This experiment will be executed with healthy subjects. Subjects with (history of) disorders of the arms and/or upper body will not be included. Subject who are experienced with the use of a prosthesis (simulator) will also be excluded.
Conditions
Interventions
During this study all subject will undergo five tests. Two of these tests will be executed with the use of a myoelectric prosthesis simulator. The other three tests will be executed in a virtual envir

Eligibility
Inclusion criteria
Inclusion criteria: The subjects included in this study are able bodied and right handed, with normal or corrected to normal vision. Both male and female subject will be included. All subjects included will be between 18 and 50 years of age.
Exclusion criteria
Exclusion criteria: Subjects with (history of) pain or musculoskeletal impairments of the arms or upper body will not be included. The same accounts for subjects with prior experience in the use of myoelectric devices and subjects younger than 18 or older than 50.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Primary outcome measure per test; 1.Table-top hand; The velocities of the opening and closing of a table-top prosthesis at three different speeds (slow, pleasant and fast). The angle of the regression line through the three velocities will be determined. 2.InterceptPlus; The velocities of the left/right movement of a virtual platform at three different speeds (slow, intermediate and fast). The angle of the regression line through the three velocities will be determined. 3.Cylinder grasp; The difference between the aperture of the hand and the diameter of three differently sized wooden cylinders. The angle of the regression line through the three differences will be determined. 4.BangBang; The difference between the aperture of the virtual gripper and the diameter of three differently sized virtual balls. The angle of the regression line through the three differences will be determined. 5.PEMG; The difference between the asked signal and the produced signal. All of the above described measures will be ranked per test. These ranks will be analyzed. The ranking of the table-top hand will be considered the golden standard. This is the ranking on which the division between HP and LP is based. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary outcome measures; 1. InterceptPlus; a. Scores: related to the accuracy of following a light beam. b. Error margins: difference between asked and delivered velocity. c. Actual speed: actual speed of the platform. | — |
