Abstract
Description
本發明是有關於一種復健監控技術,且特別是有關於一種應用於巴金森氏病(Parkinson’s disease)的復健監控系統及其方法。The invention relates to a rehabilitation monitoring technology, and in particular to a rehabilitation monitoring system and method applied to Parkinson's disease.
巴金森氏病是一種慢性中樞神經系統退化性疾病,全球約有八百萬人罹患此疾病,其主要的症狀包括震顫、肢體僵硬、運動功能退化、步態異常及講話音量變小等。而目前針對巴金森氏病的醫療處置,除了藥物、外科治療、理療之外,運動復健亦能有助於病患恢復並增強肌力、關節靈活度、功能技巧及耐力。例如, Lee Silverman Voice Treatment Big (LSVT BIG)是醫師優先選擇的復健運動之一。Parkinson's disease is a chronic degenerative disease of the central nervous system. About 8 million people worldwide suffer from this disease. Its main symptoms include tremor, stiff limbs, deterioration of motor function, abnormal gait, and reduced speech volume. At present, in addition to drugs, surgical treatment and physical therapy, sports rehabilitation can also help patients recover and enhance muscle strength, joint flexibility, functional skills and endurance. For example, Lee Silverman Voice Treatment Big (LSVT BIG) is one of the preferred rehabilitation exercises for physicians.
LOUD BIG有助於改善巴金森氏病患者特有的動作緩慢、肢體僵硬、細碎動作、起始障礙等問題,針對軀幹旋轉幅度、平衡能力、步態穩定性、運動執行速度等執行訓練進而提升生活品質。此復健方法經研究中證實,若每周進行4次且每次1小時,共計16小時的一個月密集訓練後,其治療成效能夠維持6個月。LOUD BIG helps to improve the unique slow movements, stiff limbs, fine movements, and initial obstacles of patients with Parkinson's disease. It executes training on trunk rotation, balance ability, gait stability, and exercise execution speed to improve life quality. This rehabilitation method has been confirmed by research. If 4 times a week and 1 hour each time, a total of 16 hours of intensive training for a month, the therapeutic effect can be maintained for 6 months.
目前巴金森氏病之運動復健治療的成效是基於醫師每一個月共16次的評估,醫師會結合多項指標進行綜合評分。然而,這些評估結果都是醫師主觀判別,兩名醫師可能會有不同的結果。此外,目前評估的評分階層過於簡化。雖然過往已有各種針對運動障礙或特殊病症進行量測與記錄的實驗,但多數只能在臨床或實驗室中進行。儘管復健情況能透過模擬來評估,但這樣的評估結果並無法真實代表病人的家庭生活環境。由此可知,現有技術針對復健情況的評估,對於復健治療最終目的及提升病患生活品質,皆未能帶來足夠的正面影響。At present, the effectiveness of sports rehabilitation treatment for Parkinson's disease is based on a total of 16 evaluations by physicians every month, and physicians will combine multiple indicators for comprehensive scoring. However, these evaluation results are subjective judgments by physicians, and the two physicians may have different results. In addition, the scoring hierarchy currently evaluated is too simplified. Although there have been various experiments for measuring and recording dyskinesia or special conditions in the past, most of them can only be performed in clinical or laboratory. Although the rehabilitation situation can be evaluated through simulation, the results of such an assessment cannot truly represent the family living environment of the patient. It can be seen that the assessment of the rehabilitation situation in the prior art has not brought enough positive impact on the ultimate goal of rehabilitation treatment and improving the quality of life of patients.
臨床上醫師針對復健療程有三大困擾問題:(1)患者回家後是否有依照療程進行復健?(2)每次復健多久?(3)復健過程如何追蹤與分析?有鑑於此,本發明提供一種應用於巴金森氏病的復健監控系統及其方法,其可即時判斷患者的復健運動是否標準,其感測數據亦可供醫師診斷參考,使復健運動能更有效地改善病況。Clinical physicians have three major problems in the rehabilitation process: (1) Does the patient return to the treatment process after returning home? (2) How long does each rehabilitation take? (3) How to track and analyze the rehabilitation process? In view of this, the present invention provides a rehabilitation monitoring system and method applied to Parkinson's disease, which can immediately determine whether the patient's rehabilitation exercise is standard, and its sensing data can also be used by the physician for diagnostic reference to make the rehabilitation exercise Can improve the condition more effectively.
