  2. 21. Acute and early chronic responses to resistance exercise using flywheel or weights

    Author : Lena Norrbrand; Per Tesch; Ola Eiken; Per Aagaard; Mittuniversitetet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; electromyography; flywheel; magnetic resonance imaging; resistance exercise; Sports; Idrott;

    Abstract : Resistance exercise using weights typically offers constant external load during coupled shortening (concentric) and lengthening (eccentric) muscle actions in sets of consecutive repetitions until failure. However, the constant external load and the inherent capability of skeletal muscle to produce greater force in the eccentric compared with the concentric action, would infer that most actions are executed with incomplete motor unit involvement.

  4. 22. Anterior cruciate ligament reconstruction surgery, aspects of graft choice, graft fixation and bone mineral loss

    Author : Sven Stener; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anterior cruciate ligament; Reconstruction; Revision; PLLA; Bone mineral areal mass; DEXA;

    Abstract : The aim of this thesis was to measure bone mineral changes in the calcanei, hips and lumbar spine of patients reconstructed with bone-patellar tendon-bone (BPTB) or hamstring tendon (HT) autografts following anterior cruciate ligament (ACL) injury. Furthermore, the aim was to compare the clinical results after ACL revision reconstruction with either reharvested ipsilateral or contralateral BPTB autografts. READ MORE

  5. 23. Ultrasound-guided regional anesthesia in children and adults: aspects on central and peripheral blocks

    Author : Märit Lundblad; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The universal use of regional anesthesia has previously been hampered by fundamental factors, e.g. excessive failure rates, inability to detected anatomical variations and fear for unintentional tissue damage; all due to the inherent imprecision of previous localization techniques.

  6. 24. Musculoskeletal ultrasound : for diagnostics and treatment guidance in the orthopaedic outpatient care

    Author : Kerstin Sunding; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Accuracy;

    Abstract : Ultrasound (US) has shown to be of great value in diagnostics and treatment of injuries and chronic pain disorders of the musculoskeletal system. Today, it is considered to be a suitable method when investigating superficially located tendons. Another exciting field of application is the use of US for guidance of different invasive treatments.

  7. 25. 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
