摘要

姿態控制主要是靠前庭脊髓反射作用，使用固定之測力板，可收集受測者之重心移動資料，間接反應出前庭脊髓反射作用，以達到姿勢描計檢查之效果，但各文獻所用的比較參數和測試時間長短不同。本研究共有54名正常人接受不同時間之測力板檢查，以比較靜態姿勢描計檢查中，各參數之重覆性和變異性，以及何種測試時間比較適合臨床上使用。統計結果顯示，重心移動軌跡此一參數，不管是在同一受測者，或不同受測者間之可信度最大；而60秒內之測試時間比30秒更適合臨床上使用。

Human upright postural control mainly relies upon the descending vestibulospinal reflex (VSR). Romberg test was the first one used to evaluate the function of VSR, and then electromyography and sway magnetometry followed. Recently, computerized force platform was used to collect and calculate the data of change of center of pressure (COP) which reflects postural control. The goal of this study was to investigate the clinical significance of applying fixed force platform in evaluating postural control of normal subjects.
Results showed the parameter of sway length is more reliable than that of sway area, and the 60s’ teat duration is more suitable in clinical evaluation. We conclude that static posturography using fixed force platform is a sensitive, rapid, quantitative, not harmful and reliable test that can be used as a screening and monitoring tool in otoneurology.
