Visuomotor behaviours when using a myoelectric prosthesis [PDF]

, 2014
Background: A recent study showed that the gaze patterns of amputee users of myoelectric prostheses differ markedly from those seen in anatomically intact subjects.

Fuzzy EMG classification for prosthesis control [PDF]

IEEE Transactions on Rehabilitation Engineering, 2000
This paper proposes a fuzzy approach to classify single-site electromyograph (EMG) signals for multifunctional prosthesis control. While the classification problem is the focus of this paper, the ultimate goal is to improve myoelectric system control performance, and classification is an essential step in the control. Time segmented features are fed to

Mechatronic design & adaptive control of a lower limb prosthesis [PDF]

, 2020
Lower limb prostheses have undergone significant developments in the last decades. However, there are several areas that have a scope for improvement through simplifications in the mechatronic design as well as in the control architecture.

Towards Prosthesis Control: Identification of Locomotion Activities through EEG-Based Measurements

Robotics
The integration of advanced control systems in prostheses necessitates the accurate identification of human locomotion activities, a task that can significantly benefit from EEG-based measurements combined with machine learning techniques.

Investigation of Timing to Switch Control Mode in Powered Knee Prostheses during Task Transitions. [PDF]

PLoS ONE, 2015
Current powered prosthetic legs require switching control modes according to the task the user is performing (e.g. level-ground walking, stair climbing, walking on slopes, etc.).

Automated Instability Detection for Interactive Myocontrol of Prosthetic Hands

Frontiers in Neurorobotics, 2019
Myocontrol is control of a prosthetic device using data obtained from (residual) muscle activity. In most myocontrol prosthetic systems, such biological data also denote the subject's intent: reliably interpreting what the user wants to do, exactly and ...

Development of a theoretical model for upright postural control in lower limb prosthesis users

Scientific Reports, 2021
Methods used to assess quiet standing in unilateral prosthesis users often assume validity of an inverted pendulum model despite this being shown as invalid in some instances.

A Hybrid Controller Integrating Finite-State Impedance and Electromyography-Driven Musculoskeletal Model for Robotic Active Ankle Prostheses: A Case Study

IEEE Access
Finding a balance between adaptability for unexpected or non-standard movements and repeatability for cyclic standard movements is a known control challenge for active lower-limb prostheses.

EMG-Based Control of Active Ankle-Foot Prosthesis

Journal of Engineering, 2023
 Most below-knee prostheses are manufactured in Iraq without considering the fast progress in smart prostheses, which can offer movements in the desired directions according to the type of control system designed for this purpose.
