Purpose The purpose of this study was to compare postural stability between dancers and non-dancers with and without chronic ankle instability
Methods Twenty dancer and 20 non-dancer volunteered for this study. Dancers were divided to 2 sub-group (n=10/group); dancers with chronic ankle instability (D+CAI) and without CAI (D). While Non-dancers were divided into 2 sub-group (n=10/group); non-dancers with CAI (H+CAI) and without CAI (H). Overall Stability Index, anteroposterior stability index (APSI) and mediolateral stability index (MLSI) were measured using the Biodex balance system in 4 different conditions 1) single leg stance, composed of single leg stance with eyes opened on the floor (EO-Fl), 2) single leg stance with eyes closed on the floor (EC-Fl), 3) single leg stance with eyes opened on the foam (EO-Fo), and 4) single leg stance with eyes closed on the floor (EC-Fo). Two-way ANOVA was applied to determine the mean difference in OSI, APSI and MLSI in each group and each condition.
Results It was found that in EO-Fl condition, the H-group had lower OSI than that of the D+CAI group (p=0.04). The D-group had lower OSI than that of the H+CAI group (p=0.00). For APSI, D-group was significantly lower than the D+CAI group (p=0.01). The MLSI of H-CAI group was significantly lower than that of the H+CAI group (p=0.04). In EC-Fl condition, D-group presented lower OSI than that of the H+CAI group (p=0.02) and D+CAI group (p=0.00). In addition, H-group had lower APSI than that of the D+CAI group (p=0.01) and H+CAI group (p=0.05), as well as the D+CAI group (p=0.00). The MLSI of D-group was lower than that of the D+CAI group (p=0.03). For EC-Fo condition, OSI of D-group was lower than that of H+CAI group (p=0.00). The APSI of H-group was lower than that of H+CAI group (p=0.02). Moreover D-group had lower APSI than that of H+CAI group (p=0.00) D+CAI group (p=0.04, respectively.
Conclusion Dancers tend to have a better postural control than a healthy sedentary and dancers with CAI, and a healthy sedentary with CAI, respectively
