A myoelectric prosthesis controller

2003 IEEE 29th Annual Proceedings of Bioengineering Conference, 2003
Myoelectric prostheses are preferred for their natural way of control and enhanced cosmetic restoration. Developing a software program that proportionally controls an upper limb myoelectric prosthesis is our target. Software processing of the (EMG) signal was performed by extracting the energy, RMS, and zero crossings features from the EMG signal, and ...

Prosthesis-guided training of pattern recognition-controlled myoelectric prosthesis

2012 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2012
Pattern recognition can provide intuitive control of myoelectric prostheses. Currently, screen-guided training (SGT), in which individuals perform specific muscle contractions in sync with prompts displayed on a screen, is the common method of collecting the electromyography (EMG) data necessary to train a pattern recognition classifier.

A control unit for myoelectrically controlled prosthesis

Proceedings of the First Joint BMES/EMBS Conference. 1999 IEEE Engineering in Medicine and Biology 21st Annual Conference and the 1999 Annual Fall Meeting of the Biomedical Engineering Society (Cat. No.99CH37015), 2003
The long time for getting an acceptable response in myoelectric prosthesis has been a problem. Thanks to DSP processors, the myoelectric signal (MES) processing time has had a drastic reduction. This paper describes a control unit for a myoelectric prosthesis using statistic variables related to contraction force.

Design and Control of a Powered Transfemoral Prosthesis [PDF]

International Journal of Robotics Research, 2008
The paper describes the design and control of a transfemoral prosthesis with powered knee and ankle joints. The initial prototype is a pneumatically actuated powered-tethered device, which is intended to serve as a laboratory test bed for a subsequent self-powered version. The prosthesis design is described, including its kinematic optimization and the

Biomechanics: Surface electromyography prosthesis control

2012 5th International Conference on BioMedical Engineering and Informatics, 2012
This paper provides a method to control a robotic arm by analyzing Electromyogram (EMG) collected from surface of the forearm. The electrodes are strategically placed on top of a particular muscle to harvest its myoelectric signals generated by physiological variations associated with muscular activities such as contraction and retraction.

Sensory control of a multifunction hand prosthesis

Biosensors, 1987
The current generation of prostheses that are fitted to limb deficient individuals have only a single degree of freedom which limits their functional range. Furthermore, electrically powered prostheses have a limited user input. Electrical signals generated by the contraction of muscles in the user's stump open and close the hand in an 'on and off ...

Prehensile control of a hand prosthesis by a microcontroller

Journal of Biomedical Engineering, 1991
The functional replacement of a natural hand and wrist is usually achieved by a split hook or an electrically powered and myoelectrically controlled artificial hand with one degree of freedom. In contrast to the commercial devices, this paper describes an experimental hand with four electric motors, nineteen sensors, and control algorithms which are ...

An anthropomorphic controlled hand prosthesis system

Journal of Zhejiang University SCIENCE C, 2012
Based on HIT/DLR (Harbin Institute of Technology/Deutsches Zentrum fur Luft- und Raumfahrt) Prosthetic Hand II, an anthropomorphic controller is developed to help the amputees use and perceive the prosthetic hands more like people with normal physiological hands. The core of the anthropomorphic controller is a hierarchical control system.

A running controller for a powered transfemoral prosthesis

2012 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2012
This paper describes a running controller for a powered knee and ankle prosthesis. The running controller was implemented on a powered prosthesis prototype and evaluated by a transfemoral amputee subject running on a treadmill at a speed of 2.25 m/s (5.0 mph).
