Abstract：
The purpose of this study was to investigate the psychological impact of various positionings in subjects with cerebral palsy (CP). The participants were 17 individuals with severe motor and intellectual disability due to CP. They began in a sitting position in their wheelchair, and were placed consecutively in prone or supine positions, with no intervals between placements. Physiological observations were made in each position, and included salivary α-amylase activity, pulse, percutaneous oxygen saturation, respiratory rate, learance or not of airway secretions, and occurrence or not of adverse events. Salivary α-amylase activity values were higher in the prone position than in the baseline and supine positions (p<0.05). Clearance of airway secretions was significantly more prevalent in the prone position than in the baseline and supine positions (p <0.05). The participants\' pulse was significantly lower in the supine and prone positions than in the baseline position (p<0.05). Greater prevalence of airway secretion clearance and significantly higher stress levels as indicated by saliva amylase were observed in the prone position than in the other two positions. Therefore, when such patients are placed in a prone position, close attention to airway management and the potential for psychological stress may be necessary.
摘要：
这项研究的目的是调查各种姿势对脑瘫（CP）受试者的心理影响。参与者是17名因CP而严重运动和智力残疾的人。他们开始坐在轮椅上，并连续放置在俯卧或仰卧位置，放置之间没有间隔。在每个位置进行了生理观察，包括唾液α-淀粉酶活性，脉搏,经皮氧饱和度,呼吸频率,是否有呼吸道分泌物，以及不良事件的发生与否。唾液α-淀粉酶活性值在俯卧位高于基线位和仰卧位(p<0.05)。俯卧位的气道分泌物清除明显比基线位和仰卧位更为普遍(p<0.05)。参与者的脉搏在仰卧位和俯卧位明显低于基线位(p<0.05)。与其他两个位置相比，在俯卧位中观察到更高的气道分泌清除率和唾液淀粉酶所表明的明显更高的压力水平。因此,当这些病人处于俯卧位时，密切关注气道管理和潜在的心理压力可能是必要的。
