A tennis elbow strap is a supportive device worn around the forearm to alleviate pain and discomfort associated with tennis elbow, a condition characterized by inflammation of the tendons that attach to the outside of the elbow. It works by applying pressure to the affected area, which helps to reduce swelling and pain, and by providing support to the muscles and tendons, which helps to prevent further injury.
Tennis elbow straps are typically made of elastic material, such as neoprene or spandex, and are adjustable to ensure a snug and comfortable fit. They are often worn during activities that aggravate tennis elbow, such as playing tennis, lifting weights, or using hand tools. In addition to providing pain relief and support, tennis elbow straps can also help to improve range of motion and grip strength.
