1. The document discusses a methodology for using high-frequency current (HCR) and Synergy Mats to treat lateral ankle ligament sprains. 2. HCR is applied at different intensities and locations over time to stimulate microcirculation, reduce edema, enhance vasodilation, and increase internal tissue temperature during the acute, inflammatory, and remodeling phases of healing. 3. Synergy Mats with different surfaces are used for proprioceptive rehabilitation exercises to reactivate the neuromuscular system and prevent future sprains. The document also notes that recovery time is needed after exertion to allow regeneration of joints, muscles and tendons.
