步態(tài)分析（Gait Analysis）是以實驗動物為研究對象，根據(jù)不同實驗?zāi)康倪x取相應(yīng)的動物疾病模型或造成該疾病模型，通過觀察并記錄實驗動物在該疾病狀態(tài)下的步態(tài)行為學(xué)改變，對相應(yīng)步態(tài)參數(shù)進行客觀、精細(xì)、全面地分析統(tǒng)計，進而對動物模型的藥效學(xué)和（或）毒理學(xué)評價提供科學(xué)性實驗依據(jù)。目前步態(tài)分析已廣泛應(yīng)用于老年性疾病，如帕金森氏?。ɑ艔埐綉B(tài)）、皮質(zhì)脊髓束病變（痙攣性偏癱步態(tài)和痙攣性截癱步態(tài)）、雙側(cè)額葉病變（失用步態(tài)）、額葉（皮質(zhì)或白質(zhì)）病變（小步態(tài)）、骨髓損傷性病變（剪刀步態(tài)）、錐體外系病變（慌張步態(tài)和扭曲、奇異步態(tài)）、小腦病變（共濟失調(diào)步態(tài)）、小腦病變（舞蹈樣步態(tài)）、酒精或巴比妥類中毒（醉酒步態(tài)）、心因性疾?。Y步態(tài)）的研究。
