Eligibility Criteria

Eligible

You may qualify if you...

  • Participants must be 22 years of age or older.
  • Participants must have previously undergone an upper limb amputation proximal to the wrist.
  • For participants without existing RPNI grafts, the residual limb must have enough healthy soft tissue for the RPNI surgery.
  • Participants must be in good health with low surgical risk (ASA Class I or II).
  • Participants must have reliable transportation.
  • Participants must be able to attend at least two visits per month while electrodes are implanted.
  • Participants must be at least 6 months post-amputation.
Not Eligible

You will not qualify if you...

  • Participants with severe pain syndromes like complex regional pain syndrome or severe phantom pain are excluded.
  • Participants with untreated mental health disorders or without approval from a mental health professional if diagnosed are excluded.
  • Participants with medical conditions posing high surgical risk (such as recent heart attack, stroke, blood clots, uncontrolled diabetes, or end stage renal disease) are excluded.
  • Tobacco use within one month before enrollment or during the study is not allowed.
  • Participants with bilateral upper extremity amputation are excluded.
  • Pregnant participants are excluded.
  • Participants with other implanted electronic devices like pacemakers or neurostimulators are excluded.
  • Participants with severe peripheral vascular disease, venous hypertension, or severe lymphedema in the limb are excluded.
  • Participants with poorly controlled autoimmune conditions are excluded.
  • Participants whose amputation is due to traumatic injury or cancer are not considered for enrollment.
