  1. 1. In Vivo Evaluation of Skeletal Muscle Morphological and Mechanical Properties using Medical Imaging

    Författare :Zhongzheng Wang; Ruoli Wang; Elena Gutierrez Farewik; Rodrigo Moreno; Jonas Stålhand; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Muscle volume; fascicle length; pennation angle; anisotropy; three-dimensional freehand ultrasound; magnetic resonance imaging; diffusion tensor imaging; magnetic resonance elastography; Muskelvolym; fascikellängd; pennationsvinkel; anisotropi; tredimensionellt frihandsultraljud; magnetisk resonanstomografi; diffusionstensoravbildning; magnetisk resonanselastografi; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : Skeletal muscles are soft tissues that play an important role in maintaining body posture and enabling movements through force generation. The force-generating capacity is associated with the morphological and mechanical properties of the muscle. LÄS MER

  3. 2. Biomechanical consequences of gait impairment at the ankle and foot : Injury, malalignment, and co-contraction

    Författare :Ruoli Wang; Elena Gutierrez-Farewik; Eva Broström; Eriksson Anders; Ilse Jonkers; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; muscle function; gait analysis; induced acceleration; foot kinematics; dynamic joint stiffness;

    Sammanfattning : The human foot contributes significantly to the function of the whole lower extremity during standing and locomotion. Nevertheless, the foot and ankle often suffer injuries and are affected by many musculoskeletal and neurological pathologies. LÄS MER

  4. 3. Biomechanical Consequences of Foot and Ankle Injury and Deformity: Kinematics and Muscle Function

    Författare :Ruoli Wang; Elena Gutierrez-Farewik; Eva Broström; Eriksson Anders; Toni Arndt; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering mechanics; Teknisk mekanik;

    Sammanfattning : The overall aim of this thesis was to discuss kinematics and muscle function changes due to foot and ankle injury or deformity. The first study aims to characterize gait patterns of subjects with a common lower limb injury, ankle fractures. LÄS MER

  5. 4. High-Density Electromyography-Based Methods for Joint Torque Prediction and Motor Unit Behavior Observation

    Författare :Asta Kizyte; Ruoli Wang; Elena Gutierrez-Farewik; Christian Antfolk; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ankle; isometric contractions; machine learning; neuromuscular control; spinal cord injury; Fotled; isometriska kontraktioner; maskininlärning; neuromuskulär kontroll; ryggmärgsskada; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : Electromyography (EMG) is a technique that measures the electrical activity of muscles. It reflects muscle activation and provides an interface to the central nervous system at the level of the muscle or individual motor units, which helps us understand the mechanisms of muscle force production, control, and coordination.

  7. 5. Facilitating Exoskeletons in Daily Use : Simulations and Predictions for Design and Control

    Författare :Yi-Xing Liu; Elena Gutierrez-Farewik; Ruoli Wang; Christian Smith; Shaoping Bai; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Robotic Exoskeletons; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : Lower limb exoskeletons have been extensively developed over the last several decades for people with and without movement disorders. Although lower limb exoskeletons have been shown to provide effective assistance to improve gait and reduce metabolic cost during movements, they are often heavy, bulky and uncomfortable. LÄS MER
