A regenerative peripheral nerve interface allows real-time control of an artificial hand in upper limb amputees

Open access

Abstract

Peripheral nerves provide a promising source of motor control signals for neuroprosthetic devices. Unfortunately, the clinical utility of current peripheral nerve interfaces is limited by signal amplitude and stability. Here, we showed that the regenerative peripheral nerve interface (RPNI) serves as a biologically stable bioamplifier of efferent motor action potentials with long-term stability in upper limb amputees. Ultrasound assessments of RPNIs revealed prominent contractions during phantom finger flexion, confirming functional reinnervation of the RPNIs in two patients. The RPNIs in two additional patients produced electromyography signals with large signal-to-noise ratios. Using these RPNI signals, subjects successfully controlled a hand prosthesis in real-time up to 300 days without control algorithm recalibration. RPNIs show potential in enhancing prosthesis control for people with upper limb loss.

  • Probably not a substantial claim. 15
  • It may state two separate claims as one. 38

  • The paper relies on this without support.

    The attempted phantom finger movements made by participants correspond to volitional motor commands in the residual nerves that can drive RPNI contractions.

    “Participants were asked at the beginning of each behavioral task whether they could move the fingers of their phantom limb. In this situation, the RPNIs were observed contracting during movement of the phantom fingers.”
  • The paper relies on this without support.

    The signals recorded from RPNI electrodes are efferent motor action potentials generated by the RPNI grafts rather than by other sources.

    “In both participants, large amplitude, anatomically appropriate motor control signals were recorded from the indwelling RPNI electrodes (n = 2,3).”
  • The paper relies on this without support.

    Both the median and ulnar nerves supply several intrinsic thumb muscles that help flex the thumb CMC and MCP joints.

    “This is anatomically appropriate since both the median and ulnar nerves innervate several intrinsic muscles, which assist in flexing the thumb CMC/MCP joints.”
  • The authors state this as an assumption.

    The thumb state vector represents thumb flexion/extension and thumb opposition/reposition position and velocity.

    “We assume that the thumb state vector xt represents the position and velocity of the thumb flexion/extension and thumb opposition/reposition.”

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.

A language model drew the claims from the paper on 2026-09-28, under version 3 of the claim definition (prompt extract-v3).

A second model labelled each claim on 2026-09-28 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

Cited sources are checked with a language model’s help (gpt-6-sol).

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.
