In 20 female performers of classical ballet the range of dorsiflexion of the big toe was found to be significantly decreased. However, in only one case was the decrease sufficiently great to interfere with the dancer's ability to perform. In spite of the severe stress put on the first metatarso-phalangeal joint in dancers the resulting degenerative changes were found to be minor and in most instances without clinical consequences. The results indicate that professional ballet, contrary to what is believed, rarely has harmful effects on the first metatarso-phalangeal joint.
在20名古典芭蕾舞女表演者中，发现大脚趾背屈范围显著减小。然而，只有一例减小幅度足够大，影响了舞者的表演能力。尽管舞者的第一跖趾关节承受着巨大压力，但由此产生的退行性变化较小，在大多数情况下没有临床症状。结果表明，与人们的看法相反，专业芭蕾舞对第一跖趾关节很少有有害影响。