本發明應用於巴金森氏病的復健監控系統,其包括穿戴裝置及運算裝置。穿戴裝置包括數個感測器,這些感測器用以感測使用者不同身體部位的動作姿態。而運算裝置則依據這些感測器的動作姿態,評估使用者的復健運動與至少一標準動作的差異。此復健運動是關於巴金森氏病。The invention is applied to a rehabilitation monitoring system for Parkinson's disease, which includes a wearing device and a computing device. The wearable device includes several sensors, and these sensors are used to sense the movement postures of different body parts of the user. The computing device evaluates the difference between the user's rehabilitation movement and at least one standard movement based on the movement posture of these sensors. This rehabilitation exercise is about Parkinson's disease.
另一方面,本發明應用於巴金森氏病的復健監控方法,其包括下列步驟。感測使用者不同身體部位的動作姿態。依據這些感測器的動作姿態,評估此使用者的復健運動與標準動作的差異。而此復健運動是關於巴金森氏病。On the other hand, the present invention is applied to a rehabilitation monitoring method for Parkinson's disease, which includes the following steps. Sensing the movement posture of different body parts of the user. Based on the movement posture of these sensors, the difference between the user's rehabilitation exercise and the standard movement is evaluated. And this rehabilitation exercise is about Parkinson's disease.
基於上述,在本發明實施例應用於巴金森氏病的復健監控系統及其方法中,提供穿戴裝置讓使用者穿戴。而穿戴裝置上的感測器可偵測加速度、角速度、磁力等運動狀態,且其設置位置對應到使用者的關節或其他身體部位,從而得出使用者的動作姿態。接著,感測的動作姿態可用於判斷使用者的動作是否符合標準動作,讓使用者能以正確動作進行復健運動,且取得的資訊可供醫師遠端追縱復健狀態。Based on the above, in the rehabilitation monitoring system and method for Parkinson's disease according to the embodiments of the present invention, a wearable device is provided for the user to wear. The sensor on the wearable device can detect motion states such as acceleration, angular velocity, and magnetic force, and its setting position corresponds to the user's joints or other body parts, thereby obtaining the user's motion posture. Then, the sensed motion posture can be used to determine whether the user's motion conforms to the standard motion, so that the user can perform the rehabilitation exercise with the correct motion, and the obtained information can be used by the physician to track the rehabilitation state remotely.
為讓本發明的上述特徵和優點能更明顯易懂,下文特舉實施例,並配合所附圖式作詳細說明如下。In order to make the above-mentioned features and advantages of the present invention more obvious and understandable, the embodiments are specifically described below in conjunction with the accompanying drawings for detailed description as follows.
