2. 1. Is seeing just believing? Measurement properties of visual assessment of Postural Orientation Errors (POEs) in people with anterior cruciate ligament injury

   Author : Jenny Älmqvist Nae; Institutionen för hälsovetenskaper; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; knee injury; Lower extremity; Anterior Cruciate Ligament; orientation spatial; Postural orientation; Performance-based measures; Reproducibility of results; Hop performance; Patient reported outcome measures;

   Abstract : Rupture of the anterior cruciate ligament (ACL) is a common knee injury among young physically active populations. The injury results in impaired physical functions, such as joint instability, limitations in daily activities and sport-specific activities, and worse movement quality, e.g., altered postural orientation.

4. 2. Visual Flow Display for Pilot Spatial Orientation

   Author : Lars Eriksson; Claes von Hofsten; David Lee; Uppsala universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Optic flow; visual flow; peripheral vision; spatial orientation; spatial disorientation; postural control; somatogravic illusion; human centrifuge; flight displays; head-up display; head-mounted display; Psychology; Psykologi; Psychology; psykologi; Psykologi;

   Abstract : Pilot spatial disorientation (SD) is a significant cause of incidents and fatal accidents in aviation. The pilot is susceptible to SD especially in low visibility when the visual system is deprived of information from outside the cockpit. 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. On the role of transversus abdominis in trunk motor control

   Author : Martin Eriksson Crommert; Peter Engfeldt; Alf Thorstensson; Maria Ekblom; Birgitta Öberg; Örebro universitet; []
   Keywords : transversus abdominis; trunk muscles; EMG; intramuscular; IAP; motor control; postural control; spine stability; postural demand; MEDICINE; MEDICIN; Medicin; Medicine;

   Abstract : All trunk muscles are important contributors to spine stability. However, the deepest abdominal muscle, transversus abdominis (TrA), with its characteristically horizontal fibre orientation seems to serve a unique function in trunk motor control. READ MORE
