NCT03420625

Brief Summary

In this study, four different devices which stimulate the blood in the lower extremities are used in ten healthy persons while measuring the blood flow with ultrasound. The aim is to study the haemodynamic effects in the lower extremities of each modality and also to compare those effects between the four modalities in order to identify those which most effective than the others.

Outcome Measures

Primary Outcomes (4)

  • Blood Flow - Peak Systolic Velocity (cm/Sec)

    With the use of Doppler Ultrasound Peak systolic velocity (cm/sec) is assessed in the popliteal vein.

    up to one hour in total

  • Blood Flow - Time-averaged Mean Velocity (cm/Sec)

    With the use of Doppler Ultrasound Time-averaged mean velocity (cm/sec) is assessed in the popliteal vein.

    up to one hour in total

  • Blood Flow - Volume Flow (ml/Min)

    With the use of Doppler Ultrasound Volume flow (ml/min), is assessed in the popliteal vein.

    up to one hour in total

  • Blood Flow - Ejected Volume Per Individual Stimulus (ml)

    With the use of Doppler Ultrasound Ejected volume per individual stimulus (ml) is assessed in the popliteal vein.

    up to one hour in total

Secondary Outcomes (1)

  • Tolerability to IPC and NMES According to Visual Analogue Scale 0-10

    one minute
