Study Overview
Brief Summary
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.

Arms & Interventions
1st part:System development of Adult
No intervention. Subjects need to use 6 types of special pen to do the specific writing tasks for one hour.
The same tasks will be ask to do again three days later.
1st part:System development of Child
No intervention. Subjects need to use 6 types of special pen to do the specific writing tasks for one hour.
The same tasks will be ask to do again three days later.
2nd part:Handwriting Difficulty
No intervention. Subjects need to do the specific writing tasks and fine motor test for one hour with sensors on the hand. A handwriting screening questionnaire shall be filled.
3rd part: Biofeedback Training
This program includes 1 hour pre-test, 8 times training and 1 hour post-test. For pre-test, subjects need to do the specific writing tasks and fine motor test for one hour. A handwriting screening questionnaire shall be filled.
For post-test, the same procedure will be ask to do again about one and a half month later .
After pre-test, eight times of Biofeedback Training will be asked. Each time will take 50 minutes, one or two times a week. All training will be completed in about one and a half month.
Intervention: Biofeedback Training (Other)
3rd part: Motor Training
This program includes 1 hour pre-test, 8 times training and 1 hour post-test. For pre-test, subjects need to do the specific writing tasks and fine motor test for one hour. A handwriting screening questionnaire shall be filled.
For post-test, the same procedure will be ask to do again about one and a half month later .
After pre-test, eight times of Motor Training will be asked. Each time will take 50 minutes, one or two times a week. All training will be completed in about one and a half month.
Intervention: Motor Training (Other)
3rd part:Control Group
No intervention. Subjects need to do the specific writing tasks and fine motor test for one hour. A handwriting screening questionnaire shall be filled.
The same procedure will be ask to do again about one and a half month later.
Outcomes
Primary Outcomes
Change in the total point score of three subtests of Bruininks-Oseretsky Test of Motor Proficiency, Second Edition (BOT-2)
Time Frame: baseline, 1.5 months
These three subtests are 'fine motor precision (subtest-1) ', 'fine motor integration (subtest-2)' and 'manual dexterity (subtest-3)'. The raw scores of the three subtests were then transformed into point scores based on the BOT-2 manual. The total point scores of the three subtests will be analyzed. For subtest-1, the range of total point score is 0 to 41. For subtest-2, the range of total point score is 0 to 40. For subtest-3, the range of total point score is 0 to 45. Higher total point scores represent a better performance (outcome).
Change in the result of Chinese Handwriting Evaluation Form
Time Frame: baseline, 1.5 months
A questionnaire about handwriting performance. Each item is rated on a five-point ordinal scale
Change in the handwriting kinetic parameters
Time Frame: baseline, 1.5 months
The kinetic parameters designed by measuring the real finger force applied on a force acquisitional pen.
Change in the handwriting kinematic parameters
Time Frame: baseline, 1.5 months
The kinematic parameters designed by measuring the real hand motion using motion analysis system.
Secondary Outcomes
- Change in the pinch force(baseline, 1.5 months)
