  1. 1. Nonlinear Modeling and Feedback Control of Drug Delivery in Anesthesia

    Author : Margarida M. Silva; Alexander Medvedev; Teresa Mendonça; Torbjörn Wigren; Robain De Keyser; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; anesthesia; drug delivery; feedback control; nonlinear modeling; pharmacokinetics pharmacodynamics; PID control; system identification; Wiener model; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Abstract : General anesthesia is a drug-induced reversible state where neuromuscular blockade (NMB), hypnosis, and analgesia (jointly denoted by depth of anesthesia - DoA) are guaranteed. This thesis concerns mathematical modeling and feedback control of the effect of the muscle relaxants atracurium and rocuronium, the hypnotic propofol, and the analgesic remifentanil. READ MORE

  2. 2. Inertial motion capture for ambulatory analysis of human movement and balance

    Author : Fredrik Olsson; Kjartan Halvorsen; Peter H. Veltink; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inertial sensors; Human motion capture; Calibration; Neuromuscular control; Human balance; Tremor quantification;

    Abstract : Inertial sensors (accelerometers and gyroscopes) are ubiquitous in today’s society, where they can be found in many of our everyday mobile devices. These sensors are capable of recording the movement of the device, and by extension, the movement of humans carrying or interacting with the device. READ MORE

  3. 3. Spatio-temporal processing of surface electromyographic signals : information on neuromuscular function and control

    Author : Christer Grönlund; Leif Sörnmo; Umeå universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; EMG; multichannel surface electromyography; motor unit action potentials; conduction velocity; muscle architecture; signal quality; spatial distributions; synchronization; muscle function; motor control; biomedicinsk strålningsvetenskap; Biomedical Radiation Science;

    Abstract : During muscle contraction, electrical signals are generated by the muscle cells. The analysis of those signals is called electromyography (EMG). The EMG signal is mainly determined by physiological factors including so called central factors (central nervous system origin) and peripheral factors (muscle tissue origin). READ MORE

  4. 4. Altered movement patterns and deviating muscular activity in individuals with anterior cruciate ligament injury

    Author : Anna Trulsson; Fysioterapi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Movement pattern; Physiotherapy; Motor control; Sensorimotor control; Neuromuscular control; Anterior cruciate ligament; Muscular activity; Motor skills; Single leg squat; Electromyography EMG ; Postural orientation; Assessment; Task performance; Reproducibility of findings; Performance test; Hop test; knee; dynamic joint stability;

    Abstract : The purpose of this thesis was to increase the understanding of altered movement patterns in individuals with anterior cruciate ligament (ACL) injury in order to improve ACL rehabilitation, and to develop an observational instrument termed Test for Substitution Patterns (TSP) for standardized, quantifiable scoring of altered movement patterns in legs and trunk. In all, 142 participants, 93 with ACL-rupture (37 women) and 49 uninjured participants were investigated. READ MORE

  5. 5. Modelling driver steering and neuromuscular behaviour

    Author : Ola Benderius; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; MEDICIN OCH HÄLSOVETENSKAP; ENGINEERING AND TECHNOLOGY; MEDICAL AND HEALTH SCIENCES; reaching; neuromuscular behaviours; lateral control; driver models; Driver behaviours; active safety; autonomous vehicles;

    Abstract : This thesis challenges the traditional view of treating steering behaviour as a tracking task, instead treating it as a reaching task. Here, reaching refers to a fundamental human behaviour with the the intriguing characteristic of having a linear relationship between maximum speed and distance, effectively making the movement time constant.
