Effect of Sustained Acoustic Medicine on Bruising Following A Bicycle Crash

In late September, 2020 a man was riding his mountain bike on a trail. Half-way into his ride his bike flipped and he fell off. His hip hit a rock. On examination 1 hour later he noticed a severe bruise on his hip. He immediately applied RICES for the next 2 days, except when he was sleeping. His on-off ratio for the RICES was 90-min "on", 90 "min" off. Two days later he quit using RICES. Three days later he used sustained acoustic ultrasound (SAM) a small, portable ultrasound that can be used for up to 4hrs. Photos were taken after the 3^rd and 6^th treatment. There was lots of flesh colored tissue on the skin where the leg was treated with SAM.
