  2. 1. Cognition Rehearsed : Recognition and Reproduction of Demonstrated Behavior

    Author : Erik Billing; Thomas Hellström; Lars Erik Janlert; Danica Kragic; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Behavior Recognition; Learning and Adaptive Systems; Learning from Demonstration; Neurocomputational Modeling; Robot Learning; computer and systems sciences; data- och systemvetenskap;

    Abstract : The work presented in this dissertation investigates techniques for robot Learning from Demonstration (LFD). LFD is a well established approach where the robot is to learn from a set of demonstrations. The dissertation focuses on LFD where a human teacher demonstrates a behavior by controlling the robot via teleoperation. READ MORE

  4. 2. Wearable systems and sensors for the assessment of motor control : Development and validation of methods for clinical assessment of idiopathic normal pressure hydrocephalus

    Author : Tomas Bäcklund; Nina Sundström; Anders Eklund; Jan Malm; Kaj Lindecrantz; Umeå universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gait; step-width; heel-heigt; balance; trunk sway; idiopathic normal pressure hydrocephalus; IMU; Inter-rater reliability; kinematics; medical informatics; medicinsk informatik;

    Abstract : Human gait and balance are controlled by automatic processes in the central nervous system, and in sensory and proprioceptive systems. If a disturbance occurs in any of these complex structures, it may lead to balance and gait problems. READ MORE

  5. 3. Losing control and developing concerns : The complexities of ageing postural control and fall-related concerns

    Author : Mascha Pauelsen; Lars Nyberg; Ulrik Röijezon; Irene Vikman; Jorunn Lægdheim Helbostad; Luleå tekniska universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ageing; postural balance; postural control; sensory and motor systems; fall-related concerns; fear of falling; neurological models; Physiotherapy; Fysioterapi;

    Abstract : With the world population shifting its proportions towards higher ages, it is imperative to increase healthspan rather than lifespan, both for the sakes of community sustainability as well as individual quality of life. One of the main means to obtain healthy ageing, is a concept called active ageing, as activity has shown to slow down the natural ageing process. READ MORE

  6. 4. Ontogenetic and comparative aspects of cerebellar and motor development

    Author : Maria Christensson; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurologi; neurophysiology; Neurology; neuropsychology; Medicine human and vertebrates ; time-translation; cross-species; cerebellum; motor adaptation; development; ferret; external granular layer; neuropsykologi; neurofysiologi; Medicin människa och djur ;

    Abstract : During the course of development the motor repertoire of animals and humans alike go through dramatic changes. New motor patterns arise; movements become coordinated, improve in precision and are at the same time continuously calibrated to the changing body dimensions. The cerebellum is critical for movement coordination and adaptation in adults. READ MORE

  7. 5. Subsystems of the basal ganglia and motor infrastructure

    Author : Iman Kamali Sarvestani; Örjan Ekeberg; Jeanette Hällgren-Kotaleski; Christelle Baunez; KTH; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Basal Ganglia; Action Selection; Motor Learning; Tectum; Superior Colliculus; Mesencephalic Locomotor Region; Reticulospinal Neurons; Computational Models;

    Abstract : The motor nervous system is one of the main systems of the body and is our principle means ofbehavior. Some of the most debilitating and wide spread disorders are motor systempathologies. In particular the basal ganglia are complex networks of the brain that control someaspects of movement in all vertebrates. READ MORE
