Lateral ankle sprains are common athletic injuries which lead to a decrease in balance via proprioceptive damage around the joint. Orthotics have been shown to help increase balance following acute ankle sprains. This research focused on the effect of orthotics on balance in participants with unilateral, subacute lateral ankle sprains and pes planus. Ten participants (half randomly assigned to orthotics group) performed balance testing twice (pre- and 5 minute-post) on each leg of the Biodex Balance System. A 2 X 2 ANOVA with Repeated Measures was used to evaluate the treatment (orthotics, no orthotics) over time (pre-orthotic, post-orthotic). The results revealed no treatment effects, interactions, or time effects for the dependant variables of overall stability index, anterior-posterior stability index, medial-lateral stability index for the injured and the uninjured ankles. In conclusion, for this time frame orthotics did not improve balance in participants with subacute lateral ankle sprains and pes planus.
