Cognitive Workload Assessment of Upper-Limb Prosthetic Devices


Limb amputation can cause severe functional disability for the performance of activities of daily living (ADLs). Amputees use prosthetic devices on a regular basis to perform ADLs. Prosthetic devices require substantial amount of cognitive resources, which can lead to device rejection. However, prior research was mainly focused on measuring physical performance of using prosthetic devices. Assessing cognitive workload of prostheses is critical to ensure device usability. This study investigated models for classifying cognitive workload in electromyography (EMG)-based prosthetic devices with various types of input features, metrics, and tasks. The proposed algorithms can help manufacturers and clinicians predict cognitive workload of future EMG-based prosthetic devices in early design phases.
