As a follow-up to this long-dormant thread, I noted that the January 2010
Journal of Family Practice included an article that, based on the results of the clinical trial that I mentioned above, recommends that physicians direct their patients who have suffered ankle sprains to follow a program of ankle training (such as a wobble board program) at home following appropriate treatment.
Help patients prevent repeat ankle injury — The Journal of Family Practice
The article includes this information:
In many sports, ankle sprain is the most common injury, partly because an athlete who incurs a first ankle sprain is at increased risk of another. The risk of reinjury is highest in the year immediately following the initial sprain. About half of recurrent ankle sprains result in chronic pain or disability, so preventing repeat sprains is an important patient-oriented treatment goal.
