Abstract des Autors
We performed this study to monitor changes in ankle eversion strength and sensorimotor control functions after acute ankle inversion injury. Forty-four patients with clinical grade II to III first-time ankle inversion sprains were tested for 1) pathologic talar tilt and anterior talar translation at 1 and 12 weeks after injury; 2) isometric eccentric ankle eversion strength and 3) peroneal reaction time to sudden ankle inversion at 3, 6, and 12 weeks after injury; and 4) accuracy of inversion position assessment 1, 3, 6, and 12 weeks after injury. Not all patients could perform all tests at the early follow-up visits. There was mechanical instability in 19 of 40 tested patients at 1 week and in 4 patients at 12 weeks after injury. Eversion strength was 88% of the contralateral side 3 weeks after injury, rising to 96% after 12 weeks. The magnitude of error of inversion position sense was 190% of the contralateral side 1 week after injury; this was still affected after 12 weeks, but fell to 133%. Patients with pathologic talar tilt or anterior talar translation, or both, at 1 week after injury did not show significantly greater error in position assessment or reduction in eversion strength when compared with patients with ankles that remained stable after injury.