圖1是依據本發明一實施例之復健監控系統1的示意圖。請參照圖1,復健監控系統1至少包括但不僅限於穿戴裝置10、 運算裝置30及顯示裝置40。FIG. 1 is a schematic diagram of a
穿戴裝置10可供使用者的上半身、下半身、四肢或任何身體部位穿著,其主體可能是上衣、褲子、外套等形式。於本實施例中,穿戴裝置至少裝設有但不僅限於一個或更多個感測器110及通訊傳輸器130。The
感測器110可以是加速度計(accelerometer)、陀螺儀(gyroscope)、磁力計(magnetometer)、或前述組合的三軸以上感測模組,並用以感測加速度、角速度、磁力等感測數據,從而得出設置位置的運動狀態,進而得出使用者的動作姿態。值得注意的是,複數個感測器110分別設置於穿戴裝置10主體上。而使用者穿上此穿戴裝置10之後,這些感測器110例如會對應到使用者的雙手前臂、雙手上臂、脊椎、雙腳大腿、雙腳小腿等身體部位,並可對應到四肢、頸部及/或背部的關節。需說明的是,感測器110的數量及位置可依據需求而調整,而其設置位置若能有效代表使用者運動狀態(例如,雙手外展、單腳前彎、胸腰屈曲等)者則為較佳設置位置。The
此外,這些感測器110可能分別連接有微控制器,微控制器會基於感測器110所取得的加速度訊號、角速度訊號和磁力計訊號,使用方向餘弦矩陣(Direction Cosine Matrix,DCM)、或Madgwick等演算法來計算出姿態歐拉角(傾仰(pitch)、側偏(roll)、偏航(yaw)),以作為對應身體部位的動作姿態(例如,肩與肘、髖關節等角度值)。而在一些實施例中,感測器110可能內建有基本控制器以直接得出動作姿態。In addition, these
通訊傳輸器130可以是藍牙、Wi-Fi、紅外線等無線通訊發射器、或是通用串列匯流排(Universal Serial Bus,USB)、雷電(Thunderbolt)、通用異步收發傳輸器(Universal Asynchronous Receiver/Transmitter,UART)等有線傳輸介面,並用以將不同身體部位的動作姿態相關數據發送到外界(即,外部裝置)。The
運算裝置30可以是桌上型電腦、筆記型電腦、智慧型手機、平板電腦等電子裝置,其至少具有處理器、與通訊傳輸器130對應的接收器、及記憶體,以取得來自穿戴裝置10的動作姿態相關數據,並據以對動作姿態進行分析及評估,其詳細內容待後續實施例說明。The
顯示裝置40與運算裝置30連接,並可以是液晶顯示器(Liquid Crystal Display,LCD)、發光二極體(Light Emitting Diode,LED)顯示器或有機發光二極體(Organic Light Emitting Diode, OLED)顯示器等各類型顯示器。運算裝置30可控制顯示裝置40呈現畫面,其詳細內容待後續實施例說明。The
為了方便理解本發明實施例的操作流程,以下將舉諸多實施例詳細說明本發明實施例中針對巴金森氏病復健運動的監控流程。下文中,將搭配復健監控系統1中的各項裝置、元件及模組說明本發明實施例所述之方法。本方法的各個流程可依照實施情形而隨之調整,且並不僅限於此。In order to facilitate understanding of the operation process of the embodiment of the present invention, a number of embodiments will be described in detail below to describe the monitoring process for the rehabilitation exercise of Parkinson's disease in the embodiment of the present invention. Hereinafter, the methods described in the embodiments of the present invention will be described with various devices, components, and modules in the
圖2是依據本發明一實施例之復健監控方法的流程圖。請參照圖2,感測器110會感測使用者不同身體部位的動作姿態(步驟S210)。於本實施例中,不同感測器110裝設在穿戴裝置10主體上對應於使用者不同身體部位,可即時取得加速度、角速度、磁力等運動或物理狀態,並透過諸如DCM演算法得出動作姿態相關數據(例如,歐拉角),這些數據即可作為各身體部位的動作姿態的代表數據。2 is a flowchart of a rehabilitation monitoring method according to an embodiment of the invention. Please refer to FIG. 2, the
接著,通訊傳輸器130將動作姿態相關數據傳送至運算裝置30。運算裝置30即可依據感測器110所感測的動作姿態,評估使用者執行復健運動與標準動作的差異(步驟S230)。具體而言,以LSVT BIG巴金森氏病復健運動為例,其包括七項運動(例如,地板至天花板(Floor to Ceiling)、前跨及到達(Forward Step and Reach)、後跨及到達(Backward Step and Reach)等),且各復健運動又包括不同動作(例如,坐後跨步、右前跨步等)。而病患對於這些動作的達成率是用於評估復健歷程的重要數據。Next, the
