Abstract

Nine spiral nerve cuff electrodes were implanted in two human subjects for up to three years with no adverse functional effects. The objective of this study was to look at the long term nerve and muscle response to stimulation through nerve cuff electrodes. The nerve conduction velocity remained within the clinically accepted range for the entire testing period. The stimulation thresholds stabilized after approximately 20 weeks. The variability in the activation over time was not different from muscle-based electrodes used in implanted functional electrical stimulation systems. Three electrodes had multiple, independent contacts to evaluate selective recruitment of muscles. A single muscle could be selectively activated from each electrode using single-contact stimulation and the selectivity was increased with the use of field steering techniques. The selectivity after three years was consistent with selectivity measured during the implant surgery. Nerve cuff electrodes are effective for chronic muscle activation and multichannel functional electrical stimulation in humans.

  • Helical and spiral extra-neural interfaces have been stable for decades in clinical applications.

    “The helical (Agnew et al., 1989) and spiral (Naples et al., 1988) type interfaces have been proven to be stable for decades in clinical applications (Fisher et al., 2009; Polasek et al., 2009).”

    The Discussion reports stable recruitment from spiral nerve cuff electrodes in two human subjects for up to three years; the Introduction also describes a spiral cuff implanted in one person for over six years. These passages support clinical stability of spiral interfaces, but not stability for decades. They do not establish clinical stability of helical interfaces. (LLM, conf=0.90)

  • Electrical stimulation in the form of spikes has been given to the residual stump nerve of a patient through typically implanted electrodes, and psychophysical judgments and verbal reports were gathered.

    “Electrical stimulation in the form of spikes has been given to the residual stump nerve of a patient through typically implanted electrodes, and psychophysical judgments and verbal reports were gathered (Polasek et al., 2009; Schiefer et al., 2016).”

    Methods A and D describe implanted nerve-cuff electrodes delivering electrical pulses. But Methods C identifies the subjects as two people with tetraplegia, not a patient with a residual stump nerve; Methods D describes EMG measurements, not psychophysical judgments or verbal reports. No page numbers are available in our copy. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • In a 3-year clinical study with two subjects, spiral cuff electrodes provided stable and selective stimulation without serious adverse reactions, after achieving stable stimulation thresholds around the 20th week.

    “In a 3-year clinical study with two subjects, spiral cuff electrodes were shown to provide stable and selective stimulation without serious adverse reactions, after achieving stable stimulation thresholds around the 20th week [72].”

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.
