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

    Författare :Mascha Pauelsen; Lars Nyberg; Ulrik Röijezon; Irene Vikman; Jorunn Lægdheim Helbostad; Luleå tekniska universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 2. Adaptation and learning in postural control

    Författare :Fredrik Tjernström; Lund näs- och halssjukdomar Öron-; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Postural control; Adaptation; Learning; Sensory reweighting;

    Sammanfattning : The importance of the ability to use bipedal stance and gait in everyday life cannot be underestimated. Bipedal stance is learned during childhood and constantly adapted to changing circumstances throughout life. Failure to attain and maintain the control of upright posture can have catastrophic consequences. LÄS MER

  4. 3. On the role of transversus abdominis in trunk motor control

    Författare :Martin Eriksson Crommert; Peter Engfeldt; Alf Thorstensson; Maria Ekblom; Birgitta Öberg; Örebro universitet; []
    Nyckelord :transversus abdominis; trunk muscles; EMG; intramuscular; IAP; motor control; postural control; spine stability; postural demand; MEDICINE; MEDICIN; Medicin; Medicine;

    Sammanfattning : All trunk muscles are important contributors to spine stability. However, the deepest abdominal muscle, transversus abdominis (TrA), with its characteristically horizontal fibre orientation seems to serve a unique function in trunk motor control. LÄS MER

  5. 4. 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

  7. 5. Human Postural Sway Modeling and Balance Impairment Detection

    Författare :Hedyeh Jafari; Thomas Gustafsson; George Nikolakopoulos; Fredrik Öhberg; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatic Control; Reglerteknik;

    Sammanfattning : Falls, Fear of falling (FoF), and low balance confidence pose significant threats to health and independence among older people. This thesis aims to study humans’ postural and balance mechanisms, from analyzing the effect of multisensory inputs on balance performance and balance-related concerns to modeling the postural sway through physical dynamics and data-driven approaches.
