A STUDY ON ABILITY OF THE HANDICAPED OLDER

(1)利用心电图肌电图和RR间期变异性的频谱分析，探讨了三种恒定运动水平在通气阈值（VT）附近的特征。研究对象为11名20 ~ 25岁的健康男学生。肌电图上总PSD从20Hz到200Hz的变化显示，+20VT水平的值高于VT水平或-20VT水平的值。+20VT水平工作负荷下100 ~ 150hz和150 ~ 200hz频段肌电信号的% PSD比-20VT和-20VT水平工作负荷下增加得更多。RR区间变异性的HF分量随负荷的增加呈快速下降趋势，而L/H比在3个恒定运动水平下没有这种趋势。(2)本研究旨在探讨手杖长度对偏瘫患者的影响。5例老年偏瘫患者步行3次，使用3种不同长度的手杖，测量健全侧足跟到患侧足顶的距离、手杖到患侧足顶的距离、手杖与足的步幅。这些指标无显著性差异。随着甘蔗长度的增加，只有树干倾斜的角度增加。(3)研究了9例偏瘫患者从坐姿到站立时肌肉张力的变化。5例受试者站立并深呼吸时，患肘屈曲角度减小约7度。

(1) A study was performed to investigate characteristics of three constant exercise levels around the ventilatory threshold (VT) using spectral analysis of EMG and RR interval variability of ECG. The subjects were 11 healthy male students (ranging in age from 20 to 25 years). Changes in Total PSD from 20Hz to 200Hz on EMG showed a higher value at the +20VT level than at the VT level or -20VT level. The % PSD of EMG at the band of 100-150Hz and 150-200Hz increased in the work load at the +20VT level more than at the VT level or -20VT level. HF component of the RR interval variability showed a rapid decrease in proportion to load, whereas there was no such trend for the L/H ratio in the 3 constant exercise levels.(2) This study is to investigate the influence of cane length for gate as hemiplegic patient. When five older hemiplegic patients walked 3 times used three different cane length and were measured distance from heel of the sound side to top of foot of affected side, from cane to top of foot of affected side, stride of cane and foot. Nosibnificant different was these indexes. Only the angle of trunk tilt was increased as length of cane.(3) A study was to investigate the changes of muscle tone from sitting to standing in 9 hemiplegic patients . As 5 subject standed with deep breathing, flection angle of affected elbow dicreaced about 7 digree.
