目的:分析良性阵发性位置性眩晕( BPPV)患者变位试验中反转相眼震的参数特征,探讨其临床意义和产生机制。方法 BPPV患者183例,其中后半规管管石症( posterior semicircular canalithasis, PSC-Can)108例(59.0%),水平半规管管石症(horizontal semicircular canalithasis, HSC-Can)55例(30.1%),水平和后半规管的壶腹嵴顶结石症(semicircular canal cupulolithiasis, SC-Cup)15例(8.2%),上半规管管石症(anterior semicircular canalithasis ,ASC-Can)5例(2.7%)。应用视频眼震图仪记录变位试验诱发的眼震,分析比较Dix-Hallpike试验各头位的垂直眼震以及滚转试验各头位水平眼震的方向、强度、时间等参数特点。结果15例SC-Cup和5例ASC-Can患者均未见反转相眼震;108例PSC-Can患者在Dix-Hallpike试验患侧悬头位诱发向上的垂直眼震(第一相眼震)消失之后,其中54例(50.0%)出现向下的垂直眼震(反转相眼震),其第一相眼震与反转相眼震的潜伏期、持续时间、眼震强度分别为[(2.00±1.10) s,(3.54±1.42) s]、[(16.27±4.95) s,(61.65±33.69) s]、[(51.80±25.25)°/s,(10.65±6.29)°/s];55例HSC-Can患者在滚转试验患侧转头位诱发与转头方向相同的水平眼震(第一相眼震)消失之后,其中43例(78.2%)出现与转头方向相反的水平眼震(反转相眼震),其第一相眼震与反转相眼震的潜伏期、持续时间、眼震强度分别为[(1.67±1.07)s,(3.57±1.89) s]、[(25.19±9.74) s,(70.48±40.26) s]、[(68.47±30.18)°/s,(11.22±8.78)°/s]。通过配对t检验分别比较PSC-Can及HSC-Can患者第一相眼震与反转相眼震的潜伏期、眼震强度及持续时间,其差异均具有统计学意义( P值均<0.05)。通过独立样本t检验比较这两组管石症患者中有反转相眼震者与无反转相眼震者第一相眼震的参数,其中眼震强度的差异有统计学意义(P值均<0.05);而眼震潜伏期、持续时间的差异则均无统计学意义(P值均>0.05)。结论反转相眼震在PSC-Can及HSC-Can患者中很常见,是其临床特征之一,分别出现在Dix-Hallpike试验患侧悬头位及滚转试验向患侧转头位;第一相眼震越强,越容易诱发反转相眼震;第一相眼震的潜伏期和持续时间较反转相眼震短,但眼震强度较反转相眼震强。正确认识反转相眼震有助于避免其对临床上耳石定位及复位产生干扰,其产生机制可能类似于前庭后象眼震,是前庭后象反应在BPPV患者的另一种表现形式。
目的:分析良性陣髮性位置性眩暈( BPPV)患者變位試驗中反轉相眼震的參數特徵,探討其臨床意義和產生機製。方法 BPPV患者183例,其中後半規管管石癥( posterior semicircular canalithasis, PSC-Can)108例(59.0%),水平半規管管石癥(horizontal semicircular canalithasis, HSC-Can)55例(30.1%),水平和後半規管的壺腹嵴頂結石癥(semicircular canal cupulolithiasis, SC-Cup)15例(8.2%),上半規管管石癥(anterior semicircular canalithasis ,ASC-Can)5例(2.7%)。應用視頻眼震圖儀記錄變位試驗誘髮的眼震,分析比較Dix-Hallpike試驗各頭位的垂直眼震以及滾轉試驗各頭位水平眼震的方嚮、彊度、時間等參數特點。結果15例SC-Cup和5例ASC-Can患者均未見反轉相眼震;108例PSC-Can患者在Dix-Hallpike試驗患側懸頭位誘髮嚮上的垂直眼震(第一相眼震)消失之後,其中54例(50.0%)齣現嚮下的垂直眼震(反轉相眼震),其第一相眼震與反轉相眼震的潛伏期、持續時間、眼震彊度分彆為[(2.00±1.10) s,(3.54±1.42) s]、[(16.27±4.95) s,(61.65±33.69) s]、[(51.80±25.25)°/s,(10.65±6.29)°/s];55例HSC-Can患者在滾轉試驗患側轉頭位誘髮與轉頭方嚮相同的水平眼震(第一相眼震)消失之後,其中43例(78.2%)齣現與轉頭方嚮相反的水平眼震(反轉相眼震),其第一相眼震與反轉相眼震的潛伏期、持續時間、眼震彊度分彆為[(1.67±1.07)s,(3.57±1.89) s]、[(25.19±9.74) s,(70.48±40.26) s]、[(68.47±30.18)°/s,(11.22±8.78)°/s]。通過配對t檢驗分彆比較PSC-Can及HSC-Can患者第一相眼震與反轉相眼震的潛伏期、眼震彊度及持續時間,其差異均具有統計學意義( P值均<0.05)。通過獨立樣本t檢驗比較這兩組管石癥患者中有反轉相眼震者與無反轉相眼震者第一相眼震的參數,其中眼震彊度的差異有統計學意義(P值均<0.05);而眼震潛伏期、持續時間的差異則均無統計學意義(P值均>0.05)。結論反轉相眼震在PSC-Can及HSC-Can患者中很常見,是其臨床特徵之一,分彆齣現在Dix-Hallpike試驗患側懸頭位及滾轉試驗嚮患側轉頭位;第一相眼震越彊,越容易誘髮反轉相眼震;第一相眼震的潛伏期和持續時間較反轉相眼震短,但眼震彊度較反轉相眼震彊。正確認識反轉相眼震有助于避免其對臨床上耳石定位及複位產生榦擾,其產生機製可能類似于前庭後象眼震,是前庭後象反應在BPPV患者的另一種錶現形式。

