Lead Sponsor
National Cheng-Kung University Hospital
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.

GroupInterventionDescription
3rd part: Motor TrainingMotor TrainingThis 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.
3rd part: Biofeedback TrainingBiofeedback TrainingThis 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.
Primary Outcome Measures
NameTimeMethod
Change in the total point score of three subtests of Bruininks-Oseretsky Test of Motor Proficiency, Second Edition (BOT-2)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 Formbaseline, 1.5 months

A questionnaire about handwriting performance. Each item is rated on a five-point ordinal scale

Change in the handwriting kinetic parametersbaseline, 1.5 months

The kinetic parameters designed by measuring the real finger force applied on a force acquisitional pen.

Change in the handwriting kinematic parametersbaseline, 1.5 months

The kinematic parameters designed by measuring the real hand motion using motion analysis system.

Secondary Outcome Measures
NameTimeMethod
Change in the pinch forcebaseline, 1.5 months

three types of pinch force were recorded by a pinch meter
