(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.

(1)采用肌电图频谱分析和心电图RR间期变异性研究了阈下三个恒定运动水平的运动特征。受试者为11名健康男性学生（年龄20 - 25岁）。在20 Hz ~ 200 Hz范围内，肌电图的总PSD在+20VT水平上的变化值高于VT水平和-20VT水平。100- 150 Hz和150- 200 Hz频段的肌电功率谱密度（% PSD）在+20VT水平下比VT水平和-20VT水平下增加更多。RR间期变异性的HF分量显示出与负荷成比例的快速下降，而L/H比值在3个恒定运动水平中没有这种趋势。(2)摘要本研究旨在探讨手杖长度对中风偏瘫患者之影响。对5例老年偏瘫患者采用3种不同的手杖长度行走3次，测量健侧足跟至患侧足顶的距离、手杖至患侧足顶的距离、手杖与足的步幅。这些指标无显著性差异。只有躯干倾斜角随蔗茎长度的增加而增加。(3)观察9例偏瘫患者从坐位到站立位肌张力的变化。5例受试者深呼吸站立时患肘屈曲角度减小约7 °。
