Eligibility | Inclusion Criteria: 1. age > 18 years. 2. no prior experience with the CUFF device. 3. history of elbow disarticulation, transradial, or transhumeral limb loss (non-control subjects only). Exclusion Criteria: 1. amputation for less than 6 months 2. clinical history of brachial plexopathy, cervical radiculopathy or polyneuropathy 3. orthopedic, joint degeneration (i.e., arthritis, verified by x-ray) affecting the hand or cervical spine that severely limit upper limb function 4. visual problems that would interfere with the grasp task 5. co-existing central nervous system disease with symptoms that limit upper extremity function (e.g., multiple sclerosis, motor neuron disease, myasthenia gravis, Parkinson's disease, dystonia) revealed in medical history 6. significant rigidity as assessed through range of motion testing 7. active psychiatric illness 8. significant cognitive impairments (a score < 24 on the Mini-Mental State Examination) 9. use of medications that might affect sensory and/or motor functions 10. inability to effectively control myoelectrics for study purposes (control subjects only) |
