Abstract:
Instrument-assisted soft tissue mobilization (IASTM) stimulates soft subcutaneous tissues by applying pressure to the skin with a specialized bar or spurtle-like instrument. No studies have verified whether several weeks of continuous IASTM alone can alter joint flexibility and musculotendinous properties in healthy participants. We examined the effect of a 6-week IASTM program on joint flexibility and the musculotendinous properties of the lower limbs. Fourteen healthy men (aged 19-35 years) who participated in a 6-week IASTM program (3 days weekly) for the soft tissue of the posterior aspect of one lower leg were included. The other leg served as the control. Before and after the intervention, we measured the maximal ankle joint dorsiflexion angle (dorsiflexion range of motion: DFROM) and maximal passive torque (MPT), a measure of stretch tolerance. We measured muscle and tendon stiffness using shear wave elastography on the gastrocnemius and Achilles tendon. IASTM significantly increased the DFROM and MPT (p < 0.05 for both). However, no significant changes were observed in muscle and tendon stiffness. None of the parameters changed significantly in the control group. The 6-week IASTM program increased stretch tolerance and joint flexibility but did not change muscle and tendon stiffness.
摘要:
器械辅助的软组织动员(IASTM)通过使用专门的棒或类似spurtle的器械向皮肤施加压力来刺激软皮下组织。没有研究证实单独连续几周的IISTM是否可以改变健康参与者的关节柔韧性和肌肉肌腱特性。我们检查了为期6周的IISTM计划对关节柔韧性和下肢肌肉肌腱特性的影响。包括14名健康男性(19-35岁),他们参加了为期6周的IISTM计划(每周3天),用于一条小腿后部的软组织。另一条腿作为对照。干预前后,我们测量了最大踝关节背屈角(背屈运动范围:DFROM)和最大被动扭矩(MPT),拉伸公差的度量。我们使用剪切波弹性成像在腓肠肌和跟腱上测量肌肉和肌腱的刚度。IASTM显著增加了DFROM和MPT(两者的p<0.05)。然而,肌肉和肌腱僵硬度无明显变化.对照组中的参数均无明显变化。为期6周的IISTM计划增加了拉伸耐受性和关节柔韧性,但没有改变肌肉和肌腱的刚度。
