On Tuesday, 24 September, we will organise four hands-on workshops in which attendants can learn more about the background and practical use of advanced measurement technologies related to movement analysis.
Each workshop session will have a maximum of 20 participants, to ensure the hands-on character. Depending on the number of participants, the workshops will be held in the morning and/or afternoon session. Please note that participants could be redistributed between morning and afternoon sessions, depending on the number of registrations per session. Participants will be notified in advance if this is the case.
Ultrasound is a popular imaging technique for in vivo study of the musculoskeletal (MSK) system. It can be used to diagnose and assess MSK injury, including fractures, muscle and tendon strains, but also judge structural changes due to neuromuscular disorders through analysis of morphology and echointensity. For example, in static conditions, 3D MSK ultrasound technology offers a means to accurately estimate a muscles’ volume, or muscle, fascicle and tendon lengths. In dynamic conditions, ultrasound can be used to describe the active and passive properties of muscle and tendon, providing motion analysists the opportunity to investigate muscle/tendon interaction during joint movement (e.g. during gait). Therefore, with an ever-increasing number of applications, MSK ultrasound imaging is an appealing and relatively inexpensive tool for clinicians and movement scientists to integrate into their clinical research providing valuable information on MSK function in typical and pathological movement.
In this hands-on workshop, we will demonstrate three applications of MSK ultrasound imaging for clinical research, with focus on the lower-leg and ankle. Participants will have the opportunity to collect and process data and if interested, take their acquired images home for further exploration.
Three hands-on stations will be offered, followed by a discussion of clinical case studies:
Bipedal human gait has evolved as a very energy efficient way of locomotion. Our gait pattern is tuned to minimize metabolic energy cost and we typically select gait speed that allows us to cover a distance with minimal energy requirements and that can be endured for a long time. In patients with gait pathologies energy cost of walking is often substantially increased. Moreover, the metabolic capacity can be substantially reduced. This can result in early fatigue and limited walking distance of these patients.
Analysis of metabolic demand of gait and metabolic capacity of patients can provide important insight in functional limitations of patients and underlying impairments. To what extend is limited walking distance and fatigue related to increased metabolic cost, reduced metabolic capacity or both? Such analysis can guide clinical interventions aimed at reducing energy cost or increasing capacity.
In this workshop you will learn which metabolic pathways provide energy for walking and how they can be affected in patients. You’ll learn and practice how to measure maximal aerobic capacity of patients and energy cost during walking using respirometry. Finally, you learn how to interpret the outcomes of these test and draw clinical conclusions and plan potential interventions.
Virtual Reality (VR) and Augmented Reality (AR) have been around for decades, but now these techniques are used more and more in rehabilitation. Using VR or AR enables us to assess and train walking abilities in personalized challenging environments in a safe manner. Two examples shown in this workshop are 1) Interactive Walkway (IWW), a multi-Kinect-v2 instrumented 10m walkway with 2D visual context, and 2) the Gait Real-time Analysis Interactive Lab (GRAIL), an instrumented treadmill embedded in a semi-cylindrical virtual environment with real-time motion capture . These systems allow for a comprehensive assessment and training of walking ability, possibly leading to a better understanding, evaluation and ultimately improvement of walking-related parameters.
This hands-on workshop will give you the chance to get familiar with the basic principles and benefits of interactive gait analyses through lecture-like plenary presentations intermingled with demos of the GRAIL and IWW, including a demo of the Microsoft HoloLens. Furthermore, attendees are offered hands-on experience with interactive gait analyses through two different interactive demos in smaller rotating groups: 1) AR overground walking (IWW demo) and 2) AR treadmill walking (GRAIL demo).
Get your own plantar pressure distribution! This hands-on seminar will focus on the background, use, and implementation of plantar pressure measurements in clinical care. Next to some technical background, participants will be able to measure their own plantar pressure distribution and learn how these measurements are applied in the clinical care of several patient groups, including diabetic feet, cerebral palsy and other neurological and orthopedic foot problems.
