Keynote Speakers

Jason M. Wilken

Jason Wilken PT, PhD is an Associate Professor and Director of Collaborative Research and Development in the Department of Physical Therapy and Rehabilitation Science at the University of Iowa. He also serves as the Director of the Human Performance and Clinical Outcomes laboratory. Prior to joining the University of Iowa, he was the founding Director of the Military Performance Laboratory at the Center for the Intrepid at Brooke Army Medical Center and Senior Scientist for the Extremity Trauma and Amputation Center of Excellence. His patient centric research is focused on maximizing function after lower limb injury or disease. His efforts include the development and evaluation of advanced prosthetic and orthotic technologies, virtual reality-based interventions, clinically relevant outcomes assessment, and development of novel approaches to enhance walking stability.

Where are the disagreements? From clinical opinion to scientific evidence.

This presentation will highlight the use of clinical insights and differences in opinion to advance prosthetic and orthotic related care. The session will outline a pragmatic and mechanistic approach to interpretation of clinical data in the context of data quality metrics, discuss barriers to adoption of novel prosthetic and orthotic technologies, and highlight efforts to develop evidence-based guidelines for the prescription and provision of orthoses.

Tron Krosshaug

Tron Krosshaug, PhD is a professor at the Oslo Sports Trauma Research Center and the Department of Sports Medicine at the Norwegian School of Sport Sciences. His main research area is sports injury prevention, with a primary focus on biomechanical analysis of serious knee injuries in various sports. In his PhD work he developed a new method for extracting 3D joint kinematics from videos of real injury situations. The method has later been used by researchers world-wide to investigate e.g. ankle sprains and head impacts in various sports.

Moreover, Krosshaug has utilized 3D movement analysis in experimental biomechanical studies as well as in prospective cohort studies, to increase our understanding of ACL injury etiology. Krosshaug is also an entrepreneur with his company Muscle Animations where the aim is to be world leading in 3D visualization and dissemination of evidence-based knowledge about strength training biomechanics, exercise technique and muscle-skeletal loading.

Using motion analysis to understand injury mechanisms and biomechanical risk factors for Anterior Cruciate Injury. A travel from year 2000 into the future

This lecture describes our journey using various motion analysis technologies to understand injury mechanisms and biomechanical risk factors for Anterior Cruciate Ligament (ACL) injuries. Part 1 discusses how the challenge of analyzing ACL injuries led to the development and validation of a Model-Based Image-Matching method, providing insights into the essential mechanism of ACL ruptures. Part 2 presents a seven-year prospective cohort study involving 880 elite Norwegian female athletes, revealing cutting maneuvers and knee abduction moments as key risk factors for future injury. In Part 3, we explore how cutting technique remains consistent across task complexity, highlighting potential for risk reduction by targeting individual technique. Part 4 introduces a novel

software developed for immediate feedback on joint loading and cutting techniques, demonstrating its effectiveness in enabling handball players to reduce knee abduction loading without compromising cutting effectiveness. Finally, Part 5 discusses the future of ACL risk assessment, focusing on the potential of computer vision and markerless motion capture to offer individual assessment, training, and feedback using movement analysis.

Reidun Birgitta Jahnsen

In addition to being professor emerita at the Institute of Health and Society, Department for Public Health Science and Epidemiology, University of Oslo, Reidun Birgitta Jahnsen holds the following positions: Senior researcher in the Norwegian Quality and Surveillance Registry for Cerebral Palsy (NorCP) at the Department of Pediatric and Adolescent Medicine, Oslo University Hospital www.norcp/ and a Senior researcher at Beitostølen Healthsports Centre

Her background is more than 20 years of clinical physiotherapy work, and even longer of research. Since 1997, her main position has been at Oslo University Hospital (OUH), from 2006 in NorCP. This position has included both clinical work in the Motion Laboratory and research, and from 2010 only research, shared between OUH and Beitostølen Healthsports Centre (BHC), a publicly funded rehabilitation centre in the Norwegian mountains. BHC is a world leader in the field of combining adapted physical activity with rehabilitation medicine, and collaboration with NTNU in Trondheim allows us to do 3D motion analysis out in the field.

For most of her professional life, her interest has been habilitation and rehabilitation in a life-course perspective. As physiotherapist, her focus has been Human Movement Science. In clinical work and in research, this interest has been both participation at various life arenas, including adapted physical activity, and detailed technological analysis of the movements and the forces and dynamic systems that govern them. She has been a supervisor of several PhD and master projects, six for the time being, that apply both quantitative and qualitative research methods, from participant observation, individual interviews and focus group interviews to randomized controlled trials, methodological studies, and registry research.

Movement is a living thing

One thing is, loving to move, another to become a professor of others moving – borrowing Soren Kierkegård’s quote: One thing is to suffer, another to become a professor of someone else suffering.

This lecture will deal with the concept of Human Movement Science: from practice to research and return – and from practice to theory and return – from loving to dance to 3D motion analysis of international folk dance – and from there to 3D gait analysis of children with cerebral palsy. It will

deal with movement as a prerequisite and potential for activity and participation – movement as a problem – and movement as an intervention for goal attainment. Using the ICF perspective – all the body-functions and -structures are prerequisites for activity and participation in interaction with the environment – emphasising participation as a means and an end.

The lecture will draw upon Nicolai Bernstein (1896-1966), the Russian neurophysiologist who represented a paradigm shift in the understanding of human movement – from reactive to active. The purpose was to optimize productivity of Russian industry, and he used cyclographic techniques to track human movement in many experiments. His research showed that most movements, like hitting a chisel with a hammer, are composed of smaller movements, and any one of these smaller movements, if altered, affect the movement. However, the consequence was that stimulus response (Pavlov) was replaced by a cyclic dynamic systems theory where movement and consciousness are interacting in an open developmental spiral. This became too much for the authorities, and his book, “The regulation and coordination of movement” (1967) was suspended and forbidden. How did it end up in Norway? That’s the cliffhanger…..
