The purpose of this study was to illustrate the use for the A.E.R. Boot in the treatment of acute ankle sprains. Pain, edema, girth, and range of motion measurements were used to assess the effectiveness of the boot. Two subjects who sustained inversion ankle sprains followed a treatment protocol utilizing the A.E.R. Boot for five consecutive days. Each subject was evaluated pre- and post-treatment on day one and post-treatment on day five. Evaluation methods included: a 10-centimeter visual analogue scale to assess pain, water volumetry to measure ankle volume, figure-of-eight measurements to assess girth of the injured ankle, and goniometry to assess range of motion. Data from this study showed improvements in pain, volume and girth measurements from pretreatment day one to post-treatment day five. However, inconsistent results were obtained with range of motion measurements. Subject A showed an overall decrease in active range of motion, while subject B showed an overall increase in active range of motion. The results suggest that the A.E.R. Boot was effective in reducing pain and edema in acute ankle sprains. However, further research is needed with a larger sample size to derive statistical significance.
