Previous studies have investigated the relationship between muscular tension, body posture, and voice quality. The aim of this paper is to study the postural pattern during voice production in healthy subjects compared with patients affected by voice disorders and in the same patients before and after vocal treatment by means of static posturography. Classic posturographic variables and spectral frequency analysis of body sway have been measured. Posturographic values in patients before vocal treatment and controls were within normal ranges but not homogeneous. Body sway significantly decreased during voice production in patients after voice training. Spectral frequency analysis of body sway showed a significantly decreased body sway at middle frequencies on the anteroposterior (y) plane during voice production after voice training. Our results would suggest that in patients affected by voice disorders rehabilitative treatment may cause an improvement of the body proprioceptive scheme and this improvement might be useful to evaluate the proper (ongoing) treatment.
先前的研究调查了肌肉张力、身体姿势和嗓音质量之间的关系。本文旨在通过静态姿势描记法，研究健康受试者在发声过程中的姿势模式，并与嗓音障碍患者以及同一批患者在嗓音治疗前后的情况进行比较。已测量了经典的姿势描记变量和身体摆动的频谱分析。嗓音治疗前患者和对照组的姿势描记值在正常范围内，但不均匀。嗓音训练后患者在发声过程中身体摆动明显减少。身体摆动的频谱分析显示，嗓音训练后发声过程中，在前后（y）平面的中频处身体摆动明显减少。我们的结果表明，对于嗓音障碍患者，康复治疗可能会改善身体本体感觉模式，这种改善可能有助于评估适当的（正在进行的）治疗。
