2. 1. Upper and Lower Motoneuron Lesions in Tetraplegia - Diagnostic and Therapeutic Implications of Electrical Stimulation

   Author : Ines Bersch; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Electrical stimulation; Tetraplegia; Upper motoneuron lesion; Lower motoneuron lesion; Motor point topography; Nerve transfer;

   Abstract : The overall objective of this thesis was to improve outcomes and predictability of the treatment of upper extremity function in patients with cervical spinal cord injury and tetraplegia by advancing the diagnostic and therapeutic tools employed in upper and lower motor neuron lesions. An overview is presented of the current knowledge about the principles of electrical stimulation and its usefulness and proven effects on the upper limb. READ MORE

4. 2. Gastric electrical stimulation. Studies in patients with intractable nausea and vomiting

   Author : Stina Andersson; Göteborgs universitet; []
   Keywords : gastric electrical stimulation; gastroparesis; gastroscopy; vomiting; gastric accommodation; drinking test; dyspepsia;

   Abstract : The most severe cases of gastroparesis are refractory to drugs. In the 1990s gastric electrical stimulation (GES) was introduced for treatment of nausea and vomiting in patients with diabetic and idiopathic gastroparesis. The electrodes and neurostimulator are usually placed with laparoscopy. READ MORE

5. 3. Conjugated Polymers for Neural Interfaces : Prospects, possibilities and future challenges

   Author : Maria Asplund; Hans von Holst; Olle Inganäs; Thomas Stieglitz; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; neuroprosthetics; conjugated polymers; conducting polymers; PEDOT; functional electrical stimulation; neural electrodes; Medical engineering; Medicinsk teknik; Neuroscience; Neurovetenskap; Functional materials; Funktionella material;

   Abstract : Within the field of neuroprosthetics the possibility to use implanted electrodes for communication with the nervous system is explored. Much effort is put into the material aspects of the electrode implant to increase charge injection capacity, suppress foreign body response and build micro sized electrode arrays allowing close contact with neurons.

6. 4. Towards Natural Control of Artificial Limbs

   Author : Max Jair Ortiz Catalan; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; epimysial electrodes; robotic prostheses; sensory feedback.; real-time and simultaneous prosthetic control; neurostimulation; pattern recognition; advanced prosthetic control; neural interfaces; artificial limbs; cuff electrodes; bone-anchored prostheses; osseointegration;

   Abstract : The use of implantable electrodes has been long thought as the solution for a more natural control of artificial limbs, as these offer access to long-term stable and physiologically appropriate sources of control, as well as the possibility to elicit appropriate sensory feedback via neurostimulation. Although these ideas have been explored since the 1960’s, the lack of a long-term stable human-machine interface has prevented the utilization of even the simplest implanted electrodes in clinically viable limb prostheses.

7. 5. Infrared Laser Stimulation of Cerebral Cortex Cells - Aspects of Heating and Cellular Responses

   Author : Rickard Liljemalm; Tobias Nyberg; Hans von Holst; Claus-Peter Richter; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; laser; modeling; heating; infrared neural stimulation; astrocytes; neurons; damage;

   Abstract : The research of functional stimulation of neural tissue is of great interest within the field of clinical neuroscience to further develop new neural prosthetics. A technique which has gained increased interest during the last couple of years is the stimulation of nervous tissue using infrared laser light. READ MORE
