Postural stability of older female Scottish country dancers in comparison to physically active controls

Physical activity assists older individuals' functional ability and postural stability. Recently, Scottish country dance (SCD) was reported as being a beneficial form of physical activity for functional ability in older females. This study aims to examine the effect of SCD on postural stability. Scottish country dancers (n=20) were compared to physically active controls (n=33) for static postural sway measured on a force platform. The Romberg and Tandem stances were used, under 'eyes open' and 'eyes closed' conditions. 95% ellipse area and sway velocity were calculated from the center of pressure displacement. 95% ellipse area was the same for both groups in all tests. The control group had greater sway velocity for all tests (p<0.01) except Tandem eyes closed. SCD participation resulted in similar postural sway as participation in other physical activities, however non-dancers may need a greater amount of regulatory activity to maintain balance.
