1. The Fight on the Flights : Emergency evacuations – human physiological performance, leg muscle activity and gait biomechanics during exhaustive stair and slope ascent
Abstract : Physical exhaustion can constrain stair ascending capacity during emergency evacuation. The overall aim of this research was to explore and compare stair ascending capacities and physiological limitations when using two different modes: 1) self-preferred pace on three different public stairways, and 2) four machine-controlled paces on a stair machine corresponding to different percentages of maximal aerobic capacity (V̇O2max).

2. Biomechanical analyses of flywheel resistance exercise : From a space- and ground-based perspective
Abstract : Astronauts suffer degradation of postural muscles and weight-bearing bones during long-duration spaceflight. Resistance exercise is used as a primary countermeasure against these degradations. READ MORE

3. Quantification of skeletal, muscular and kinematics parameters in scoliosis : methodological and clinical studies
Abstract : This dissertation presents new methods derived for precise evaluation of a number of anatomical and functional variables of the complex thoracospinal deformity in scoliosis. By consensus the scoliotic angle at the frontal plane is measured on radiographs using the Cobb method. READ MORE

4. On methods of evaluation of lower extremity eccentric muscle performance and loading
Abstract : 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. READ MORE

5. Constrained Optimization for Prediction of Posture
Abstract : 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. READ MORE
