A simple device to assess and train motor coordination

The purpose of this project was to develop a computer program which can be used on a laptop or other IBM-based computer to assess and train motor coordination in children with closed head trauma or cerebral palsy.

Muscle coordination was assessed by the child's ability to track a series of lines of increasing complexity. A stylus was used by the child to trace lines on a computer screen. Two different line tests were used. In the first, lines of various complexities were drawn on the screen at various angles. The child was asked to trace the line and the accuracy with which the line was traced was determined, providing a score. In a second test, a line was drawn on the screen and the child was asked to trace the line as it was drawn. The error in tracking the line and the time to track the line both were used to evaluate and score the child's performance. Finally, a 'Winnie the Pooh' character was flashed on the screen with distracters such as trees and other animals, and the child was asked to touch the Pooh. By increasing the speed of movement and decreasing the duration that the characters appeared on the screen, the child could be challenged. Successful touching of a character resulted in a positive score.

Six children with cerebral palsy were compared to five children who did not have cerebral palsy, to evaluate the device. While both groups of children showed an increase in motor skills using the program, the increase seen in the children with cerebral palsy was 5-fold greater than that of the control group.

While only a few children were tested with the device, the device seems to prove quite useful for physical and occupational therapy for working on motor skills in children. More investigation is warranted.
