Comparison of difference values in seat-interface pressure. Seat-interface pressure between left and right buttock measured from the three steps: on initial seated, on balancing seated, and on 1 h balancing seated. The average pressure difference value was 36.4 ± 32.3 Ω for initial seating, 15.7 ± 20.3 Ω on subsequent balanced seating, and 12.7 ± 10.9 Ω on 1 h balancing seated, demonstrating statistically significant improvements among the steps (P = .003, .008, ANOVA).
