振动觉振动物体接触身体时产生的感觉。通常认为它是触觉的一种，是反复激活触压觉而产生的。临床发现，脊髓痨患者的振动觉发生障碍后，触觉仍然保留，而且会变得更敏感，所以，也有人认为振动觉是不同于触觉的一种独立的感觉。一般认为巴西尼小体是振动感受器。振动感受性有一定的频率极限。振动刺激低于或高于一定频率，将不引起振动觉，其下限为10～18赫，上限在650～8000赫之间。振动觉的强度绝对阈限依赖于振动频率，也随刺激器接触皮肤的面积大小及身体部位而不同。这种阈限值是以皮肤位移幅度的分贝数来表示的，一般以1微米为参照。根据现有的材料,在10～1000赫的频率范围内,多数频率的绝对阈限值在5分贝和－20分贝之间,但也有高达30分贝以上或低至-30分贝以下的,在上述频率范围内,绝对阈限曲线呈U形:在40～50赫时,阈限比较高，然后随着频率增高而逐渐降低,到250赫左右到达最低点,此后阈限又随频率的增高而上升。无毛发皮肤的阈限值在不同频率上均低于有毛发皮肤。因此，有人将这个绝对阈限曲线分为低频段和高频段。并推想可能存在着低频和高频两振动感受器。振动感受性具有空间和时间总合的效应。如果振动刺激作用于皮肤的面积增大，强度绝对阈限将下降，出现空间总合。同时刺激两个邻近的皮肤点或身体的两个对称部位，也会出现空间总合。在一定范围内，随着振动刺激的作用时间增加，强度绝对阈限下降，出现时间总合。但振动刺激的长期作用可导致适应，使振动感受性降低。与触觉适应相比，振动觉的适应过程较慢。
