Elasto-Gel Shoulder Therapy provides ideal therapy for minor muscular and soft tissue shoulder-related injuries. Uniquely designed to give relief to the shoulder muscles of the upper arm, the upper chest, and the upper back. You can even perform arm exercises while wearing the wrap since it is totally flexible and held comfortably in place. Elasto-Gel Therapy Products are designed to provide moist heat therapy or soothing cold therapy for the relief of minor muscular and joint aches and pains. The hot or cold therapy will last 20 to 40 minutes per application. The product is held in place with hook and loop-type closures, which allow the user to move about during therapy. The product is microwavable so it can provide nearly continuous heat therapy. When used cold, the product conforms to contours, even at -20degreeF (-30degreeC), allowing comfortable soothing cold applications.
