It has been shown that during head-down tilting at an angle of -30 degrees occlusion of the four limbs by 70 mm Hg relieved unpleasant symptoms. According to rheoencephalography, cerebral blood flow decreased to the level normally seen in the supine position. During a prolonged head-down tilting at an angle of -15 degrees intermittent occlusion of only lower limbs by 60--30 mm Hg proved more effective.
研究表明，在头部向下倾斜30度时，用70毫米汞柱阻断四肢可缓解不适症状。根据脑血流图，脑血流量降至仰卧位时的正常水平。在长时间头部向下倾斜15度时，仅用60 - 30毫米汞柱间歇性阻断下肢被证明更有效。
