Slideshow Project DOI: 10. 1682/JRRD. 2012. 0231 JSP • Aim – Develop standardized activities for Assessment of Capacity for Myoelectric Control (ACMC) and examine influence of these activities on validity of ACMC. • Relevance – ACMC is an observation-based clinical tool that evaluates ability to control myoelectric prosthetic hand during bimanual activities.

Method Slideshow Project DOI: 10. 1682/JRRD. 2012. 0231 JSP • 6 activities were standardized for ACMC: – Repotting plant, ready-to-assemble project, setting table for 4 persons, mixing store-bought cake/pudding mix, sorting bills or pictures, packing suitcase. • Subjects performed 3 standardized activities. – Upper-limb myoelectric prosthesis users (47 congenital, 11 acquired). • Bias-interaction analysis in many-facet Rasch model identified inconsistent patterns: – In interactions of individual users and activity facets. – Between activities and user characteristics.

Results Slideshow Project DOI: 10. 1682/JRRD. 2012. 0231 JSP • Standardized activities did not significantly influence measures of user ability. • Activities functioned similarly across: – Both sexes. – Both prosthetic sides.

Conclusion Slideshow Project DOI: 10. 1682/JRRD. 2012. 0231 JSP • Results: – Provide evidence for validity of ACMC across standardized activities. – Support use of ACMC in prosthesis users of both sexes and prosthetic sides. • Newly standardized activities are recommended for future ACMC use.
