We evaluated the diaphragmatic excursion, volumetric measurement, maximal inspiratory pressure (PI(max)), lung function tests (forced vital capacity-FVC, forced expiratory volume in the first second-FEV1, mean forced expiratory flow between 25 and 75% of the FVC maneuver-FEF(25-75%), peak expiratory flow-PEF and maximal voluntary ventilation-MVV), displacement of the domes diaphragmatics with ultrasonography and inspiratory capacity, the MAS scale (Motor Assessment Scale) in 20 hemiplegic patients volunteers and eight controls. In right-side hemiplegia, movement was 4.97 ± 0.78 cm and 4.20 ± 1.45 cm for the right and left domes of the diaphragm, respectively, whereas these values were 4.42 ± 0.92 cm and 4.66 ± 1.17 cm in left-side hemiplegia. PI(max) was -48.75 ± 27.5 cmH2O in right-side hemiplegic patients and -74.17 ± 13.57 cmH2O in left-side hemiplegic patients. Right-side hemiplegia exhibited greater impairment of the respiratory muscles than left-side hemiplegia due to the physiologic positioning of the domes of the diaphragm which may be compromised for hemiplegia.
我们评估了膈肌的运动幅度、容量测量、最大吸气压力（PI(max)）、肺功能测试（用力肺活量-FVC、第一秒用力呼气量-FEV1、FVC 用力呼气中期 25%至 75%平均流速-FEF(25-75%)、呼气峰流速-PEF 和最大自主通气量-MVV）、超声膈肌穹顶位移和吸气容量，以及 20 名偏瘫患者志愿者和 8 名对照组的 MAS 量表（运动评估量表）。在右侧偏瘫中，右侧和左侧膈肌的运动幅度分别为 4.97 ± 0.78cm 和 4.20 ± 1.45cm，而在左侧偏瘫中，这些值分别为 4.42 ± 0.92cm 和 4.66 ± 1.17cm。PI(max)在右侧偏瘫患者中为-48.75 ± 27.5cmH2O，在左侧偏瘫患者中为-74.17 ± 13.57cmH2O。由于膈肌穹顶的生理定位，右侧偏瘫比左侧偏瘫更易导致呼吸肌受损，这可能会使偏瘫患者的呼吸功能受到影响。
