84碩士論文:動態站姿平衡度定量評估之研究

  腦血管病變及意外腦傷病患近年來持續高踞國內十大死亡原因之第二位,由於腦神經組織損傷,在病發後會造成患側肌力(muscle power)下降、肌肉痙攣性(spasticity)增強、運動失調(ataxia)以及運動控制功能受到干擾,以致平衡能力發生障礙,當其跨步行走時,常因重心控制不當而跌倒。因此,平衡控制訓練便成為臨床上重建病患運動控制能力、學習步行及培養自理生活能力重要的復健訓練項目之一。本研究的第一部份,對正常人和中風偏癱病患進行動態站立平衡實驗,收集病患在平衡反應時腳壓中心晃動軌跡進行分析、驗証,以期了解人體站立平衡控制之機制,並進而改 良站立平衡復健設備功能及發展臨床上評估病患跌倒危險指標之基礎資料。第二部份之研究重點,便是依照臨床需要設計、開發一台兼具病患轉身平衡能力評估及訓練功能之復健設備。本項設備在臨床上除可提供醫療人員對偏癱病患進行動態轉身平衡之評估與訓練,做為定量、客觀評估療效之依據外;在應用方面,研發試製之產品雛型也將具有申請專利之潛力,所發展之系統設計理念、軟硬體更可移轉至關產業,藉此喚起國人自製研發本土化復健醫療器材之興趣,促進國內醫療產業之升級。

Quantitative Study of Dynamic Postural Stability for Stroke Patients

Postural control is the ability to maintain the body’s center-of-gravity over the base of support during upright standing. It is a complex process involving the coordinated actions of biomechamical, sensory, motor and central nervous system components. However, postural control like vision and hearing functions of human body will deteriorated over years. In U.S.A., about 30 percent of people older than 65 years of age experience a fall with approximately half of them havi?OMultiple incidents due to impairmt of postural control functions.
In addition, people who are at fall risk particularly if they had several injurious falls, tend to develop a fear of falling, which restricts their activities. Consequently, they develop lower extremity dysfunction in the form of disuse atrophy.In Taiwan, CVA has been ranking as the second column in the leading cause of death in the past ten years. The brain tissue injured after CVA can cause various complications such as decreased muscle power, increase spastic of the affected side, motor control disturbance and ataxia. As a result, balance control are affected and fall accident is noted frequently during ambulation.
Therefore, more effective dynamic postural control stability training protocols and modalities are needed for the patients with neulogical motor disabilities to regain their postural control function.Based on the abovementioned motivation, this research will focus on two issues in the area of postural control. In the first part of this research, an quantitative assessment model to evaluation standing postural stability will be established. The clinical experimental data (i.e. joint displacements, COP sway patterns) during upright standing balance tests for 11 stroke patients and 12 normal subjects will be analyzed.
 The postural recovery responses in turn of COP sway distance and latency of postural respse unites A/P and M/L directional disturbances will be compared between two test groups. A two dimen
