ABSTRACT:
A method of finding a thigh support for most optimal blood circulation in the lower extremities of a seated person consisting of measuring a blood-circulation parameter such as blood-flow velocity through the lower extremities of a seated person under different seating conditions, including those with or without the use of any thigh-supporting means. It has been proven that with the use of a thigh-supporting means, the measured blood-circulating parameter was much better than in a person seated without the use of a thigh-supporting means. Blood-flow velocity through the lower extremities of a person seated on the aforementioned seating device was measured by determining the Doppler shift in the frequency of returning ultrasound waves.
