既往有胫骨内侧应力综合征（MTSS）病史是 MTSS 复发的危险因素，这表明有 MTSS 病史的跑步者可能存在一些与 MTSS 发展相关的身体因素。 MTSS 和肌肉僵硬之间的关系可以通过一项横断面研究来评估，该研究测量有 MTSS 病史、测量时没有疼痛的受试者和没有 MTSS 病史的受试者的肌肉僵硬。本研究的目的是比较有 MTSS 病史和无 MTSS 病史的受试者的所有小腿后部肌肉的剪切弹性模量（肌肉僵硬的指标），并调查哪些肌肉可能与 MTSS 相关。 24名男性大学生跑步运动员（年龄，20.0+/-1.7岁；身高，172.7+/-4.8cm；体重，57.3+/-3.7kg）参与了本研究； 14 人有 MTSS 病史，10 人没有。使用剪切波弹性成像测量腓肠肌外侧肌、腓肠肌内侧肌、比目鱼肌、腓骨长肌、腓骨短肌、拇长屈肌、趾长屈肌和胫骨后肌的剪切弹性模量。有 MTSS 病史的受试者的趾长屈肌和胫骨后肌的剪切弹性模量显着高于无 MTSS 病史的受试者。然而，其他肌肉的剪切弹性模量没有显着差异。这项研究的结果表明，趾长屈肌和胫骨后肌僵硬可能与 MTSS 相关。
Previous history of medial tibial stress syndrome (MTSS) is a risk factor for MTSS relapse, which suggests that there might be some physical factors that are related to MTSS development in runners with a history of MTSS. The relationship between MTSS and muscle stiffness can be assessed in a cross-sectional study that measures muscle stiffness in subjects with a history of MTSS, who do not have pain at the time of measurement, and in those without a history of MTSS. The purpose of this study was to compare the shear elastic modulus, which is an index of muscle stiffness, of all posterior lower leg muscles of subjects with a history of MTSS and those with no history and investigate which muscles could be related to MTSS. Twenty-four male collegiate runners (age, 20.0 +/- 1.7years; height, 172.7 +/- 4.8cm; weight, 57.3 +/- 3.7kg) participated in this study; 14 had a history of MTSS, and 10 did not. The shear elastic moduli of the lateral gastrocnemius, medial gastrocnemius, soleus, peroneus longus, peroneus brevis, flexor hallucis longus, flexor digitorum longus, and tibialis posterior were measured using shear wave elastography. The shear elastic moduli of the flexor digitorum longus and tibialis posterior were significantly higher in subjects with a history of MTSS than in those with no history. However, there was no significant difference in the shear elastic moduli of other muscles. The results of this study suggest that flexor digitorum longus and tibialis posterior stiffness could be related to MTSS.
