Ultrasound therapy devices use sound waves to promote healing in tissues. They generate high-frequency sound waves that penetrate the skin, creating heat and increasing blood flow to the targeted area. This can help reduce pain, swelling, and stiffness, making it beneficial for conditions like arthritis or muscle injuries. These devices are commonly used in physical therapy settings. A trained therapist applies a gel to the skin and moves the ultrasound wand over the affected area. The treatment is non-invasive and typically lasts about 5 to 10 minutes, providing a safe option for pain relief and tissue repair.
