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 part; Serious game: Proportional: the error between required and produced velocity and the difference between the aperture of the virtual gripper and the diameter of three differently sized virtual balls. Discrete: Number of unsuccessful and successful switches, time needed to produce switch, and the type of command signal used to switch (hold-open, co-contraction, double puls). Displayed EMG signal: Proportional: 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. Discrete: Number of unsuccessful and successful switches. Time needed to produce switch. Prosthesis task: Duration of correctly re-placing a set of 6 clothespins. Primary outcome measure for pre- and posttest; Duration of correctly re-placing a set of 6 clothespins. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary outcome measures; Serious game: Proportional: Duration of the plateau phase of the aperture of the gripper in the game. Accuracy of catching. Number of broken/missed/bounced objects. Discrete: x Displayed EMG signal: Proportional: x Discrete: time needed to produce switch. Prosthesis task: Proportional: Plateau time of hand opening Discrete: Number of unsuccessful and successful switches. All the above described measures will be ranked over participants per test. These ranks will be analyzed. | — |
