Implementation of natural sensory feedback in a portable control system for a hand grasp neuroprosthesis

Inmann, Andreas, Haugland, Morten·2004·Medical Engineering & Physics

Abstract

This paper presents the design and implementation of the first generation of a portable system for a hand grasp neuroprosthesis that is controlled by means of signals from natural sensors in the skin of the index finger. To reduce development time and costs, we based our design on readily available, standardised modules such as a 486DX100 compatible CPU, a data acquisition board, a flash disk storage unit, and a high-efficiency DC/DC switch-mode power supply. Additionally, we designed and built a telemeter to supply an implanted muscle stimulator with power and control data. The signal from the natural sensors was recorded with a cuff electrode implanted around the palmar digital nerve innervating the radial aspect of the index finger. For amplification of the recorded nerve signal, we added an external low-noise nerve signal amplifier. For pre-processing of the recorded nerve signal, an optimised band-pass filter was used. A data-recording unit allowed storage and off-line analysis of the stimulator command and the recorded nerve signal. The portable system was used by a tetraplegic volunteer to test the feasibility of including natural sensors in a hand grasp neuroprosthesis for activities of daily living. The flexibility of the presented system allows rapid prototyping of experimental FES hand grasp systems intended for portable use.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • For hand grasp neural prosthesis, a cuff around the palmar digital nerve recorded mechanoreceptor activity when a grasped object was slipping to regulate grasping force.

    “for hand grasp neural prosthesis, a cuff placed around the palmar digital nerve recorded the activity from mechanoreceptors when a grasped object was slipping to regulate the force of grasping (Haugland and Hoffer, 1994; Haugland et al., 1994; Inmann and Haugland, 2004)”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
