  1. 1. Human muscle spindles : complex morphology and structural organisation

    Författare :Jing-Xia Liu; William K. Ovalle; Umeå universitet; []
    Nyckelord :human; muscle spindle; intrafusal fiber; aging; biceps brachii; deep muscles of the neck; MyHC; mATPase; SERCA; anatomi; Human Anatomy;

    Sammanfattning : 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. LÄS MER

  3. 2. Spatio-temporal processing of surface electromyographic signals : information on neuromuscular function and control

    Författare :Christer Grönlund; Leif Sörnmo; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EMG; multichannel surface electromyography; motor unit action potentials; conduction velocity; muscle architecture; signal quality; spatial distributions; synchronization; muscle function; motor control; biomedicinsk strålningsvetenskap; Biomedical Radiation Science;

    Sammanfattning : During muscle contraction, electrical signals are generated by the muscle cells. The analysis of those signals is called electromyography (EMG). The EMG signal is mainly determined by physiological factors including so called central factors (central nervous system origin) and peripheral factors (muscle tissue origin). LÄS MER

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

    Författare :Eva Pontén; Bertil Romanus; Umeå universitet; []
    Nyckelord :laser diffraction; sarcomere length; tendon transfer; spasticity; muscle morphology; myosin heavy chain; capillary; rabbit; human; cerebral palsy; stroke; handkirurgi; hand surgery;

    Sammanfattning : 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. LÄS MER

  5. 4. The electromyographic signal used for control of upper extremity prostheses and for quantification of motor blockade during epidural anaesthesia

    Författare :Lennart Philipson; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : A contribution of biomedical research engineering has been the development of detection and analysis methods for the electromyographic (EMG) signal and its application to health care problems. The present thesis describes the use of EMG signals for two such applications: Aid in the control of multifunctional upper limb prostheses and for quantification of motor blockade during epidural anaesthesia.
