My Scrivener® - Measuring Effectiveness and Dose Response in Children

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00919906

Brief Summary:
This study will assess whether a computer haptic peripheral device programmed to provide repetitive motion training is as effective as the same repetitive motion training provided by a human being.

Asperger's Syndrome Dyslexia Cerebral Palsy Attention Deficit Disorder ADHD Traumatic Brain Injury Stroke Device: My Scrivener(R) Phase 1 Phase 2

Detailed Description:

This study builds on a large body of neurological research that uses robot-guided repetitive motion training to induce neuroplasticity and improvements in upper extremity motor skills in adults and children. This research study is looking at handwriting, a fine-motor task that is used daily.

In our study, we want to see if 3-dimensional robotic-assisted repetitive motion training can be a safe and effective intervention for school-age children with fine motor deficits arising from several different impairment origins. Our research construct is: Legible handwriting = function of (tactile feedback, visual feedback, duration, and fine-motor control).

Independent variables:

  • Tactile feedback is a continuous variable of force-feedback measured in pounds of force.
  • Duration is a continuous variable measured in seconds and number of repetitions.
  • Visual feedback is the letter scribed on the paper.

Dependent variable:

  • Legible handwriting will be measured by scoring on the Test of Handwriting Skills and the Print Tool™ evaluation.
  • Fine motor deficit/control will be measured directly and objectively by quantifying the error between the desired scribing task and the actual scribing task.

The robotic device is an affordable (<$200) computer haptic (the Falcon(R)) that currently is approved by the FCC for home and office. It is *not* approved for medical use. This is an investigational, nonsignificant risk device.
