A robotic arm is lending a hand to children with dyspraxia, a motor-skills deficit also known as Developmental Coordination Disorder or Clumsy Child Syndrome.
The arm, under development at the U.K.’s University of Leeds, lets children with coordination problems practice therapist-prescribed exercises at home using an interactive desktop system. The system can also monitor how the kids move, measuring factors like smoothness, speed of movement, and joint configurations.

Guided by the robotic arm, for example, kids use a pen to push objects along a 3D track displayed on a computer screen. The system applies guiding forces to the child’s arm and hand to help control movements. The strength of the forces can be altered to shape movements and vary the difficulty of the exercises.
“We originally started with a hospital-based system, but our user group of children said they’d much prefer to be able to use it at home after school, so we adapted it to a more suitable laptop-based system that fits inside a small holdall,” said Mark Mon-Williams, a University of Leeds professor of cognitive psychology who is leading the research, in a statement. “They also got involved in the design of the games and exercises.”
The Leeds team is collaborating with researchers at universities in Aberdeen, Scotland, and Indiana, with funding from U.K. children’s health charity Action Medical Research.
Dyspraxia is a neurologically based disorder that affects the ability to see a movement goal through to completion. Children with dyspraxia struggle with skillful, controlled actions, making simple, daily tasks such as buttoning their coats more difficult. Handwriting often suffers, which can lead to homework struggles and ultimately a loss of self-confidence.
