Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Pre- and post-training results of the speed of motor-execution with non-dominant hand and its change from pre-assessment to post-assessment, and Asymmetric values of the speed of motor-execution with non-dominant and dominant hand and its change from pre-assessment to post-assessment. *Post-training assessment timing sets at the end of 6 week- training. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Pre- and post-training results of the smoothness of upper extremity (root mean square of angular jerk; RMSJ) with non-dominant hand and its change from pre-assessment to post-assessment. 2. Pre- and post-training results of the brain activity (oxygen-hemoglobin concentration; Oxy-Hb concentration) during task performance with non-dominant hand in each channel or regions of interest (ROIs) and its change from pre-assessment to post-assessment. 3. Pre- and post-training results of the brain activity (Oxy-Hb concentration) during task performance with non-dominant hand in each hemisphere and its change from pre-assessment to post-assessment. 4. Pre- and post-training results of the visual analog scale(VAS) as perceived psychological stress with non-dominant hand and its change from pre-assessment to post-assessment. 5. Pre- and post-training results of the speed of motor-execution with dominant hand and its change from pre-assessment to post-assessment. 6. Pre- and post-training results of the smoothness of upper extremity (RMSJ) with dominant hand and its change from pre-assessment to post-assessment. 7. Pre- and post-training results of the brain activity (Oxy-Hb concentration) during task performance with dominant hand in each channel or ROIs and its change from pre-assessment to post-assessment. 8. Pre- and post-training results of the brain activity (Oxy-Hb concentration) during task performance with dominant hand in each hemisphere and its change from pre-assessment to post-assessment. 9. Pre- and post-training results of the VAS as perceived psychological stress with dominant hand and its change from pre-assessment to post-assessment. 10. Asymmetric values of the smoothness of upper extremity (RMSJ) with non-dominant and dominant hand and its change from pre-assessment to post-assessment. 11.
