Balance abilities of professional dancers on select balance tests.
Documentation that dancers have better balance abilities than nondancers is important because of the number of dancers who sustain injury and then are referred to physical therapists for treatment. The purpose of this study was to compare balance abilities of professional dancers with nondancers on selected balance conditions. Fifteen dancers and 15 age- and gender-matched nondancers maintained one-legged stance under six combinations of visual and support surface conditions (Foam and Dome Test modified from two feet to one foot). Each condition was maintained for 30 seconds. A composite balance score was obtained for each subject by summing the number of seconds the individual maintained balance for each test condition. There was a significant difference in the mean composite balance score (across the six balance conditions) for the dance group compared with the control group (731 seconds and 563 seconds, respectively). Under sensory challenged conditions, it appeared that dancers were better able to maintain their postures upright against gravity. The balance strategies and techniques learned by professional dancers should be carefully analyzed to determine if they could be incorporated into treatment programs for nondancers who have balance instability and dancers who are injured.
