To confirm the efficacy of hyperbaric oxygen therapy in acute ankle sprain. This study was conducted at Princess Haya Al-Hussein Hospital's Hyperbaric chamber/Aqaba-Jordan, on 36 patients, treated in the Emergency Department. They had been divided according to the type of treatment into A, B and C. Group A had been treated at one absolute atmospheric pressure [1 ATA], group B at 2 ATA, and group C at 2.5 ATA. All groups received seven hyperbaric sessions, as outpatients in 5 consecutive days, twice a day for two days followed by once a day for the remaining three days, for a 90 minute-session. All patients with acute ankle sprain with no history of recurrent attacks, had been treated at 2.5 ATA [gtoup C] were completely free of pain and of swelling by the end of the last session. Hyperbaric oxygen therapy is the best choice for the rapid recovery of acute ankle sprain
