Instrument-Assisted Soft Tissue Mobilization (IASTM) is a non-invasive therapeutic technique used to theoretically aid in scar tissue breakdown and absorption, fascial mobilization, and improved tissue healing. Researchers have hypothesized that utilizing IASTM will improve muscular efficiency and performance; yet previous Investigations has been focused on treating injury.
The purpose of this investigation was to explore the effects of IASTM on muscle performance to assess if typical treatment application affected measures of muscular performance.
A pretest-posttest randomized control design.
A convenience sample of 48 physically active adults (mean age 24 ± 4 years), randomly assigned to one of three groups: quadriceps treatment group, triceps surae treatment group, or control group.
Participants performed a five-minute warm-up on a Monark bicycle ergometer before performing three countermovement vertical jumps (CMJ). Immediately after, the IASTM treatment was applied by one researcher for three minutes on each leg at the specified site (e.g., quadriceps) for those assigned to the treatment groups, while the control group rested for six minutes. Immediately following treatment, participants performed three additional CMJs. Pre- and post-testing included measures of vertical jump height (JH), peak power (PP) and peak velocity (PV).
There were no statistically significant differences found between treatment groups in JH, PP, or PV or across pre- and post-test trials.
These preliminary findings suggest that standard treatment times of IASTM do not produce an immediate effect in muscular performance in healthy participants. This may help clinicians determine the optimal sequencing of IASTM when it is part of a pre-performance warm-up program. Future research should be conducted to determine the muscle performance effects of IASTM in individuals with known myofascial restriction and to determine optimal treatment parameters, such as instrument type, amount of pressure, and treatment time necessary to affect muscular performance.

器械辅助软组织松动术（IASTM）是一种非侵入性治疗技术，理论上有助于瘢痕组织的分解与吸收、筋膜松动以及促进组织愈合。研究人员推测，使用IASTM将提高肌肉效率和表现；然而，以往的研究主要集中在治疗损伤方面。
本研究旨在探讨IASTM对肌肉表现的影响，以评估典型的治疗应用是否会影响肌肉表现的测量指标。
一项前后测随机对照设计。
选取48名身体活跃的成年人（平均年龄24±4岁）作为便利样本，随机分为三组：股四头肌治疗组、小腿三头肌治疗组或对照组。
参与者在Monark自行车测力计上进行5分钟热身，然后进行三次反向运动垂直跳（CMJ）。之后，对于分配到治疗组的参与者，由一名研究人员在指定部位（如股四头肌）对每条腿进行3分钟的IASTM治疗，而对照组休息6分钟。治疗后立即让参与者再进行三次CMJ。前后测包括垂直跳高度（JH）、峰值功率（PP）和峰值速度（PV）的测量。
治疗组之间在JH、PP或PV方面，以及前后测试验之间均未发现统计学上的显著差异。
这些初步研究结果表明，IASTM的标准治疗时间对健康参与者的肌肉表现没有立即产生影响。这可能有助于临床医生在IASTM作为运动前热身计划的一部分时确定其最佳顺序。未来应开展研究，以确定IASTM对已知肌筋膜受限个体的肌肉表现影响，并确定最佳治疗参数，如器械类型、压力大小以及影响肌肉表现所需的治疗时间。
