Assessment

Primary outcomes

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.

Key secondary outcomes

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. Asymmetric values of the VAS as perceived psychological stress w with non-dominant and dominant hand and its change from pre-assessment to post-assessment.

Results

After 6 week-training, significantly improved chopstick performance were observed in the training group. Moreover, left dorsolateral prefrontal cortex activity significantly decreased, and bilateral premotor cortex activity significantly increased across training.
*The results have already been published in the journal.

All asymmetric values were significantly lower in the training than in the control group at post-training assessment. *These results will be submitted for publication.

Baseline Characteristics

Thirty-four healthy right-handed participants were recruited in this study (17 women; mean age, 21.3(0.7) years) were recruited. Stratified randomization was used to allocate each participant to either the training group or the control group by a researcher who was neither an evaluator nor a trainer.

Participant flow

One participant from the training group failed to complete the program, and one from the control group was unable to accomplish the re-assessment. Thus, 16 participants each were included in the training and control groups.

Adverse events

There were no adverse events.
