A STUDY ON ABILITY OF THE HANDICAPED OLDER

(1)利用肌电频谱分析和心电图RR间期变异性分析，探讨呼吸机阈值(VT)附近三种恒定运动水平的特征。受试者为11名健康男大学生(年龄20~25岁)。肌电总PSD在20~200 Hz的变化在+20VT水平高于VT水平或-20VT水平。在+20VT水平下，100-150 Hz和150-200 Hz频段肌电的PSD%增加幅度大于VT水平和-20VT水平。RR间期变异性的HF分量与负荷成正比下降，而L/H比值在3个恒定运动水平下无此变化趋势。(2)本研究旨在探讨手杖长度对偏瘫患者GATE的影响。对5例老年偏瘫患者分别用3种不同的拐杖长度行走3次，测量健侧足跟至患侧足尖距离、拐杖至患侧足尖距离、拐杖与足的步长。这些指标有显著差异。仅躯干倾斜角度随拐杖长度增加而增加。(3)观察9例偏瘫患者坐位至站位时肌张力的变化。5名受试者站立深呼吸时，患肘屈曲角度约为7位数。

(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.