Objective To investigate the clinical significances and formation mechanism by analyzing the characteristics of the reverse phase nystagmus parameters from benign paroxysmal positional vertigo ( BPPV ) positioning test.Methods There were 183 cases with BPPV , including 108 cases (59.0%) of posterior semicircular canal canalthasis , 55 cases ( 30.1%) of horizontal semicircular canal canalthasis, and 15 cases(8.2%) of horizontal and posterior semicircular canal cupulolithiasis and 5 cases (2.7%) of anterior semicircular canalithasis .The video-nystagmograph was utilized in positioning tests to induce nystagmus.The direction , intensity , time parameters characteristic of vertical nystagmus in Dix-Hallpike test and horizontal nystagmus in roll test were analyzed and compared.Results There were no reversal phase nystagmus in 15 cases of semicircular canal cupulolithiasis and 5 cases of anterior semicircular canalithasis .After the disappearance of vertical nystagmus which induced by hanging position ( the first phase nystagmus ) in 108 cases of posterior semicircular canalithasis of Dix-Hallpike test , there was 54 cases ( 50.0%) of posterior semicircular canal canalthasis displayed downward vertical nystagmus (reverse phase nystagmus ) .The latency, duration time and intensity of the first phase nystagmus and reverse phase nystagmus were [(2.00 ±1.10)s, (3.54 ±1.42)s], [(16.27 ±4.95)s, (61.65 ±33.69) s] and [ ( 51.80 ±25.25 ) °/s, ( 10.65 ±6.29 ) °/s ] respectively; 43 cases ( 78.2%) of horizontal semicircular canal canalithasis displayed the opposite to turning head ( reverse phase nystagmus ) after the horizontal nystagmus , similar with turning head disappeared in Roll test.The latency, duration time and intensity of the first phase of nystagmus and reverse phase nystagmus were [(1.67 ±1.07) s, (3.57 ± 1.89)s], [(25.19 ±9.74) s, (70.48 ±40.26) s] and [(68.47 ±30.18)°/s, (11.22 ±8.78)°/s] respectively.Comparing with the latency , duration time , intensity of first phase nystagmus and reverse phase nystagmus of posterior and horizontal semicircular canal canalithasis , the differences had statistical significances (P<0.05).Comparing with the first phase nystagmus of reverse phase and no reverse phase nystagmus canalithasis , the difference of nystagmus intensity had statistical significances ( P<0.05); but the differences of latency and duration of nystagmus had no significant difference ( P>0.05).Conclusions It is common in PSC-Can and HSC-Can patients that reverse phase nystagmus is one of the clinical features of canalithasis.It appears in side head position of Rolling test or the hanging of Dix-Hallpike test.More power of the first phase nystagmus has , reverse phase nystagmus will be induced much easier.In comparison of the reverse phase nystagmus , the first phase nystagmus has the shorter incubation and duration , but it has more power .It is helpful to avoid interruptions of clinical statolith positioning and reset since we recognize the reverse phase nystagmus.The mechanism might be similar to the vestibular mirror image nystagmus.It is another form of the vestibular mirror image nystagmus in BPPV patients.
