Electro-control: am EMG-controlled A/K prosthesis
Medical & Biological Engineering, 1972Locking of the flexion of the knee-joint in this knee prosthesis can be accomplished by means of a mechanical clutch released by a control pulse which, in turn, is derived from the myolectric activity of the patient's stump. The feature enables the amputee to use the artificial leg as a reaction point for his residual muscles.

The Torque Control and Evaluation of the Ankle Prosthesis
2018 IEEE International Conference on Information and Automation (ICIA), 2018This paper presents the mechanical design and a control method for a prosthesis emulator which is consisted by a motor, a mechanical design and a transmission device. In order to release the burden of users in wearing such a device, it is of great importance to reduce the weight of the prosthesis, which also remains a paramount issue in the design of ...

AN ACTIVE EMG-CONTROLLED A/K PROSTHESIS
IFAC Proceedings Volumes, 1982Abstract A pressure reservoir in conjunction with a pneumatic piston and cylinder is employed to conserve a portion of the energy dissipated during swing phase by conventional A/K actuators. During the portion of the swing cycle when energy is to be supplied at the knee, the pressure reservoir serves as driver.

Position proprioception in a microcomputer-controlled prosthesis
Medical & Biological Engineering & Computing, 1987Powered upper-extremity multifunctional prostheses have been in existence for several decades. However, the acceptance rate by amputees of these devices is extremely poor. An examination of the reasons for the poor level of acceptance has revealed that a major problem is the absence of proprioception of the position of the prosthesis.

A myoelectrically-controlled prosthesis with sensory feedback
Medical & Biological Engineering & Computing, 1979An electrically-operated hand, controlled by myopotentials, has been fitted with strain gauges in the index finger which measure the gripping force between thumb and index finger. These strain gauges cause an electrical stimulus to be applied to the skin directly above the median nerve.

Control of an Electrical Prosthesis With an SSVEP-Based BCI
IEEE Transactions on Biomedical Engineering, 2008Brain-computer interfaces (BCIs) are systems that establish a direct connection between the human brain and a computer, thus providing an additional communication channel. They are used in a broad field of applications nowadays. One important issue is the control of neuroprosthetic devices for the restoration of the grasp function in spinal-cord ...

Neural Control of a Virtual Prosthesis
1998The abilities of the currently existing hand prostheses are typically limited to opening or closing the hand. This limits the usefulness of the prosthesis considerably compared to the many degrees of freedom in an intact hand. In order to develop more advanced hand prostheses two main problems have to be solved.
