Developing a training game for switching between grip patterns in an arm prosthesis.

Testing a serious game developed for learning how to generate myoelectric signals used to switch between different grip patterns of a myoelectrically controlled hand prosthesis and comparing the ability of switching with the ability to proportionally control the signal.

Interventions

This study is set up with a pre- posttest design with a training period in between. During the training all subjects will train with a serious game in a virtual reality setting. This serious game is

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; The time elapsed between start of the first attempt to switch and the completion of the switch, 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. The above described measures will be ranked over participants per test. These ranks will be analyzed.	—

Measure	Time frame
Secondary outcome measures; a. Number of unsuccessful and successful switches. b. Duration of the plateau phase of the aperture of the gripper in the game. c. The difference between the aperture of the virtual gripper and the diameter of three differently sized virtual balls. The above described measures will be ranked over participants per test. These ranks will be analyzed.	—
