| PI | 61 (67.8–53.8) | 44 (54–35) | < 0.05 |
| LL | 39 (46.5–24.3) | 49 (58.5–41) | < 0.05 |
| PI-LL | 21 (26.8–13) | -2 (5–14) | < 0.05 |

| MPTA | 85 (87–76.5) | 87 (89–86) | < 0.05 |
The comparison was carried out by independent sample non-parametric test. Significant difference in PFP was revealed between the two subgroups of subjects
