Biomechanical Assessment and Biofeedback-training System for Handwriting

The purpose of this study is to investigate the real-time kinetics of handwriting regarding the design of the utensil and fine motor performances from biomechanical perspectives. It includes three parts. The first part is an observational study design and the specific aim of the first part of the study is to establish a novel kinetic assessment system incorporated with Force Acquisition Pens (FAPs) designed with different barrel sizes and shapes for handwriting. The thorough calibration, examination of reliability and validity will be presented in this study. The second part is also an observational study design and the specific aim of the second part of the study is to investigate the handwriting mechanisms using the kinetic assessment system incorporated with the motion capture system with children who have writing difficulties. The third part is an interventional study design and the aim of this final part is to integrate the kinetic assessment system and the intervention concept to establish a Biomechanical Assessment and Biofeedback-training System for Handwriting (BABSH). Comparison of the intervention effect of the BABSH and traditional training for the children with handwriting difficulties will also be carried out in this part.
