Non-perceived lower limb static tremor visualization and quantitative analysis system

An unperceived lower limb static tremor visualization and quantitative analysis system comprises a sole dynamic deformation signal acquisition module, a lower limb tremor signal extraction module, a lower limb tremor signal analysis module, a feature extraction module, a signal analysis visualization module, a feature analysis module and a database updating module. The method comprises the following steps: acquiring sole dynamic deformation signals of two lower limbs of a patient in an unperceived state, extracting lower limb tremor signals, analyzing the lower limb tremor signals, extracting quantitative characteristics contained in analysis, and performing visualization processing; performing visualization processing on a data analysis result; the two visual results are respectively diagnosed by professional doctors and a feature analysis module, and diagnosis results are respectively output after the diagnosis is completed; updating the feature database according to needs; visual and quantitative analysis
