This study aimed to investigate the acute and prolonged effects of dermal suction on joint range of motion (ROM) and passive muscle stiffness. Eight-minute dermal suction was prescribed for the quadriceps femoris in 15 participants. Hip extension ROM, knee flexion ROM, and passive muscle stiffness of the rectus femoris (RF) and vastus lateralis (VL) were measured before and immediately, 30 min, 60 min, 120 min, 24 h, and 48 h after dermal suction. Passive muscle stiffness was measured using shear wave elastography. Hip extension ROM significantly increased immediately (p = 0.032), 60 min (p = 0.029), and 120 min (p = 0.031) after dermal suction compared with before dermal suction; however, it was not significantly different at 30 min, 24 h, and 48 h after dermal suction (p > 0.05). Passive muscle stiffness of the RF and VL and knee flexion ROM did not significantly change at any measurement time compared with before dermal suction (p > 0.05). Our preliminary results suggest that dermal suction improves hip extension ROM immediately after dermal suction of the quadriceps femoris, followed by a return to the pre-prescription level 30 min after. However, the effect was prolonged for 120 min and disappeared before 24 h.
本研究旨在探讨皮肤吸引对关节活动范围（ROM）和被动肌肉僵硬度的急性和长期影响。对15名参与者的股四头肌进行8分钟的皮肤吸引。在皮肤吸引前以及皮肤吸引后即刻、30分钟、60分钟、120分钟、24小时和48小时测量髋关节伸展ROM、膝关节屈曲ROM以及股直肌（RF）和股外侧肌（VL）的被动肌肉僵硬度。使用剪切波弹性成像测量被动肌肉僵硬度。与皮肤吸引前相比，皮肤吸引后即刻（p = 0.032）、60分钟（p = 0.029）和120分钟（p = 0.031）时髋关节伸展ROM显著增加；然而，在皮肤吸引后30分钟、24小时和48小时时无显著差异（p > 0.05）。与皮肤吸引前相比，RF和VL的被动肌肉僵硬度以及膝关节屈曲ROM在任何测量时间均无显著变化（p > 0.05）。我们的初步结果表明，对股四头肌进行皮肤吸引后，髋关节伸展ROM在皮肤吸引后即刻得到改善，随后在30分钟后恢复到吸引前水平。然而，这种效果持续了120分钟，并在24小时前消失。
