Abstract: Objective To evaluate the role of stimulation training of semicircular canal of SRM-IV vertigo diagnosis and treatment system in the rehabilitation treatment and efficacy evaluation of sudden deafness complicated with vertigo. 
Methods A total of 38 patients with sudden deafness and vertigo were selected and divided into control group (n=12), treatment group one (n=13) and treatment group two (n=13) according to random envelope method. The control group was treated with drugs, treatment group one was treated with drugs and vestibular rehabilitation training, and treatment group two was treated with stimulation training of semicircular canal on the basis of drug treatment and vestibular rehabilitation training. At 1 week, 2 weeks and 4 weeks after treatment, positive-to-negative conversion rate of rotation test, dizziness handicap inventory (DHI) score and self-rating anxiety scale (SAS) score of the three groups was compared. 
Results Compared with the control group and treatment group one, the positive-to-negative conversion rate of rotation test in treatment group two significantly increased at 2 and 4 weeks after treatment (P＜0.05). With the prolongation of treatment time, the DHI scores and the SAS scores of the three groups showed a gradually decreasing trend, with treatment group two showing the most significant decrease, and the differences in interaction between groups, time points, and time points between groups were statistically significant (P＜0.05). 
Conclusion The high-intensity vestibular function training of the SRM-IV vertigo diagnosis and treatment system plays a certain role in the treatment and evaluation of sudden deafness complicated with dizziness, showing good therapeutic effect and patient compliance, which is, therefore, worthy of popularization and application in clinical practice.
