Motion in the ankle, subtalar, midtarsal, and first metatarsophalangeal joints has been well documented. However, motion in the first metatarsocuneiform, the first cuneonavicular, and the first interphalangeal joint has not been addressed. Motion in these joints has not been documented because many believe that little motion occurs at these joints, and because of the difficulty in assessing motion at these joints. Using two-dimensional motion analysis, the authors present sagittal plane ranges of motion occurring in the first metatarsophalangeal joint, the first metatarsocuneiform joint, the medial cuneonavicular joint, and the first interphalangeal joint during the propulsive period of gait. This pilot study indicates that sagittal plane motion between the navicular and calcaneus and between the first metatarsal and first cuneiform are very mild and inconsistent. However, plantarflexion motion between the first cuneiform and the navicular is significant and comprises most of the plantarflexion motion of the first ray during propulsion. Motion in the first interphalangeal joint is slight during the first 80% of the propulsive period but shows slight-to-moderate dorsiflexion during the last 20% of the propulsive period of gait.
踝关节、距下关节、中跗关节和第一跖趾关节的运动已有充分记录。然而，第一跖楔关节、第一楔舟关节和第一趾间关节的运动尚未得到研究。这些关节的运动未被记录，是因为许多人认为这些关节几乎没有运动，也因为评估这些关节的运动存在困难。作者使用二维运动分析，展示了在步态推进期第一跖趾关节、第一跖楔关节、内侧楔舟关节和第一趾间关节矢状面的运动范围。这项初步研究表明，舟骨与跟骨之间以及第一跖骨与第一楔骨之间的矢状面运动非常轻微且不一致。然而，第一楔骨与舟骨之间的跖屈运动显著，且在推进过程中占第一跖列跖屈运动的大部分。在步态推进期的前80%，第一趾间关节的运动轻微，但在推进期的最后20%，该关节出现轻微至中度的背屈。
