    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; psykologi;

    Sammanfattning : An acoustic environment contains sounds from various sound sources, some generally perceived as wanted, others as unwanted. This thesis examines the effects of wanted and unwanted sounds in acoustic environments, with regard to masking, stress recovery, and speech intelligibility. LÄS MER

  4. 18. Facilitation of recovery after ischaemic stroke : early dexamphetamine and physiotherapy treatment

    Författare :Louise Martinsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Stroke; cerebral infarct; dexamphetamine; physiotherapy; recovery; safety; efficacy; pharmacokinetics; meta-analysis;

    Sammanfattning : Purpose: The overall aims of the thesis were to investigate the safety, efficacy, and pharmacokinetics of dexamphetamine (d-amph) after cerebral infarct, and the effects of different amounts of physiotherapy in combination with d-amph on recovery, early after cerebral infarct in patients with severe stroke. Patients and methods: The thesis is based on three studies on patients in the department of Neurology, Karolinska Hospital, Sweden, and on one meta-analysis based on data collected from previously published studies.
