  1. 1. Vibration-induced muscle injury in the hand - experimental and clinical studies

    Författare :Lars Necking; Malmö Handkirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatologi; Surgery; muscle morphometry; intrinsic hand muscle; muscle strength; muscle injury; hand weakness; Vibration exposure; hand-arm vibration syndrome; orthopaedics; traumatology; Kirurgi; ortopedi;

    Sammanfattning : Exposure to vibration is known to cause vasospastic white fingers and/or sensorineural symtoms such as numbness and tingling in fingers and/or musculoskeletal disorders such as reduction in muscle force, fatigue and reduced endurance. Classifications for the vasospastic and sensorineural symptoms are established. LÄS MER

  3. 2. Brain processing of experimental muscle pain and its interrelation with proprioception and muscle fatigue : positron emission tomography study

    Författare :Alexander Korotkov; Docent Tomas Graven-Nielsen; Umeå universitet; []
    Nyckelord :Experimental muscle pain; Hypertonic saline; Kinesthesia; Proprioception; Movement; Vibration; Muscle fatigue; Brain; Imaging; Positron emission tomography; Regional cerebral blood flow;

    Sammanfattning : Chronic muscle pain is a significant medical and social problem and better understanding of the pathophysiological mechanisms involved is an important requirement for further development of diagnostics, treatment and rehabilitation methods. Experimental imaging studies have investigated functional neuroanatomy of different pain components. LÄS MER

  4. 3. Non-invasive measurement of skeletal muscle blood flow using by photoplethysmography. Experimental studies on the human leg

    Författare :Qiuxia Zhang; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; photoplethysmography; skeletal muscle blood flow; perfusion pressure; intramuscular pressure; venous obstruction; muscle exercise; non-invasive; limb elevation; vibration exposure; hyperaemia; foot pump.;

    Sammanfattning : The purpose of this thesis was to validate a new non-invasive photoplethysmography (PPG) method for measuring relative changes in local muscle blood flow (MBF) in the human leg. Experimental conditions expected to impede or increase local MBF were used to test responsiveness of the PPG. LÄS MER

  5. 4. Bone and fat tissue in children and adolescents: studies with focus on osteocalcin

    Författare :Bojan Tubić; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; osteocalcin; obesity; adiponectin; carboxylation; anorexia nervosa; paediatric; bone turnover markers; bone mass; whole body vibration; muscle;

    Sammanfattning : The general AIM was to investigate the possible interplay between bone and fat tissue through clinical studies of children and adolescents. Osteocalcin (OC), a bone formation marker, has been proposed to act as a link between bone and energy metabolism in mice, but human data are inconclusive. LÄS MER

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

    Författare :Charlotte Åström; Gunnevi Sundelin; Lage Burström; Stefan Karlsson; Karin Harms-Ringdahl; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Electromyography; drivers; hand-arm vibration; trapezius; whole-body vibration; Physiotherapy; Sjukgymnastik fysioterapi;

    Sammanfattning : 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). LÄS MER
