2. 1. Quadruped robot control and variable leg transmissions

   Author : Johan Ingvast; Jan Wikander; Harry Dankowicz; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; walking robot; quadruped; walking; crawl; trot; passively variable transmission; PVT; variable transmission; continuously variable transmission; velocity ratio; torque ratio; Other engineering mechanics; Övrig teknisk mekanik;

   Abstract : The research presented in this thesis regards walking of quadruped robots, and particularly the walking of the Warp1 robot. The motivation for the robot is to provide a platform for autonomous walking in rough terrain. The thesis contains six papers ranging from development tools to actuation of robot legs. READ MORE

4. 2. Gait speed, physical activity, cognitive function and dementia : associations in cross-sectional and longitudinal studies and validity of a physical activity questionnaire in very old people

   Author : Jerry Öhlin; Annika Toots; Birgitta Olofsson; Håkan Littbrand; Stefan Söderberg; Anna Cristina Åberg; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gait speed; cognitive function; dementia; physical activity; aged 80 and over; physiotherapy; fysioterapi;

   Abstract : Dementia and cognitive impairment are leading causes of disability in older people (≥ 65 years) and gait speed decline seem to be an early indicator of these conditions, sometimes preceding clinical symptoms. Dementia may be delayed or prevented with management of risk factors, such as low physical activity. READ MORE

5. 3. Gait speed and physical exercise in people with dementia

   Author : Annika Toots; Erik Rosendahl; Håkan Littbrand; Yngve Gustafson; Stephen Lord; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Exercise; dementia; residential facilities; postural balance; activities of daily living; cognitive function; mobility limitation; Alzheimer s disease; rehabilitation; frail elderly; gait speed; mortality; aged 80 and older;

   Abstract : The aim of the thesis was to investigate the importance of physical function for survival in very old people, and furthermore, whether physical exercise could influence physical function, cognitive function, and dependence in activities of daily living (ADLs) in older people with dementia living in nursing homes.The world’s population is ageing.

6. 4. Physical performance and physical activity in the later stage post-stroke

   Author : Christiane Carvalho; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cerebrovascular accident; exercise test; gait; healthy control; muscle strength; physical activity; physical therapy; rehabilitation; secondary prevention; stroke; walking;

   Abstract : Aims: The overall purpose of this thesis was to increase knowledge about physical performance and activity in the later stage post-stroke by measuring walking performance in different environments coupled to muscle strength, cardiorespiratory fitness evaluation and self-reported physical activity. Methods: The studies reported in the thesis included a total of 83 subjects with prior stroke living in the community and 144 clinically healthy subjects from the same area. READ MORE

7. 5. The influence of abdominal surgery on energy expenditure and working capacity

   Author : Margareta Öhrström; Människan i rörelse: hälsa och rehabilitering; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin människa och djur ; Medicine human and vertebrates ; maximum oxygen uptake; chemotherapy; walking; Energy expenditure; treatment outcome;

   Abstract : The overall aim of this work was to study the influence of surgery on energy expenditure (EE) during working capacity measurements and during walking. In the first study the aim was to investigate whether two different devices were sensitive enough to reveal differences in energy expenditure during treadmill walking, and if the measurements were reproducible.
