Outer Elbow Pain & Tennis Elbow Pain

RapidForce® Shapes stabilize and support the muscles, tendons, and ligaments in the outer elbow. The L Shape is designed to reduce swelling by gently lifting the skin above the pain point, which can help circulate blood, oxygen, fluids, and nutrients to an injury site.

Repetitive arm motions, like those made in many sports and day-to-day activities, can cause damage to extensor carpi radialis brevis (ECRB) muscle, which is near the outer elbow. The ECRB muscle is critical to arm bending and wrist straightening as well as other wrist, arm, and hand movements.

Because outer elbow pain and tennis elbow are typically caused by the overuse of the elbow joints or tendons, athletes who participate in arm-centric sports such as tennis and racket sports, golf, swimming, rowing, baseball, and weightlifting are all at risk for straining the elbow or inflaming the ECRB. Elbow pain and elbow injuries are somewhat common among workers in the construction, manufacturing, painting, and culinary industries too.

People managing an outer elbow injury can expect to feel a dull ache, tenderness, or a burning feeling in the elbow itself, but the pain may spread to or be experienced solely in the wrist, fingers, or neck. Injured people will often report pain in the outside or lateral part of the arm, pain in the back of the forearm, elbow pain when straightening the arm, or pain when lifting the arm. The elbow bone might appear swollen or inflamed, and it may be difficult or painful to grip objects, lift items, or make minute movements, such as typing or turning a screwdriver.

The RapidForce® L Shape (outer left arm) and Reverse L Shape (outer right arm) are designed to help reduce elbow pain. The L Shape’s central core stabilizes the elbow at its most painful point, and the two stretchable arms help anchor and support the surrounding muscle. RapidForce® Shapes also provide some mechanical lift, which is designed to literally lift the upper layers of the skin and create more space for blood, oxygen, fluids, and healing nutrients to reach the injury site.

RapidForce® Shapes are unlike any other pain-relief product on the market today. Each Shape’s patented design was carefully developed and perfected by a team of physical therapists, athletic trainers, engineers, and an ultrasound technician who sought to create a product that supports the muscles and helps relieve pain caused by muscle, tendon, joint, and ligament injuries. RapidForce® Shapes are used by athletes at all levels, including professional athletes, semi-pro athletes, and people who lead or want to lead an active lifestyle.
