Popis: The purpose of this study was to analyse objective modalities of ankle joint function after an acute ankle sprain and to see whether treatment with an air-cushioned ankle brace could enhance the restoration of function compared with a traditionally used compression bandage. The study included 73 consecutive patients between 15 and 55 years of age with an acute grade II or III ankle sprain, who sought medical care within 24 h of the time of injury. Patients with recurrent sprain were excluded. The patients were allocated at random to treatment with compression bandage or an air-cushioned ankle brace (Air-Stirrup, Aircast). The regimen included early motion and weight-bearing in both groups. The patients were examined initially within 24 h, after 3-5 days, 2, 4 and 10 weeks after the injury by the following tests: clinical examination including range of motion, recording of postural sway by stabilometry, joint position sense test, isokinetic eversion-inversion muscle torques and figure-of-eight running. A decreased active range of motion in eversion-inversion was observed during the entire follow-up period. Increased postural sway was registered when standing on the injured foot up to 4 weeks after the injury, as were a deficit in evertor muscle peak torque and an evertor-invertor muscle imbalance compared with the uninjured side. Women demonstrated a greater impairment in postural sway than men. A longer curve running time with the injured ankle at the outside of the curve was noted at the 10-week follow-up. With the exception of running in a figure of eight, these measures were not influenced by treatment with a semi-rigid ankle brace. The methods used in the present study are well suited for further studies of objective modalities of ankle joint function, with the possible exception of the joint position sense test.
