Differences between Novice and Expert Raters Assessing Trunk Control Using the Trunk Control Measurement Scale Spanish Version (TCMS-S) in Children with Cerebral Palsy

The Trunk Control Measurement Scale (TCMS) is a valid and reliable tool to assess static and dynamic trunk control in cerebral palsy. However, there is no evidence informing about differences between novice and expert raters. A cross-sectional study was conducted with participants between the ages of 6 and 18 years with a CP diagnosis. The TCMS Spanish version (TCMS-S) was administered in-person by an expert rater, and video recordings were taken for later scoring by the expert and three other raters with varying levels of clinical experience. The intraclass correlation coefficient (ICC) was used to evaluate reliability between raters for the total and subscales of the TCMS-S scores. Standard Error of Measurement (SEM) and Minimal Detectable Change (MDC) were also calculated. There was a high level of agreement between expert raters (ICC >= 0.93), while novice raters demonstrated good agreement (ICC > 0.72). Additionally, it was observed that novice raters had a slightly higher SEM and MDC than expert raters. The Selective Movement Control subscale exhibited slightly higher SEM and MDC values compared to the TCMS-S total and other subscales, irrespective of the rater's level of expertise. Overall, the study showed that the TCMS-S is a reliable tool for evaluating trunk control in the Spanish pediatric population with cerebral palsy, regardless of the rater's experience level.

Automated summary

The study confirmed that The Trunk Control Measurement Scale (TCMS) is a reliable tool for assessing static and dynamic trunk control in cerebral palsy patients. There were no significant differences between novice and expert raters. The study, conducted with Spanish pediatric population diagnosed with cerebral palsy, showed high agreement between expert raters (ICC ≥ 0.93) and good agreement among novice raters (ICC > 0.72). Novice raters had slightly higher Standard Error of Measurement and Minimal Detectable Change than expert raters. The Selective Movement Control subscale had slightly higher Standard Error of Measurement and Minimal Detectable Change values compared to the TCMS-S total and other subscales, regardless of the rater's level of expertise.
