1. Neural control of standing posture
Abstract : When humans are asked to stand normally, they are not completely motionless. Rather, small amounts of body movement, termed postural sway, can be observed. Although the postural sway of standing has been well described, the manner in which this sway is neurally controlled and its influence in tasks involving postural re-stabilization are not known.

2. The Impact of Stressful Postures on the Physical Workload in Nursing
Abstract : Nursing staff have an elevated risk of developing musculoskeletal disorders, in particular in the lower back area. Statistics produced by leading industrial nations show that back problems are the world’s number one work-related health problem, and that healthcare workers suffer from a greater occurrence of such problems than workers in other professions.

3. Seated postural reactions to mechanical shocks : laboratory studies with relevance for risk assessment and prevention of musculoskeletal disorders among drivers
Abstract : Professional drivers of off-road vehicles, driving on irregular terrain such as in forestry, agriculture and mining, are exposed to whole-body vibration and mechanical shocks. These driver groups have reported severe musculoskeletal problems in the spine, but the association to seated postural reactions is not fully understood. READ MORE

4. EMG and strength in trunk and hip muscles
Abstract : The overall aim of this thesis was to study the myouelectric activity of all major muscles involved in the movements and stabilization of the trunk, pelvis and hips during training exercises, postures, motor tasks, maximal strength performance and locomotion. By use of ultra-sound, EMG electrodes could be guided safely and accurately into muscles situated even close to the spinal column, such as psoas, quadratus lumborum and deep parts of erector spinae.

5. Active Muscle Responses in a Finite Element Human Body Model
Abstract : The development of automotive safety systems is moving towards an integration of systems thatare active before and during an impact. Consequently, there is a need to make a combinedanalysis of both the pre-crash and the in-crash phases, which leads to new requirements forHuman Body Models (HBMs) that today are used for crash simulations.
