Test subjects exposed to altitude decompression without preliminary denitrogenization showed in 65-75% of cases stability or reduction of the amplitude of the H-response of a leg with subsequent painful sensations and in increase of the amplitude of the H-response in the other leg as long as they were raised to an altitude of 11,000 m. When bends developed in a leg the amplitude of the H-response in that leg decreased and in the opposite leg increased. During the descent and disappearance of painful sensations changes in the amplitude of the H-response were just the opposite. It is assumed that a decrease of the amplitude of the H-response during altitude decompression was associated with oxygen deficiency of nerve afferents and an increase--with the descending activating supraspinal effect.
在未预先进行去氮处理的情况下暴露于高空减压的试验对象中，65%至75%的病例显示，一条腿的H反射幅度保持稳定或降低，随后出现疼痛感觉，而另一条腿的H反射幅度在升至11000米高度时增加。当一条腿出现弯曲时，该腿的H反射幅度降低，而对侧腿的H反射幅度增加。在下降过程中疼痛感觉消失时，H反射幅度的变化则相反。据推测，高空减压时H反射幅度的降低与神经传入纤维的缺氧有关，而幅度增加则与下行激活的脊髓上效应有关。
