Intrinsic Factors Analyzed in Athletes Without Previous Ankle Spraina
| Variable | Control Group (n = 40) | Injury Group (n = 4) | P Value |
|---|---|---|---|
| Mass, kg | 68.3 ± 10.0 | 73.2 ± 6.1 | .175 |
| Height, cm | 171.5 ± 7.6 | 175.3 ± 3.4 | .122 |
| Dorsiflexion ROM, deg | 43.7 ± 6.3 | 42.0 ± 8.8 | .961 |
| LHA prone, deg | –5.8 ± 2.6 | –4.3 ± 1.0 | .368 |
| LHA standing, deg | 3.0 ± 1.6 | 2.5 ± 1.7 | .408 |
| Foot internal rotation angle, deg | 8.4 ± 3.4 | 6.0 ± 2.4 | .199 |
| Mortise test, positive % | 86.3 | 75.0 | .611 |
| NMM distance, cm | 3.8 ± 0.7 | 4.7 ± 0.5b | .025 |
aData are presented as mean ± standard deviation. The control group included athletes who suffered no ankle sprain during the study period; the injury group included athletes who suffered lateral ankle sprain. LHA, leg-heel angle; NMM distance, navicular–medial malleolus distance; ROM, range of motion.
