Correlation between stabilometric parameters and the time since surgery (eyes opened (EO) and eyes closed (EC)).
| | Stabilometric parameters | Time since surgery [months] |
| | EC/EO ratio | | COP path length (cm) | 0,02 (p = 0,898) | | COP path area (cm2) | 0,11 (p = 0,439) |
| | Eyes opened (EO) | | COP deviation mean velocity (AP) (cm/s) | −0,30 (p = 0,026) | | COP deviation mean velocity (ML) (cm/s) | −0,29 (p = 0,031) | | COP path length (cm) | −0,29 (p = 0,029) | | COP path area (cm2) | −0,24 (p = 0,079) |
| | Eyes closed (EC) | | COP deviation mean velocity (AP) (cm/s) | −0,27 (p = 0,048) | | COP deviation mean velocity (ML) (cm/s) | −0,22 (p = 0,102) | | COP path length (cm) | −0,26 (p = 0,059) | | COP path area (cm2) | −0,16 (p = 0,230) |
