Abstract
Objective: This research proposal aims to investigate the role of cognitive predictors—including attention, memory, spatial awareness, and executive function—in the mastery of EMG- controlled prostheses following Targeted Muscle Reinnervation (TMR) surgery. The study seeks to identify cognitive predictors that contribute to successful prosthetic control, which could inform tailored rehabilitation and training protocols.
Methods: A case-control design will be employed involving 30 participants who have undergone TMR surgery and have been fitted with trans-radial EMG-controlled prostheses. Participants will be divided into two groups: those who have successfully mastered their prostheses (cases) and those who have not (controls). Mastery will be evaluated through clinical evaluations, functional assessments, and user experience surveys. Cognitive functions will be assessed using the Trail Making Test (TMT), Box and Blocks Test (BBT), and the Mental Rotation Test (MRT). Statistical analyses will include t-tests to compare the two groups and regression analyses to identify the predictive value of various cognitive functions.
Significance: By elucidating the cognitive factors that influence prosthetic mastery, this study aims to enhance clinical outcomes for individuals using EMG-controlled prostheses. Improved understanding of these relationships could lead to more effective, customized training programs that accelerate proficiency and increase satisfaction among prosthetic users. The findings will also inform the design of future prosthetic devices, making them more user-friendly and aligned with the cognitive capabilities of their users.
