    Sammanfattning : Categories and frequencies of leisureactivities employed by 156 randomly selected males and females aged 40-44, 50-54, 60-64 were investigated by structured interviews and were related to leisuresatisfaction, to experienced health and socio-economic status. In equal numbers (15) of males and females from each group and in 24 males (60 +_6 years) with intermittent claudication (Cl) isokinetic plantar flexion performance was investigated with registrations of peak torque (PT), contractional work (CW), active range-of-motion (RoM) and integrated electromyograms from all threee triceps surae heads.

    Sammanfattning : Background: The heel-raise test (HRT) is used in clinical practice and research to assess the triceps suare (TS) muscles. The test involves repetitive unilateral heel-raises in upright stance. The test is administered with the knee straight for gastrocnemius medialis (GM) and lateralis (GL), and with the knee bent for soleus (SOL). LÄS MER

  3. 3. Post-polio syndrome - physiotherapeutic analysis and interventions

    Författare :Katarina Skough; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Post-polio syndrome;

    Sammanfattning : This thesis presents four studies focusing on outcomes of gait performance using gait analysis and/or the Six-minute-walk test (6MWT), in patients with post-polio syndrome (PPS). Further, resistance training in combination with Coenzyme Q10 (Q10) and intravenous immunoglobulin treatment (IvIg) in PPS patients was evaluated. LÄS MER

  4. 4. Analysis of body motions based on optical markers. Accuracy, error analysis and clinical applications

    Författare :Roy Tranberg; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Instrumented gait analysis Motion analysis Skin markers Optical tracking system;

    Sammanfattning : This thesis aims to evaluate the influence of soft-tissue artefacts on analyses of body motions based on optical markers. A second aim is to apply instrumented gait analysis in clinical situations. Introduction: Instrumented gait analysis has been used since 1960 as a clinical evaluation/investigative tool at orthopaedic clinics. LÄS MER

  5. 5. Evaluation of surface electromyography and aspects of muscle strength in persons without motor impairment and in children with hemiplegic cerebral palsy

    Författare :Barbro Larsson; Katharina Stibrant-Sunnerhagen; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Impaired muscle function significantly affects persons with Cerebral Palsy (CP), affects that include muscle strength, fatigue and endurance. This thesis evaluates a test method, an endurance test, and estimates aspects of muscle fatigue and muscle endurance in persons without impaired muscle function and in children with CP. LÄS MER
