背景：足部固有肌肉功能障碍和足弓不良与各种足部疾病有关。屈趾肌锻炼(TFE)已经被用来改善它；然而，TFE对每种IFM的直接影响以及它与舟骨高度(NH)的变化之间的关系尚不清楚。目的：本研究旨在探讨TFE术后IFM的急性肌肉肿胀以及NH的变化与IFM大小的关系。方法：14名成人参与本研究。分别于TFE前、后测NH和IFM横截面积(CSA)。超声测量拇外展肌、拇短屈肌、趾短屈肌和掌方肌的CsA。在TFE中，每个参与者都以最大的力量完成了五组八次重复。结果：所有IFM患者TFE后NH和CsA均显著升高(p<；0.01)。仅ABH升高与NH变化呈中度正相关(r=0.54，p<；0.01)。结论：本研究提示TFE术后ABH的急性肿胀与NH的即刻升高有关，支持了ABH在足弓形成中的重要作用。
BACKGROUND: Intrinsic foot muscle (IFM) dysfunction and poor foot arch are associated with various foot conditions. Toe flexor exercise (TFE) has been used to improve it; however, the immediate effects of TFE on each IFM and how it relates to changes in navicular bone height (NH) are unclear. OBJECTIVE: This study aimed to investigate acute muscle swelling in the IFM after TFE and the association between changes in NH and IFM size. METHODS: Fourteen adults participated in this study. NH and cross-sectional area (CSA) of the IFM were acquired pre and post- TFE. The CSA of the IFM, including the abductor hallucis (AbH), flexor hallucis brevis, flexor digitorum brevis, and quadratus plantae, was acquired with ultrasonography. In the TFE, each participant completed five sets of eight repetitions with maximum strength. RESULTS: The NH and CSA of all IFM significantly increased significantly post-TFE (p< 0.01). Only the increase in AbH was moderately and positively correlated with the change in NH (r= 0.54, p< 0.01). CONCLUSION: This study suggests that the acute swelling of AbH after TFE is associated with an immediate increase in NH, supporting the important role of AbH in the formation of foot arch.
