    Author : Marie Lund Ohlsson; Marko Laaksonen; Jonas Danvind; L. Joakim Holmberg; Anders Eriksson; Mittuniversitetet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; blood lactate concentration; cross-country sit-skiing; impairment; internal kinetics; inverse dynamics simulations; joint reaction forces; kinematics; metabolic rate; musculoskeletal modelling; musculoskeletal efficiency; nordic skiing; oxygen uptake; para-skiing; respiration; skiing efficiency.;

    Abstract : Double poling (DP) is a sub-technique in cross-country skiing that has increased in interest over the last decades, e.g. athletes in cross-country skiing have increased their utilisation of double poling during competitions. READ MORE

  4. 22. Musculoskeletal disorders in Swedish military aircrew : screening and clinical examination of the cervico-thoracic region

    Author : Matthias Tegern; Ulrika Aasa; Björn Äng; Karin Harms-Ringdahl; Mari Lundberg; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Musculoskeletal disorders; Pain; Swedish Armed Forces; aircrew; pilots; physiotherapy; reliability; sjukgymnastik; Physiotherapy;

    Abstract : Musculoskeletal disorders (MSD) are a common and growing occupational problem in military aircrew. Intervention studies attempting to reduce such issues have only showed limited preventive effects. Furthermore, in-depth knowledge of the clinical presentation of aircrew members with painful episodes is lacking. READ MORE

  5. 23. On the Utility of Representation Learning Algorithms for Myoelectric Interfacing

    Author : Alexander Olsson; Avdelningen för Biomedicinsk teknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EMG; Machine Learning; Deep Learning; Feature Learning; Biosignal Processing; Gesture Recognition; Muscle-Computer Interfaces; Myoelectric Control; Upper-Limb Prosthetics;

    Abstract : Electrical activity produced by muscles during voluntary movement is a reflection of the firing patterns of relevant motor neurons and, by extension, the latent motor intent driving the movement. Once transduced via electromyography (EMG) and converted into digital form, this activity can be processed to provide an estimate of the original motor intent and is as such a feasible basis for non-invasive efferent neural interfacing.

  6. 24. Biomechanical Parameter Estimation for Wearable Exoskeleton System Design

    Author : Longbin Zhang; Elena Gutierrez Farewik; Ruoli Wang; Christian Smith; Max Ortiz Catalan; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hill-type muscle model; generalization; transfer learning; computationally modeling; human-machine system; Engineering Mechanics; Teknisk mekanik;

    Abstract : Exoskeletons are increasingly used in rehabilitation and daily life in persons with motor disorders after neurological injuries. The overall objective of this thesis is to study how to robustly and accurately predict joint torque using inputs from sensors that would technically be feasible to equip on an assistive exoskeleton, and to develop a framework that could be used to evaluate the user-exoskeleton interface.

  7. 25. Neck pain in air force pilots : on risk factors, neck motor function and an exercise intervention

    Author : Björn Äng; Karolinska Institutet; Karolinska Institutet; []
    Keywords : biomechanics; cervical pain; electromyography; military pilots; movement quality; muscle fatigue; muscle strength; neuromuscular; physiotherapy; range of motion;

    Abstract : Neck pain is a medical problem in modern military aviation. While neck exercises are recommended, clinical trials of neck motor function have been less investigated. READ MORE
