Description
本發明係與步態訓練技術有關,特別是指一種即時調整步態訓練參數之方法。 The present invention relates to gait training technology, in particular to a method for real-time adjustment of gait training parameters.
一般於步態訓練的過程中,通常會藉由步態訓練設備來輔助使用者進行步態訓練。 Generally, in the process of gait training, a gait training device is usually used to assist the user in gait training.
請參閱如美國第US 8147436號專利所提供之一種動力矯型器,如所述專利中圖7所示,其主要是蒐集6位正常人主動出力的步行數據,作為步態軌跡的理想模型,並於步態軌跡外圍規劃隧道型態的容許誤差空間,藉此提供使用者於步態訓練中,達到接近理想模型的訓練效果。 Please refer to a kind of dynamic orthosis provided by U.S. Patent No. US 8147436, as shown in Figure 7 of the said patent, which mainly collects the walking data of 6 normal people who actively exert force, as an ideal model of gait trajectory, And the allowable error space of the tunnel type is planned on the periphery of the gait trajectory, so as to provide the user with a training effect close to the ideal model in the gait training.
但是,如上述美國第US 8147436號專利中,將理想模型套用至所有使用者進行訓練的技術,並沒有考量到使用者個體化差異來規劃運動模型,因此,該專利中規劃出的理想模型較難以適合不同使用者。 However, as in the above-mentioned U.S. Patent No. US 8147436, the technology of applying the ideal model to all users for training does not take into account the individual differences of users to plan the exercise model. Therefore, the ideal model planned in this patent is relatively Difficult to adapt to different users.
另外,請參閱如中國第CN 113244084A號專利所提供之一種可適應性主動訓練系統,如所述專利中圖6所示,其主要包含感測模塊、控制模塊及運動模塊,通過記錄用戶肌力放鬆被外骨骼帶動時的各區段生理訊號,計算各區段的生理訊號閾值,並於訓練中依據用戶的生理狀態信號,即時調整訓練難度。 In addition, please refer to the adaptive active training system provided by the Chinese patent No. CN 113244084A, as shown in Figure 6 of the said patent, which mainly includes a sensing module, a control module and a motion module, by recording the user's muscle strength Relax the physiological signals of each section when being driven by the exoskeleton, calculate the physiological signal threshold of each section, and adjust the training difficulty in real time according to the user's physiological state signal during training.
不過,如上述中國第CN 113244084A號專利中,僅針對用戶本身的步態數據做為參考,並未參考正常人或其他用戶的步態數據,因此,該專利中所規劃出的訓練模型,無法達到最佳化的步態訓練效果。 However, as in the above-mentioned Chinese Patent No. CN 113244084A, only the gait data of the user itself is used as a reference, and no reference is made to the gait data of normal people or other users.

In order to describe the technical characteristics of the present invention in detail, hereby aim at the following preferred embodiment, and describe it as follows in conjunction with the drawings, wherein, as shown in Figure 1-2, the
在本較佳實施例中,如圖2a所示,該步態訓練包含至少一步態週期,該步態週期對應於其中一隻腳的步態軌跡,該步態軌跡係模擬由人類行走時右腳跟著地開始到左腳趾離地、左腳跟著地到右腳趾離地最後又回到右腳跟著地的過程,圖2b、2c、2d、2e、2f、2g、3、3a、3b、3c、3d、3e的橫軸對應於圖2a的步態週期,將圖上的數據共分為100等分,以使用者的單一隻腳之腳跟觸地的位置對應於步態週期的起始點(即橫軸標示0的資料點),而同一隻腳之腳跟再次觸地之前的位置對應於橫軸第99的資料點。 In this preferred embodiment, as shown in Figure 2a, the gait training includes at least one gait cycle, which corresponds to the gait trajectory of one of the feet, which is simulated by a human when walking on the right The process from heel strike to left toe off the ground, left heel to right toe off the ground and finally back to right heel strike, Figure 2b, 2c, 2d, 2e, 2f, 2g, 3, 3a, 3b, 3c , 3d, and 3e correspond to the gait cycle in Figure 2a, divide the data on the graph into 100 equal parts, and use the position where the heel of the user's single foot touches the ground corresponds to the starting point of the gait cycle (that is, the data point marked 0 on the horizontal axis), and the position before the heel of the same foot touches the ground again corresponds to the 99th data point on the horizontal axis.
