Postural stability is an important component of skilled athletic activity. However, the effects of foot orthoses on stability have not been adequately addressed. This study measured postural sway in 30 asymptomatic professional soccer players in three standing positions and four underfoot conditions. The results revealed that the underfoot condition had no significant effect on sway in the mediolateral or anteroposterior planes; however, there was a trend toward less mediolateral sway when subjects stood in a unipedal position with prefabricated orthoses. These results suggest that insoles and foot orthoses have no significant beneficial or detrimental effects on postural stability in asymptomatic subjects. Clinically, this suggests that no improvements in balance performance could be expected with prophylactic use of insoles or orthoses but that clinicians may prescribe insoles and foot orthoses without fear of impairing postural performance in elite athletes.
姿势稳定性是熟练的体育活动的一个重要组成部分。然而，足部矫形器对稳定性的影响尚未得到充分研究。本研究测量了30名无症状职业足球运动员在三种站立姿势和四种足底条件下的姿势摆动。结果显示，足底条件对内外侧或前后平面的摆动没有显著影响；然而，当受试者穿着预制矫形器单脚站立时，内外侧摆动有减少的趋势。这些结果表明，鞋垫和足部矫形器对无症状受试者的姿势稳定性没有显著的有益或有害影响。临床上，这表明预防性使用鞋垫或矫形器不会改善平衡能力，但临床医生可以为精英运动员开具鞋垫和足部矫形器，而不用担心会损害其姿势表现。
