Functional hallux limitus is defined as a functional inability of the proximal phalanx of the hallux to extend on the first metatarsal head during gait. The theory concerning this anomaly and the altered gait characteristics that may result appears to have influenced the understanding of sagittal plane podiatric biomechanics. Although there is an increase in the body of evidence to support the proposed gait alterations, a detailed review suggests the need for further work. The aim of this article is to review the functional hallux limitus literature and its reported effects on gait. Furthermore, we explore some of the key and inherent problems with obtaining accurate data for joint motion measurement in the foot. With evidence-based practice now at the forefront of both clinical and academic practice, it is imperative to review the literature that underpins a particular commonly held or historical belief, in order to substantiate and validate subsequent diagnoses and treatments provided in light of this information. This is also true to advance the understanding of a particular anomaly or pathology and to inform so as to facilitate the provision of better care to patients.
功能性拇趾僵硬被定义为在步态过程中，拇趾近节趾骨无法在第一跖骨头处伸展的一种功能障碍。关于这种异常情况以及可能导致的步态特征改变的理论，似乎已经影响了对矢状面足病生物力学的理解。尽管有越来越多的证据支持所提出的步态改变，但一项详细的综述表明仍需进一步研究。本文的目的是回顾功能性拇趾僵硬的相关文献及其对步态的影响。此外，我们探讨了在获取足部关节运动测量准确数据方面的一些关键和固有问题。鉴于循证实践如今在临床和学术实践中都处于前沿位置，有必要回顾支撑某种特定的普遍认知或历史观点的文献，以便根据这些信息证实并验证后续的诊断和治疗方法。这对于增进对特定异常情况或病理状况的理解以及为更好地为患者提供护理提供参考也是如此。
