Changes in tissue stiffness are associated with pathological conditions such as myofascial pain and increased risk of muscle injury. Furthermore, they have been shown to modify performance indicators such as running economy or jump height. Indentometry is an affordable way to assess tissue stiffness. However, to date, there is a paucity of studies examining the measurement properties of available devices. With this trial, we aimed to evaluate the reliability of the “IndentoPro”. Two investigators repeatedly measured the stiffness of the lateral head of the gastrocnemius muscle in healthy participants (N = 35), using 5 and 10 mm indentation depths. Intraclass Correlation Coefficients (ICC) revealed moderate inter-rater reliability (5 mm: ICC3,1 0.74, 95%CI = 0.54 to 0.86, p < 0.001; 10 mm: ICC3,1 0.59, 95%CI = 0.27 to 0.78, p < 0.001) and good intra-rater reliability (5 mm: ICC3,1 0.84, 95%CI = 0.71 to 0.92, p < 0.001; 10 mm: ICC3,1 0.83, 95%CI = 0.69 to 0.91, p < 0.001). No correlations between age, height, weight, BMI, skinfold thickness and myofascial tissue stiffness were observed (p > 0.5). In conclusion, the IndentoPro is reliable in assessing calf tissue stiffness, but the predictors of stiffness remain unclear.
组织硬度的变化与诸如肌筋膜疼痛和肌肉损伤风险增加等病理状况相关。此外，它们已被证明会改变诸如跑步经济性或跳跃高度等性能指标。压痕测量法是评估组织硬度的一种经济实惠的方法。然而，迄今为止，研究现有设备测量特性的研究很少。通过本试验，我们旨在评估“IndentoPro”的可靠性。两名研究人员使用5毫米和10毫米的压痕深度，对35名健康参与者的腓肠肌外侧头的硬度进行了重复测量。组内相关系数（ICC）显示评分者间信度中等（5毫米：ICC3,1 0.74，95%CI = 0.54至0.86，p < 0.001；10毫米：ICC3,1 0.59，95%CI = 0.27至0.78，p < 0.001），评分者内信度良好（5毫米：ICC3,1 0.84，95%CI = 0.71至0.92，p < 0.001；10毫米：ICC3,1 0.83，95%CI = 0.69至0.91，p < 0.001）。未观察到年龄、身高、体重、BMI、皮褶厚度与肌筋膜组织硬度之间的相关性（p > 0.5）。总之，IndentoPro在评估小腿组织硬度方面是可靠的，但硬度的预测因素仍不清楚。
