  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. Human muscle spindles complex morphology and structural organisation

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jing-Xia Liu; Högskolan i Gävle.; Umeå universitet.; [2004]
    Keywords : human; muscle spindIe; intrafusal fiber; aging; biceps brachii; deep muscles of the neck; MyHC; mATPase; SERCA; Human Anatomy; anatomi; muscle spindle;

    Abstract : Muscle spindles are skeletal muscle mechanoreceptors that mediate the stretch reflex and provide axial and limb position information to the central nervous system. They have been proposed to play a major role in the pathophysiology of muscle pain. READ MORE

  3. 3. Tendon transfer mechanics and donor muscle properties implications in surgical correction of upper limb muscle imbalance

    University dissertation from Integrativ medicinsk biologi

    Author : Eva Pontén; Umeå universitet.; [2003]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; laser diffraction; sarcomere length; tendon transfer; spasticity; muscle morphology; myosin heavy chain; capillary; rabbit; human; cerebral palsy; stroke; handkirurgi; handkirurgi;

    Abstract : Tendon transfer surgery is used to improve the hand function of patients with nerve injuries, spinal cord lesions, cerebral palsy (CP), stroke, or muscle injuries. The tendon of a muscle, usually with function opposite that of the lost muscle function, is transferred to the tendon of the deficient muscle. READ MORE

  4. 4. Mechanochemical Modeling of Smooth Muscle Activation

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Sae-Il Murtada; KTH.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biomechanics; Muscle contraction; Smooth muscle; Contractile unit; Filament overlap; Intracellular calcium; Carotid artery; Mathematical model;

    Abstract : Smooth muscle has an important role in several physiological processes, where it regulates the wall tension and the size of hollow organs. In blood vessels, the contraction and relaxation of smooth muscle contribute to the mechanical stability of the vessel wall and determines the diameter. READ MORE

  5. 5. MUSCLE TONE IMBALANCE IN HUMAN UPPER EXTREMITY An experimental study of muscle adaptation to altered tension

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Fredrik Einarsson; Göteborgs universitet.; Gothenburg University.; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; muscle biopsy; freeze storage; upper extremity; shoulder; human muscle; sarcomere; stress-strain relationship; stress relaxation; stiffness; elasticity; mechanical testing; morphology; spasticity; obstetric brachial plexus palsy; rotator cuff tear; tendon transfer;

    Abstract : Aim: The aim of this thesis was to improve outcome after tendon transfer and rotator cuff surgery by investigating the impact on response to passive mechanical testing and change in structural characteristics associated with longstanding changes in the tension of skeletal muscle in the human upper extremities in vivo. Patients and methods: The investigational method was in vitro assessment of human upper extremity muscles. READ MORE
