Simultaneous Multi-Joint Myoelectric Control of Transradial Prostheses
… coordinated manner. Commercially available myoelectric control algorithms are unintuitive, allow only a single degree of freedom to be operated at a time, and typically require some type of a mode switch to transition between operating the various functions of the system. Pattern …

An intelligent prosthetic hand using hybrid actuation and myoelectric control
… DC and Shape Memory Alloy (SMA) actuation and controlled by only two myoelectric sensors. A prosthesis as a tool makes no pretence of trying to replace the lost limb physiologically but it works as an aid to help provide some of the lost functions and is an interchangeable device worn and used …

Effects of training methods on classification on surface electromyographic signals for myoelectric control
Myoelectric devices, devices which use the electric signals from human muscles as a control scheme, have shown promise in their potential to aid in human movement augmentation and assistance for those that have suffered injury. Previous studies involving myoelectric devices and the classification …

EMG control of prosthetic ankle plantar flexion
… available prostheses are intrinsically controlled. Users cannot intuitively change ankle controller's behavior to perform movements that are not part of the repetitive walking gait cycle. For example, when transition from level ground walking to descending stairs, user cannot intuitively …

Prosthesis Design and Object Recognition Based Grasping of a 3D Printed Anthropomorphic Artificial Hand
… Such computationally heavy methods also utilize myoelectric control, which requires training for an extended period of time. In this work, by utilizing intrinsic information of an object, such as color and edge information, the computational time is reduced while still providing the user with …

Mechanisms for enabling closed-loop upper limb sensorimotor prosthetic control
Myoelectric upper limb prostheses are limited in their ability to provide sensory feedback to a user. The lack of sensory feedback forces prosthesis users to rely on visual feedback alone in manipulating objects, and often leads to abandonment of the prosthesis in favor of the user's unimpaired …

EMG as a control parameter in lower limb prosthetics : surface vs. implanted electrodes
Human locomotion is controlled by complex neurological patterns. These patterns activate and synchronise the musculoskeletal system to enable efficient and graceful ambulation. A limb amputation results in a partial loss of the complex structure needed for human locomotion. Various prosthetic …

Surface myoelectric signal analysis and enhancement for improved prosthesis control
… techniques are presented in the field of myoelectric control. Specifically, algorithms for activity detection, noise identification and noise reduction are introduced, evaluated and discussed. The ultimate aim has been to develop algorithms to improve the performance of prosthetic control …

The effect of socket design on the reliability of EMG signal transduction in trans-radial myoelectric prostheses
Background: The majority of trans-radial myoelectric prosthesis users experience some level of difficulty and disruption in the control of their prosthesis everyday (1). Previous studies by Head (1) and Chadwell et al. (2) have suggested that the fit and/or design of the socket could be a …

Novel Methods for Recording and Analysing High-Density EMG Signals of the Hand & Forearm
… in the human body. These potentials, called myoelectric activity, can be registered and analysed using non-invasive recording electrodes in a technique known as surface electromyography (sEMG). Key information about the muscles can then be extracted from EMG signals using signal processing …
