  		Fig. 1: Recruitment and allocation of schools and students to study groups. Subjects in the intervention group underwent a 6-week home-based proprioceptive balance-training program using a wobble board. All of the subjects underwent timed balance tests at baseline and at 2, 4 and 6 weeks. They were also asked to report sports-related injuries over the 6-month study period.
