We studied prospectively the influence of ankle sprains on proprioception as measured by recording the postural sway of classical ballet dancers. Excellent balance and coordination are important for classical ballet dancers, and postural stability requires adequate proprioception from the ankle joint. Fifty-three professional dancers from the Royal Swedish Ballet, Stockholm, and 23 nonathletes, the control group, participated in the investigation. Postural sway was recorded and analyzed with a stabilimeter using a specially designed, portable, computer-assisted force plate. Six dancers sustained ankle sprains during followup. The recordings were obtained of these dancers before and after the injuries. The stabilometry results differed among the male and female dancers and the control group as follows: 1) the male dancers demonstrated a smaller total area of sway, and 2) both the male and female dancers had a smaller mean sway on the left foot than on the right (no mean difference in sway was found between the left and right foot in the control group). In comparison with the condition before injury and with the uninjured foot, the postural stability of the dancer was impaired for several weeks after the ankle sprain. Postural stability gradually improved during rehabilitation and improvement still occurred several weeks after professional dancing had resumed.
我们通过记录古典芭蕾舞演员的姿势摇摆来前瞻性地研究踝关节扭伤对本体感觉的影响。出色的平衡和协调能力对古典芭蕾舞演员很重要，而姿势稳定性需要踝关节具备足够的本体感觉。来自斯德哥尔摩瑞典皇家芭蕾舞团的53名职业舞者和23名非运动员（对照组）参与了这项调查。使用专门设计的便携式计算机辅助测力板，通过稳定仪记录并分析姿势摇摆情况。在随访期间，有6名舞者发生了踝关节扭伤。记录了这些舞者受伤前后的情况。稳定测量结果在男女舞者和对照组之间的差异如下：1）男性舞者的总摇摆面积较小；2）男性和女性舞者左脚的平均摇摆幅度均小于右脚（对照组左右脚的摇摆幅度无平均差异）。与受伤前的情况以及未受伤的脚相比，踝关节扭伤后，舞者的姿势稳定性受损了数周。在康复过程中，姿势稳定性逐渐改善，并且在恢复专业舞蹈训练数周后仍有改善。
