1. 1. Methods to assess physical load at work : With a focus on the neck and upper extremities

   Författare :Peter Palm; Mikael Forsman; Magnus Svartengren; Svend Erik Mathiassen; Eva Vingård; Esa Pekka Takala; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; risk assessment; physical load; upper extremities; ergonomics; Occupational and Environmental Medicine; Arbets- och miljömedicin;

   Sammanfattning : To prevent work-related musculoskeletal disorders (MSDs), useful, reliable and valid methods for assessing physical workload and risks for MSDs are needed. Ergonomists often assess work by short visual observations without a specific tool. LÄS MER

3. 2. Subject-specific musculoskeletal modeling of the lower extremities in persons with unilateral cerebral palsy

   Författare :Olesya Klets; Elena Gutierrez-Farewik; Sven Kleiven; KTH; []
   Nyckelord :cerebral palsy; moment arm; muscle length; hemiplegic; MRI; subject-specific; musculoskeletal modeling; lower extremities; muscle volume; Mechanical engineering; Maskinteknik;

   Sammanfattning : The computational musculoskeletal models that are used to study muscle moment-generating capacities of persons with movement disorders and planning treatment options must be accurate, and take into account the inter-individual variability of musculoskeletal geometry. In Paper I the methods of creating the subject-specific musculoskeletal model of the lower extremities from magnetic resonance images (MRIs) were developed. LÄS MER

4. 3. Early arterial disease of the lower extremities in diabetes : diagnostic evaluation and risk markers

   Författare :David Sahli; Maria Svensson; Eric Wahlberg; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; diabetes mellitus; ankle blood pressure; toe blood pressure; screening; risk markers; mediasclerosis; macroangiopathy; fibrinolysis; inflammation; MEDICINE; MEDICIN; Diabetology; Diabetologi;

   Sammanfattning : The aim of the present thesis was to assess the occurrence of early lower extremity arterial disease (LEAD) in patients with diabetes and to assess novel potential risk markers for development or worsening of LEAD in the same patients. In parallel different measures of impaired peripheral circulation were evaluated. LÄS MER

5. 4. Observation Methods and Imaging Techniques. Assessments of physical exposure in repetitive work with focus on neck and upper extremities

   Författare :Birgit Juul-Kristensen; Människan i rörelse: hälsa och rehabilitering; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; imaging techniques; force; electromyography; video recording; electrogoniometer; inclinometer; movement; posture; physical exposure; industrial work; repetitive; upper extremity; neck; observation method; musculoskeletal; Yrkesmedicin; arbetsmiljömedicin; industrial medicine; Occupational health; epidemiology; ultrasound; magnetic resonance;

   Sammanfattning : Observation methods and imaging techniques - assessments of physical exposure in repetitive work with focus on neck and upper extremities The aim of this thesis was to develop, establish and validate observation methods for exposure assessments in epidemiological studies of repetitive work. A second aim was to increase the quality of input data for biomechanical shoulder models, by reliability and validity studies of Magnetic Reso-nance Imaging (MRI) and Ultrasound Scanning (US).

7. 5. Near infrared spectroscopy for assessing oxygenation and hemodynamics in the upper extremities of healthy subjects and patients with work-related muscle pain

   Författare :Guilherme H. Elcadi; Albert G. Crenshaw; Mikael Forsman; Martin Fahlström; Svend Erik Mathiassen; Karen Sogaard; Högskolan i Gävle; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Near infrared spectroscopy; muscle oxygenation; hemodynamics; electromyography; extensor carpi radialis; trapezius; fysiologi;

   Sammanfattning : The prevalence of work-related muscle pain (WRMP) is large in the general population in the industrialized world. Despite significant advances over recent years in some research areas, the mechanisms of why WRMP occurs and the pathophysiological mechanisms behind the disorders are still unclear. LÄS MER
