动物步态分析系统

动物步态分析系统系统由被动步态分析系统TreadScan与主动步态分析系统RunwayScan组成。主要用于 运动神经缺损评价：采用TreadScan模块，通过对动物运动行为步态的自动识别与分析，进行运动神经区缺损情况评价。可对帕金森症、阿兹海默症、ALC、关节炎、神经肌肉及骨骼肌肉疾病进行评价。

系统说明：TreadScan采用高速摄像机（100帧/秒）以底面视角对老鼠在跑台上的步态进行自动识别与分析。

测量参数：触地/抬起，步长，步频，速度，足趾分散，足迹面积，体足距离，足间距，足迹角度，旋转与平移。

GaitScan can reliably analyze the video, and determine various characteristic parameters that are related to the pathophysiological conditions. These parameters include the stance time (paw on the belt), the swing time (paw in the air), total stride time, stride length, foot contact area size, foot pressure (measured using color intensity levels), body-foot spacing distance (distances between body and feet), foot spacing distances (distance between various feet), running speed, stride frequencies, foot coupling measures (in-phase or out-of-phase gait patterns of feet), and Sciatic Function Index related measures such as foot print placement rotation angle with body and toe spread factors (splay). Also calculated are brake time (early part of stance until the paw reaches maximum contact) and propel time (latter portion of stance when the paw is propelling the body. GaitScan also provides Whole Body Movement Information, including information about Body Rotation during walking, Body Shifting (lateral and longitudinal whole body movements) during walking. Base of support information including a new measure called Gait Angle is also provided.