如圖1、2b、2c、2d及2e所示,該步驟(a)該感測單元蒐集該第一使用者於肌肉放鬆狀態下在一步態訓練中所測得的一第一使用者肌肉放鬆步態數據(如圖2b),以及該第一使用者於主動出力狀態下在該步態訓練所測得的第一使用者主動出力步態數據(如圖2c),該控制單元藉由該第一使用者主動出力步態數據與該第一使用者肌肉放鬆步態數據之比值,進而建立一標準運動模型(如圖2d)。此處「肌肉放鬆狀態」指的是使用者在該步態訓練時不需出力,僅藉由步態訓練設備100的控制單元驅動訓練單元,進而帶動使用者的雙腳擺
動,「主動出力狀態」指的是該訓練單元運作的過程中,使用者的雙腳須主動出力。
As shown in Figures 1, 2b, 2c, 2d and 2e, in this step (a), the sensing unit collects a first user's muscle relaxation measured in the gait training in the muscle relaxation state of the first user Gait data (as shown in Figure 2b), and the first user's active effort gait data (as shown in Figure 2c) measured in the gait training under the active exertion state of the first user, the control unit uses the The ratio of the first user's active exertion gait data to the first user's muscle relaxation gait data is used to establish a standard motion model (as shown in FIG. 2d ). The "muscle relaxation state" here means that the user does not need to make any effort during the gait training, and only the control unit of the
在本較佳實施例中,為了提升各項數據的穩定性,該第一使用者的取樣數量係以複數個為例,藉由複數個該第一使用者主動出力步態數據之平均值與複數個該第一使用者肌肉放鬆步態數據之平均值之比值,進而建立該標準運動模型(如圖2e)。在其他較佳實施例中,若在一個該第一使用者的該第一使用者主動出力步態數據與該第一使用者肌肉放鬆步態數據就足以具有代表性的情況下,該第一使用者的數量亦能以一為例,故該第一使用者的數量並不僅以本較佳實施例為限。 In this preferred embodiment, in order to improve the stability of various data, the number of samples of the first user is taken as an example, and the average value of the first user's active effort gait data and The ratio of the average value of the plurality of muscle relaxation gait data of the first user is used to establish the standard motion model (as shown in FIG. 2e ). In other preferred embodiments, if the first user's active effort gait data and the first user's muscle relaxation gait data of the first user are representative enough, the first user The number of users can also be taken as one, so the number of the first user is not limited to this preferred embodiment.
在本較佳實施例中,如圖2a、2f及2g所示,該步態週期主要分為一重心轉移區間F1、一髖屈曲區間F2及一膝伸直區間F3,該重心轉移區間F1係位於該步態週期中0-40等分,該髖屈曲區間F2係位於該步態週期中45-70等分,該膝伸直區間F3係位於該步態週期中80-99等分。 In this preferred embodiment, as shown in Figures 2a, 2f and 2g, the gait cycle is mainly divided into a center of gravity transfer interval F1, a hip flexion interval F2 and a knee extension interval F3, and the center of gravity transfer interval F1 is Located in the 0-40 equal division of the gait cycle, the hip flexion interval F2 is located in the 45-70 equal division of the gait cycle, and the knee extension interval F3 is located in the 80-99 equal division of the gait cycle.
其中,以該第一使用者之右腳為例(左腳的判斷方式亦同,在此不再贅述),如圖2f所示,當位於該重心轉移區間F1時,該第一使用者之右腳踩踏該右腳力量感測器102所感測的數值大於一模型閾值(該第一使用者100%主動出力預測值),當位於該髖屈曲區間F2時,該右腳踩踏該右腳力量感測器102所感測的數值小於該模型閾值,如圖2g所示,當位於該膝伸直區間F3時,該右膝壓力感測器104小於該模型閾值。
Wherein, taking the right foot of the first user as an example (the judging method of the left foot is also the same and will not be repeated here), as shown in Figure 2f, when the center of gravity transfer interval F1 is located, the first user The value sensed by the right foot stepping on the right
在本較佳實施例中,如圖2h所示,該左膝壓力感測器103及該右膝壓力感測器104分別具有一上感測元件105及一下感測元件106(由於該左、右膝壓力感測器103、104之上、下感測元件105、106係為相同元件且具有相同的
配置關係,故僅以一圖式作為該該左膝壓力感測器103及該右膝壓力感測器104之示意),其中,假設該上感測元件105測得的壓力數值為P K1,該下感測元件106測得的壓力數值為P K2,該上感測元件105的中心點與該下感測元件106之下端面的最短距離為X 1(在此實施例中為100mm),該下感測元件106的中心點與該下感測元件106之下端面的最短距離為X 2(在此實施例中為10mm),則該左膝壓力感測器103(或該右膝壓力感測器104)的壓力中心位置=
如圖1、3所示,該步驟(b)該控制單元取得一第二使用者的運動模型,該第二使用者運動模型包含該第二使用者於肌肉放鬆狀態下在該步態訓練所測得的一第二使用者肌肉放鬆步態數據,藉由該第二使用者肌肉放鬆步態數據結合該標準運動模型,進而推估一個人化訓練模型(如圖3)。在本較佳實施例中,如圖3a所示,係以該個人化訓練模型推估出10%、15%、20%、25%、30%、40%、50%、60%、70%、80%、90%及100%的難度曲線(圖3a中僅標示該100%難度曲線L1及該10%難度曲線L12),藉此建立不同難度的該個人化訓練模型,該些難度曲線可依需求進行調整,因此該些難度曲線不僅以本較佳實施例為限。 As shown in Figures 1 and 3, in step (b), the control unit acquires a second user's motion model, which includes the second user's movement in the gait training center in a state of muscle relaxation. The measured muscle relaxation gait data of a second user is combined with the standard motion model to estimate a personalized training model (as shown in FIG. 3 ). In this preferred embodiment, as shown in Figure 3a, the personal training model is used to estimate 10%, 15%, 20%, 25%, 30%, 40%, 50%, 60%, 70% , 80%, 90% and 100% difficulty curves (only the 100% difficulty curve L1 and the 10% difficulty curve L12 are marked in FIG. It can be adjusted according to requirements, so these difficulty curves are not limited to this preferred embodiment.
