姿势描记法（Ｐｏｓｔｕｒｏｇｒａｐｈｙ，ＰＳＧ）对定量分析眩晕患者是否存在单侧或双侧迷路病变具有参考价值。我们使用自行研制的Ｗ－Ⅰ型前庭－脊髓反射功能测量系统对４８４例主诉眩晕患者进行了测试。对其中临床诊断明确的２０４例患者ＰＳＧ进行了统计分析，提出了ＰＳＧ分类标准。根据重心集中点是否存在，ＰＳＧ可分为四种类型；再依据重心移动方向分为四种方向形式，共１６种ＰＳＧ图形类别。其中三种左右型和三种前后型ＰＳＧ对判定患者是否存在单侧或双侧迷路病变的符合率分别为８４．８％和７７．８％。并对上述图形产生机理进行了讨论。
Posturography (PSG) is useful for quantitative analysis of vertigo patients with unilateral or bilateral labyrinthine lesions. We used a self-developed W-Ⅰ vestibular-spinal reflex functional measurement system of 484 patients complained of vertigo. The PSG of 204 patients with definite clinical diagnosis were statistically analyzed, and the PSG classification standard was proposed. According to the existence of center of gravity, PSG can be divided into four types; then according to the direction of movement of the center of gravity is divided into four directions, a total of 16 kinds of PSG graphics categories. The coincidence rates of three kinds of left and right type and three kinds of anterior and posterior type of PSG for determining the presence or absence of unilateral or bilateral labyrinthine lesions were 84.8% and 77.8% respectively. The mechanism of the above graph generation is also discussed.
