THE COMPUTERIZED GAIT ANALYSIS SYSTEM AND THREE DIMENSIONAL ANALYSIS OF FOOT-GROUND REACTION FORCES DURING LEVEL WALKING

A S9-2 computerized gait analysis system developed by us is reported. The advantages of the system are: synchronous measurement of the forces, angles and time parameters; high efficiency, accuracy and good repeatability; low cost and easy to operate. A three dimensional analysis of the foot-ground reaction forces of 41 normal subjects during level walking was carried out by the S9-2 system and a series of normal values of parameters and characteristic curves were obtained. The mechanism of formation of the parameters and curves and the sex influence were investigated and discussed. In old subject, before the development of "cautious gait", most values of the parameters did not differ significantly from those of the young subjects, except that the centre of gravity of the body crossing the hip earlier with a slight decrease in the medio-lateral balance capacity.     

性格类型与高血压病相关性的初步探讨

近年来,现代医学正由“生物医学模式”向“生物—心理—社会医学模式”转变,重视对心理社会发病因素的探讨。高血压病(原发性高血压)是一种被公认发病与心理社会因素有关的心理生理疾患。据调查高血压病患者约有2/3具备一定的性格特征,一般认为容易焦虑激动的人易患高血压病。Buell提出A型性格(行为)与高血压