其中,以右腳來說,由於在該重心轉移區間F1係為右腳向下踩踏的階段,因此該右腳力量感測器102所測得的數值越高,表示該個人化訓練模型的難度越高,當該右腳力量感測器102所測得的數值越低,則表示該個人化訓練模型的難度越低,因此在約莫該步態週期0-40之間,位於最上方的曲線為該100%難度曲線L1,最下方的曲線為該10%難度曲線L12,而在該臗屈曲區間F2及該膝伸直區間F3係為右腳抬起的階段,因此,當該右腳力量感測器102
所測得的數值越低,表示該個人化訓練模型的難度越高,當該右腳力量感測器102所測得的數值越高,則表示該個人化訓練模型的難度越低,因此在約莫該步態週期45-100之間,位於最下方的曲線為該100%難度曲線L1,最上方的曲線為該10%難度曲線L12。
Wherein, taking the right foot as an example, since the center of gravity transfer interval F1 is the stepping down stage of the right foot, the higher the value measured by the right
在本較佳實施例中,如圖3b、3c、3d、3e所示,由不同難度的該個人化訓練模型中推估最適合該第二使用者的該個人化訓練模型的方式,首先,該第二使用者位於肌肉放鬆狀態,以右腳為例,由該右腳力量感測器102所得的數值,得到該第二使用者於肌肉放鬆狀態下時,在該步態週期中的一肌肉放鬆狀態最大值及一肌肉放鬆狀態最小值(如圖3b所示)再藉由該標準運動模型推估出該第二使用者於主動出力時,在該步態週期中的一預測主動出力最大值及一預測主動出力最小值(如圖3c所示),再以該第二使用者於主動出力狀態下由該右腳力量感測器102所得的數值,得到該第二使用者主動出力時,在該步態週期中的一實際主動出力最大值及一實際主動出力最小值(如圖3d所示),並分別將該實際主動出力最大值、該預測主動出力最大值及該肌肉放鬆狀態最大值帶入一重心轉移區間計算公式,以及分別將該實際主動出力最小值、該預測主動出力最小值及該肌肉放鬆狀態最小值帶入一髖屈曲區間計算公式,得到該重心轉移區間及該髖屈曲區間的出力程度,再由較低的出力程度推薦適合的該個人化訓練模型(如圖3e所示),其具體計算方式如下:該重心轉移區間計算公式:該重心轉移區間F1的出力程度。
In this preferred embodiment, as shown in Figures 3b, 3c, 3d, and 3e, the method of estimating the most suitable personalized training model for the second user from the personalized training models of different difficulties, first, The second user is in a state of muscle relaxation. Taking the right foot as an example, the value obtained by the right
在本較佳實施例中,如圖3c及3d所示,該第二使用者在該重心轉移區間F1的出力程度=。 In this preferred embodiment, as shown in Figures 3c and 3d, the degree of effort of the second user in the center of gravity transfer interval F1 = .
髖屈曲區間計算公式:該髖屈曲區間F2的出力程度。 Calculation formula for hip flexion range: The degree of effort in the hip flexion zone F2.
在本較佳實施例中,如圖3c及3d所示,該第二使用者在該髖屈曲區間F2的出力程度=。 In this preferred embodiment, as shown in Figures 3c and 3d, the degree of effort of the second user in the hip flexion zone F2 = .
由於該髖屈曲區間F2的出力程度小於該重心轉移區間F1的出力程度,故選擇以該髖屈曲區間F2的出力程度推薦適合的該個人化訓練模型,例如將圖3a中80%的難度曲線所代表的模型作為該個人化訓練模型。 Since the output of the hip flexion zone F2 is smaller than the output of the center of gravity transfer zone F1, the individualized training model is recommended based on the output of the hip flexion zone F2, for example, the 80% difficulty curve in Figure 3a The represented model serves as the personalized training model.
