Sensory Feedback for Touch and Proprioception With Prosthetic Limbs

Upper limb amputation is a devastating injury that leaves many thousands of typically young and active individuals in the US to rely on artificial arms and hands to help restore their lost function. The investigators research is focused on helping these individuals to feel where their prosthetic limbs are moving without having to look at them by developing devices and approaches to provide sensory feedback of limb movement through the nerves that once served the missing limb.

About this study

In the investigators research the investigators seek to understand the organization and (function/operation) of sensory neural systems in order to develop methods for restoring function to injured populations. One of the primary focus areas of the investigators research is working to integrate physiologically relevant sensory feedback with prosthetic limbs. To this end the investigators employ a variety of approaches that interweave disciplines such as electrophysiology, psychophysics, biomedical engineering and cognition. The investigators research team is composed of an interconnected and communicative network of clinicians, engineers, and scientists. This helps us to provide pathways from basic science discoveries that can be used to address clinical needs with transition directly to patient care.

Inclusion criteria

Amputee criteria:

  • Must be over 18 years of age
  • Must be upper extremity amputee who has undergone targeted sensory reinnervation.

Able Bodied participants:

  • Must be over 18 years of age

Treatment and study plan

Tactor array

Device

Bypass Tactor

Device

Primary outcomes

  1. Embodiment of the Prosthetic limb

    Time frame: Ten months

    Visual loading for fine motor tasks,questionnaires, and residual limb temperature will be assessed after 10 months of in home every day use of a custom robust tactor array for sensory feedback.

Secondary outcomes

  1. Investigate the perceptions of limb movement

    Time frame: 6 months

    Test how closely both targeted reinnervation amputees and able bodied study participants are able to interpret limb movement using the kinesthetic perceptual illusion and physiologically relevant kinesthetic feedback.
