我们研究了男性成年舞者和未经训练的受试者对视觉、姿势控制和感知的依赖程度。首先，在自由跷跷板平台上分析了人体摇摆。快速傅立叶变换处理允许对加速度计记录的平台摆动进行频谱频率分析。其次，采用视觉依赖测试，棒框测试（RFT）。与未经训练的对象相比，专业舞者明显更稳定，对姿势控制和感知的依赖程度也更低。据推测，专业舞蹈训练加强了本体感受输入的准确性，并将感觉运动优势从视觉转移到本体感受。对于舞者而言，RFT视觉依赖与姿态视觉控制之间存在交互作用：对RFT的视觉依赖越少，他们在动态平衡条件下越稳定。1999爱思唯尔科学爱尔兰有限公司版权所有。
We studied the degree of dependence on vision, for postural control and for perception, among male adult dancers and untrained subjects. First, body sways were analyzed on a free seesaw platform. Fast Fourier transform processing allowed spectral frequency analysis of the platform sways recorded by an accelerometer. Secondly, a visual dependence test, the rod and frame test (RFT) was used. Professional dancers were significantly more stable and less dependent on vision for postural control and for perception than untrained subjects. Presumably, professional dance training strengthens the accuracy of proprioceptive inputs and shifts sensorimotor dominance from vision to proprioception. For the dancers, there was interaction between the RFT visual dependence and the visual control of posture: the less visual-dependent they were for the RFT, the more stable they were in dynamic balance conditions.
