  2. 1. Muscle Thixotropy : Implications for Human Motor Control

    Author : Hans Axelson; Karl-Erik Hagbarth; Mikael Elam; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Motor control; Skeletal muscle; Thixotropy; History-dependent; EMG; Voluntary contractions; Neurovetenskap; Neurology; 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

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

    Author : Benoni B. Edin; Umeå universitet; []
    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

  5. 3. Muscular forces from static optimization

    Author : Sofia Heintz; Anders Eriksson; Elena Gutierrez-Farewik; Anton Arndt; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; movement analysis; muscle forces; static optimization; Other engineering mechanics; 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

  6. 4. The Fight on the Flights : Emergency evacuations – human physiological performance, leg muscle activity and gait biomechanics during exhaustive stair and slope ascent

    Author : Amitava Halder; Ergonomi och aerosolteknologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Stair climbing evacuation; Physical work capacity; Physiological constraints; Endurance; Energy expenditure; Oxygen consumption; Electromyography; Muscle fatigue; Incline gait biomechanics; Ground reaction forces; Required coefficient of friction;

    Abstract : Physical exhaustion can constrain stair ascending capacity during emergency evacuation. The overall aim of this research was to explore and compare stair ascending capacities and physiological limitations when using two different modes: 1) self-preferred pace on three different public stairways, and 2) four machine-controlled paces on a stair machine corresponding to different percentages of maximal aerobic capacity (V̇O2max).

  7. 5. Mastication in jaw muscle pain

    Author : Samaa Al Sayegh; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background: Integrated Pain Adaptation Models suggest a possible pain-motor interaction. Mechanisms affecting the jaw muscle spindles seem to affect the ability to bite and chew, suggesting that jaw muscle pain may be a potential modifier of mastication in humans. READ MORE
