Objective roentgenologic measurements of the influence of ankle braces on pathologic joint mobility. A comparison of 9 braces.
The stabilizing effect of external support (taping and nine different ankle braces) was tested in a total of 220 functionally unstable ankles. A standard surface EMG controlled stress Roentgen test protocol was used, measuring talar tilt (TT) without support and with tape bandage or brace. Different levels of TT restraining by external support could be identified. Tape bandage and two braces had a highly significant influence on the talar tilt. The mean TT without support was decreased by using from 13.4 degrees to 4.9 degrees, by using one brace to 4.8 degrees and by using another brace to 5.9 degrees. These two braces are effective for protection during functional treatment. A classification into three grades of effectiveness is proposed. It is concluded that the stabilizing influence offered by bandages and braces should be measured before using the external support as a treatment device for acute ankle sprain and as a reliable protection against sprain injuries in daily living and sports.
