目的:我们旨在探索,胫骨内侧应力综合征(MTSS)与胫骨内侧骨膜厚度和小腿肌肉僵硬度的相关性有关。
方法:这项研究包括63名受试者,分为3组:无症状组,MTSS组,和对照组。胫骨前肌(TA)的小腿肌肉僵硬度,趾长伸肌(EDL),腓骨长(PL),比目鱼(SOL),腓肠肌外侧(LG),腓肠肌内侧(MG),胫骨后肌(TP),通过二维剪切波弹性成像获得3组的趾长屈肌(FDL)。通过单向方差分析(ANOVA)和最小显着差异检验确定3组的肌肉硬度和胫骨内侧骨膜厚度的差异。使用Pearson相关性评估骨膜厚度与肌肉硬度之间的关系。
结果:无症状组和MTSS组除EDL外,所有小腿肌肉的剪切波速度(SWV)均高于对照组(TA,P=.001;PL,P=.006;SOL,P<.001;LG,P<.001;MG,P<.001;TP,P<.001;FDL,P=.013;和方差分析)。在SOL的SWV中发现了显着差异,TP,对照组和无症状组之间的FDL(分别为P=.041,P<.001和P=.013)。此外,跑步训练后胫骨内侧骨膜增厚,其厚度与肌肉僵硬度呈正相关。
结论:胫骨内侧骨膜厚度与小腿肌肉僵硬度呈正相关。SOL的变化,TP,和FDL刚度可能与MTSS的发生有关。
OBJECTIVE: We aimed to explore, which muscle stiffness changes may be related to medial tibial stress syndrome (MTSS) and the correlation between the medial tibial periosteal thickness and lower leg muscle stiffness.
METHODS: This study included 63 subjects distributed into 3 groups: the symptomless group, the MTSS group, and the control group. The lower leg muscle stiffness of the tibialis anterior (TA), extensor digitorum longus (EDL), peroneus longus (PL), soleus (SOL), lateral gastrocnemius (LG), medial gastrocnemius (MG), tibialis posterior (TP), and flexor digitorum longus (FDL) in the 3 groups was obtained by two-dimensional shear wave elastography. Differences in the muscle stiffness and medial tibial periosteal thickness in the 3 groups were determined by one-way analysis of variance (ANOVA) and least significant difference tests. The relationships between the periosteal thickness and the muscle stiffness were assessed using Pearson correlations.
RESULTS: The shear wave velocity (SWV) of all lower leg muscles except the EDL was higher in the symptomless and MTSS groups than in the control group (TA, P = .001; PL, P = .006; SOL, P < .001; LG, P < .001; MG, P < .001; TP, P < .001; FDL, P = .013; and ANOVA). A significant difference was found in the SWV of the SOL, TP, and FDL between the control and symptomless groups (P = .041, P < .001, and P = .013, respectively). Moreover, the medial tibial periosteum was thickened after running training, and its thickness was positively correlated with muscle stiffness.
CONCLUSIONS: The medial tibia periosteal thickness is positively correlated with the lower leg muscles stiffness. Changes in SOL, TP, and FDL stiffness may be related to the occurrence of MTSS.
