The utility model relates to a portable
gait analysis device based on a
small animal, which comprises a slide rail frame, a slide rail, a slide rail, a slide rail, a slide rail, a slide rail, a slide rail, a slide rail and a slide rail, the plurality of force measuring tables are used for measuring the dynamic three-dimensional force data of the foot sole of the animal; the flexible
pressure sensor is packaged on the force measuring table, and the flexible
pressure sensor is used for measuring a pressure image of the whole
walking gait process of the four limbs of the
experimental animal; a plurality of force measuring tables are detachably installed on the sliding rail frame according to requirements. The animal movement posture can be obtained, the blank of lack of animal
gait, behavior ability research and
disease state evaluation and diagnosis instruments at present is effectively filled up, and the defects of complex examination conditions, difficulty in capturing movement tracks, complex analysis process and the like during animal overall condition examination are overcome.
