1. Dynamic Changes in the Peripheral and the Central Nervous Systems in Patients with Prior Polio
Sammanfattning : After the acute spell of poliomyelitis, patients commonly suffers from sequelae of weakness. Some of these patients experience new weakness after a time period of stable symptoms.The aim of this thesis was to evaluate the possible mechanisms for persistent weakness and development of new weakness in prior polio patients.

2. 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
3. On the Utility of Representation Learning Algorithms for Myoelectric Interfacing
Sammanfattning : Electrical activity produced by muscles during voluntary movement is a reflection of the firing patterns of relevant motor neurons and, by extension, the latent motor intent driving the movement. Once transduced via electromyography (EMG) and converted into digital form, this activity can be processed to provide an estimate of the original motor intent and is as such a feasible basis for non-invasive efferent neural interfacing.

4. Spatio-temporal processing of surface electromyographic signals : information on neuromuscular function and control
Sammanfattning : During muscle contraction, electrical signals are generated by the muscle cells. The analysis of those signals is called electromyography (EMG). The EMG signal is mainly determined by physiological factors including so called central factors (central nervous system origin) and peripheral factors (muscle tissue origin). LÄS MER
5. 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
