The effect of tibial fixation on the movement of the talus during the tibiotarsal axial traction technique (TATT) is unknown. The aim was to evaluate the effect on the tibiotarsus when applying three different intensities of TATT force with or without tibial fixation in healthy subjects, and to assess the reliability of detecting the different forces applied. Also, the discomfort generated during the technique would be analysed. A cross-sectional study was conducted in thirty lower limbs. Three magnitudes of TATT force in an open-packed position were applied in tibial fixation and non-fixation conditions. The axial traction movement was measured by ultrasound, and the magnitudes of the force applied during low-medium and high TATT force were recorded in both conditions. Patients were asked about the level of discomfort perceived during the technique. The most significant distance increase (mm) was observed in the tibial fixation condition at all magnitudes of the TATT (F = 102.693, < 0.001). The discomfort sensation (numeric rating scale, "NRS") was higher in the non-fixation condition ( > 0.05). The application of the technique showed good reliability (>0.75 ICC) for the detection of the applied force. The TATT in the tibial fixation condition produced more significant axial movement of the talus (mm) relative to the tibia than the non-tibial fixation condition did. The detection of the magnitudes of movement showed good reliability (ICC: 0.75 to 0.92). The technique was well tolerated at all force magnitudes, with the tibial fixation condition being the most tolerable.
在胫距轴向牵引技术（TATT）过程中，胫骨固定对距骨运动的影响尚不清楚。本研究旨在评估在健康受试者中，施加三种不同强度的TATT力且有无胫骨固定时对胫距关节的影响，并评估检测所施加不同力的可靠性。此外，还将分析该技术过程中产生的不适感。对30条下肢进行了横断面研究。在胫骨固定和非固定条件下，于开放位施加三种大小的TATT力。通过超声测量轴向牵引运动，并记录两种条件下低、中、高TATT力时所施加力的大小。询问患者该技术过程中感觉到的不适程度。在所有TATT力大小情况下，胫骨固定条件下观察到的距离增加最为显著（毫米）（F = 102.693，P < 0.001）。非固定条件下的不适感（数字评分量表，“NRS”）更高（P > 0.05）。该技术的应用在检测所施加力方面显示出良好的可靠性（ICC > 0.75）。与非胫骨固定条件相比，胫骨固定条件下的TATT使距骨相对于胫骨产生了更显著的轴向运动（毫米）。运动大小的检测显示出良好的可靠性（ICC：0.75至0.92）。在所有力大小情况下，该技术耐受性良好，其中胫骨固定条件下耐受性最佳。
