The 'zwabbervoet': the nightmare of every skater
On the 2nd of February Beorn Nijenhuis, a former Olympic speedskater and current PhD student at Movement Disorders Groningen, was a guest on the NPO2 program ATLAS. There he got to explain his research on ‘zwabbervoet’, a mysterious movement disorder that affects famous speedskaters like Gerard Kemkers and Marianne Timmer.
It is a well-known story among older skating fans: 23 year old Olympian Gerard Kemkers had his skating career cut short by a mysterious problem with his foot called zwabbervoet. Physiotherapists and doctors were all at a loss to help him, and so he had to quit. For many years the mystery of zwabbervoet went unsolved, however now thanks to Marina de Koning-Tijssen and the team at Movement Disorders Groningen the mystery might be solved.
Zwabbervoet is likely a task specific movement disorder, whose origin is in the brain. Part of the evidence for this was presented on the NPO2 program: ATLAS. Here, Beorn Nijenhuis explained how the Movement Disorders team has found evidence of ‘coherence’ in muscles of skaters with zwabbervoet, a common sign of task specific dystonia. This research is an important step in better understanding zwabbervoet, and helping skaters who suffer from the problem.
