   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; anterior cruciate ligament; KT-1000 arthrometer; knee evaluation systems; knee; laxity; right left knee laxity difference;

   Sammanfattning : The aim of the study was to analyse the outcome and function after anterior cruciate ligament(ACL) reconstruction using different evaluation systems. Special emphasis was placed on thesagittal knee laxity as measured with the KT-1000 arthrometer. LÄS MER

3. 2. Estimating Human Limb Motion Using Skin Texture and Particle Filtering

   Författare :Björn Holmberg; Håkan Lanshammar; Virgil Stokes; Christopher L. Vaughan; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Human motion analysis; Skin texture; Monte Carlo estimation; Particle filter; Mutual Information; Simulated Annealing; Marker-free; Rigid body transformation; 2D correlation; Systems engineering; Systemteknik;

   Sammanfattning : Estimating human motion is the topic of this thesis. We are interested in accurately estimating the motion of a human body using only video images capturing the subject in motion. Video images from up to two cameras are considered.The first main topic of the thesis is to investigate a new type of input data. LÄS MER

4. 3. On methods of evaluation of lower extremity eccentric muscle performance and loading

   Författare :Pär Westblad; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Biomechanics; eccentric; electromyography; isokinetic; methods; muscle endurance; pilot projects; reproducibility of results; strain; thigh; tibia.;

   Sammanfattning : This investigation has developed and evaluated methods for measuring eccentric muscle function and loading of the human lower extremity, including isokinetic tests of knee extensor muscle performance and a comprehensive in vivo method for conditions of functional loading. For measurement of knee extensor muscle performance, a protocol of 100 repetitive maximal actions at 90° was applied using a Biodex isokinetic dynamometer. LÄS MER

5. 4. Analysis of body motions based on optical markers. Accuracy, error analysis and clinical applications

   Författare :Roy Tranberg; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Instrumented gait analysis Motion analysis Skin markers Optical tracking system;

   Sammanfattning : This thesis aims to evaluate the influence of soft-tissue artefacts on analyses of body motions based on optical markers. A second aim is to apply instrumented gait analysis in clinical situations. Introduction: Instrumented gait analysis has been used since 1960 as a clinical evaluation/investigative tool at orthopaedic clinics. LÄS MER

7. 5. Prostate cancer and bone cell interactions : implications for metastatic growth and therapy

   Författare :Annika Nordstrand; Pernilla Wikström; Anders Widmark; Jonas Nilsson; Päivi Östling; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; onkologi; Oncology;

   Sammanfattning : The skeleton is the most common site of prostate cancer bone metastasis, and at present, there are no curable treatments for these patients. To further understand what stimulates tumor cell growth in the bone microenvironment and to find suitable therapies, reliable model systems are needed. LÄS MER
