A Look Inside the Treatment Room: How Lucas Learned to Write with Robot-Guided Games
A detailed case study about the therapeutic journey of an 8-year-old boy with DCD, and the role of advanced robotics in his progress.

Lucas, a lively 8-year-old, came to us with a diagnosis of Developmental Coordination Disorder (DCD). His biggest frustration? He couldn't write his name legibly, which led to a lot of insecurity at school. His pediatric physiotherapist started a course of treatment with our RoboGuide system.
The Approach: From Grip to Movement
The treatment didn't start with writing itself, but with the basics: the pencil grip. Our system uses an adapted stylus connected to a robotic arm. During the first sessions, the robot subtly guided Lucas's hand to the correct tripod grip.
The magic lies in the haptic feedback. If Lucas applied too much force, the handle would vibrate gently. If he pulled the pen at an angle, the robot provided light, corrective resistance. All of this happened within the context of a game called 'Astro-Drawing', where he had to follow lines to fuel a rocket.
Key Figures from this Case
- Duration of treatment: 12 weeks, 2 sessions per week.
- Improvement in pencil grip stability: 68% (measured via pressure sensors).
- Increase in writing speed: From 2 to 8 letters per minute.
- Self-confidence (parent report): "He now picks up a pencil on his own."
The Breakthrough: Gamification as a Motivator
What made the difference for Lucas was the immediate, visual reward in the game. For every successful movement, he earned points and saw his rocket fly further. The therapist could adjust the parameters in real-time, allowing the exercise to grow with his skills. The frustration of practice gave way to the challenge of the game.
After 6 weeks, the focus shifted to forming letters. The robot now assisted with the specific movement patterns for the letters L, U, C, A, and S. The hand-eye coordination improved visibly, not only in the game but also in other tasks like cutting and tying shoelaces.

Conclusion and Future Outlook
The case of Lucas underscores that robot-guided intervention is a powerful addition to traditional pediatric physiotherapy. It provides consistent, measurable, and above all, motivating support for complex motor learning processes. For Lucas, the journey wasn't over yet, but he could finally write his name in his notebook with pride.
This technology doesn't sideline therapists, but rather gives them a detailed instrument in their hands. The next step in our research is to measure the longitudinal effect on general school participation.
