  1. 1. Fluid dynamic principles for analysis of intracranial pressure control application towards space medicine and hydrocephalus

    University dissertation from Umeå : Umeå Universitet

    Author : Petter Holmlund; Umeå universitet.; Umeå universitet.; [2019]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intracranial pressure; posture; cerebrospinal fluid; microgravity; venous collapse; internal jugular vein; fluid dynamics; venous pressure; spaceflight-associated neuro-ocular syndrome; hydrocephalus; mathematical modeling; ultrasound; magnetic resonance imaging;

    Abstract : Intracranial pressure (ICP) is an important component of the fluid dynamic environment of the brain and plays a central role with regards to the maintenance of normal cerebral blood flow and neuronal function. However, many regulatory mechanisms controlling the ICP are still poorly understood. READ MORE

  2. 2. EMG and strength in trunk and hip muscles

    University dissertation from Stockholm : Karolinska Institutet

    Author : Eva A Andersson; GIH. Gymnastik- och idrottshögskolan; Karolinska Institutet.; Karolinska Institutet.; [1997]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICINE Physiology and pharmacology Physiology Neurophysiology; MEDICIN Fysiologi och farmakologi Fysiologi Neurofysiologi; abdominal muscles; biomechanics; electromyography; erector spinae; iliacus; iliopsoas; hip flexor muscles; locomotion; motor control; normalization; posture; psoas; quadratus lumborum; rehabilitation; running; sit-ups; strength; training exercises; u;

    Abstract : The overall aim of this thesis was to study the myouelectric activity of all major muscles involved in the movements and stabilization of the trunk, pelvis and hips during training exercises, postures, motor tasks, maximal strength performance and locomotion. By use of ultra-sound, EMG electrodes could be guided safely and accurately into muscles situated even close to the spinal column, such as psoas, quadratus lumborum and deep parts of erector spinae.

  3. 3. Cardiovascular regulation in women with vasovagal syncope With special reference to the venous system

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Johan Skoog; Linköpings universitet.; Linköpings universitet.; [2016]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Although vasovagal syncope (VVS) is a common clinical condition the mechanisms behind VVS remain elusive. Upright posture is the major trigger of VVS and lower limb blood pooling affecting cardiac output has been proposed as a major determinant. The overall aim of this thesis was twofold. READ MORE

  4. 4. Middle Ear Pressure; A New Method for Continuous Direct Measurements

    University dissertation from Department of Otorhinolaryngology, Lund University

    Author : Bo Tideholm; Lund University.; Lunds universitet.; [2000]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Otorhinolaryngology; man; physiology; sleep; posture; pressure; patulous Eustachian tube; middle ear; Ear; audiology; auditive system and speech; Otorinolaryngologi; audiologi; hörsel- och talorganen;

    Abstract : Disturbances in the pressure homeostasis of the middle ear (ME) system cause a pressure gradient across the tympanic membrane lessen the effectiveness of sound transmission and may be associated to development of chronic ME disease. An equipment for continuous direct pressure measurements was developed and was found to be accurate, base-line stabile and portable. READ MORE

  5. 5. Effects of gravity and posture on the human lung

    University dissertation from Stockholm : Karolinska Institutet, Department of Physiology and Pharmacology

    Author : Malin Rohdin; Karolinska Institutet.; Karolinska Institutet.; [2004]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acceleration; cardiac output; cardiogenic oscillations; closing volume; gas exchange; heart I-ate; human centrifuge; hypergravity; lung diffusing capacity; prone posture; pulmonary-capillary blood volume; rebreathing; single-breath washout; supine;

    Abstract : The presence of the gravitational force at the surface of Earth affects all of the organ systems in landliving creatures. The function of the lung is particularly susceptible to changes in the direction and magnitude of gravity because of the elastic structure of this organ. READ MORE
