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

    Author : Christer Grönlund; Leif Sörnmo; Umeå universitet; []
    Keywords : 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;

    Abstract : 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). READ MORE

  4. 2. Biomechanical studies of finger extension function. Analysis with a new force measuring device and ultrasound examination in rheumatoid arthritis and healhty muscles

    Author : Sofia Brorsson; Elena Gutierrez Farewik; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Grip force; finger extension force; ultrasound; hand exercise; rheumatoid arthritis; muscle architecture; GAT; DASH; SF-36; Muscles;

    Abstract : Aims: The overall aim of this thesis was to further our understanding of extensor muscles and their role for hand function. The aims of the studies were: To develop and evaluate a new device for finger extensor force measurements. To evaluate ultrasound as a tool for assessment of muscle architecture. READ MORE

  5. 3. Walking efficiently with smart springs

    Author : Israel Luis; Elena Gutierrez-Farewik; Ruoli Wang; Benjamin J. Fregly; KTH; []
    Keywords : Musculoskeletal modeling and simulation; muscle-tendon biomechanics; muscle parameter calibration; metabolic energy models; gait analysis; exoskeleton assistance; biomechanics; Biomekanisk modellering och simulering; rörelseorganen; biomekanik; muskel; muskelmodell och muskelarkitektur; metabolisk energi och kostnad; gång; gånganalys; exoskelett; hjälpmedel; gångpatologi; Teknisk mekanik; Engineering Mechanics;

    Abstract : Numerous assistive exoskeletons have been developed in recent years to assist walking in individuals with and without motor disorders. A standard metric to measure the efficacy of assistance is the change in the metabolic energy cost between unassisted and assisted conditions. READ MORE

  6. 4. Cell therapy for denervated tissue

    Author : Roine El-Habta; Ludvig J. Backman; Paul J. Kingham; Patrik Danielson; António Salgado; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adipose tissue-derived stem cell; cell therapy; denervation; differentiation; myoblast; peripheral nerve injury; proliferation; regeneration; skeletal muscle; stromal vascular fraction; survival; tendon; cellforskning; cell research; Medical Cell Biology; medicinsk cellbiologi;

    Abstract : Background: Peripheral nerve injury results in denervation of tendons and muscles. The biology of denervated muscle has been well studied but little is known about the associated tendons. READ MORE

  7. 5. Evaluation of surgical methods for sleep apnea and snoring

    Author : Thorbjörn Holmlund; Diana Berggren; Eva Levring Jäghagen; Karl Franklin; Sören Berg; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Sleep apnea syndromes; adverse effects; mortality; radiofrequency; sham surgery; randomized controlled trial; daytime sleepiness; snoring; tonsillar hypertrophy; tonsillectomy; cytoskeleton; desmin; dystrophin; muscle fiber; palatopharyngeus; soft palate; uvula.; Oto-Rhino-Laryngology; oto-rhino-laryngologi;

    Abstract : Background: Snoring and obstructive sleep apnea (OSA) are both common disorders with a number of negative health effects. The safety and efficacy of treating snoring and OSA surgically have been questioned and there has been a lack of studies in the field. READ MORE
