本文选48人,分2组:1组24名,15～34岁,男性12名,平均年龄24.7±5.5岁,女性12名,平均年龄21.3±7.3岁;2组24名,60～69岁,男性12名,平均年龄64.8±2.6岁,女性12名,平均年龄64.5±2.4岁。除2组有对称性听力减退(SRT 27.5dBHL)外,余均在正常范围。均作纯音及言语识别力检查及眼震电图记录①20mm视标偏斜产生20度眼运动,②自发性和凝视性眼震,③每秒位移10及20度水平闪光作视跟踪试验,每个位移速度测60秒钟。视距均为1 m,均无自发性和凝视性眼震。取中间20秒段正弦跟踪记录计分。结果:年青人组84%两种速度均现第Ⅰ型曲线,8%两种速度现Ⅱ型,4%现Ⅲ型及4%
This article selected 48 people, divided into 2 groups: a group of 24, 15 to 34 years old, 12 males, mean age 24.7 ± 5.5 years, 12 females, mean age 21.3 ± 7.3 years; 2 groups of 24, 60 to 69 years , 12 males, with an average age of 64.8 ± 2.6 years and 12 females, with an average age of 64.5 ± 2.4 years. Except the two groups had symmetrical hearing loss (SRT 27.5dBHL), the remaining in the normal range. Were made pure tone and speech recognition examination and electronystagmography ① 20mm eye deflection produced 20-degree eye movement, ② spontaneous and gaze nystagmus, ③ displacement of 10 and 20 degrees per second horizontal flash as a follow-up test, each A displacement of 60 seconds. Line of sight are 1 m, no spontaneous and staring nystagmus. Take the middle of 20 seconds sinusoidal tracking record score. Results: The young group of 84% of the two kinds of speed are the first type Ⅰ curve, 8% of the two rates are Ⅱ, 4% are Ⅲ and 4%
