title: [Analysis of relation between the development of study and literatures about benign positional paroxysmal vertigo published international and domestic].
abstract: OBJECTIVE
  Benign paroxysmal positional vertigo (BPPV) is a common vestibular disorder that causes vertigo. Study of BPPV has dramatically rapid progress in recent years. We analyze the BPPV growth
  
  
  METHODS
  We searched the international data quantity year by year in database of PubMed, ScienceDirect and WILEY before 2014 respectively, then we searched the domestic data quantity year by year in database of CNKI, VIP and Wanfang Data before 2015 by selecting "Benign paroxysmal positional vertigo" as the keywords. Then we carried out regression analysis with the gathered results in above databases to determine data growth regularity and main factors that affect future development of BPPV. Also, we analyzes published BPPV papers in domestic and international journals.
  
  
  RESULTS
  PubMed database contains 808 literatures, ScienceDirect contains 177 database and WILEY contains 46 literatures, All together we collected 1 038 international articles. CNKI contains 440 literatures, VIP contains 580 literatures and WanFang data contains 449 literatures. All together we collected 1 469 domestic literatures. It shows the rising trend of the literature accumulation amount of BPPV. The scattered point diagram of BPPV shows an exponential growing trend, which was growing slowly in the early time but rapidly in recent years.
  
  
  CONCLUSIONS
  It shows that the development of BPPV has three stages from international arical: exploration period (before 1985), breakthrough period (1986-1998). The deepening stage (after 1998), Chinese literature also has three stages from domestic BPPV precess. Blank period (before the year of 1982), the enlightenment period (1982-2004), the deepening stage (after the year of 2004). In the pregress of BPPV, many outsantding sccholars played an important role in domestic scitifction of researching, which has produced a certain influence in the worldwide.
