Официальное название
Determining the Long-Term Stability of the Glide Control Strategy for Upper Limb Prostheses
Обзор
This research is intended to test whether the prescription of the Glide prosthesis control system reduces the burden of use for both patients and their clinical care team as compared to use of Pattern Recognition-based advanced myoelectric control. The goal of the study is to fill the gaps in clinically relevant knowledge to inform the prescription of prosthesis components and the rehabilitation process.

- Устройство Glide Control System
Glide is a commercially developed directional myoelectric control strategy from Infinite Biomedical Technologies (IBT) that sits between classic Direct Control (DC) and modern Pattern Recognition (PR). Instead of requiring an isolated on/off muscle signal for each function (e.g., DC) or training a complex classifier on many gestures (e.g., PR), Glide uses the relative activity across 2-8 EMG electrodes to move a virtual cursor on a 2-D "Glide map." The map is divided into adjustable sectors ("sl - Устройство Pattern Recognition System
Pattern recognition (PR)-based myoelectric control is a data-driven approach that allows a user to control multiple prosthetic functions using natural muscle activation patterns rather than discrete, isolated signals. Instead of mapping one muscle to one motion (as in conventional Direct Control), PR systems record the spatial and temporal pattern of EMG activity from multiple sites on the residual limb and use machine learning algorithms to classify which intended movement the user is trying to
