The results substantiate that a balance training program was effective in significantly reducing the rate of recurrent ankle sprains in those high school athletes who had prior ankle sprains. This result is in accord with the results of prior studies. Verhagen et al,26 who studied the effect that a 36-week balance board training program had on reducing ankle sprains in adult Dutch volleyball players, found that the number of self-reported ankle sprains was significantly lower in athletes completing the intervention program. This result, however, was seen only in players with a history of an ankle sprain.
