[Training on a wobble board following lateral ankle joint sprains].

The aim of this study was to investigate whether the number of patients with residual symptoms following ankle sprains could be reduced by training on a wobble board during a 12-week training recovery period. The effect of a 12-week training program was compared to no training. Forty-eight patients completed the study. In the follow-up period (mean 230 days) we found significantly fewer recurrent distorsions and fewer patients had functional instability in the study group compared to controls. There were no differences between the two groups concerning subjective complaints during the recovery period. Volumetric measurements revealed no difference in the speed of reduction of haematoma and oedema in the two groups. We conclude that training on a wobble board is effective in reducing residual symptoms following ankle sprains.
