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

    Author : Fredrik Olsson; Kjartan Halvorsen; Peter H. Veltink; Uppsala universitet; []
    Keywords : 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

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

    Author : Christer Grönlund; Leif Sörnmo; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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

  5. 3. Modeling and assessment of human balance and movement disorders using inertial sensors

    Author : Fredrik Olsson; Kjartan Halvorsen; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Abstract : Inertial sensors and magnetometers are abundant in today's society, where they can be found in many of our everyday electronic devices, such as smart phones or smart watches. Their primary function is to measure the movement and orientation of the device and provide this information for the apps that request it. READ MORE

  6. 4. Neurotransmitter Imaging of the Human Brain : Detecting γ-Aminobutyric Acid (GABA) Using Magnetic Resonance Spectroscopy

    Author : Sofie Tapper; Peter Lundberg; Anders Tisell; Peter Zsigmond; Richard Edden; Linköpings universitet; []
    Keywords : ;

    Abstract : Introduction: In this thesis, MEGA-edited Magnetic Resonance Spectroscopy (MRS) has been used for the purpose of non-invasive detection of !- aminobutyric acid (GABA) within the brain. GABA is the main inhibitory neurotransmitter in the human central nervous system, and glutamate is the corresponding main excitatory neurotransmitter. READ MORE

  7. 5. Validation of a novel PET imaging marker for dopaminergic degeneration in Parkinson’s disease patients

    Author : Vera S Kerstens; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background: There is a need for an objective disease progression marker for Parkinson’s disease (PD). DAT measurement with PET-radioligand [18F]FE-PE2I has so far shown to be promising with its favorable kinetics, low production of metabolites, and ability to image the whole nigrostriatal pathway.