為了協助病患清楚得知自己的動作是否符合復健運動的標準動作,本發明實施例可提供介面來模擬人體姿態。運算裝置30可基於二維或三維圖像的渲染引擎、電腦動畫、遊戲引擎(例如,Unity、Havok、Chrome Engine等)等系統來模擬使用者的人物模型(步驟S231)。此人物模型是預先設定好的二維或三維人形物件。例如,圖3是一實施例說明三維之人物模型HM的示意圖。請參照圖3,人物模型HM的各指示點IL是分別對應到穿戴裝置10的各個感測器110。此外,這些指示點IL是用來描述解剖平面及運動角度的關節或輔助參考點。In order to assist the patient to clearly know whether his movement conforms to the standard movement of rehabilitation exercise, the embodiment of the present invention may provide an interface to simulate the posture of the human body. The
運算裝置30可透過顯示裝置40呈現人物模型HM依據那些感測器的動作姿態同步進行運動的畫面(步驟S233)。運算裝置30首先可對人物模型HM進行校正。例如,患者保持以下固定姿勢:雙腳併攏、雙手自然垂放、軀幹挺直(即,立正姿勢),5秒後完成校正。而在Unity環境中,以子物件進行肢體正規化,並以父物件接收感測器110的讀值,即可進行肢體動作模擬。完成校正後,子物件將隨父物件同步旋轉運動,且使用者可開始進行復健運動。The
而在復健運動的過程中,運動裝置30可對運動能力進行評估。運算裝置30可依據動作姿態的相關數據來計算出特定運動特徵角度。具體而言,圖4是一實施例說明對人物模型HM上向量定義的示意圖。請參照圖4,這些向量
~
可代表使用者的肢體及軀幹。而二維或三維空間中兩向量之間的夾角可基於向量內積公式得出。不同夾角可作為評估動作姿態的特徵角度θ。例如,左肩外展、右肩外展、胸腰屈曲伸直、胸腰旋轉、左肩屈曲伸直、右肩屈曲伸直、左肘屈曲伸直、右肘屈曲伸直、左髖外展、右髖外展、左髖屈曲伸直、右髖屈曲伸直、左膝屈曲、右膝屈曲、左髖外轉、右髖外轉、水平左肩外展、水平右肩外展等特徵角度。
During the rehabilitation exercise, the
而運算裝置30記錄有不同復健運動中各標準動作進行下不同身體部位的對應空間位置及特徵角度,運算裝置30即可比對感測器110所偵測數據對應空間位置及/或特徵角度與標準動作對應空間位置及/或特徵角度之間的差異(例如,距離差、夾角等),從而評估使用者所進行的復健運動與標準動作之間的差異。The
在一實施例中,運算裝置30可依據此差異而透過顯示裝置40呈現人物模型HM上對應身體部位是否符合標準動作的畫面(步驟S235)。以圖3為例,當感測器110偵測數據對應的空間位置與標準動作之間的差異小於第一門檻時,表示使用者當前的動作姿態的達成度超過百分之七十五;而若差異介於第一及第二門檻值之間,則表示當前動作姿態的達成度為百分之五十到七十五之間;而若差異大於第二門檻值,則表示達成度不到百分之五十。人物模型HM上的對應指示點IL即作為警示燈,而運算裝置30則依據各關節部位的動作姿態與標準動作之間的差異來控制警示燈的變化。例如,運算裝置30可基於前述達成度而透過在人物模型HM上的對應指示點IL(即,關節部位)呈現諸如綠(表示達成率超過百分之七十五)、黃(表示達成度為百分之五十到七十五之間)、紅(表示不到百分之五十)等不同視覺表現形式,以協助使用者了解自己的身體部位是否符合標準動作或達成度。In an embodiment, the
需說明的是,圖3所示僅是用於呈現與標準動作之差異的範例,於其他實施例中,運算裝置30可透過顯示裝置30透過文字(例如,左肩向前、右肘向外等)、圖形(例如,正確圖形、數據曲線圖、數據樹狀圖等)等形式來呈現,亦可能透過揚聲器(即,喇叭)來播放動作修正提示訊息。標準動作的各項數值可事先設定並可事後調整。It should be noted that FIG. 3 is only an example for showing the difference from the standard action. In other embodiments, the
此外,復健運動中的各動作的進行流程包括開始、執行、及結束。而不同動作與訊號判定範圍可能不同,例如,前跨(step forward)動作判定的標準為肩外展的特徵角度需大於30度,且直到此角度小於30度時才判定動作結束。而為了比較與分析,運算裝置30可去除各特徵角度對應訊號的前後特定百分比(例如,百分之十、二十五、四十五等),藉以比較不同取樣範圍對於姿勢判讀所造成影響。In addition, the flow of each action in the rehabilitation exercise includes start, execution, and end. Different actions and signal determination ranges may be different. For example, the criterion for step forward action determination is that the characteristic angle of shoulder abduction needs to be greater than 30 degrees, and the action is not determined until this angle is less than 30 degrees. For comparison and analysis, the
