    Sammanfattning : Cerebral palsy (CP) is the most common cause of motor disability in children and adolescents with a prevalence of 2-3/1000. CP is characterized by disorders of posture and movement with impairments ranging from mild to severe. The ability to control posture is an important prerequisite for all voluntary movements.

    Nyckelord :Medicin Teknik; Medicine Technology; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; 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.

  3. 3. Wrist and thumb joint postures and motions: Measurements using electrogoniometry and EMG

    Författare :Per Jonsson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Wrist joint; Finger joint; Electromyography; Accuracy; Electrogoniometry; Input device; Information and communication technology; Mobile phone; Muscle activity; Posture; Thumb; Wrist;

    Sammanfattning : Correct measurements of the joints’ extreme postures, velocity and repetitiveness are important for studies of the origin of musculoskeletal disorders. Posture measurements of wrist and thumb joints may also provide insights into input device designs that may reduce effort and/or facilitate productivity. LÄS MER

    Sammanfattning : Time to market is a critical success factor in todays business environment. The challange is to reduce the development cycle without sacrificing the performance and quality of products and production systems. LÄS MER

  5. 5. Computer Manikins in Evaluation of Manual Assembly Tasks

    Författare :Dan Lämkull; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; computer manikin software; virtual ergonomics; manikin appearance; digital human modelling; ergonomics evaluation; posture wizard; working posture;

    Sammanfattning : Digital human modelling (DHM) tools have been introduced in industry to facilitate a faster and more cost efficient design process. The research in this thesis is directed towards the DHM-tool-users’ needs and the objective is to identify difficulties and shortcomings, and identify requirements for improving the output of DHM-simulations.
