Adolescent DanceSport athletes who regularly dance in high heels have a higher possibility of developing hallux valgus deformity and foot pain. We believe that the occurrence of foot disorders may change the loading on their feet, which thus affects the athletic performance of those adolescents.
A total of 63 adolescent DanceSport athletes (16 boys, 47 girls) were included. The plantar pain in the first metatarsophalangeal (1st MTP) joint was evaluated using a questionnaire, and the hallux valgus angle was evaluated using digital photographs (HVAp). The loading values of the plantar pressure while performing relève on demi-pointe were measured using sensor sheets. The participating boys and girls were analyzed separately.
The results showed that female adolescent DanceSport athletes with the 1st MTP joint plantar pain showed a decrease in the loading distribution and plantar pressure percentage on the hallux and an increased loading distribution and pressure distribution of the metatarsal head as the HVAp increased.
Among adolescent DanceSport athletes with plantar pain in the 1st MTP joint and a large HVAp, the loading manner of the foot may have changed, which may be associated with a decrease in the toe function and performance.
经常穿着高跟鞋跳舞的青少年体育舞蹈运动员发生拇外翻畸形和足部疼痛的可能性更高。我们认为足部疾病的发生可能会改变他们足部的负荷，从而影响这些青少年的运动表现。
共纳入63名青少年体育舞蹈运动员（16名男孩，47名女孩）。使用问卷评估第一跖趾关节（第1 MTP）的足底疼痛，并使用数码照片评估拇外翻角度（HVAp）。使用传感片测量在半脚尖上做立踵动作时的足底压力负荷值。对参与的男孩和女孩分别进行分析。
结果表明，第1 MTP关节足底疼痛的女性青少年体育舞蹈运动员随着HVAp增加，拇趾上的负荷分布和足底压力百分比降低，跖骨头的负荷分布和压力分布增加。
在第1 MTP关节有足底疼痛且HVAp较大的青少年体育舞蹈运动员中，足部的负荷方式可能已经改变，这可能与脚趾功能和表现的下降有关。
