下肢站立時動態平衡能力訓練與評估系統Dynamic balance ability training and evaluation system for lower limbs standing

本發明係關於一種下肢站立時動態平衡能力訓練與評估系統，尤指一種使用預期性訓練來篩檢老人是否有跌倒危險之下肢站立時動態平衡能力訓練與評估系統。The invention relates to a system for training and evaluating the dynamic balance ability of a lower limb when standing, in particular to a training and evaluation system for using the expected training to screen the elderly for the risk of falling and the dynamic balance ability of the lower limb standing.

高齢社會(Aged Society)中跌倒是威脅老年人健康品質的最大危險因子之一，研究及早篩檢出有潛在跌倒的高危險群老人及研發出預防老人跌倒的平衡復健設備，將有助於減低老人跌倒的發生率。Falling in the Aged Society is one of the biggest risk factors threatening the health quality of the elderly. Studying early screening of high-risk groups of people with potential falls and developing balanced rehabilitation equipment to prevent falls in the elderly will help Reduce the incidence of falls in the elderly.

臨床上常用平衡量表或功能性之測試來代表病患之平衡能力，常見的有伯格氏平衡量表(Berg Balance Scale)及起立行走計時測試(Timed “Up ＆ Go” Test)等。伯格氏平衡量表(Berg Balance Scale)-伯格氏平衡量表最早由Berg等學者於1989年設計於臨床上用來評估社區老年人之功能性站立平衡，於1992年及1995年則陸續被使用於老年人及急性期中風病患，研究結果顯示此一平衡量表有極佳之測試者內(Within-Rater)及測試者間(Between-Rater)信度(ICC皆為0.98)，且具極佳之內在一致性表現(Cronbach’s α=0.96)；1996年Bogle等學者利用此一平衡量表之分數來預測老年人跌倒之機率，結果發現當得分於45分以下者相較於得分45分以上者有較高之跌倒機率，雖不能以此量表預測是否得分數愈低有愈高跌倒之機率，但在臨床上卻提供一分數之切點(Cut Off Score)來預測跌倒之可能性。起立行走計時測試(Timed “Up ＆ Go” Test)-起立行走測試(“Get-up and Go” Test)最早於1986年Mathias等學者研究40位有平衡功能障礙之老年人，利用攝影之方式觀察其由一有把手之坐椅站起並行走於三公尺之步道後轉身走回再執行坐下之動作，此一測試結合由坐到站、步行、轉身及站到坐等日常功能活動，雖然研究結果顯示此為一快速且實用之平衡功能測試，但關於其評分標準卻太過於簡略為其缺點，只依照觀察者主觀地評分將動作執行情況分為1至5分五種等級，對於評分結果只有極端值1分及5分有較一致的共識，但針對中間分數2至4分之定義則較不客觀。Clinically, a balance scale or functional test is used to represent the patient's balance ability. Commonly, the Berg Balance Scale and the Timed “Up & Go” Test are used. The Berg Balance Scale-Berg Balance Scale was first designed by Berg et al in 1989 to evaluate the functional standing balance of the elderly in the community. In 1992 and 1995, it was successively introduced. Used in elderly and acute stroke patients, the results show that this balance scale has excellent In-Rater and Between-Rater reliability (ICC is 0.98). And with excellent internal consistency (Cronbach's α = 0.96); in 1996 Bogle and other scholars used the score of this balance scale to predict the probability of falling in the elderly, and found that when the score is below 45, compared to the score Those with a score of 45 or higher have a higher chance of falling. Although this scale cannot be used to predict whether the score is lower and the probability of falling is higher, but the clinical cutoff is provided to determine the possibility of a fall. Sex. Timed “Up & Go” Test – “Get-up and Go” Test The first time in 1986, Mathias and other scholars studied 40 elderly people with balance dysfunction, using photography to observe It is stood by a chair with a handle and walks on the trail of three meters, then turns back and performs the sitting action. This test combines daily function activities such as sitting, walking, turning and standing to sit, although research The results show that this is a fast and practical balanced function test, but its scoring standard is too short and its shortcomings, only according to the observer's subjective rating, the action execution is divided into five levels of 1 to 5 points, for the score results Only the extreme values of 1 point and 5 points have a more consistent consensus, but the definition of the intermediate score of 2 to 4 points is less objective.

