Efficacy
Confirmatory

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.

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.
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.
There were no adverse events.
