Assisi LOOP therapy treats a wide range of inflammatory issues, including Post-surgical recovery, Wound healing, Spinal and nerve disorders, Internal inflammation, pancreatitis, and Issues related to aging, such as osteoarthritis and bone and joint injuries. Assisi LOOP provides safe and effective management of pain and inflammation at home or on the go. Assisi LOOP is a medical device that emits a targeted, pulsed electromagnetic field designed to reduce inflammation, decrease pain, and enhance healing in soft tissue and bone. The electromagnetic pulses penetrate through wraps, dressings, and casts. This size is appropriate for conditions that cover a smaller body area. How to Use the Assisi LOOP - Place the center of the loop over the area that needs treatment as directed by your veterinarian. Press the on-off button once. Both green lights will flash on the front of the signal generator, indicating treatment is being delivered. Treat for 15 minutes. The Assisi LOOP will automatically turn off after the 15-minute treatment has been delivered. More frequent use could reduce battery life substantially. The battery in this item cannot be recharged or replaced. Ask your veterinarian which size and version is right for your pet.
