1. 41. 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.

3. 42. Schizophrenia as a systemic disorder : studies of peripheral and central biological functions

   Författare :Lena Flyckt; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :schizophrenia; systemic disease; membrane function; tyrosine transport; muscle biopsy; muscle fibre atrophy; macro EMG; cognitive functions; neurological signs; finger-tapping;

   Sammanfattning : Psychiatric disturbances with an onset in adulthood may show subtle signs in childhood and school age. This is particularly applicable to patients with schizophrenia. LÄS MER

4. 43. Electromyogram Signal Enhancement and Upper-Limb Myoelectric Pattern Recognition

   Författare :Sara Abbaspour; Maria Lindén; Christian Antfolk; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; elektronik; Electronics;

   Sammanfattning : Losing a limb causes difficulties in our daily life. To regain the ability to live an independent life, artificial limbs have been developed. Hand prostheses belong to a group of artificial limbs that can be controlled by the user through the activity of the remnant muscles above the amputation. LÄS MER

5. 44. The electromyographic signal used for control of upper extremity prostheses and for quantification of motor blockade during epidural anaesthesia

   Författare :Lennart Philipson; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : A contribution of biomedical research engineering has been the development of detection and analysis methods for the electromyographic (EMG) signal and its application to health care problems. The present thesis describes the use of EMG signals for two such applications: Aid in the control of multifunctional upper limb prostheses and for quantification of motor blockade during epidural anaesthesia.

7. 45. Muscular forces from static optimization

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

   Sammanfattning : 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. LÄS MER
