BACKGROUND
The use of foam rollers to provide tissue massage is a commonly used intervention by rehabilitation professionals for their patients and clients. Currently, there is no consensus on the optimal foam rolling treatment approach. Of particular interest are the effects of different instructional methods of foam rolling, as individuals ultimately perform these interventions independently outside of formal care. Finding the optimal instructional method may help improve the individual's understanding of the technique, allowing for a safe and effective intervention.
PURPOSE
The purpose of this study was to compare the effects of video-guided, live instructed, and self-guided foam roll interventions on knee flexion Range of Motion (ROM) and pressure pain thresholds.
METHODS
Forty-five healthy adults were recruited and randomly allocated to one of three intervention groups: video-guided, live-instructed, and self-guided. Each foam roll intervention lasted a total of 2 minutes. Dependent variables included knee flexion ROM and pressure pain threshold of the left quadriceps. Statistical analysis included subject demographic calculations and appropriate parametric and non-parametric tests to measure changes within and between intervention groups.
RESULTS
Each intervention group showed significant gains in knee flexion ROM (p ≤ 0.003) and pressure pain thresholds (p < 0.001). An approximate 5 degree increase of knee flexion and a 150 kPa increase in pressure pain threshold was observed at the posttest measure for all groups. There was no significant difference (p=0.25) found between intervention groups.
CONCLUSION
All three foam roll interventions showed short-term increases in knee flexion ROM and pressure pain thresholds. The two instructional methods (video and live instruction) and the self-guided method produced similar outcomes and can be used interchangeably. Individuals can benefit from various types of instruction and in cases of limited resources video may offer an alternative or adjunct to live instruction or an existing self-guided program.

背景
使用泡沫轴进行组织按摩是康复专业人员对患者常用的一种干预措施。目前，对于最佳的泡沫轴滚动治疗方法尚无共识。特别值得关注的是不同的泡沫轴滚动指导方法的效果，因为个人最终会在正规护理之外独立进行这些干预。找到最佳的指导方法可能有助于提高个人对该技术的理解，从而实现安全有效的干预。
目的
本研究的目的是比较视频指导、现场指导和自我指导的泡沫轴滚动干预对膝关节屈曲活动度（ROM）和压力痛阈的影响。
方法
招募了45名健康成年人，并将他们随机分配到三个干预组之一：视频指导组、现场指导组和自我指导组。每次泡沫轴滚动干预总共持续2分钟。因变量包括膝关节屈曲ROM和左股四头肌的压力痛阈。统计分析包括受试者人口统计学计算以及适当的参数和非参数检验，以测量干预组内部和之间的变化。
结果
每个干预组在膝关节屈曲ROM（p≤0.003）和压力痛阈（p<0.001）方面均有显著提高。在所有组的测试后测量中，观察到膝关节屈曲增加约5度，压力痛阈增加150 kPa。干预组之间未发现显著差异（p = 0.25）。
结论
所有三种泡沫轴滚动干预均显示膝关节屈曲ROM和压力痛阈短期内有所增加。两种指导方法（视频和现场指导）和自我指导方法产生了相似的结果，并且可以互换使用。个人可以从各种类型的指导中受益，在资源有限的情况下，视频可以作为现场指导或现有自我指导计划的替代或辅助手段。
