2. 1. Modelling of muscular force induced by non-isometric contraction

   Author : Natalia Kosterina; Anders Eriksson; Michael Günther; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Skeletal muscle; Muscular force; Concentric contractions; Eccentric con- tractions; History effect; Force modification; Muscle model; Musculoskeletal model;

   Abstract : The main objective of the study was to investigate and simulate skeletal muscleforce production during and after isometric contractions, active muscle lengtheningand active muscle shortening. The motivation behind this work was to improve thedominant model of muscle force generation based on the theories of Hill from 1938. READ MORE

4. 2. Electromyography and bite force studies of muscular function and dysfunction in masticatory muscles

   Author : Catharina Hagberg; []
   Keywords : Electromyography; bite force; contraction; isometric; masticatory muscles; mastication; intramuscular injections;

   Abstract : Electromyographic (EMG) activity versus bite force was studied during a gradually increased isometric contraction up to maximal effort for patients with painful masseter muscles and referents. The masseter muscle, the anterior temporal muscle and the descending part of the trapezius muscle were chosen for the recordings. READ MORE

5. 3. Muscular force production during non-isometric contractions: Towards numerical muscle modeling

   Author : Natalia Kosterina; Anders Eriksson; Ulla Svantesson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mouse skeletal muscle. Transient-length contractions. Muscular force. Force modification. History effect. Muscle modelling.; Engineering mechanics; Teknisk mekanik;

   Abstract : The main objective of the study was to investigate skeletal muscle force production during isometric contractions, active muscle stretches and shortenings. The motivation behind this work is to improve the dominant model of muscle contraction force generation based on the theories of Hill. READ MORE

6. 4. Force, falls and fear of falls in myotonic dystrophy type 1. Cross-sectional and longitudinal studies

   Author : Elisabet Hammarén; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; myotonic dystrophy; physiotherapy; muscle force; postural balance; gait; reliability; cross-sectional; prospective;

   Abstract : ABSTRACT Background: Myotonic dystrophy type 1 (DM1) is a neuromuscular multisystemic disorder with slowly progressive muscle weakness. The overall purpose of this thesis was, in adult patients with DM1, to investigate factors of importance for functional balance skills and falls, and to investigate the natural course of muscle force and functional balance impairments, with reliable measurement methods.

7. 5. 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 : 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;

   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.
