Abstract

Modern hand and wrist prostheses afford a high level of mechanical sophistication, but the ability to control them in an intuitive and repeatable manner lags. Commercially available systems using surface electromyographic (EMG) or myoelectric control can supply at best two degrees of freedom (DOF), most often sequentially controlled. This limitation is partially due to the nature of surface‐recorded EMG, for which the signal contains components from multiple muscle sources. We report here on the development of an implantable myoelectric sensor using EMG sensors that can be chronically implanted into an amputee's residual muscles. Because sensing occurs at the source of muscle contraction, a single principal component of EMG is detected by each sensor, corresponding to intent to move a particular effector. This system can potentially provide independent signal sources for control of individual effectors within a limb prosthesis. The use of implanted devices supports inter‐day signal repeatability. We report on efforts in preparation for human clinical trials, including animal testing, and a first‐in‐human proof of principle demonstration where the subject was able to intuitively and simultaneously control two DOF in a hand and wrist prosthesis.

  • Penetrating electrodes are mostly rigid enough to maintain structural integrity in muscle.

    “The penetrating electrodes are mostly rigid enough to maintain their structural integrity in the muscle.[367,368]”

    From Flexible Electronics and Devices as Human–Machine Interfaces for Medical Robotics (2022) · cites this paper as [367]

    The Materials and Methods section (IMES technical description; page unavailable) describes electrodes on a ceramic-packaged implant, and the Results (Animal experiments; page unavailable) report that implanted devices operated without problems and did not migrate in chronic animal studies. Those observations support stability of this particular implant in muscle, but the paper does not establish that penetrating electrodes are mostly rigid or that rigidity maintains their structural integrity.

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.
