Clinical Recognition of Sensory Ataxia and Cerebellar Ataxia

Ataxia is a kind of external characteristics when the human body has poor coordination and balance disorder, it often indicates diseases in certain parts body. Many internal factors may causing ataxia; currently, observed characteristics, combined with Doctor’s personal clinical experience play main roles diagnosing ataxia. In this situation, different kinds be confused, leading to delay treatment recovery. Modern high precision medical instruments would provide better accuracy but economic cost non-negligible factor. paper, novel non-contact sensing technique used detect distinguish sensory ataxia cerebellar Firstly, Romberg’s test gait analysis data are collected by microwave platform; then, after some preprocessing, machine learning approaches have been applied train models. For test, time domain features considered, all three algorithms higher than 96%; for detection, Principal Component Analysis (PCA) dimensionality reduction, accuracies Back Propagation (BP) neural Network, Support Vector Machine (SVM), Random Forest (RF) 97.8, 98.9, 91.1%, respectively.
