The vital capacity (VC), forced expiratory volume in one second (FEV1) and expiratory time (ET) of eight cerebral-palsied children aged between five and 12 years was measured, when seated in a regular sling-type wheelchair and in an adaptive seating system. The results showed a 57.7 per cent increase in VC, a 51.6 per cent increase in FEV1 as a percentage of VC, and a 55 per cent increase in ET in the adaptive seating system compared with the standard wheelchair. These results have important implications for speech, sitting for prolonged periods and prevention of hypoxia and pulmonary hypertension.
对8名年龄在5至12岁之间的脑瘫儿童，分别在他们坐在普通吊带式轮椅和适应性座椅系统中时，测量了肺活量（VC）、一秒用力呼气量（FEV1）和呼气时间（ET）。结果显示，与标准轮椅相比，在适应性座椅系统中，肺活量增加了57.7%，一秒用力呼气量占肺活量的百分比增加了51.6%，呼气时间增加了55%。这些结果对言语、长时间坐姿以及预防缺氧和肺动脉高压具有重要意义。
