2. 16. Evaluation of physical work capacity and leg muscle fatigue during exhaustive stair ascending evacuation

   Author : Amitava Halder; Ergonomi och aerosolteknologi; []
   Keywords : Stair climbing; Energy expenditure; Oxygen consumption; Electromyography; Muscle fatigue;

   Abstract : AbstractPhysical exhaustion can constrain human ascending work capacity and performance during emergency evacuation on stairs. The overall aim of this research was to explore and compare stair ascending capacities and physiological limitations during two different strategies: self-preferred pace in three different public stairways in the field, and controlled pace in a laboratory on a stair machine.

4. 17. Motion Analysis and Postural Stability of Transtibial Prosthesis Users

   Author : David Rusaw; Göteborgs universitet; []
   Keywords : Artificial limb; balance; electromyography EMG ; motion analysis; postural stability;

   Abstract : The AIMS of the thesis were to critically evaluate motion analysis methods used during investigations of transtibial prosthesis users, and to propose improvements to these methods. Additionally, the aim was to evaluate if vibratory feedback could be used to improve postural stability in transtibial prosthesis users and how being a prosthesis user influenced muscular response to postural perturbations.

5. 18. The Fight on the Flights : Emergency evacuations – human physiological performance, leg muscle activity and gait biomechanics during exhaustive stair and slope ascent

   Author : Amitava Halder; Ergonomi och aerosolteknologi; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Stair climbing evacuation; Physical work capacity; Physiological constraints; Endurance; Energy expenditure; Oxygen consumption; Electromyography; Muscle fatigue; Incline gait biomechanics; Ground reaction forces; Required coefficient of friction;

   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).

6. 19. Near infrared spectroscopy for assessing oxygenation and hemodynamics in the upper extremities of healthy subjects and patients with work-related muscle pain

   Author : Guilherme H. Elcadi; Albert G. Crenshaw; Mikael Forsman; Martin Fahlström; Svend Erik Mathiassen; Karen Sogaard; Högskolan i Gävle; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Near infrared spectroscopy; muscle oxygenation; hemodynamics; electromyography; extensor carpi radialis; trapezius; fysiologi;

   Abstract : The prevalence of work-related muscle pain (WRMP) is large in the general population in the industrialized world. Despite significant advances over recent years in some research areas, the mechanisms of why WRMP occurs and the pathophysiological mechanisms behind the disorders are still unclear. READ MORE

7. 20. Physical exposure, musculoskeletal symptoms and attitudes related to ICT use

   Author : Ewa Gustafsson; Göteborgs universitet; []
   Keywords : Input device; Wrist movements; Electrogoniometry; EMG; Muscle activity; Thumb movements; Working technique; Information and communication technology; Computer mouse; Mobile phone;

   Abstract : High prevalence of musculoskeletal symptoms/disorders in neck and upper extremities are reported among computer users. Considering the widespread use of information and communication technology (ICT) and mobile phones becoming more and more like computers with small keyboards it is of importance to identify the factors and conditions related to this use, that influence our health.
