1. Biomechanical studies of finger extension function. Analysis with a new force measuring device and ultrasound examination in rheumatoid arthritis and healhty muscles
Sammanfattning : Aims: The overall aim of this thesis was to further our understanding of extensor muscles and their role for hand function. The aims of the studies were: To develop and evaluate a new device for finger extensor force measurements. To evaluate ultrasound as a tool for assessment of muscle architecture. LÄS MER
2. Constrained Optimization for Prediction of Posture
Sammanfattning : The ability to stand still in one place is important in a variety of activities of daily living. For persons with motion disorders, orthopaedic treatment, which changes geometric or biomechanical properties, can improve the individual'sposture and walking ability. LÄS MER
3. Muscular forces from static optimization
Sammanfattning : At every joint there is a redundant set of muscle activated during movement or loading of the system. Optimization techniques are needed to evaluate individual forces in every muscle. The objective in this thesis was to use static optimization techniques to calculate individual muscle forces in the human extremities. LÄS MER
4. High-Density Electromyography-Based Methods for Joint Torque Prediction and Motor Unit Behavior Observation
Sammanfattning : Electromyography (EMG) is a technique that measures the electrical activity of muscles. It reflects muscle activation and provides an interface to the central nervous system at the level of the muscle or individual motor units, which helps us understand the mechanisms of muscle force production, control, and coordination.

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