The aim of this study was to evaluate the influence of upper-leg muscle fatigue on knee joint proprioception in 13 ballet dancers and 13 non-dancer controls. Proprioception acuity, expressed as position and motion sense, was measured with an isokinetic dynamometer. The position and motion sense assessments were prior to and immediately after an isokinetic upper-leg muscle fatigue protocol. Participants wore blindfolds for both tasks to eliminate vision, an inflated air splint on their lower leg to neutralize cutaneous sensation, and headphones with white noise during the motion sense task to eliminate auditory cues. Results showed no significant differences in position and motion sense between dancers and controls in the non-fatigued state. In the fatigued state no significant differences were found in position sense between dancers and controls, while controls increased significantly in motion sense error (p = 0.030) and ballet dancers showed no change in motion sense. It is concluded that position sense and motion sense acuity are not affected by muscle fatigue in dancers, but motion sense is affected by muscle fatigue in non-dancers.
本研究旨在评估13名芭蕾舞舞者和13名非舞者对照中，大腿肌肉疲劳对膝关节本体感觉的影响。采用等速测力计测量以位置觉和运动觉表示的本体感觉敏锐度。位置觉和运动觉评估在等速大腿肌肉疲劳方案实施之前和之后立即进行。两项任务中参与者均佩戴眼罩以消除视觉，小腿上佩戴充气夹板以中和皮肤感觉，运动觉任务期间佩戴带有白噪音的耳机以消除听觉线索。结果显示，在非疲劳状态下，舞者和对照之间的位置觉和运动觉无显著差异。在疲劳状态下，舞者和对照之间的位置觉无显著差异，而对照的运动觉误差显著增加（p = 0.030），芭蕾舞舞者的运动觉无变化。结论是，舞者的位置觉和运动觉敏锐度不受肌肉疲劳影响，但非舞者的运动觉受肌肉疲劳影响。
