2. 1. 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

4. 2. Asymmetric lateral loading of the human trunk

   Author : Qiang-Min Huang; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Eccentric; concentric; isokinetic; electromyography; co-activation; trunk; spinal biomechanics; contraction patterns; lateral bending; lifting and lowering; balance; kinematics; postural control; IAP; support translation.;

   Abstract : The overall aim of this thesis was to characterize the biomechanics and neuromuscular control of the human trunk in response to asymmetric lateral loading. The pulling force and strength capacities as well as muscle activation patterns, trunk kinematics and postural balance in relation to lateral trunk flexion and loading were given special consideration.

5. 3. EMG and strength in trunk and hip muscles

   Author : Eva A Andersson; Alf Thorstensson; Margareta Nordin; Gymnastik- och idrottshögskolan; Karolinska Institutet; Karolinska Institutet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurophysiology; Neurofysiologi; abdominal muscles; biomechanics; electromyography; erector spinae; iliacus; iliopsoas; hip flexor muscles; locomotion; motor control; normalization; posture; psoas; quadratus lumborum; rehabilitation; running; sit-ups; strength; training exercises; u;

   Abstract : The overall aim of this thesis was to study the myouelectric activity of all major muscles involved in the movements and stabilization of the trunk, pelvis and hips during training exercises, postures, motor tasks, maximal strength performance and locomotion. By use of ultra-sound, EMG electrodes could be guided safely and accurately into muscles situated even close to the spinal column, such as psoas, quadratus lumborum and deep parts of erector spinae.

6. 4. Methods for analysis of 3D movement of the trunk during treadmill locomotion

   Author : Virgil P Stokes; Karolinska Institutet; Karolinska Institutet; []
   Keywords : human. trunk. Iocomotion. kinematics. 3D. treadmill Stockhtolm 1997;

   Abstract : Human locomotion is a common activity and although much progress has been made in the analysis and modeling of movement, we still have a rather limited understanding of the basic mechanisms of normal locomotion. A full understanding requires the integration of the underlying neural mechanisms with the 3D dynamics (kinetics + kinematics) of locomotion. READ MORE

7. 5. The Public Transport Preferences of Elderly People; A study related to individual capacity and environmental stress in service route traffic and other systems

   Author : Helena Svensson; Trafik och väg; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; walking distance; valuation; standard factors; conjoint analysis; stated preference method; trunk routes; special transport; service routes; restrictions; physical capacity; preferences; travellers; public transport; elderly people; traffic planning; Road transport technology; Vägtransportteknik;

   Abstract : Providing accessible, acceptable and appreciated public transport for elderly people is essential. This work studies the relation between elderly people’s preferences of standard factors in different public transport systems, and their physical capacity. READ MORE
