  1. 1. Electromyography and bite force studies of muscular function and dysfunction in masticatory muscles

    University dissertation from Umeå : Umeå universitet

    Author : Catharina Hagberg; [1986]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Electromyography; bite force; contraction; isometric; masticatory muscles; mastication; intramuscular injections;

    Abstract : Electromyographic (EMG) activity versus bite force was studied during a gradually increased isometric contraction up to maximal effort for patients with painful masseter muscles and referents. The masseter muscle, the anterior temporal muscle and the descending part of the trapezius muscle were chosen for the recordings. READ MORE

  2. 2. On spinal mechanisms for reflex control in man modulation of Ia-afferent excitation with changes in muscle length, activation level and fatigue

    University dissertation from Stockholm : Karolinska institutet

    Author : Maria M. Nordlund; GIH. Gymnastik- och idrottshögskolan; Karolinska Institutet.; Karolinska Institutet.; [2004]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin Teknik; Medicine Technology; Electromyography; eccentric; concentric; presynaptic inhibition; H-reflex; central fatigue; twitch interpolation; muscle spindle; Electromyography; eccentric; concentric; presynaptic inhibition; H-reflex; central fatigue; twitch interpolation; muscle spindle;

    Abstract : To control muscle force, neural activation has to take alterations in muscle mechanics into account. This thesis assesses modulations in excitatory efficacy of Ia-afferents during muscle length changes at different levels of voluntary activation and during fatigue. READ MORE

  3. 3. Adaptive signal processing of surface electromyogram signals

    University dissertation from Umeå : Strålningsvetenskaper

    Author : Nils Östlund; Umeå universitet.; [2006]
    Keywords : Signalbehandling; electromyography; signal processing; Signalbehandling; biomedicinsk strålningsvetenskap; Biomedical Radiation Science;

    Abstract : Electromyography is the study of muscle function through the electrical signals from the muscles. In surface electromyography the electrical signal is detected on the skin. The signal arises from ion exchanges across the muscle fibres’ membranes. READ MORE

  4. 4. Effects of vibration on muscles in the neck and upper limbs with focus on occupational terrain vehicle drivers

    University dissertation from Umeå : Samhällsmedicin och rehabilitering

    Author : Charlotte Åström; Umeå universitet.; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Electromyography; drivers; hand-arm vibration; trapezius; whole-body vibration; INTERDISCIPLINARY RESEARCH AREAS Caring sciences Physiotherapy; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN Vårdvetenskap Sjukgymnastik fysioterapi;

    Abstract : Introduction: Occupational drivers of terrain vehicles are exposed to several risk factors associated with musculoskeletal symptoms in the lower back as well as in the neck and upper limbs. Vibration has been suggested to be a main risk factor. These drivers are exposed to both whole-body vibration (WBV) and hand-arm vibration (HAV). READ MORE

  5. 5. Methods for measuring physical workload with relevance for musculoskeletal disorders of neck and upper limb

    University dissertation from Department of Occupational and Environmental Medicine, Lund University

    Author : Gert-Åke Hansson; Lunds universitet.; Lund University.; [2000]
