1. Bias and Precision in Biomechanical Exposure Assessment : Making the Most of our Methods
Sammanfattning : Background: Insufficient exposure assessment is a suggested contributing factor to the current lack of clearly characterised relationships between occupational biomechanical risk factors and musculoskeletal disorders. Minimal attention has been paid to the potential bias of measurement tools from expected true values (i.e. LÄS MER
2. Methods for measuring physical workload with relevance for musculoskeletal disorders of neck and upper limb
Sammanfattning : Work-related musculoskeletal disorders of the neck and upper limb are a major problem. Women in repetitive manual work is one large affected group. Preventive actions are hampered by the lack of knowledge regarding quantitative exposure-response relations for physical workload. LÄS MER
3. Sensorimotor function following anterior cruciate ligament injury : movement control, proprioception and neuropsychological perspectives
Sammanfattning : Background: The high incidence of anterior cruciate ligament (ACL) injuries in sports suggests an involvement of both biomechanical and neurocognitive risk factors. Athletes are constantly exposed to challenging sports scenarios, which are often characterised by high-intensity movements combined with a multi-stimuli environment and continuous psychological pressure.

4. Zero crossing rate as an index of electromyographic spectral alterations and its applications to ergonomics
Sammanfattning : .... LÄS MER
5. A Signal Processing Approach to Practical Neurophysiology : A Search for Improved Methods in Clinical Routine and Research
Sammanfattning : Signal processing within the neurophysiological field is challenging and requires short processing time and reliable results. In this thesis, three main problems are considered.First, a modified line source model for simulation of muscle action potentials (APs) is presented. LÄS MER
