  1. 1. Prolonged Modulation of the Micturition Reflex by Electrical Stimulation

    Författare :Chong-He Jiang; Sivert Lindström; Magnus Fall; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intravesical electrical stimulation; IVES; bladder evacuation problems; bladder; micturition reflex; Urology and andrology; Urologi och andrologi;

    Sammanfattning : Intravesical electrical stimulation (IVES) has been used in treatment of patients with urinary bladder dysfunctions for more than four decades. While some investigators have reported excellent results others have observed less convincing effects or outright failures. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  5. 4. Model-based optimization for individualized deep brain stimulation

    Författare :Rubén Cubo; Alexander Medvedev; Madeleine Lowery; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Neuromodulation; Deep Brain Stimulation; Inverse Problems; Optimization; Finite Element Methods; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Sammanfattning : Deep Brain Stimulation (DBS) is an established therapy that is predominantly  utilized in treating the symptoms of neurodegenerative diseases such as Parkinson's Disease and Essential Tremor, crippling diseases like Chronic Pain and Epilepsy, and psychiatric diseases such as Schizophrenia and Depression. Due to its invasive nature, DBS is considered as a last resort therapy. LÄS MER

  7. 5. Neuromuscular aspects of eccentric knee extensor actions : effects of electrical stimulation, age, gender and training

    Författare :Jan Seger; Alf Thorstensson; Roger Enoka; Gymnastik- och idrottshögskolan; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; Fysiologi; children; concentric; eccentric; efficiency; electrical stimulation; electromyography; growth; inhibition; isokinetic; specificity; strength; training;

    Sammanfattning : The overall aim of this thesis was to study the effects of electrical stimulation, age, gender and training on the torque- and EMG-velocity relationships during eccentric knee extensor muscle actions in man. An isokinetic custom-built dynamometer was evaluated and used throughout the thesis. LÄS MER
