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

    Författare :Anna Trulsson; Människan i rörelse: hälsa och rehabilitering; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 17. Tactile Sensory Control of Dexterous Manipulation in Humans

    Författare :Ingvars Birznieks; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; cutaneous sensibility; tactile afferents; fingertip force; grasp stability; human hand; manipulation; object shape; precision grip; sensorimotor control; coding; Fysiologi; Physiology; Fysiologi; fysiologi; Physiology;

    Sammanfattning : During dexterous manipulation with the fingertips, forces are applied to objects' surfaces. To achieve grasp stability, these forces must be appropriate given the properties of the objects and the skin of the fingertips, and the nature of the task. LÄS MER

  4. 18. Analysis of Adaptation in Human Postural Control

    Författare :Per-Anders Fransson; Lund näs- och halssjukdomar Öron-; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physical medicine; kinesitherapy; revalidation; rehabilitation; Rehabilitering medicinsk och social ; Adaptation; Postural control; Proprioception; Vestibular; Posturography; neuropsykologi; Neurologi; neurophysiology; neuropsychology; Neurology; hörsel- och talorganen; audiologi; Otorinolaryngologi; auditive system and speech; audiology; Otorhinolaryngology; Movement pattern; Sensorimotor integration; Muscle fatigue; Age; Cutaneous sensation; neurofysiologi;

    Sammanfattning : The ability to obtain correct balance control information and adjust motor performance appropriately are essential elements in effective postural control. However, functional disorders may affect the reliability of receptor information and ability to carry out corrective motions needed to maintain balance. LÄS MER

  5. 19. Restorative and neuroprotective treatment strategies for Parkinson’s disease: tudies on fetal dopamine cell transplants and GDNF delivery by intracerebral injections and recombinant AAV vectors

    Författare :Deniz Kirik; Neurobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adeno-associated virus; regeneration; neuroprotection; glial-cell-line-derived-neurotrophic factor; cell death; substantia nigra; dopamine; neurofysiologi; neuropsykologi; Neurologi; neurophysiology; neuropsychology; Neurology; tyrosine hydroxylase; sensorimotor behavior; transplantation; gene therapy;

    Sammanfattning : The intrastriatal 6-hydroxydopamine lesion model in rats is particularly useful in studies testing new therapeutic strategies for Parkinson’s disease. This thesis work (1) describes the characterization of the motor deficits after different types of intrastriatal lesions and identifies the four-site terminal lesion as a model of symptomatic Parkinson’s disease; (2) using the same model, provides evidence that the functional impact of the dopamine cell grafts are dependent on interactions with the host brain; (3) demonstrates that protection or restitution of normal motor function after 6-hydroxydopamine lesions can be achieved if glial cell line-derived neurotrophic factor is administered in the striatum at the time of the terminal fiber degeneration.

  7. 20. Visual and proprioceptive control of arm movements : studies of development and dysfunction

    Författare :Birgit Rösblad; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Vision; proprioception; reaching; pointing; arm movements; child; motor impairments; sensorimotor development;

    Sammanfattning : The aim of this dissertation was to examine the role of sensory information for control of goal-directed arm movements in children. The role of visual and proprioceptive information on the target for end point accuracy was examined in normal 4- to 12-year- old children (Study I), and in children with motor impairments (Study II).
