The balance function of the patients with benign paroxysmal positional vertigo during standing / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#The purpose of the study was to investigate the balance function of the patients with benign paroxysmal positional vertigo (BPPV) during standing.@*METHOD@#In this study 41 patients with posterior semicircular canal BPPV (PC BPPV) and 11 patients with horizontal semicircular canal BPPV (HC BPPV) were recruited. Dynamic balance during standing was measured in Sensory Organization Test (SOT). Static balance during standing was measured in modified Clinical Test of Sensory Interaction and Balance (mCTSIB). Data of BPPV patients were compared to that from 44 normal controls.@*RESULT@#Scores of the patients with PC BPPV were lower than that of the normal controls in the last three test conditions of SOT. Patients with PC BPPV demonstrated greater sway velocity in stance on foam with eyes open and eyes closed in mCTSIB. No postural deficit was observed in neither SOT nor mCTSIB when the patients with HC BPPV were compared to the normal controls.@*CONCLUSION@#Disorders of the horizontal semicircular canal do not influence postural control. Both dynamic and static posturography can detect the postural imbalance caused by posterior semicircular canal dysfunction.

Postural stability after head-shaking in the healthy young individuals / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To investigate the postural stability after head-shaking in the normal young individuals.@*METHOD@#Twenty-eight normal young individuals were taken the static posturography under 4 standing conditions including (T1) head center and eye open (EO), (T2) head center and eye closed, (T3) after head-shaking and EO, (T4) after head-shaking and EC. The sway velocity (SV) of center of pressure under feet in each testing condition was recorded as parameter and each test protocol was 30 s.@*RESULT@#All examinee did not fall in each testing condition. (1) The SV increased (4.60 +/- 6.36) % after head-shaking in the EO condition, while the (8.86 +/- 8.27) % was demonstrated in the EC condition. There was significant difference between these two degrees of increase (t = 2.759, P < 0.01). (2) In static head orientation, the SV of EC (T2) increased (9.83 +/- 5.10)% compared with the SV of EO condition (T1). However, the SV of EC (T4) increased (14.05 +/- 6.89) % compared with the SV of EO condition (T3) after head-shaking. And there was significant difference between these two degrees of increase (t = 2.772, P < 0.01).@*CONCLUSION@#The stimuli of head-shaking that interrupted input from vestibular end organ can affect the function of vestibulospinal reflex in healthy young individual, especially when the visual input was interrupted simultaneously. In order to keeping balance after head-shaking, there was a complex mechanism sensory reorganization even in the normal young subject.

Individualized integrated therapy on patients with vertigo / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To explore the treatment of patients with vertigo by the integrated therapy including the drug, surgery and rehabilitation exercise and to investigate the establishment of individualized integrated therapy on patients with vertigo.@*METHOD@#One hundred and fifty-eight patients with peripheral vestibular vertigo were taken the individualized integrated therapy of vertigo (IITV). In first step of IITV, according to the etiology of vertigo, the therapy protocols were personally designed including drug, surgery or rehabilitation exercise. In second step of IITV, the patients who did not achieve effective treatment were followed-up and status of vestibular compensation and model of sensory organization in stance balance were re-evaluated. Then, the adjusted therapy protocol was designed by using drug, surgery or rehabilitation exercise comprehensively. The outcome assessment methods included the vestibular symptom index (VSI), balance assessment and dizziness handicap inventory (DHI).@*RESULT@#The result of VSI showed that there were significant difference (P < 0.01) between the post-therapy and pre-therapy in the symptoms except the headache. Both results of timed balance test and foam posturography showed that the postural stability was improved after IITV (P < 0.01). The total DHI score improved 15.97 after therapy and there were significant difference (P < 0.01) of total DHI score between the post-therapy and pre-therapy. The total effective rate of IITV was 91.14% in these patients with vertigo.@*CONCLUSION@#To treat patients with vertigo effectively, it was necessary to design the individualized integrated therapy protocol which applied the methods of drug, surgery and rehabilitation exercise comprehensively on the base of etiology of vertigo, status of vestibular compensation and model of sensory organization.
