Abstract: Objective To explore the assessment methods of persistent postural-perceptual dizziness(PPPD).Methods A total of 39 patients with PPPD were enrolled as PPPD group,compare with 36 cases with unilateral sudden sensorineural hearing loss(SSHL) with vertigo.The clinic data,DHI/NEO-FFI/SSRC,auditory and vestibular function(bithermal caloric test,vestibular evoked myogenic potential)tests were collected for all the subjects and compared between groups.Results There were statistical differences between two groups in DHI/NEO-FFI/ SSRC (P＜0.05).13 cases of PPPD with mild or moderate sensorineural hearing loss,36 cases of SSHL with severe or extremely severe sensorineural hearing loss;double temperature test and VEMP normal derivation rates of PPPD were significantly higher than SSHL (P＜0.05).Conclusion Neurotic and introverted personality traits are found to be risk factors for PPPD.Patients with PPPD are prone to anxiety.PPPD has a great impact on the social activities and life quality of patients.
