Jürgen Konczak, Director of the Human Sensorimotor Control Laboratory, gave a presentation to the International Congress of Clinical Neurophysiology 2026 in Cartagena, Columbia. As part of a symposium that focused on dystonia as a network disease, Konczak spoke on how we get from identifying biomarkers to targeted therapies for focal dystonia. Specifically, he presented the lab's research on using vibro-tactile stimulation as a non-invasive neuromodulation treatment for focal dystonia.
Jürgen Konczak, Director HSCL, published a study with colleagues in otolaryngology in the specialty journal Laryngoscope on acoustic markers associated with the voice disorder laryngeal dystonia. This form of focal dystonia is a chronic voice disorder without a cure and regular injections of Botulinum toxin is the major available treatment. This study examined whether several acoustic markers of voice can be good candidates to determine changes in voice quality due to Botulinum toxin treatment. The open access study found that these markers correlate with certain speech symptoms, but are not meaningful predictors of a treatment response. The lead author of the study is Dr. Jesse Hoffmeister from the UM Department of Otolaryngology.
Jürgen Konczak, Director of HSCL, is coauthor of a new publication in the journal Brain Sciences. The publication entitled Effects of Temporal Expectancy on Motor Control and Cognitive Processes Supporting Speech Production results from a collaboration with the lab of Dr. Jayanthi Sasisekaran from the Department in Speech, Language and Hearing Sciences. Using electroencephalography, the study investigated the responses of brain regions involved in speech production. The goal was to understand how cognitive processes affected speech production. The results show that temporal predictability primes speech motor planning and enables faster speech, extra cognitive demands delayed speech onset in healthy adult speakers.
Jürgen Konczak, Director of the HSC Lab, gave a series of online eight lectures at the University of Genoa to graduate students in the Fisioterapia Neurologica (neurological physical therapy) program. The lectures covered the basic neurophysiology of proprioception and its role for the control of movement as well as examples of neurological movement disorders associated with proprioceptive dysfunction.
Jürgen Konczak gave a talk at the Canadian Stroke Congress in Banff, a town in the Canadian Rockies. He spoke at a symposium on cerebellar stroke and presented research of his lab and his German collaborators from the Essen University Medical Center on what are good neurophysiological and neuroanatomical predictors of recovery after cerebellar stroke or tumor resection. The symposium was attended by over 200 professionals involved in acute stroke care and rehabilitation such as neurologists specializing in stroke, physiatrists, occupational and physical therapists.
