Brief Summary

Inducing a systematic perturbation forces on the hand during arm reaching movement may improve adaptation. Error-augmentation (EA) training is relatively new concept in motor learning intended to promote the adaptation process. In this study participants will practice one session of training on 3D robotic device. Healthy volunteers will be randomly divided into two groups: study and control. The study group will carry out the training session with EA forces. The control group will carry out the same procedure with null force field. Outcome measure are the average size of trajectory error from the straight line and level of exertion (borg scale).

Conditions

Healthy Volunteers

Outcome Measures

Primary Outcomes (1)

• Change in average movement error from baseline

  Average size of trajectory error form the straight line while making arm reaching movement

  At baseline, before the beginning of the training session, and at followup measurement immediately at the the end of the training session, which is about 45 minutes after the first evaluation.

Secondary Outcomes (1)

• Change in Borg scale score from baseline

  At baseline, before the beginning of the training session, and at followup measurement immediately at the end of the training session, which is about 45 minutes after the first evaluation.

Study Arms (2)

Error enhancement

EXPERIMENTAL

Arm reaching rehabilitation training with error-augmentation perturbation forces. One session of about 25 minutes of practicing arm reaching movements on 3D robotic device.

Other: Error enhancement

Control group

OTHER

Arm reaching rehabilitation training without error-augmentation perturbation forces. One session of about 25 minutes of practicing arm reaching movements on 3D robotic device.

Other: Control group

Interventions

Error enhancement OTHER

Participants will sit in front of a 3D robotic device and grab the robotic arm handle. The participants will carry out arm reaching tasks appear on a screen on front of them. Each game of tasks will lasts 2 minutes. The participants will carry out one game to be accustomed to device, followed by one game with null force field, followed by 5 games as the main intervention with error enhancement force field, and another last game with null force field.

Error enhancement

Control group OTHER

Participants will sit in front of a 3D robotic device and grab the robotic arm handle. The participants will carry out arm reaching tasks appear on a screen on front of them. Each game of tasks will lasts 2 minutes. The participants will carry out one game to be accustomed to device and another 7 games with null force field.

Control group
