Common pediatric pathologic foot presentations include cavovarus and planovalgus feet. Flexibility of the hindfoot is established for these two clinical presentations through the Coleman block (eversion) and tiptoe tests (inversion).
The purposes of this study are to establish typical quantitative eversion and inversion motion of the hindfoot during Coleman block and tiptoe tests using 3-D motion capture and demonstrate feasibility of using this data to assist in making treatment decisions.
Segmented foot model kinematics were collected for this prospective descriptive study with a focus on coronal plane inversion and eversion of the hindfoot relative to the tibia. Typical standing hindfoot position, with the feet plantigrade, was determined prior to performing the tiptoe test. Maximum hindfoot inversion was extracted from the tiptoe test. Maximum hindfoot eversion was extracted from the Coleman block tests.
32 typically developing subjects (age range 5-21 years) completed this study. Hindfoot motion data showed a mean standing foot position of 1 ° eversion, 10 degrees inversion during tiptoe test and 6 degrees eversion during the Coleman block test.
Establishing control values for hindfoot flexibility can assist with making clinical treatment decisions for disorders of the foot. At our center, clients who present to the Motion Analysis Center with foot concerns receive segmented foot model quantitative assessment of hindfoot flexibility with Coleman block and tiptoe tests as appropriate.
小儿常见的足部病理表现包括高弓足和扁平足。通过 Coleman 木块（外翻）和足尖测试（内翻）可以确定这两种临床表现的后足灵活性。
本研究的目的是使用三维运动捕捉技术确定 Coleman 木块和足尖测试中后足的典型定量外翻和内翻运动，并证明使用该数据辅助治疗决策的可行性。
本前瞻性描述性研究采用分段足部模型运动学，重点研究后足相对于胫骨的冠状面内翻和外翻。在进行足尖测试之前，先确定典型的站立后足位置，使足部跖屈。从足尖测试中提取最大后足内翻，从 Coleman 木块测试中提取最大后足外翻。
32 名正常发育的受试者（年龄 5-21 岁）完成了本研究。后足运动数据显示，在站立位时足部的平均位置为 1°外翻，在足尖测试时为 10 度内翻，在 Coleman 木块测试时为 6 度外翻。
确定后足灵活性的控制值有助于为足部疾病的临床治疗决策提供依据。在我们的中心，有足部问题就诊运动分析中心的患者会接受分段足部模型的后足灵活性定量评估，包括 Coleman 木块和足尖测试。
