Impedance Plethysmography was used to measure the perfusion changes and venous clearance in the lower leg, knee, thigh and buttock that was produced by operation of a pulsating seat cushion that may reduce the detrimental hemodynamic effects of prolonged driving. The grouped mean indices of arterial perfusion increased significantly (P under 0,05), in all segments studied, following a 5 minute activation of the seat cushion. The cushion assisted venous clearance in all segments of the leg during each inflation cycle. This device may be desirable to reduce fatigue and incraese performance during prolonged driving.
