TLDR
This paper (Part II of two) presents an experimental demonstration of the performance achieved by implementing the mathematically derived optimal myoprocessor, and excellent agreement of the experimental results with the analytical predictions verifies the mathematical analysis.Abstract:
This paper (Part II of two) presents an experimental demonstration of the performance achieved by implementing the mathematically derived optimal myoprocessor described in Part I. Almost an order-of-magnitude improvement over the common myoprocessor is obtained. Excellent agreement of the experimental results with the analytical predictions verifies the mathematical analysis. The relative contributions of each stage of the optimal myoprocessor are examined. A discussion and comparison of several existing and proposed techniques for myoprocessor improvement are presented.read more

EMG feature evaluation for movement control of upper extremity prostheses
TL;DR: A new feature, the EMG Histogram, is introduced and shown to be the most effective of the group and done on the data acquired from the residual biceps and triceps muscle of an above-elbow amputee.

TL;DR: It is shown that a lag of approximately 0.08 ± 0.02 sec. exists between peak electrical activity and peak tension of human muscle, which should be taken into account in the analysis of rapid movements.

Interpretation of myoelectric power spectra: A model and its applications
L.H. Lindstrom,R.I. Magnusson +1 more
TL;DR: In this article, a mathematical model describing the power spectrum of myoelectric signals is presented, where the influences of electrode cofiguration and of biological parameters such as muscle-fiber radius, action-potential conduction velocity, spread of synapses over the innervation zone, number of fibers per motor unit, and electrode-to-muscle distance are expressed in terms of filter functions modifying the shape of the generator signal.

A microprocessor system for multifunctional control of upper-limb prostheses via myoelectric signal identification
TL;DR: Real-time on-line results are presented, as recently obtained from tests carried out on a 1969 Vietnam above-elbow amputee who had most severe nerve and muscle loss at his stump, and could therefore not use more than one or two electrode pairs.

Sheldon Baron,David L. Kleinman +1 more
TL;DR: A mathematical model of the instrument-monitoring behavior of the human operator is developed, based on the assumption that the operator behaves as an optimal controller and information processor, subject to his inherent physical limitations.