而為了輔助病患進行復健運動時採用正確的動作或解決病患忘記動作的問題,運算裝置30還能透過顯示裝置40呈現標準動作的引導影片(對人員以標準動作進行復健運動時進行影像錄製所得)。舉例而言,圖5是一實施例說明引導影片及人物模型的示意圖。請參照圖5,顯示裝置40呈現的畫面可結合引導影片GV與對應於感測器110所得感測數據的人物模型HM,人物模型HM以鏡像方式呈現。例如,病患踏出左腳,則人物模型HM亦同步踏出左腳。藉此,病患可清楚得出復健運動的內容,也可即時得知自身動作與標準動作的差異。In order to assist the patient in adopting correct movements during the rehabilitation exercise or to solve the problem of the patient forgetting the movement, the
為了避免多人復健情況下顯示裝置40的畫面過於混亂並影響視覺感受,請參照圖6是一實施例說明引導影片及複數人物模型的示意圖。在多人復健情況下,顯示裝置40僅需要播放單一引導影片GV,而不同病患對應的人物模型HM則分配在畫面中不同區域。需說明的是,前述實施例是以影片來引導動作,然在一些實施例中,運算裝置30亦可透過揚聲器來播放關於復健運動的動作指示。In order to avoid that the screen of the
感測器110所得動作姿態的相關數據除了可即時反應病患的姿勢是否正確,這些數據還能進一步上傳或發送到醫師的電腦裝置(以運算裝置30為例,也可能是其他運算裝置)。運算裝置30可統計病患多次進行相同動作下的各特徵角度變化,並可與標準動作對應特徵角度比較,從而協助醫師判斷病患進行復健運動的進步或退步幅度。In addition to the data related to the motion posture obtained by the
例如,表(1)是一範例說明左右肩外展的特徵角度量測值。假設標準動作對應特徵角度為七十度,則左肩外展由59.01度至66.70度,故有百分之十三左右的進步幅度;而右肩外展由72.86度至71.44度,故有百分之二左右的退步幅度。而七次重複動作的平均值及最大值亦可與標準動作對應特徵角度比較,以作為達成率的判斷參考。 表(1)
除此之外,運算裝置30還能取得歷史復健資料,此歷史復健資料是關於某一使用者先前進行復健運動所偵測到的動作姿態(例如,三天前、一個月前動作姿態相關數據)。而運算裝置30可比對當前感測的動作姿態與歷史復健資料,以得出復健前後比對結果。除此之外,運算裝置30還能紀錄病患每次執行復健運動的時間長度,以作為復健運動完成度的評估。In addition, the
綜上所述,本發明實施例應用於巴金森氏病的復健監控系統及其方法,提供互動式介面,讓病患穿上裝設有感測器的穿戴裝置後,能透過介面模擬病患的動作,使病患能及時了解動作是否正確或與標準動作的達成率。介面上還能呈現引導影片,讓病患了解當前執行的動作。此外,關於動作姿態的相關數據經統計後能幫助醫師遠端診斷病患進行復健運動的達成率及狀況。In summary, the embodiments of the present invention are applied to a rehabilitation monitoring system and method for Parkinson's disease, which provides an interactive interface so that patients can simulate a disease through the interface after wearing a wearable device equipped with a sensor The patient’s movements enable the patient to know in time whether the movements are correct or the achievement rate with the standard movements. The interface can also present guide videos to let patients understand the current actions performed. In addition, the statistics on the movement posture can help the doctor to diagnose the patient's achievement rate and status of rehabilitation exercise remotely after statistics.
