Description

Place your index finger of your left or right hand on the START circle and follow the dotted line to the GOAL circle as quickly and exactly as possible. The evaluation of the exercise consists of both the speed and the accuracy with which you follow the line. If you have a tablet pen (stylus or touchpen) and specify it when starting the app for the first time, you will regularly be asked to perform an iteration with the pen.

Background

Anatomy

The movements of the hand are the result of a complex interaction of the processing of information. To make a movement, the following steps are performed: First, the information is recorded and then processed into an intended plan. Based on that, the necessary muscle groups are planned, and the movement is precisely coordinated. Finally, the movement performed is compared and verified with the intended target.

Context

The steps mentioned are required in this exercise. Different neurological problems can lead to a decrease in patients’ ability to follow the line. This allows to identify certain neurological problems.