雖然目前臨床檢測具有簡易、快速且有一定的信效度，但對老人跌倒的平衡能力評估仍有很大的限制，因為無論是Burg ScaleTest或是Time Up ＆ Go Test皆不能針對外界干擾的反應時間、反應力及姿勢調控做出評量，而且老人跌倒中有很大比例是在干擾情況下跌倒(例如：絆倒、撞倒)。另外在儀器部份，雖然國內外己開發許多平衡的評估及訓練系統，用工程製造的觀點來看這些系統的機電整合部份做的都有一定品質及創意，但從醫學的療效觀點來看這些系統恐有不適用於老人的平衡評量與復健，分析其理由概述如下幾點。Although the current clinical tests are simple, fast, and have certain reliability and validity, there is still a large limit to the assessment of the balance of the fall of the elderly, because neither Burg ScaleTest nor Time Up & Go Test can respond to external disturbances. Time, responsiveness, and posture adjustments are measured, and a large percentage of falls in the elderly are falling in the interference situation (eg, tripping, knocking down). In addition, in the instrument part, although many balanced evaluation and training systems have been developed at home and abroad, from the point of view of engineering manufacturing, the electromechanical integration of these systems has certain quality and creativity, but from the point of view of medical efficacy These systems may not be suitable for the balance assessment and rehabilitation of the elderly, and the reasons for the analysis are summarized as follows.

(a)大多使用傳統的「反應性控制」理論為設計依據，未考慮老年人的感覺動作機能已經退化的重要因素。(a) Most of the traditional "reactive control" theory is used as the basis for design, and important factors that have deteriorated the sensory function of the elderly have not been considered.

(b)未能設計預期性反應的平衡評量與復健模組；而預期性反應訓練方式是近年來對老人平衡訓練的趨勢。(b) Failure to design a balanced assessment and rehabilitation module for expected response; and the expected response training approach is the trend of balanced training for the elderly in recent years.

(c)未能提供篩檢功能以篩檢出潛在性跌倒的高危險族群老人。(c) Failure to provide a screening function to screen out high-risk groups of elderly people with potential falls.

(d)未考慮老年人的平衡訓練宜用較低的運動強度，特別是針對合併有其他疾病的虛弱老人。(d) Balance exercise that does not consider the elderly should use lower exercise intensity, especially for frail elderly with other diseases.

(e)給予老年人的平衡訓練方式過於複雜；例如：複雜的互動圖示及過於強調影音的虛擬互動方式均不適用於老人。(e) The method of balancing training for the elderly is too complicated; for example, complex interactive icons and virtual interactions that place too much emphasis on audio and video are not applicable to the elderly.

故綜合以上內容顯示國內現今復健科技人才對預防老人跌倒的平衡復健上，仍有許多待努力改善的空間，特別是能針對老人預防跌倒的研究課題上，應予以重新調整做出合理的研發定位以及投入臨床療效的研究。Therefore, the above content shows that there is still much room for improvement in the prevention and rehabilitation of the fall of the elderly in the prevention of the fall of the elderly. In particular, the research topic that can prevent falls in the elderly should be re-adjusted to make a reasonable Research and development positioning and research into clinical efficacy.

有鑑於此，提供一種評估老人站立時動態平衡能力及提供預期性訓練之系統實為必要。In view of this, it is necessary to provide a system for assessing the dynamic balance ability of the elderly while standing and providing predictive training.

本發明設計基本概念乃是偵測受測者在測試時左右兩側足底承重、兩足間之人體重心位置、重心移動速度、重心移動範圍等，更重要的是可將此些參數結合一復健訓練遊戲，來得到受側者受到預期性干擾後的左右兩側足底受力的平衡反應行為之參數，進而評估篩選受測者之跌倒傾向程度及分析其站立時動態平衡能力。The basic concept of the design of the present invention is to detect the bearing weight of the left and right sides of the test subject, the position of the center of gravity of the two feet, the moving speed of the center of gravity, the range of movement of the center of gravity, etc., and more importantly, the parameters can be combined. The rehabilitation training game is used to obtain the parameters of the balanced reaction behavior of the left and right sides of the affected side after the expected interference, and then evaluate the degree of fall tendency of the test subject and analyze the dynamic balance ability of the standing.

