在基于旋转的运动（如高尔夫挥杆）后提供超声生物反馈可用于增加外腹壁的肌肉厚度。如代表性结果所示，超声生物反馈的单次试验可导致整个高尔夫挥杆过程中斜肌活动的短期增加。
以前的研究还使用了在动态任务期间用松紧带固定的B型超声20。这是在个人在跑步机上行走时测量的。与目前的方法类似，作者将B模式视频减少到静止图像的较小百分比以?...

外腹壁的肌肉包括外斜肌、内斜肌和横腹肌。外斜肌进行侧屈和对侧躯干旋转，而内斜肌进行同侧躯干旋转。横腹是腹部肌肉组织的最深层，它的作用是增加腹内压，增加脊柱的节段稳定性1。这些肌肉的适当功能对于降低腰痛风险和提高运动表现非常重要，因为核心稳定性可以通过四肢增加力量和力量2.
在高尔夫、网球、棒球或垒球等强调躯干旋转的运动中，对核心肌肉的需求很高。例如，在高尔夫挥杆期间，当使用表面肌电图测量时，身体小径侧的斜肌在最大自主等长收缩 （MVIC） 的 64% 处达到峰值，而铅斜肌在 54% MVIC3 处达到峰值。躯干旋转是影响高尔夫击球距离和准确性的关键因素4.高尔夫挥杆的压力和对核心肌肉活动的高需求可能会导致腰痛，这是高尔夫5 中最常见的伤害。此外，在患有腰痛的精英高尔夫球手中，与健康个体相比，在高尔夫挥杆期间外斜活动的时间延迟6.另一项使用肌电图的研究发现，与没有腰痛的高尔夫球手相比，腰痛高尔夫球手的竖脊髓发作更早7，这表明关注前外侧肌肉可能是有益的。因此，测量高尔夫挥杆期间腹部肌肉活动的程度和时间对于提高表现和降低腰痛的风险非常重要。
康复超声通常用于评估外侧腹壁肌肉，因为这种肌肉组织的分层性质8，9，10。在仰卧位或功能更实用的高尔夫挥杆设置姿势有和没有腰痛的大学高尔夫球手的横腹激活方面没有差异11.然而，横腹活动只是高尔夫挥杆的一个组成部分，旋转对该人群可能更重要。以前的文献使用松紧带和泡沫块将超声换能器固定在腹部，允许在动态运动（例如单腿下蹲或步态）期间对核心肌肉组织进行超声评估8.在动态运动期间应用超声波已被证明具有可接受的出色可靠性12。该技术可用于测量高尔夫挥杆或其他运动特定任务期间侧腹壁的厚度变化。虽然表面肌电图通常用于测量肌肉的电活动，但这在腹部区域不太可行。分层解剖结构导致肌肉之间的串扰，并且不允许核心13的各个肌肉层的视觉表示。与核心肌肉组织的表面肌电图等替代方案相比，超声波具有优势，因为它可以表示每个单独的肌肉，同时还可以提供反馈图像14。
由于超声波实时提供感兴趣的肌肉图像，因此它也可以用作视觉生物反馈的工具。与单独的言语提示相比，超声生物反馈提高了增加横腹和腰椎多裂肌厚度的能力15，16。此外，在有和没有腰痛的高尔夫球手中，实时超声生物反馈会增加仰卧位和高尔夫设置位置的横腹厚度11.仰卧位的生物反馈训练也转化为直立负荷任务17.需要更多的研究来确定生物反馈训练所需的频率和持续时间，因为大多数研究是单次或短期训练方案15。由于超声波已被应用于功能任务，并且有证据表明高尔夫球手可以在设置位置增加深部肌肉的预激活，因此接下来应该研究使用超声波生物反馈来增加高尔夫挥杆期间的斜肌厚度。
因此，该方法旨在使用超声波作为反馈机制，以改善高尔夫挥杆过程中腹部斜肌的激活和时机。

与单独的言语提示相比，使用超声生物反馈与言语提示相比可以增加肌肉厚度，并且可以增强运动，身体活跃人群的传统康复技术。可以使用与视频同步的逐帧分析来应用亮度模式（B模式）超声，以了解这些动态任务期间的肌肉厚度变化。超声视觉生物反馈已在外腹壁肌肉的静态位置建立。然而，通过使用松紧带和泡沫块将换能器固定在腹部，生物反馈可以应用于终身运动中普遍存在的更具体的任务，例如高尔夫。为了分析高尔夫挥杆期间的肌肉活动，可以比较肌肉厚度的变化。在整个任务过程中，厚度必须增加，表明肌肉更加活跃。这种方法允许临床医生立即为患者重播超声视频，作为指导感兴趣肌肉适当活动的视觉工具。例如，超声波可用于靶向外部和内部斜肌，它们在挥动高尔夫球杆或任何其他旋转运动或活动中起着重要作用。这种方法旨在增加高尔夫挥杆过程中的斜肌厚度。此外，可以通过指示患者在特定时间点（例如下摆开始）收缩腹部肌肉来确定肌肉收缩的时间，目的是改善任务期间的肌肉放电模式。

