Purpose: To investigate the effects of single-leg stance on a textured balance board on activity of lower extremity muscles and postural control. Design: Cross-sectional study. Setting: University’s laboratory. Participants: Twenty-six healthy adults (12 females, 14 males; mean age = 25.4 years). Methods: Participants were asked to balance in single-leg stance on the floor, a textured balance-board and a smooth balance board. Electromyographic activity (EMG) of eight leg muscles and center of pressure (COP) displacements were measured. Friedman tests (p<0.05) and post hoc Wilcoxon-signed rank tests (p<0.05) with Bonferroni correction were used to determine significance of differences between conditions. Results: Neither EMG-activities, nor COP-displacements differed significantly between the textured and the smooth balance board (p>0.05). Significantly higher muscle activities and COP displacements (p<0.05) were observed using the balance boards compared to the floor. Conclusions: Single-leg stance using a textured balance board seems not to lead to increased activation of lower extremity muscles and COP displacements compared to a smooth balance board.
