摘要

對於半身偏癱（hemiplegia）的病人，站立對稱平衡（postural symmetry）和步長及偏癱的嚴重度有極大的相關性。傳統站立平衡訓練儀為腦傷病患如腦血管病變以及頭部外傷病患等患者在復健治療中極為重要且常用的一項訓練工具。其主要功能係在於訓練病患重建其站立靜態和動態平衡功能，以奠定日後學習步行及自立生活的能力。
在本研究中，設計製作一部其生物回饋的站立平衡訓練儀，這部儀器是以傳統站平衡訓練桌加上回饋系統 （biofeedback）而成。兩腳底板均各有一踩重的儀器式感應計測器及一組可及時顯示之視覺／聽覺回饋顯示器。並且將急性中風後及頸部外傷病患六十名隨機分成控制組及實驗組，經過四星期的訓練後，實驗組及控制組之姿勢對稱百分比由15.6±10.5%及16.8±10.3%降至3.5±2.2%及10.1±6.4% （p=0.002）。左側及右側偏癱均無差異，結果頤示這部新型迴饋站立平衡訓練儀對中風患者在站立對稱有較好的訓練療效。

For the patient with neurological damage of central nervous system, such as CVA or head injury, standing balance training is very important before walking and self-care training. Stance symmetry in hemiplegic patients had been reported to be significantly related to measurement of severity and length of stay.
The present equipment for standing balance training in occupational therapy is too simple in design and with limited function, lack of self-feedback system, unable to adjust the slope of the training table. A newly standing biofeedback training device including instrumented sensors of weight bearing under dual force plat-form and a real time visual/auditory feedback system had been developed for postural training.
Sixty patients with hemiplegia after acute stroke or traumatic brain injury were randomly divided into an experimental and a control groups. They were either trained by the new designed standing balance equipment or the conventional equipment for 5 times per week, 20 minutes at each section. After training for a period of four weeks, the percentage of postural symmetry in experimental and control groups were reduce from 15.6±10.5 % and 16.8±10.3 % to 3.5±2.2% and 10.1±6.4 % respectively (p=0.002). There was no significant difference between right and left hemiplegia patients. The results indicated that this newly designed standing biofeedback device had good training effect on stance symmetry in hemiplegic patients.
