Kinesio tape (KT) is an elastic therapeutic tape used for treating sports-related injuries and a number of other disorders. To date, the objective evidence to link pathophysiological effects and actual reactions triggered by KT is limited.
To explore the effect of KT on the lumbar paraspinal muscles by magnetic resonance (MR) elastography.
Prospective observational study.
Sixty-six asymptomatic volunteers with 31 women and 35 men.
FIELD STRENGTH/SEQUENCE: 3.0T MRI and elastography with vibration frequency of 120 Hz.
The 5-cm-width KT with full tension was placed on a single side of the lumbar paraspinal muscle. The taping side and adhering direction were randomly decided. Two rectangular regions of interest (ROIs) of 5- and 2.5-cm-width were positioned at the bilateral paraspinal regions from the L2 to L4 level on the confidence map of MR elastography before and after KT taping. The mean shear stiffness values of the ROIs at the superficial, middle, and deep depths were recorded; then the differences between the taping and reference sides were calculated.
Paired t-test and Pearson correlations were used to evaluate the stiffness changes after KT application and intraoperator errors of the stiffness measures on the reference side, respectively.
A significant decrease in the muscle stiffness value between taping and reference sides (-0.71 kPa ± 0.60 with KT and -0.25 kPa ± 0.78 without KT, P < 0.0001 for 5-cm ROI; -0.67 kPa ± 1.12 with KT and -0.16 kPa ± 1.17 without KT, P = 0.0004 for 2.5-cm ROI) was found in the superficial depth, but no significant differences in the middle and deep depths (P = 0.25 and P = 0.79 for 5-cm ROI; P = 0.09 and P = 0.67 for 2.5-cm ROI, respectively). There were no significant differences of muscle stiffness differences between gender (P = 0.11 for superficial, P = 0.37 for middle, P = 0.78 for deep) and taping direction (P = 0.18 for superficial, P = 0.13 for middle, P = 0.15 for deep).
Our results demonstrate that KT can reduce the MR elastography-derived shear stiffness in the superficial depth of paraspinal muscles.

运动贴布（KT）是一种弹性治疗贴布，用于治疗与运动相关的损伤和许多其他疾病。迄今为止，将病理生理学效应与 KT 引发的实际反应联系起来的客观证据有限。
通过磁共振弹性成像（MR 弹性成像）探讨 KT 对腰椎旁脊柱肌肉的影响。
前瞻性观察性研究。
66 名无症状志愿者，其中女性 31 名，男性 35 名。
场强/序列：3.0T MRI 和以 120Hz 振动频率进行的弹性成像。
将 5cm 宽、全张力的 KT 贴布贴在腰椎旁脊柱肌肉的一侧。贴布侧和附着方向随机决定。在 MR 弹性成像置信图上，在 L2 至 L4 水平的双侧旁脊柱区域定位 5cm 和 2.5cm 宽的两个矩形感兴趣区（ROI）。记录 ROI 各深度（浅层、中层和深层）的平均剪切刚度值；然后计算贴布侧与参考侧之间的差异。
使用配对 t 检验和 Pearson 相关性分别评估 KT 应用后的刚度变化和参考侧刚度测量的操作者内误差。
在浅层，与参考侧相比，贴布侧的肌肉硬度值显著降低（KT 侧为-0.71kPa±0.60，无 KT 侧为-0.25kPa±0.78，P<0.0001；2.5cm ROI 为-0.67kPa±1.12，无 KT 侧为-0.16kPa±1.17，P=0.0004），但在中层和深层未见明显差异（P=0.25 和 P=0.79，5cm ROI；P=0.09 和 P=0.67，2.5cm ROI）。在性别（浅层 P=0.11，中层 P=0.37，深层 P=0.78）和贴布方向（浅层 P=0.18，中层 P=0.13，深层 P=0.15）之间，肌肉硬度差异无显著差异。
我们的结果表明，KT 可以降低脊柱旁肌肉的 MR 弹性成像衍生剪切刚度在浅层。
