The instrumented single leg stance test detects early balance impairment in people with multiple sclerosis

Autor: Pål Berg-Hansen, Stine Marit Moen, Thomas Dahl Klyve, Victor Gonzalez, Trine Margrethe Seeberg, Elisabeth Gulowsen Celius, Andreas Austeng, Frédéric Meyer

Publikováno v: Frontiers in Neurology, Vol 14 (2023)

Balance impairment is frequent in people with multiple sclerosis (pwMS) and affects risk of falls and quality of life. By using inertial measurement units (IMUs) on the Single Leg Stance Test (SLS) we aimed to discriminate healthy controls (HC) from

Validation of temporal parameters within the skating sub-techniques when roller skiing on a treadmill, using inertial measurement units.

Autor: Frédéric Meyer, Trine M Seeberg, Jan Kocbach, Jørgen Danielsen, Øyvind Sandbakk, Andreas Austeng

Publikováno v: PLoS ONE, Vol 17, Iss 8, p e0270331 (2022)

The aim of this study was to develop and validate a method using inertial measurements units (IMUs) to determine inner-cycle parameters (e.g., cycle, poles and skis contact, and swing time) and the main sub-techniques (i.e., G2, G3 and G4) in cross-c

Inertial Sensor-Based Estimation of Temporal Events in Skating Sub-Techniques While In-Field Roller Skiing

Autor: Frédéric Meyer, Magne Lund-Hansen, Jan Kocbach, Trine M. Seeberg, Øyvind B. Sandbakk, Andreas Austeng

Publikováno v: Journal of Applied Biomechanics. 39:204-208

The aim of this study was to test and adapt a treadmill-developed method for determination of inner-cycle parameters and sub-technique in cross-country roller ski skating for a field application. The method is based on detecting initial and final gro

Inner-Cycle Phases Can Be Estimated from a Single Inertial Sensor by Long Short-Term Memory Neural Network in Roller-Ski Skating

Autor: Frédéric Meyer, Magne Lund-Hansen, Trine M. Seeberg, Jan Kocbach, Øyvind Sandbakk, Andreas Austeng

Publikováno v: Sensors, Vol 22, Iss 23, p 9267 (2022)

Objective: The aim of this study was to provide a new machine learning method to determine temporal events and inner-cycle parameters (e.g., cycle, pole and ski contact and swing time) in cross-country roller-ski skating on the field, using a single

Point Detection in Ultrasound Using Prewhitening and Multilook Optimization

Autor: Stine Hverven Thon, Roy Edgar Hansen, Andreas Austeng

Publikováno v: IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control. 69:2085-2097

We investigate methods to improve the detection of point scatterers in ultrasound imaging using the standard delay-and-sum (DAS) image as our starting point. An optimized whitening transform can increase the spatial resolution of the image. By splitt

Publikováno v: Øygard, S H, Audoin, M, Austeng, A, Thomsen, E V, Stuart, M B & Jensen, J A 2022, ' Accurate prediction of transmission through a lensed row-column addressed array ', Journal of the Acoustical Society of America, vol. 151, no. 5, pp. 3207-3218 . https://doi.org/10.1121/10.0010528

Using a diverging lens on a row-column array (RCA) can increase the size of its volumetric image and thus significantly improve its clinical value. Here, a ray tracing method is presented to predict the position of the transmitted wave so that it can

Publikováno v: Journal of Neurology

The aim of this work was to determine whether wearable inertial measurement units (IMUs) could detect gait improvements across different disability groups of people with Multiple Sclerosis (pwMS) by the six-minute walk test (6MWT) during a rehabilita

Point detection in textured ultrasound images

Autor: Stine Hverven Thon, Andreas Austeng, Roy Edgar Hansen

Detection of point scatterers in textured ultrasound images can be challenging. This paper investigates how four multilook methods can improve the detection. We analyze many images with known point scatterer locations and randomly textured background
