Congratulations to Jürgen Konczak, Ph.D., professor in the School of Kinesiology, who received the Marty and Jack Rossmann Faculty Development Award at the College of Education and Human Development assembly on April 30. The Rossmann Award recognizes a tenured faculty member who has demonstrated a truly exceptional level of creativity and productivity in scholarship, teaching and service, and who shows great promise of continuing such achievement. Konzak has instituted and directs the Human Sensorimotor Control Laboratory (HSCL) as well as the Center for Clinical Movement Science (CCMS), an interdisciplinary unit across the University. His research, currently supported by grants from NIH and the NSF, focuses on the study of neurological movement disorders, motor learning after brain injury, and motor development in infancy and childhood and collaborates with, among others, the School of Nursing, School of Veterinary Medicine, College of Engineering as well as with international research centers, primarily in Italy and Singapore. Since joining the faculty in 1999 he has served in leading roles on several Graduate School and College committees and has been the Director of Graduate Studies for the School.

HSC lab publishes in Neuroscience Letters

The Human Sensorimotor Control Laboratory (HSCL) directed by Juergen Konczak, Ph.D., professor in the School of Kinesiology, recently published in the journal Neuroscience Letters. Yu-Ting Tseng, Ph.D. a former lab member of HSCL, is the primary author of the article. Their study, titled “Wrist position sense acuity and its relation to motor dysfunction in children with developmental coordination disorder” is about developmental coordination disorder and examined the relationship of wrist proprioceptive impairment with fine motor and balance function.

Developmental coordination disorder (DCD) is a neurodevelopmental disorder that affects about 6% of school-age children. It is characterized by uncoordinated movements and poor motor skill learning. DCD significantly interferes with a child’s activities of daily living and academic performance. It has long been assumed that impaired body awareness (proprioception) is compromised in children with DCD and that proprioceptive deficits underlie the motor problems in children. This is the second study in a series that objectively assessed proprioceptive status in children with DCD and documents that DCD is indeed associated with a proprioceptive dysfunction, which likely contributes to the motor problems in children with DCD.

Konczak gives talk at CCS Colloquium/Perception Lunch

Jürgen Konczak, Ph.D.professor in the School of Kinesiology and director of the HSC Laboratory, presented at the Center for Cognitive Science (CCS) Colloquium/Perception Lunch Talks on Tuesday, March 27.

The title of Konczak’s talk was “Proprioception – the silent sense: What happens, if it is no longer there?” He illustrated what happens if someone experiences complete or partial loss of proprioception by referring to classic clinical studies and showing data from the lab’s work in patients with dystonia, Parkinson’s disease and cortical stroke.

Konczak publishes with Italian partners in Behavioural Brain Research

Dr. Jürgen Konczak
Dr. Anna Vera Cuppone

Jürgen Konczak, Ph.D., professor in the School of Kinesiology and director of the Human Sensorimotor Control Laboratory (HSCL), has published a paper with colleagues in Behavioural Brain Research. “Consolidation of human somatosensory memory during motor learning” is a collaboration with colleagues from the Italian Institute of Technology. Dr. Anna Vera Cuppone, first author, spent 9 months in HSCL as a visiting scholar, and the data were collected both at HSCL and in Italy.

The main idea behind the paper is to understand how memory is formed during motor learning. Researchers looked at a form of memory related to body awareness, i.e., “how it feels” when the body performs the newly acquired movement patterns. Research in the last years has recognized that such somatosensory and motor learning go hand-in-hand to form “motor memory.” Researchers show how training body awareness improves skill level. The impact of this work relates to neurorehabilitation, because people with stroke that affects the somatosensory cortex, i.e., the part of the brain involved with somatosensory learning, are the most difficult patients to recover. Sensory-based motor learning may help them to recover faster and more completely.

HSC lab publishes first study in 2018 on abnormal muscle activity in horses with shivers disease

In an interdisciplinary collaboration with partners in veterinary medicine at the University of Minnesota and the Michigan State University, researchers in the Human Sensorimotor Control Laboratory examined horses with shivers disease.

An earlier study identified the previously unknown neuropathology of the disease – a degeneration of neurons in the cerebellum. Because the cerebellum is involved in coordinating the control of muscles during movement, the researchers wanted to find out how the loss of cerebellar function affects the muscle recruitment in these horses. Like humans, horses activate more muscle fibers if they want to run faster. However, these horses recruited more muscles and more muscle fibers than necessary, which led to a loss of movement coordination and problems in their balance.

The results of this study, “Abnormal locomotor muscle recruitment activity is present in horses with shivering and Purkinje cell distal axonopathy,” are published in a paper that appears in Equine Veterinary Journal. Joshua Aman, Ph.D., a former postdoctoral researcher in the lab, is the first author of the paper. Other co-authors are current lab member Naveen Elangovan, Ph.D., and Jürgen Konczak, Ph.D.professor in the School of Kinesiology.

Dr. Tseng

Yu-Ting Tseng, Ph.D. (2017), former advisee of Jürgen Konczak, Ph.D., professor in the School of Kinesiology and director of the Human Sensorimotor Control Laboratory, is primary author on an article recently published in Journal of Motor Behavior.  The article is titled “Position Sense Dysfunction Affects Proximal and Distal Arm Joints in Children with Developmental Coordination Disorder. ”
Co-authors are Chia-Liang Tsai (National Cheng Kung Univeristy, Taiwan,), Fu-Chen Chen (National Kaohsiung Normal University, Taiwan), and Jürgen Konczak.

Developmental coordination disorder (DCD) is a neurodevelopmental disorder that affects up to 6% of all school-age children. Children with DCD have problems with coordinating  movements, may have balance problems and show poor motor skill learning. This study assessed wrist joint position sense in a cohort of Taiwanese middle school children with DCD and related it to the observable motor deficits. Results document that children with DCD is associated with proprioceptive dysfunction of the wrist/hand complex, which likely contributes to the motor problems in children with DCD.

Yu-ting Tseng is currently a post-doc at the Division of Child Health Research, Institute of Population Health Sciences in the National Health Research Institutes (NHRI) in Zhunan, Taiwan.

NIH awards grant to Konczak lab to develop technology for treating a voice disorder

Jürgen Konczak, Ph.D.
Arash Mahnan, Ph.D. student

Jürgen Konczak, Ph.D., professor in the School of Kinesiology is the principal investigator on an NIH funded grant program administered through the University’s Office of Discovery and Translation that seeks to promote new therapies for rare diseases. The project will design and build a device that will improve the symptoms of a voice disorder called spasmodic dysphonia (SD).

People with SD experience involuntary spasms of the laryngeal musculature that leads to a strained or choked speech. There is no cure for the disease and speech therapy is ineffective. The device will alter how it feels when one speaks. The idea behind the technology is that this sensory trick will help patients to improve their voice quality.  The device development and its testing will be conducted in Konczak’s Human Sensorimotor Control Laboratory.

Arash Mahnan, biomedical engineer and doctoral student in the HSC lab will serve as primary research assistant for this project.