上述預設的跌倒危險群資料庫包含有具有不同跌倒危險程度的群組，譬如低度跌倒危險群、中度跌倒危險群及高度跌倒危險群，以對應有不同跌倒危險程度的老人，而上述群組的分組方式則是使用一統計結果來分組，即先針對一群受測者先行進行測試以取得分析資料，再觀察受測者實際狀況結合其分析資料，來劃分出幾種程度之跌倒危險程度群組，如有一老人經常跌倒，那該老人之分析資料就可視為經常跌倒的危險群組，以此分析資料為基礎畫出一範圍，就可劃分出該程度之跌倒危險程度群組；此種劃分也有助於後續復建訓練的安排，一旦所屬跌倒危險群經確定，對應的復健訓練遊戲亦因應啟動以配合受測者狀況提供適切相關的復健訓練。The above-mentioned default fall risk group database contains groups with different fall risk levels, such as low fall risk group, moderate fall risk group and high fall risk group, to correspond to elderly people with different fall risk levels. The grouping method of groups is to use a statistical result to group, that is, first test a group of subjects to obtain analysis data, and then observe the actual situation of the subject combined with the analysis data to classify several degrees of fall risk. Degree group, if an old man often falls, the analysis data of the old man can be regarded as a dangerous group that often falls. Based on the analysis data, a range can be drawn, and the fall risk degree group of the degree can be divided; This division also contributes to the arrangement of subsequent rehabilitation training. Once the fall risk group is determined, the corresponding rehabilitation training game is also activated to provide appropriate and relevant rehabilitation training in accordance with the condition of the subject.

本案所採用的復健訓練遊戲係基於預期性反應訓練方式考量，在復健訓練遊戲中提供預期性情境的刺激，使受測者可於一可控制情形下因應預期性的刺激進行復健訓練；例如，在遊戲中針對某一跌倒危險群設計有相對應閃躲困難度的障礙物，使受測者閃躲該等預設的障礙物，以達到預期的訓練效果。The rehabilitation training game adopted in this case is based on the expectation response training method, and provides the stimulus of the expected situation in the rehabilitation training game, so that the subject can perform the rehabilitation training in response to the expected stimulus in a controllable situation. For example, in the game, an obstacle corresponding to the difficulty of dozing is designed for a certain fall danger group, so that the subject can dodge the preset obstacles to achieve the desired training effect.

綜上所述，本發明提供了一種為老人平衡之視覺提示預期性訓練與即時同步評估系統。該系統特色為：(1)整合平衡評估與復健訓練這兩部份，不同於以往只能訓練或是只能評估的缺失，本系統可達到即時分析、同步訓練的效果；(2)平衡評估的部份：訊號接收不只侷限於傳統訊號感測器(例如：壓力感測器、溫度感測器、氣體感測器......)，亦可以接收來自人體生理訊號感測器(例如：測力板、加速規、傾斜計、肌電圖感測器......)所發出的訊號變化，進而測量人體之重心位置、加速度、傾斜角度或是肌電變化，搭配本發明專屬的分析軟體，進行分析評估；(3)訓練的部份：情境式或是虛擬實境之復健訓練，使用者能夠在特定情境下與測試平台做互動，增加參與感並且提升訓練意願，可以選擇特定部位或是動作，來加以訓練，並且可更換訊號擷取與復健訓練的種類；(4)本案系統所涉硬體價位便宜，前置作業簡單，所需場地小，可解決目前評估平衡儀器昂貴及不易攜帶與校正之缺點。因此本發明具有實用性及創造性，能有效改善習知技藝之缺失，進而達成發展本發明之目的。In summary, the present invention provides a visual alert expectation training and instant synchronization assessment system for the elderly.
