Abstract
Objective:To investigate the significance of the reverse phase nystagmus for the diagnosis of benign paroxysmal positional vertigo when going on the positioning test. Method:During the positioning test，there are 26 cases with reverse phase nystagmus in the 118 BPPV patients，note and analyse their nystagmus characteristics，then combine their disease history，to diagnose the affected side of the BPPV，and following with the corresponding treat of canalith repositioning procedure（CRP）. Result:All the 26 cases with reverse phase nystagmus are the BPPV patients of horizontal semicircular postalcanalithasis，in which，RHSC-pCan for 15 cases，LHSC-pCan for 11 cases，with the treat of CRP，the significant effectivities are 4 cases，effectivities 15，uneffectivities 7，after single factor chi-square test，χ²=7.46,P< 0.05.Conclusion:For the BPPV cases with reverse phase nystagmus during the positioning test，their efficacy difference of the CRP is significant statistically，that is the CRP treat is effective, the therapeutic diagnosis is established, which contributes to the analysis and judgment for the affected side of the semi-circular canals.
