Clinical Trials

Inclusion Criteria:

• The individual can successfully use their prosthesis, list the components used and that their current prosthesis is fitting properly (by performing a tension analysis);
• The individual had unilateral transradial limb loss more than 6 months before the clinical evaluation because, to use a myoelectric prosthesis, the residual limb volume needs to be stable;
• The individual is a proficient owner of one or more common myoelectric prosthetic hands, such as the Sensor Hand Speed and Bebionic.

Exclusion Criteria: 

• Individuals who have had transradial amputation for less than 6 months.
• Individuals who have been fit and trained to use a prosthesis but chose not to use one.
• Individuals who use the i-Limb Quantum myoelectric prosthesis.
• Brachial plexopathy, cervical radiculopathy or polyneuropathy that severely limit upper limb function (observed).
• Orthopedic, joint degeneration (i.e., arthritis, self-reported) affecting the hand or cervical spine that severely limit upper limb function (observed).
• History or concurrently observed age-related neurologic, musculoskeletal, or orthopedic degeneration which would affect study outcomes.
• Visual problems that would interfere with the grasping.
• 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.
• Limited range of motion as assessed through range of motion testing.
• Inability to follow study instructions.
• Use of medications that might affect sensory and/or motor functions.
