  1. 11. Standing in children with bilateral spastic cerebral palsy : aspects of muscle strength, vision and motor function

    Författare :Cecilia Lidbeck; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The movement and posture disorder of cerebral palsy (CP) is presumed to mainly be a consequence of the motor disorder, but accompanying disturbances with sensations and perception have also been suggested to influence motor function. The aim was to investigate factors influencing standing posture in children with bilateral spastic CP (BSCP) with varying standing abilities. LÄS MER

  3. 12. Effects of Ageing and Physical Activity on Regulation of Muscle Contraction

  4. 13. Muscle function and physical activity in pre-pubertal school children

    Författare :Susanna Stenevi Lundgren; Ortopedi - klinisk och molekylär osteoporosforskning; []

    Sammanfattning : Background: Regular participation in physical activity or organized exercise is regarded as one important lifestyle factor that could improve musculoskeletal health, fitness and body composition. For children and adolescents physical activity is important not only in training of the neuromuscular system, coordination and balance, but in a wider perspective, for adopting a lifestyle that possibly reduces the risk of coronary artery disease, obesity, osteoporosis and other contributors to morbidity and mortality in the population.
