Rotator Cuff Pain

RapidForce Star Shape - Muscle Support & Pain Relief System

RapidForce® Shapes stabilize and support the muscles, tendons, and ligaments in the rotator cuff. The Star 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.

The group of muscles and tendons that make up the rotator cuff are responsible for keeping the arm stabilized and connected to the shoulder socket. A rotator cuff strain can be identified by a dull ache deep within the shoulder, pain or difficulty lifting or rotating the arm, frozen shoulder, a cracking sensation, or sudden-onset pain if the rotator cuff is injured during an impact.
Rotator cuff pain is most often the result of repetitive and vigorous overhead sports motions, such as swimming, spiking a volleyball, swinging a tennis racket, or pitching a baseball, but they can also occur in when the shoulder receives an impact, as it might during a football tackle or in a wrestling match. On-the-job arm movements can also be culprits, such as those made at construction, carpentry, or painting sites. Pain in the rotator cuff is usually a matter of small tears in the muscle, deterioration of the tissue or tendons, or general irritation.
The RapidForce® Star Shape is designed to help reduce rotator cuff pain of this sort. The Shape’s central core is placed atop the tendons and/or muscles of the rotator cuff causing the most pain, stabilizing the pain point. The Star Shape’s arms are then stretched outwards, creating an ultra-strong support system for the surrounding muscle and tissue. The Shape is also designed to provide some mechanical lift, which gently lifts the skin, creating more subcutaneous space within the arm for the healing fluids, nutrients, oxygen, and blood to flow to 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.

Time it Right

While RapidForce® Shapes can be applied at any time, they should be applied 1–2 hours before beginning strenuous physical activity. The Shapes can start working is as little as two hours, but some applications take up to four hours.

Prep Skin Thoroughly

Wash and dry the skin to remove oils, moisture, and dirt. Trim or shave body hair; this helps create a more secure bond and more comfortable removal. Apply the provided Skin Tac liquid adhesive wipe. Allow 30 seconds for it to dry.

Customize Stretch

Secure the Shape’s central core to the most painful spot. For daily wear or moderate-to-light athletics, a mild stretch of 1/2” is ideal. Application instructions vary based on Shape, so read and follow the instructions mailed with your shape(s).

Secure Bond

With both the Shape and the skin at room temperature, carefully begin applying the shape. Once the shape is secure, rub it vigorously to maximize adhesive bond to skin.

    Peel off the middle backing of one of the arms, leaving the end tab in place. While stabilizing the center with one hand, customize stretch for level of activity and place straight out from the center. Smooth the fabric onto the skin, moving from the center of the Star Shape outwards. Remove the backing from the end tab and place on the skin. Do not stretch this small piece. Press over the entire arm for about 10 seconds to secure the bond. Repeat for all arms.

    4. Feel Relief and Remove

    You may begin feeling relief within a few hours. However, it could take up to 24 hours. RapidForce shapes can provide pain relief and muscle support for up to five days but can be removed at any time. To remove, pull from the end of the arms to the center. If hair is present, pull in the direction of the hair’s growth to reduce discomfort. For easier removal, use mild warm water in the shower and then remove the shape slowly.
