Y-Ting Tseng, Sanaz Khosravani, and Arash Mahnan, all graduate students in the Human Sensorimotor Control Laboratory (HSCL), together with their adviser Juergen Konczak, Ph.D., professor and lab director, published in the journal Kinesiology Review. Their review titled “Exercise as Medicine for the Treatment of Brain Dysfunction: Evidence for Cortical Stroke, Cerebellar Ataxia, and Parkinson’s Disease” addresses the role of exercise as an intervention for treating neurological disease. It focuses on three major neurological diseases that either present in acute or neurodegenerative forms—Parkinson’s disease, cerebellar ataxia, and cortical stroke.
The paper is part of a series of invited papers from the National Academy of Kinesiology that appear in Kinesiology Review. Maureen Weiss, Ph.D. serves as the current editor of the journal.
Together with colleagues from Italy and Singapore, Jürgen Konczak, Ph.D., professor in the School of Kinesiology and director of the Human Sensorimotor Control Lab, published a paper that presents a new method to measure proprioception in children. Francesca Marini, a doctoral student at the Italian Institute of Technology, is the first author of the article, “Robot-aided developmental assessment of wrist proprioception in children.“
Neurodevelopmental disorders and brain injuries in children have been associated with proprioceptive dysfunctions that will negatively affect their movements. Unfortunately, the knowledge of how proprioception evolves in typically developing children is still sparse due to the lack of reliable clinical examination protocols.
Jürgen Konczak, Ph.D., professor in the School of Kinesiology, has received an appointment as 2017 Visiting Professor at the Technical University of Munich (TUM).

As part of the professorship, Konczak will join the prestigious TUM Institute of Advanced Studies as an Honorary Fellow and is expected to give lectures to students, faculty and the university community. In addition, he will join the research team of Dr. Hermsdörfer in TUM’s Department of Movement and Health Sciences. The award provides the funds for Dr. Konczak’s stay in Munich and he will join the TUM faculty during the summer months in 2017.
Global sporting goods manufacturer Wilson Sporting Goods Company introduced a new line of high-technology performance tennis rackets that were field-tested in the School of Kinesiology’s Human Sensorimotor Control Laboratory (HSCL) directed by Jürgen Konczak, Ph.D. The participants were experts recruited from the U of M varsity tennis men’s and women’s teams, and testing took place at the U of M Tennis Center.
In tennis, the ball hitting the racket during tennis strokes induces a vibration of the racket frame, which transfers to the arm of the players. High vibration transfer may cause discomfort, induce earlier onset of fatigue and, with repeated exposure, increases injury risk. A racket design that can effectively reduce vibration transfer from the racket to the player’s arm should mitigate these negative vibration effects and aid to stabilize or improve a player’s performance.
Thus Wilson used Countervail technology, a one-of-a-kind layered carbon fiber that was originally designed for the aerospace industry to dissipate vibrational energy in airplanes. Strategic amounts of this material were incorporated into their new Blade performance tennis racket. HSCL measured the vibration in the rackets and determined how much these vibrations transferred to the arm, then compared the vibration behavior of this new design to another commercially available racket. In addition, the electrical signals from several arm muscles were recorded during the play to obtain electrophysiological markers of muscle fatigue.
A main finding of the study is that the new Countervail technology effectively reduces the vibration at the racket, which potentially can help players play longer while maintaining the precision of their strokes.

In collaboration with coworkers from the Italian Institute of Technology and Columbia University, Juergen Konczak, Ph.D., professor in the School of Kinesiology and director of the Human Sensorimotor Control Lab, published a paper entitled “Biofeedback Signals for Robotic Rehabilitation: Assessment of Wrist Muscle Activation Patterns in Healthy Humans” in Transactions on Neural Systems & Rehabilitation Engineering. Marianna Semprini is the first author and Konczak is the senior author.
An excerpt from the abstract: “Electrophysiological recordings from human muscles can serve as control signals for robotic rehabilitation devices. Given that many diseases affecting the human sensorimotor system are associated with abnormal patterns of muscle activation, such biofeedback can optimize human-robot interaction and ultimately enhance motor recovery. To understand how mechanical constraints and forces imposed by a robot affect muscle synergies, we mapped the muscle activity of 7 major arm muscles in healthy individuals performing goal-directed discrete wrist movements constrained by a wrist robot.”
