk control, active trunk control and reactive trunk control were excellent (ICC 2, k) ranking from 0.93 to 0.99 across all data sets and aspects of trunk control. Rater of the SATCo is reliable allowing clinicians greater specificity in assessing degree of trunk control.
