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

    Author : Zhongzheng Wang; Ruoli Wang; Elena Gutierrez Farewik; Rodrigo Moreno; Jonas Stålhand; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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;

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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

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

    Abstract : 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. READ MORE
