  1. 1. Muscle Thixotropy Implications for Human Motor Control

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Hans Axelson; Uppsala universitet.; [2005]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Motor control; Skeletal muscle; Thixotropy; History-dependent; EMG; Voluntary contractions; Neurovetenskap; MEDICINE Dermatology and venerology; clinical genetics; internal medicine Internal medicine Neurology; MEDICIN Dermatologi och venerologi; klinisk genetik; invärtesmedicin Invärtesmedicin Neurologi;

    Abstract : Human skeletal muscles possess thixotropic, i.e. history-dependent mechanical properties. This means that the degree of passive muscle stiffness and resting tension is dependent on the immediately preceding history of contractions and length changes. READ MORE

  2. 2. Classification of muscle stretch receptor afferents in humans

    University dissertation from Umeå : Umeå universitet

    Author : Benoni B. Edin; Umeå universitet.; [1988]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Muscle spindles; Golgi tendon organs; Classification of muscle receptors; Microneurography; Human hand; Stretch sensitization; Voluntary contraction; Static position sensitivity; Fusimotor control;

    Abstract : The response patterns of human stretch receptors in the finger extensor muscles of the forearm were studied using the microneurography technique. Single-unit recordings were obtained from one-hundred and twenty-four afferents. READ MORE

  3. 3. Muscular forces from static optimization

    University dissertation from Stockholm : KTH

    Author : Sofia Heintz; KTH.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; movement analysis; muscle forces; static optimization; TECHNOLOGY Engineering mechanics Other engineering mechanics; TEKNIKVETENSKAP Teknisk mekanik Övrig teknisk mekanik;

    Abstract : At every joint there is a redundant set of muscle activated during movement or loading of the system. Optimization techniques are needed to evaluate individual forces in every muscle. The objective in this thesis was to use static optimization techniques to calculate individual muscle forces in the human extremities. READ MORE

  4. 4. A sensory role for the cruciate ligaments regulation of joint stability via reflexes onto the γ-muscle-spindle system

    University dissertation from Umeå : Umeå universitet

    Author : Per Sjölander; Umeå universitet.; [1989]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Joint afferent; Mechanoreceptor; Cruciate ligament; Fusimotor neuron; reflex; muscle spindle afferent; motor control; cat;

    Abstract : Reflex effects evoked by graded electrical stimulation of the posterior articular nerves (PAN) of the ipsi- and contralateral knee joints were investigated using both micro-electrode recordings from 7 - motoneurones and recordings from single muscle muscle spindle afferents. Spindle afferent responses were also recorded using natural stimulation of different types of receptors, to elucidate if the articular reflexes onto the y -motoneurones were potent enough to significantly alter the muscle spindle afferent activity.

  5. 5. Near infrared spectroscopy for assessing oxygenation and hemodynamics in the upper extremities of healthy subjects and patients with work-related muscle pain

    University dissertation from Umeå : Umeå University

    Author : Guilherme Hilgert Elcadi; Högskolan i Gävle.; Högskolan i Gävle.; Umeå universitet.; [2012]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Near infrared spectroscopy; muscle oxygenation; hemodynamics; electromyography; extensor carpi radialis; trapezius; fysiologi; Physiology;

    Abstract : The prevalence of work-related muscle pain (WRMP) is large in the general population in the industrialized world. Despite significant advances over recent years in some research areas, the mechanisms of why WRMP occurs and the pathophysiological mechanisms behind the disorders are still unclear. READ MORE
