Design, Construction and Tests of a Low-Cost Myoelectric Thumb

Technologies, 2021
Myoelectric signals can be used to control prostheses or exoskeletons as well as robots, i.e., devices assisting the user or replacing a missing part of the body. A typical application of myoelectric prostheses is the human hand. Here, the development of

Adaptation to random and systematic errors: Comparison of amputee and non-amputee control interfaces with varying levels of process noise. [PDF]

PLoS ONE, 2017
The objective of this study was to understand how people adapt to errors when using a myoelectric control interface. We compared adaptation across 1) non-amputee subjects using joint angle, joint torque, and myoelectric control interfaces, and 2) amputee

Real-Time Control of a Multi-Degree-of-Freedom Mirror Myoelectric Interface During Functional Task Training

Frontiers in Neuroscience, 2022
Motor learning mediated by motor training has in the past been explored for rehabilitation. Myoelectric interfaces together with exoskeletons allow patients to receive real-time feedback about their muscle activity.

Recent Advances in Myoelectric Control for Finger Prostheses for Multiple Finger Loss

Applied Sciences, 2021
The loss of one or multiple fingers can lead to psychological problems as well as functional impairment. Various options exist for replacement and restoration after hand or finger loss.

Wrist speed feedback improves elbow compensation and reaching accuracy for myoelectric transradial prosthesis users in hybrid virtual reaching task

Journal of NeuroEngineering and Rehabilitation, 2023
Background Myoelectric prostheses are a popular choice for restoring motor capability following the loss of a limb, but they do not provide direct feedback to the user about the movements of the device—in other words, kinesthesia. The outcomes of studies

Joint speed feedback improves myoelectric prosthesis adaptation after perturbed reaches in non amputees

Scientific Reports, 2021
Accurate control of human limbs involves both feedforward and feedback signals. For prosthetic arms, feedforward control is commonly accomplished by recording myoelectric signals from the residual limb to predict the user’s intent, but augmented feedback

Simultaneous Control of 2DOF Upper-Limb Prosthesis With Body Compensations-Based Control: A Multiple Cases Study

IEEE Transactions on Neural Systems and Rehabilitation Engineering, 2022
Controlling several joints simultaneously is a common feature of natural arm movements. Robotic prostheses shall offer this possibility to their wearer.

Effects of vibrotactile feedback and grasp interface compliance on perception and control of a sensorized myoelectric hand.

PLoS ONE, 2019
Current myoelectric prosthetic limbs are limited in their ability to provide direct sensory feedback to users, which increases attentional demands and reliance on visual cues.

Locomotor adaptation to a powered ankle-foot orthosis depends on control method

Journal of NeuroEngineering and Rehabilitation, 2007
Background We studied human locomotor adaptation to powered ankle-foot orthoses with the intent of identifying differences between two different orthosis control methods. The first orthosis control method used a footswitch to provide bang-bang control (a
