Abstract:

Objective To explore the posture control of professional dancers.
Methods From April to August, 2017, 21 professional dancers from an international famous club were as experimental group. Matching the height and age, etc., 21 medical workers were recruited as control group. They were tested with Tetrax Balance Evaluation System, and assessed with Trunk Stability Test (TST) and the Star Excursion Balance Test (SEBT).
Results There was no significant difference on fail-time of TST and maximum distance of SEBT between right and left sides in both groups. The fail-time of TST was less in the experimental group than in the control group (t = -2.667, P < 0.05), as well as the maximum distance of SEBT ( t = -3.991, P < 0.001). There was no significant difference on falling index between both groups ( t = 1.810, P > 0.05).
Conclusion Compared with medical workers, professional dancers do better in static balance, but worse in dynamic balance. Their performance of posture control is almost the same as the others.
