中風偏癱患者伸手及物功能評估系統之研發

Abstract

中風是導致成人失去能力的主要原因之一，其中以上肢動作的問題最為常見，約有三分之二的中風患者因為患側上肢無法進行功能動作而失去活動的獨立性。中風病人上肢動作功能的恢復往往留下功能缺失，而影響日常生活功能的表現。因此發展出一套有效的臨床評估中風病人上肢動作功能的方法，將有助於減少中風病人上肢動作功能的殘留缺失及提增日常生活功能的表現，近而促進中風病人的生活品質。 臨床上物理治療師評估中風患者上肢功能往往只能依賴一些量表進行評估，而可以提供客觀的上肢運動學參數之動作分析系統又十分昂貴且不易操作。綜上所述，本研究提供一個操作方便、成本低廉的簡易上肢功能評估之系統。此系統以LabVIEW做為核心，利用加速規和電子尺等感測器的特性，搭配電腦上虛擬實境的人機介面，將中風偏癱患者的伸手動作分析後取得量化參數的結果，最後再交由臨床治療師做為參考的依據。藉由量測不同的中風偏癱患者，比較其運動學特徵與上肢功能的關係，以運動學的特徵評估上肢功能，達到簡易上肢功能評估的目的。

Stroke is one of the major causes of adult disabilities, among which upper motion problems are the most commonly seen. About two-third of stroke patients are unable to use their upper limb functionally and lost their independence of activities of daily living. Stroke patients often remain affected upper limb motor impairment and demonstrate disability in performing activities of daily living. Due to the growth of neuroscience, the relationships between brain reorganization and therapy-induced motor recovery have been further explored. Thus, the development of clinical evaluation based on neuroscience evidence, for the interventions of paretic upper motor recovery will contribute to the recovery of motor function, and consequently increase the quality of life for patients with stroke. Only some clinical evaluation instruments were available to evaluate the upper extremity functions of stroke for a physical therapist. Motion analysis systems could provide objective kinematic data of stroke patients. according as mention above, in this study we designed an upper limbs function system that has a reasonable price and easy to use. Using the LabVIEW, accelerometers and potentiometers collected the parameters of reaching movement for hemiplegic patient. These parameters then transferred to the clinical therapist as the basis that consulted afterwards. We measured the reaching movement analysis, compared the kinematics characteristic with upper limb function for the different hemiplegic patient, can assess the upper limbs function with the characteristic of kinematics and achieve the purpose of the easily upper limbs function.
