Data are expressed as means±SD. Condition 1: eyes open, fixed visual surround and fixed support platform; condition 2: eyes closed, fixed support platform; condition 3: eyes open, mobile visual surround (moving proportional to the angle of anterior-posterior body sway) and the fixed support platform; condition 4: eyes open, fixed visual surround and mobile support platform (moving proportional to the angle of anterior-posterior body sway); condition 5: eyes closed, mobile support platform and condition 6: eyes open, mobile visual surround and mobile support platform.
↵*Statistically significant differences between patients and controls (p<0.001; ANCOVA test).
↵†Statistically significant differences between conditions 1–3 (p<0.01; ANCOVA test).
ANCOVA, analysis of covariance; FM, fibromyalgia; SOT, sensory organisation test.
