Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Unilateral transradial amputation
  • Amputation occurred 9 months ago or more
  • Functional hand contralateral to the amputation
  • Ability and willingness to use myoelectric arm (as determined by prosthetist)
  • years of age or older
  • Ability to obtain transportation to the research site and the clinicians' offices
  • U.S. citizen or permanent U.S. resident
  • Signed the Informed Consent Form

You may not qualify if:

  • Absence of limb due to birth defect
  • Evidence of denervation of the residual limb
  • Phantom limb pain that is severe enough to impair or restrict activity
  • Any neurological condition affecting motor and/or sensory function that would interfere with use of the intact hand or residual limb (as determined by neurologist)
  • Visual impairment that would affect hand usage during experimental procedures
  • History of chronic infections
  • History of recurring ulcers or blisters on the residual limb
  • Evidence of an active infection, non-healed ulcer, recent history of a healed ulcer (\< 3 months)
  • Use of another implanted electrical device (such as a pacemaker or nerve stimulator)
  • Undergoing diathermy therapy of the residual limb
  • History of non-compliance with medical or research procedures or any condition that would limit their ability to comply with study related procedures (self-reported)
  • Self-reported emotional or psychological disorders or history of drug or alcohol abuse or addiction
  • Memory disorders or significant cognitive impairment (self-reported and/or clinical observation during consent and screening procedures)
  • Moderate to severe chronic pain
  • Pregnant or nursing
  • +3 more criteria
