  1. 1. Motion Analysis and Postural Stability of Transtibial Prosthesis Users

    Författare :David Rusaw; Göteborgs universitet; []
    Nyckelord :Artificial limb; balance; electromyography EMG ; motion analysis; postural stability;

    Sammanfattning : The AIMS of the thesis were to critically evaluate motion analysis methods used during investigations of transtibial prosthesis users, and to propose improvements to these methods. Additionally, the aim was to evaluate if vibratory feedback could be used to improve postural stability in transtibial prosthesis users and how being a prosthesis user influenced muscular response to postural perturbations.

  3. 2. Rehabilitation and Evaluation after Anterior Cruciate Ligament Injury : Function, Stability and Postural Control

    Författare :Marketta Henriksson (Lysholm); Gunnar Németh; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Traditionally, the success of treatment after anterior cruciate ligament (ACL) injury has been judged from the recovery of muscle strength and knee range of motion (ROM), but also from the static knee stability after ACL reconstruction. However, since the sensory role of the ACL and surrounding tissues for the functional stability of the knee has been documented, the measurement of proprioceptive function related to knee stability is likely to become important in this evaluation.

  4. 3. Postural control and adaptation to threats to balance stability

    Författare :Mitesh Patel; Lund näs- och halssjukdomar Öron-; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Postural control; Visual; Vestibular; Somatosensory; Proprioception; Posturography; Complaint surface; Ageing; Mechanoreceptive sensation; Sleep deprivation; Adaptation; Muscle activity;

    Sammanfattning : Postural control is the ability to maintain equilibrium and orientation in a gravitational environment. It is dependent on feedback and feedforward mechanisms that generate appropriate corrective movement based on body-sway motion detected primarily by visual, vestibular, and proprioceptive sensory systems.

  5. 4. 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

  7. 5. Postural balance, physical activity and capacity among young people with intellectual disability

    Författare :Sven Blomqvist; Börje Rehn; Anita Wester; Gunnevi Sundelin; Rolf Moe-Nilssen; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mental retardation; postural stability; muscle strength; balance perturbation; aerobic capacity; young adults;

    Sammanfattning : The overall aim of this thesis was to investigate postural balance, physical activity, physical capacity and their associations in young people (16-20 years) with intellectual disability (ID), mild to moderate. The aim was also to study the reliability and concurrent validity of postural balance tests. LÄS MER
