2. 1. Losing control and developing concerns : The complexities of ageing postural control and fall-related concerns

   Author : Mascha Pauelsen; Lars Nyberg; Ulrik Röijezon; Irene Vikman; Jorunn Lægdheim Helbostad; Luleå tekniska universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ageing; postural balance; postural control; sensory and motor systems; fall-related concerns; fear of falling; neurological models; Physiotherapy; Fysioterapi;

   Abstract : With the world population shifting its proportions towards higher ages, it is imperative to increase healthspan rather than lifespan, both for the sakes of community sustainability as well as individual quality of life. One of the main means to obtain healthy ageing, is a concept called active ageing, as activity has shown to slow down the natural ageing process. READ MORE

4. 2. Neuronal mechanisms of feedback postural control

   Author : Li-Ju Hsu; Karolinska Institutet; Karolinska Institutet; []
   Keywords : postural control; equilibrium; body configuration; reticulospinal neurons; stretch receptor neurons; galvanic vestibular stimulation; artificial feedback; locomotion; spinalization; rabbit; lamprey;

   Abstract : Different species maintain a basic body posture due to the activity of the postural control system. An efficient control of the body orientation, as well as the body configuration, is important for standing and during locomotion. READ MORE

5. 3. Nervous mechanisms of postural control

   Author : Anastasia Karayannidou; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Postural control; equilibrium; body confguration; motor cortex; reticulospinal system; standing; locomotion; spinal cord injury; cat; rabbit; lamprey;

   Abstract : Maintenance of body confguration and orientation in space (postural control) is a vital motor function. A general goal of the present study was to analyze nervous feedback mechanisms for the maintenance of posture during different motor behaviors and with different postural perturbations. READ MORE

6. 4. Postural control and adaptation to threats to balance stability

   Author : Mitesh Patel; Lund näs- och halssjukdomar Öron-; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Postural control; Visual; Vestibular; Somatosensory; Proprioception; Posturography; Complaint surface; Ageing; Mechanoreceptive sensation; Sleep deprivation; Adaptation; Muscle activity;

   Abstract : Postural control is the ability to maintain equilibrium and orientation in a gravitational environment. It is dependent on feedback and feedforward mechanisms that generate appropriate corrective movement based on body-sway motion detected primarily by visual, vestibular, and proprioceptive sensory systems.

7. 5. Muscle Responses of Car Occupants: Numerical Modeling and Volunteer Experiments under Pre-Crash Braking Conditions

   Author : Jonas Östh; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; feedback postural control; autonomous braking; electromyography; active muscle; anticipatory postural control; seat belt pre-tension; driver braking; human body model; finite element; occupant kinematics;

   Abstract : Over 30 000 fatalities related to the road transport system are reported anually in Europe. Of these fatalities, the largest share is car occupants, even though significant improvements in vehicle safety have been achieved by the implementation of in-crash restraints and pre-crash driver support systems.
