【 摘 要 】

Category:Midfoot/ForefootIntroduction/Purpose:Range of motion measurements of the first metatarsophalangeal joint (MTPJ) are an essential component in assessing and classifying hallux rigidus (HR). However, they provide little information about joint function and are limited by variability in technique. As an alternative, measuring joint flexibility can characterize intrinsic properties of the joint—aside from simply maximum dorsiflexion and plantarflexion—that may prove more clinically meaningful. No prior study has assessed hallux MTPJ flexibility in patients with HR. The purpose of this study was therefore to assess the reliability of a custom flexibility device and to compare flexibility between HR patients and controls.Methods:Fifteen patients with Coughlin stage II or III HR indicated for cheilectomy and 20 healthy controls were recruited prospectively. Each of two raters performed a series of seated and standing tests on each subject with the device. Dorsiflexion angle and applied torque were plott...
