Capacitive resistive electric transfer (CRET), a radiofrequency at 448 kHz, increases flexibility in quadricep muscles of human athletes. To assess whether CRET would result in clinical and biomechanical improvements in horses with thoracolumbar pain, 18 sport horses were divided into two groups: CRET ( = 9), subjected to four CRET sessions, during two consecutive weeks, and SHAM ( = 9), subjected to the same procedure with the device off. Clinical examination and accelerometry were performed before and after the four sessions. During the study, horses were in training and in active competition, and did not receive any other treatment. Mann-Whitney and a Wilcoxon matched pair tests were used to compare between the SHAM and CRET groups and before and after the intervention, respectively. CRET horses showed increased dorsoventral ( < 0.002), mediolateral and total power ( < 0.01) after the intervention, suggesting increased back flexibility. SHAM horses did not show any of these modifications after the intervention. No changes were found in the dorsoventral displacement of the gravity center in either group. Thoracolumbar pain decreased one degree after CRET ( = 0.002), and it did not change after SHAM. Epaxial muscle pain decreased two degrees after CRET ( = 0.03) and one degree after SHAM ( = 0.01). These results reflected that CRET therapy would increase back flexibility and decrease thoracolumbar and epaxial pain.
电容电阻式电转移（CRET），一种448千赫兹的射频技术，可提高人类运动员股四头肌的柔韧性。为了评估CRET是否会使患有胸腰椎疼痛的马匹在临床和生物力学方面得到改善，18匹运动马被分为两组：CRET组（n = 9），连续两周接受4次CRET治疗；假治疗组（SHAM，n = 9），在设备关闭的情况下接受相同的操作。在4次治疗前后进行临床检查和加速度测量。在研究期间，马匹处于训练和积极比赛状态，未接受任何其他治疗。分别使用曼-惠特尼检验和威尔科克森配对检验来比较假治疗组和CRET组以及干预前后的情况。干预后，CRET组马匹的背腹向（P < 0.002）、内外侧和总功率增加（P < 0.01），表明背部柔韧性增加。假治疗组马匹在干预后未出现任何这些变化。两组的重心背腹向位移均未发现变化。CRET治疗后胸腰椎疼痛减轻了一度（P = 0.002），假治疗后未改变。CRET治疗后轴上肌肉疼痛减轻了两度（P = 0.03），假治疗后减轻了一度（P = 0.01）。这些结果表明，CRET疗法可增加背部柔韧性，减轻胸腰椎和轴上肌肉疼痛。
