視覺化IMU-跑步機輔具設計及其在中風患者步態訓練之應用

Abstract

近年來由於醫學的長足進步，使得腦中風死亡率逐年下降。但同時，人口老化的問題卻也使得腦中風的患者日益增加。在中風治療的過程中，中風患者的復健治療是最重要的環節之一。中風後的復健中，步態的恢復一直被認定為最主要的治癒目標，在現今醫院的復健科與復健診所裡，跑步機訓練是最常見的步態治療方式。當患者進行跑步機訓練時，除非有復健師在旁修正患者的步態狀況，不然患者無法得知自己的步態情形。因此本論文提出了新的步態訓練方法，利用IMU量測患者髖關節與膝關節的角度變化，並以視覺回饋的方式讓患者得知目前步態訓練的狀況，加以改善。本方法不僅能減少復健人力的負擔還可增加復健評估的資料。為了驗證IMU-跑步機訓練的效果，本論文收取20位中風患者，且將這20位中風患者隨機分配至實驗組與控制組，實驗組接受『IMU-跑步機訓練』，而控制組接受『傳統跑步機訓練』，經由實際臨床實驗驗證後，本論文所提出的步態訓練方法比傳統跑步機訓練更能提升步態復健效率。

As a result of medical advances in recent years, stroke mortality rates have been decreasing. Nevertheless, there has been a gradual increase in the number of stroke patients due to the problems of population aging. During the process of stroke therapy, rehabilitation is one of the most essential parts for stroke patients, and recovery of gait has always been considered the main goal of stroke treatment. In both the Divisions of Rehabilitation and rehabilitation clinics, treadmill training is the most common gait therapy. When a patient is put on a treadmill for training, nonetheless, he would not know how he walks unless a physical therapist helps correct his gait by his side. Therefore, this essay proposes a new method of gait training. It begins with measurement of angle changes in patient’s hip and knee joints by utilizing IMU. Moreover, it helps the patient understand his physical status as he is given visual feedback, and he may thus help himself to correct his error. This method may not only mitigate the burden of human resource, but it may also provide additional data for rehabilitation assessment. To prove the effect of IMU-treadmill training in stroke patients, twenty subjects with stroke were included in the study. They were randomly assigned to either the experimental group or the control group. Subjects in the experimental group received “IMU-treadmill training,” while those in the control group were given “traditional treadmill training.” After completing the clinical trial, it is proven that the “IMU-treadmill training” is more effective than the “traditional treadmill training” for stroke patients.
