Abstract:
Objective:To investigate the status of the vestibular function of the patients with chronic positional symptoms after peripheral acute vestibular syndrome (AVS) and the curative effect of the vestibular rehabilitation therapy (VRT). Method:Using caloric test (CT), head shaking nystagmus test (HST), cervical vestibular evoked myogenic potentials as well as ocular vestibular evoked myogenic potentials to estimate the function of semicircular canal and otolith organs. The patients with normal VEMPs are divided as Group A. Otherwise are as Group B. Both groups are treated with VRT. The curative effect is estimated by vestibular symptom index (VSI) and Berg balance scale (BBS). Result:Thirty-three of 37 patients (86.5%) had an abnormal result of CT and HST, with 23 of these patients (65.7%) had an abnormal of both test. Twenty-two patients (59.5%) were in Group A and 15 (40.5%) in Group B. Before the therapy, Group B had a higher score of the balance and dizziness symptoms of VSI (P<0.05), and Group A had a higher score of the BBS (P<0.05). After the therapy, the VSI scores of both groups dropped and scores of the BBS raised. Conclusion:Patients with chronic positional symptoms after peripheral AVS have dynamic vestibular lesions to different extents. Those with otolith organs lesions tend to have a worse function of balance. Nevertheless, patients have a better off after VRT.
