A Study to Assess Force Feedback with the SoftHand Pro

Overview

About this study

The purpose of this study is to test the effectiveness of the CUFF device in combination with the Soft Hand Pro (SHP) in conveying haptic force feedback to patients with upper extremity limb loss, and to assess the extent to which the grip force feedback improves the embodiment of the prosthetic device.

 

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate.

Exclusion Criteria: 

  • Amputation for less than 6 months.
  • Clinical history of brachial plexopathy, cervical radiculopathy or polyneuropathy.
  • Orthopedic, joint degeneration (i.e., arthritis, verified by x-ray) affecting the hand or cervical spine that severely limit upper limb function.
  • Visual problems that would interfere with the grasp task.
  • 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.
  • Significant rigidity as assessed through range of motion testing.
  • Active psychiatric illness.
  • Significant cognitive impairments (a score < 24 on the Mini-Mental State Examination; non-control subjects only).