Providing Visual Biofeedback Using Brightness Mode Ultrasound During a Golf Swing

亮度模式超声可用于在高尔夫挥杆期间提供外腹壁肌肉的视觉生物反馈。摆动后的视觉和语言指导可以增加肌肉激活以及外斜和内斜的时间。

超声波生物反馈可以帮助增加核心肌肉的激活和时间，这对于运动表现和降低腰痛等受伤风险都很重要。使用超声波进行生物反馈的一个主要优点是它提供了实时图像。该图像以及口头提示可以帮助患者正确使用肌肉。这种方法也可以直接应用于其他旋转运动，如棒球或垒球挥杆，或网球正手。首先，使用开/关按钮打开并打开超声设备。然后按键盘上的“患者”按钮添加新患者，并选择屏幕左侧的“新患者”。输入所需的患者 ID 号，确保选择 MSK 作为检查类型，然后单击注册。退出以开始考试，然后进入 B 模式。通过将线性探头的头部穿过皮带中间的水平狭缝，将线性阵列探头放置在松紧带中。接下来，应用一到两个泡沫块将换能器固定到位。将超声凝胶涂在线性换能器上。将换能器放在腹侧壁上，距脐外侧约 10 厘米。使用魔术贴将安全带固定在参与者身上，确保安全带足够紧，以便传感器垂直于腹侧壁固定。如有必要，调整超声的深度和增益，以获得外斜、内斜和横腹的筋膜边界和肌肉厚度的清晰图像，确保横向腹部的筋膜边界在此纵向视图中在屏幕边缘可见。图像清晰后，以反映他们将完成的任务的方式定位患者，例如，如果他们进行高尔夫挥杆，请让他们站在设置位置。然后按冻结，然后按存储以捕获静态图像。将其保存到患者的检查中并实时测量或稍后访问以测量静息肌肉厚度。再次选择“冻结”以返回到实时映像。按“存储”开始以B模式视频录制。在每次尝试后提供口头提示或说明，同时根据需要调整提示。在屏幕的右下角，检查计时器是否开始并以亮绿色突出显示，表示正在捕获视频。再次按“商店”结束视频并将其保存到考试中。如果图像变得模糊，请根据需要调整超声探头在泡沫块内的位置。每次试验后，检查视频的图像清晰度，如果图像在任何时候变得无回声，则表明超声探头在摆动过程中移动。排除试验并重新测量。每次摆动后，将患者定位在他们可以查看超声屏幕的位置。打开要测量的第一个静止图像。使用光标，将鼠标悬停在活动图像下方库中的所需图像上，然后单击 Enter。 单击测量一次以打开测量工具，然后在光标位于感兴趣肌肉的上筋膜边界上时单击 Enter。一旦光标位于下筋膜边框上，再次单击 Enter。捕获所需数量的视频后，打开要处理的第一个视频。使用光标将鼠标悬停在活动图像下方库中的所需图像上，然后单击 Enter 按钮。调整B模式视频中的观看帧，直到达到第一帧并确定所需的采样率。打开所需框架后，使用测量工具单击按钮一次以打开该工具。将光标放在感兴趣肌肉的上筋膜边界上，然后单击 Enter 以放置测量的第一端。将测量线拖动到感兴趣肌肉的下筋膜边界，然后再次单击 Enter 以完成测量。然后按商店保存测量的图像。将测量记录在电子表格中，该电子表格的组织包括参与者或患者的姓名/编号、帧号和厚度测量值。返回到原始 B 模式视频帧并滚动到要分析的下一帧。重复测量步骤，直到测量到所有所需的帧。要确定特定时间点的活化率，请如前所述测量厚度，然后将该值除以静止图像厚度。为了确定在提供生物反馈时，组合斜厚度是否在50%时间点增加，计算了活化率。非生物反馈试验显示厚度为1.685，而生物反馈的值为1.739。因此，可以推断，在高尔夫挥杆的50%持续时间下，生物反馈导致斜肌激活的小幅增加。通过超声生物反馈，能够使用通俗的术语来帮助患者理解图像非常重要。解释目标是通过它们的核心旋转以产生动力。按照这个程序，我们还可以看看横腹的肌肉厚度。这可以向我们展示患者在动态运动期间的深层核心肌肉活动和脊柱稳定性。
