摘要:Purpose. The aim of this study was to compare the joint position sense (JPS) between professional ballet dancers and non-dancers controls. Methods. The study group consisted of thirty six professional ballet dancers and gender-matched controls. Measurements were performed on each group after filling out a questionnaire about their dance and injury backgrounds. Left and right arm flexion 50º and abduction 50º and left and right leg flexion 55º and abduction 70º were selected as measurement movements from dancers’ routine practice. Subjects repeated each movement six times with five-second intervals. Acumar Digital Inclinometer was used for JPS measurements and Gollehon Extendable Goniometer was used for validating the accuracy of measurements. The outcome measurement was an error score calculated as the mean absolute deviation (MAD) between the target and replicated angle. Results. JPS was significantly better in the dancer group compared to the control group. JPS did not show a significant difference between males and females. It was found no correlation between dance year and MAD values, except for the left hip abduction MAD levels (p≤0.05). No significant difference was found between the right and left extremities. In comparing the upper and lower extremities, there was no significant difference except for the comparison of right shoulder and right hip flexion. Conclusion. Professional ballet dancers demonstrated greater accuracy in joint position. “Continued and repeated practice” may improve proprioceptive responses of dancers.
