  1. 1. 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

  3. 2. Legged locomotion : Balance, control and tools - from equation to action

    Författare :Christian Ridderström; KTH; []
    Nyckelord :legged locomotion; control; balance; legged machines; legged robots; walking robots; walking machines; compliance; platform stability;

    Sammanfattning : This thesis is about control and balance stability of leggedlocomotion. It also presents a combination of tools that makesit easier to design controllers for large and complicated robotsystems. The thesis is divided into four parts. LÄS MER

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

    Författare :Tomas Bäcklund; Nina Sundström; Anders Eklund; Jan Malm; Kaj Lindecrantz; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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;

    Sammanfattning : 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. LÄS MER

  5. 4. 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

  7. 5. 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
