Testretest reliability and rater agreements of Assessment of Capacity for Myoelectric Control version 2.0. J Rehabil Res Dev. 2014;51(4):635–44. http://dx.doi.org/10.1682/JRRD.2013.09.0197 Slideshow Project DOI:10.1682/JRRD.2013.09.0197JSP Aim – Evaluate test-retest reliability and rater agreements of Assessment of Capacity for Myoelectric Control (ACMC) version 2.0. Relevance – ACMC is an observation-based assessment that evaluates ability to control myoelectric prosthetic hand in bimanual activities – Stability of ACMC measures has not been evaluated over time.

Activity performances were: – Video recorded. – Assessed by 2 ACMC raters. Data were analyzed by: – Weighted kappa. – Intraclass correlation coefficient (ICC). – Bland-Altman.

Testretest reliability and rater agreements of Assessment of Capacity for Myoelectric Control version 2.0.

Interrater reliability – Weighted kappa agreements: fair to excellent. – ICC: 0.95 (test) and 0.92 (retest). Intrarater agreement – Excellent.

MDC value can be clinically useful. Further research is needed to determine: – Minimal clinically important difference. – Responsiveness of ACMC.
