Intrinsic Factors Analyzed in Athletes With Previous Ankle Spraina
| Variable | Control Group (n = 113) | Injury Group (n = 12) | P Value |
|---|---|---|---|
| Mass, kg | 68.0 ± 9.2 | 62.8 ± 12.0 | .080 |
| Height, cm | 172.2 ± 7.0 | 169.1 ± 6.1 | .144 |
| Dorsiflexion ROM, deg | 42.3 ± 6.1 | 49.3 ± 9.3b | .000 |
| LHA prone, deg | −6.3 ± 2.7 | –6.8 ± 2.7 | .934 |
| LHA standing, deg | 3.2 ± 1.9 | 4.5 ± 1.9 | .207 |
| Foot internal rotation angle, deg | 9.3 ± 4.0 | 9.4 ± 5.3 | .640 |
| Mortise test, positive % | 72.3 | 58.3 | .547 |
| NMM distance, cm | 3.9 ± 0.7 | 3.5 ± 0.7 | .324 |
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.
