The Kinetic Arm stands apart from traditional arm braces or sleeves with its innovative, multi-patented MuscleWeb® technology. Unlike conventional arm supports that typically support only one joint (either the elbow or shoulder) and often restrict or limit movement, the Kinetic Arm provides dynamic, multi-directional support to both the elbow and shoulder simultaneously, without limiting range of motion.

This external web of support is designed to optimize mechanics, reduce arm stress, and minimize the risk of fatigue, pain, and injury. It is the only arm support scientifically proven to offload dynamic arm stress, allowing athletes and active individuals to perform at their best while reducing the risk of overuse injuries.

Yes. The Kinetic Arm is backed by data and published scientific research, that has been validated by research and medical professionals.

No, the Kinetic Arm is not restrictive. It is designed to provide full range of motion while delivering responsive support to the elbow and shoulder. Its flexible, dynamic design ensures you can move freely during any activity, without compromising performance or comfort.

(If any restriction is felt, simply shift the chest part of the sleeve an inch or two towards the dominant arm or loosen the strap).

The Kinetic Arm K2 sleeves are designed to meet most regulations in sports.

However, rules are at discretion in different leagues and sports.

With regards to baseball and softball, there are no rules stating that you cannot wear a sleeve underneath uniform, as long as it is a solid color and is not distracting.

Little League Rule updated 2023 season: Rule 1.11a (3) Any part of the pitcher's undershirt or T-shirt exposed to view shall be of solid color. The pitcher's undershirt sleeves, if exposed, shall not be white or gray. Neoprene, if worn by a pitcher, must be covered by undershirt.

Materials:

The Kinetic Arm effectively reduces arm stress by offering dynamic support and stabilization to the elbow and shoulder during athletic or repetitive movements. Its revolutionary, multi-patented MuscleWeb® design provides targeted support to the joints during high-stress vulnerable ranges, all while allowing for a full range of motion.

Wearing this external arm support system has been scientifically proven to offload dynamic arm stress by providing multi-directional elbow and shoulder support during repetitive arm actions.

This is why Kinetic Arm has been regarded by customers as the best shoulder brace and best elbow brace for dynamic arm motions in activities and sports such as baseball, softball, volleyball, football, tennis, pickleball, and javelin.

The Kinetic Arm features a multi-patented MuscleWeb® design that mimics natural anatomical functions, providing reinforcement to muscles, ligaments, and joints for safer motion and reduced arm stress. This innovative technology uses strategically placed polymers to deliver targeted, multi-directional support to the elbow and shoulder, stabilizing joints during dynamic movements. The flexible web design offers activated support in vulnerable positions, offloading strain from critical areas while promoting optimal movement mechanics. This external reinforcement minimizes the risk of fatigue, pain, and overuse injuries, allowing athletes to maintain full range of motion and alleviate stress during repetitive arm actions.

The Kinetic Arm can help optimize mechanics by promoting safer anatomical ranges of motions, helping to improve joint alignment and stabilization to help improve mechanics and offload dynamic arm stress.

It works because it has an embedded MuscleWeb® design that gives a web of support to the elbow and shoulder to help reinforce the arm and efficient movement patterns without restriction.

With regards to overhand the throwing, these repetitive arm motions can cause fatigue to where the arm will have a tendency to lag behind as the body rotates which can cause excess stress on the elbow and impingement at the shoulder, and more stress on the labrum.

The Kinetic Arm overlays the elbow and shoulder to help reinforce and stabilize the arm to help improve mechanics and maintain safer ranges of motions.

The Kinetic Arm helps athletes gain and sustain power and velocity by optimizing mechanics and reducing arm stress. By minimizing fatigue and strain, it allows athletes to perform more repetitions and train with higher intensity, all while protecting the arm. This safer approach enables athletes to build strength and increase velocity over time. Many athletes who have worn the Kinetic Arm report being able to sustain and improve their velocity because they can train with greater intensity and safer progressions, experiencing less arm stress and fatigue.

No, the Kinetic Arm is not a performance enhancer but rather a protective device engineered to reduce dynamic arm stress on the shoulder and elbow. It does not alter skill, delivery, technique, strength, conditioning, or overall training. Instead, this stress-reduction sleeve helps safeguard the arm and prevent overuse injuries.

By promoting safer anatomical movement, the Kinetic Arm encourages cleaner mechanics and reduces stress during critical phases of dynamic motions like throwing, swinging, serving, and hitting. Its activated support engages when stress peaks in vulnerable passive ranges, providing targeted protection against strain and overuse while preserving natural motion and performance.

No, the Kinetic Arm does not cause reliance or dependency. Athletes continue to build strength and make the necessary physical adaptations, as they still generate the force required for their movements. The Kinetic Arm does not assist in moving the arm; it simply provides external support during motion. There have been no reports or evidence of muscle atrophy with long-term use because the muscles remain actively engaged during activities like throwing, swinging, serving, or hitting.

Peak stress occurs in passive ranges during dynamic arm movements, and the Kinetic Arm is specifically designed to provide activated support to the elbow and shoulder in these ranges, helping to dampen stress without interfering with natural mechanics. If you’re concerned about dependence, you can use it strategically as a workload management tool, wearing it on heavier workload days or during recovery to support arm health.

The Kinetic Arm is designed to be worn during training sessions, practices, and games to help manage arm stress and reduce the risk of injuries. For optimal results, athletes often wear the sleeve during high-intensity activities and recovery sessions, as it supports performance while minimizing fatigue and the risk of overuse injuries.

The ideal frequency of use may vary based on individual needs, preferences, and activity levels. To determine the best approach for your routine, consider consulting with a coach or sports health professional who can provide personalized guidance based on your goals and workload.

Yes, it is normal to have a little bagginess around the shoulder as this slack allows for full range of motion without restriction.

Please refer to fitting instruction video for a visual demonstration on how to make slight shifting adjustments to accommodate different ranges of shoulder support.

Whether or not to wear a shirt underneath the Kinetic Arm is largely a matter of personal preference.

It is advisable to try wearing the Kinetic Arm with and without a shirt during training or practice to determine which options feel more comfortable and allow you to perform your best. 

Some individuals find wearing a fitted shirt or base layer underneath adds an extra layer of comfort to help prevent any potential irritation or rubbing against the skin. If you have sensitive skin or are prone to chafing, wearing a fitted shirt underneath may provide an additional barrier and enhance overall comfort.

The Kinetic Arm base layer is available on our online stores, which has an ergonomic design to help keep seams off high abrasion areas, increasing durability and comfort, along with thumb access holes to help keep base layer in place while putting on Kinetic Arm or making adjustments.
