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

5. 3. 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

6. 4. 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

7. 5. Muscular forces from static optimization

   Author : Sofia Heintz; Anders Eriksson; Elena Gutierrez-Farewik; Anton Arndt; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; movement analysis; muscle forces; static optimization; Other engineering mechanics; Övrig teknisk mekanik;

   Abstract : At every joint there is a redundant set of muscle activated during movement or loading of the system. Optimization techniques are needed to evaluate individual forces in every muscle. The objective in this thesis was to use static optimization techniques to calculate individual muscle forces in the human extremities. READ MORE
