Postural sway assessment.

FO–standing on firm surface, eyes open; FC–standing on firm surface, eyes closed; CO–standing on complian surface, eyes open; CC–standing on compliant surface, eyes closed; NP–no pain; PPGP–pregnancy related pelvic girdle pain; SD–standard deviation; p–p value; p 2NP– 3NP–p value between second trimester no pain group and third trimester no pain group; ML–medio lateral; AP–antero posterior; * indicates a significant difference.

The comparison of mean velocity (A), sway area (B), medio-lateral path length (C) and antero-posterior path length (D) for the effect of trimester of pregnancy and for the effect of PPGP. FO–standing on firm surface with eyes open; FC–standing on firm surface with eyes closed; CO–standing on compliant surface with eyes open; CC–standing on compliant surface with eyes closed; 2NP–second trimester, no-pain group (white); 2PPGP–second-trimester pregnancy-related pelvic girdle pain group (orange); 3NP–third-trimester no-pain group (blue); 3PPGP–third-trimester pregnancy-related pelvic girdle pain group (yellow); * indicates a significant difference between the two groups p<0,05.</p
