Abstract [en]

Introduction: The Assessment of Capacity for Myoelectric Control (ACMC) is an observational based instrument that evaluates the ability to operate a myoelectric prosthetic hand. It is performed during the execution of bimanual tasks chosen by the clients. Although the ACMC does not assess task performance, it is unknown whether the clients’ ability measures are influenced by factors such as task complexity. The study aim was therefore to develop standardized tasks and to examine whether (i) the clients’ ability measures are influenced by the tasks (ii) the tasks function the same across different client characteristics based on age, sex, prosthetic side and experience.

Method: Six tasks were chosen from ACMC raters’ suggestions and standardized for the ACMC. Myoelectric prosthesis users (n=58, mean age=20, 31 males) were recruited from the Örebro University Hospital, Sweden. Each user performed 3 tasks. All task performances were videotaped and rated on the 22 ACMC items according to a 4-point capability scale.Many-facets Rasch analysis was used to (i) examine whether the three ability measures of each user were significantly different from each other, and (ii) to reveal if a particular client characteristics was scored differently in a particular task.

Result: No significant difference in the ability measures was found in the majority of the sample – only three sporadic users were significantly different in one or two of their tasks. This implies that the client’s ability measures are not influenced by the tasks. No significant difference was found related to prosthetic side and experience. Minor difference was found in sexes and two age groups (age 7 to 15, over 15) but the differences were too small to be clinically relevant.

Conclusions: This study provides further validity evidence of the ACMC. Research with more challenging tasks is needed to confirm the findings.
