  2. 1. Performance and Flotation-REST in Tests of Marksmanship, Problem-solving and Perceived Exertion

    Author : Henrik Bergman; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Flotation-REST; archery; performance; primary- and secondary process; creativity; originality; EMG;

    Abstract : This present thesis examines whether or not relaxation as floating may be exploited to reinforce primary process (inner-directed) orientation, and thereby enhance performance, creative problem-solving ability and originality. Two Articles are presented both using randomized factorial design. Article I include two subexperiments. READ MORE

  4. 2. Trapezius muscle fatigue and electromyographic frequency analysis

    Author : Tommy Öberg; Linköpings universitet; []
    Keywords : EMG; Spectrum; Frequency; Fatigue; Trapezius; Myalgia; MEDICINE; MEDICIN;

    Abstract : This study, comprising 6 separate articles, is concerned with different validity and reliability aspects of the electromyogram mean power frequency (MPF) as an estimator of localized musele fatigue in the trapezius muscle. A series of new, and partly controversial and problematic findings are reported. READ MORE

  5. 3. Ambulatory Monitoring and Analysis of Surface Electromyographic Signals in Ergonomic Field Studies - Methods and Applications

    Author : Leif Sandsjö; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trapezius; ergonomic assessment tools; long-term recording; wearable systems; EMG; musculoskeletal disorders; work-related;

    Abstract : Factors contributing to and the mechanisms behind the development of work-related musculoskeletal disorders (WMSDs) are still not fully known. Increased knowledge in this area is necessary in order to recommend appropriate actions to counteract the increasing costs to society and reduce the individual suffering related to these problems.

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

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

    Abstract : 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. READ MORE

  7. 5. Altered movement patterns and deviating muscular activity in individuals with anterior cruciate ligament injury

    Author : Anna Trulsson; Människan i rörelse: hälsa och rehabilitering; []
    Keywords : 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;

    Abstract : 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. READ MORE
