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 a unilateral transradial amputation 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 current user of one of two common myoelectric prosthetic hands: Sensor Hand Speed and Bebionic (both Ottobock).

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;
• clinical history of brachial plexopathy, cervical radiculopathy or polyneuropathy;
• orthopedic, joint degeneration (i.e., arthritis, self-reported) affecting the hand or cervical spine that severely limit upper limb function (observed);
• 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.
