1. 16. The Healthy Ageing Initiative : Prevention of falls and fractures

   Författare :Jonas Johansson; Peter Nordström; Anna Nordström; Jon Karlsson; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; prospective falls; cohort study; fall risk; gait variability; postural stability; physical activity; bone properties; objective measurements; older individuals;

   Sammanfattning : The world is currently experiencing a dramatic increase in the number of older individuals, an amount that is expected to double between 2015 and 2050. This increase will likely affect the prevalence of age-related functional impairments, such as those caused by fractures. LÄS MER

3. 17. Wearable systems and sensors for the assessment of motor control : Development and validation of methods for clinical assessment of idiopathic normal pressure hydrocephalus

   Författare :Tomas Bäcklund; Nina Sundström; Anders Eklund; Jan Malm; Kaj Lindecrantz; Umeå universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gait; step-width; heel-heigt; balance; trunk sway; idiopathic normal pressure hydrocephalus; IMU; Inter-rater reliability; kinematics; medical informatics; medicinsk informatik;

   Sammanfattning : Human gait and balance are controlled by automatic processes in the central nervous system, and in sensory and proprioceptive systems. If a disturbance occurs in any of these complex structures, it may lead to balance and gait problems. LÄS MER

4. 18. Ankle sprain : subjective and objective measures of functional impairment and treatment

   Författare :Johan Leanderson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Ankle sprain; epidemiology; postural sway; muscle torque; muscle imbalance; proprioception; joint position sense; figure-of-eight running; sick leave; ankle brace treatment; functional instability; basketball; ballet; soccer; taping; Sickness Impact;

   Sammanfattning : This thesis is based upon a series of studies were performed in order to provide more information about the etiology of late symptoms after ankle sprain, most often referred to as functional instability of the ankle joint. In a retrospective study of basketball players, the incidence of ankle sprains and the prevalence of late symptoms after such an injury were investigated. LÄS MER

5. 19. Neural control of standing posture

   Författare :Craig Tokuno; Andrew Cresswell; Alf Thorstensson; Marc Carpenter; Thomas Sinkjær; Gymnastik- och idrottshögskolan; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Medicin Teknik; Medicine Technology; Posture; motor cortex; electromyography; kinematics; H-reflex; pre-synaptic inhibition; transcranial magnetic stimulation;

   Sammanfattning : 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.

7. 20. Dynamic posturography in evaluating human equilibrium

   Författare :Torbjörn Ledin; Måns Magnusson; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : Equilibrium assessment by means of posturography can be performed ina dynamic fashion, meaning that the environment does not remainstable during the test. In the EquiTest dynamic posturography version, the support surface and the visual surround are movable, actively or in response to body movements. LÄS MER
