Abstract

Current myoelectric prostheses allow transradial amputees to regain voluntary motor control of their artificial limb by exploiting residual muscle function in the forearm. However, the overreliance on visual cues resulting from a lack of sensory feedback is a common complaint. Recently, several groups have provided tactile feedback in upper limb amputees using implanted electrodes, surface nerve stimulation, or sensory substitution. These approaches have led to improved function and prosthesis embodiment. Nevertheless, the provided information remains limited to a subset of the rich sensory cues available to healthy individuals. More specifically, proprioception, the sense of limb position and movement, is predominantly absent from current systems. Here, we show that sensory substitution based on intraneural stimulation can deliver position feedback in real time and in conjunction with somatotopic tactile feedback. This approach allowed two transradial amputees to regain high and close-to-natural remapped proprioceptive acuity, with a median joint angle reproduction precision of 9.1° and a median threshold to detection of passive movements of 9.5°, which was comparable with results obtained in healthy participants. The simultaneous delivery of position information and somatotopic tactile feedback allowed both amputees to discriminate the size and compliance of four objects with high levels of performance (75.5%). These results demonstrate that tactile information delivered via somatotopic neural stimulation and position information delivered via sensory substitution can be exploited simultaneously and efficiently by transradial amputees. This study paves a way to more sophisticated bidirectional bionic limbs conveying richer, multimodal sensations.

  • A recent clinical study with two transradial amputees has proven the capability of TIME electrodes in improving sensory feedback when combined with non-invasive somatotopic neural stimulation.

    “A recent clinical study with two transradial amputees has proven the capability of TIME electrodes in improving sensory feedback when combined with non-invasive somatotopic neural stimulation [99].”

    From Interfaces with the peripheral nervous system for the control of a neuroprosthetic limb: a review (2020) · cites this paper as [99]

    The Abstract reports a study of two transradial amputees implanted with TIME electrodes and receiving somatotopic tactile feedback. However, the Multi-joint proprioception task passage says both sensory streams were delivered through implanted intraneural TIME electrodes, not combined with non-invasive somatotopic neural stimulation. (LLM, conf=0.90)

  • While cuffs have been predominant choice for widespread clinical stimulation applications, newer ultraflexible devices such as TIME are seeing great success in humans.

    “While cuffs have been the predominant choice for widespread clinical stimulation applications, newer ultraflexible devices such as the TIME are seeing great success in humans (D'Anna et al., 2019; Petrini et al., 2019).”

    From Foreign Body Reaction to Implanted Biomaterials and Its Impact in Nerve Neuroprosthetics (2021) · cites this paper as D'Anna et al., 2019

    The Abstract (page unavailable) reports that two human amputees received TIME implants and achieved accurate sensory-feedback task performance, supporting the claim of success in humans. The passages do not establish that cuffs predominate in clinical stimulation or describe TIMEs as ultraflexible. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • Nerve neuroprosthetics offer applications such as control of bladder function, management of depression, and restoration of sensory perception in amputees.

    “Whether by activating nerves through electrical stimulation or by reading their electrical signals, nerve neuroprosthetics offer a myriad of applications such as the control of bladder function (Brindley et al., 1982), management of depression (Nemeroff et al., 2006), and restoration of sensory perception in amputees (D'Anna et al., 2019).”
  • TIMEs coupled with artificial hand prostheses have been used to restore sensory perception in human hand amputee patients.

    “TIMEs are able to both stimulate (Badia et al., 2011b) and record from Badia et al. (2016) separate nerve fascicles within nerves independently, and coupled with artificial hand prostheses have been used to restore sensory perception in human hand amputee patients (Raspopovic et al., 2014; D'Anna et al., 2019).”
  • Together with growing interest in translation of these technologies into human clinical use, FBR has become a dominant problem that needs to be actively addressed at implant design stage.

    “Together with a growing interest in the translation of these technologies into human clinical use (Wendelken et al., 2017; D'Anna et al., 2019; Petrini et al., 2019), FBR has become a dominant problem that needs to be actively addressed at the implant design stage.”

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.
