DYNAMIC SUPPORT

Softball players are prone to overuse injuries like rotator cuff strains and elbow tendinitis due to repetitive throwing and swinging motions. The Kinetic Arm offers a solution by providing dynamic support that stabilizes the elbow and shoulder joints without limiting movement. Its innovative design helps reduce strain, aids in recovery and performance, making it an essential tool for those looking to protect their arms while competing at their best.

THROWING MOTIONS
ADAPTIVE SUPPORT

Both underhand and overhand pitchers put a significant amount of stress on their arms and bodies when pitching. There are fundamental differences between the two pitching motions, but recent research has shown that the forces placed on the arm during the underhand fast pitch delivery are comparable to overhand pitching.

Understanding that all throwing motions cause repetitive strain, micro tears, and fatigue that can lead to overuse injuries. The Kinetic Arm can be worn as a tool to help offload excess stress without compromising performance.

IMPORTANT TO WEAR

Dual Joint Support

Wearing dual joint support is vital for softball players during dynamic movements like throwing and swinging, where the shoulder and elbow are closely connected. The Kinetic Arm stabilizes both joints, providing support in high-stress areas, which promotes optimal mechanics and reduces injury risk. This innovative design helps maintain proper alignment, preventing compensation patterns that can lead to overuse injuries.,

Nothing else like it

Until now, no product has offered unrestricted elbow and shoulder support that has been scientifically proven to reduce dynamic arm stress that can lead to fatigue, pain, and overuse injuries. Unlike standard sleeves, the K2 Sleeve utilizes a multi-patented MuscleWeb® Technology, a flexible design that dynamically reinforces muscles, ligaments, and joints, ensuring safer ranges of motion and reducing overall arm stress.

INTELLIGENT DESIGN
ACTIVATED SUPPORT

The Kinetic Arm’s multi-patented MuscleWeb® Design offers responsive, targeted support to the elbow and shoulder of softball players, activating during high-stress, passive ranges in motions like throwing and swinging. This stabilization reduces arm stress, minimizing injury risk and optimizing performance. By aiding in protection and recovery, the Kinetic Arm allows athletes to maintain strength and agility, enabling them to focus on their game with confidence.

Multi-Directional Supportive Design

Front shoulder support

Embedded polymers overlay the front of the shoulder, providing essential supportive tension to stabilize the joint and reduce stress during passive ranges when strain is at its highest. This web of polymers helps to offload stress from the musculoskeletal system by preventing the arm from lagging behind as the trunk rotates during dynamic arm motions. By alleviating stress on the biceps tendon and labrum, this external layer of support helps protect the front of the shoulder, reducing the risk of common overuse injuries to the biceps tendon, labrum, and rotator cuff.

FULL ELBOW SUPPORT

Built-in polymers strategically overlay the entire elbow, providing targeted support to the medial and lateral sides during dynamic arm movements. These external polymers help reinforce the joint, ligaments, and forearm muscles, offering essential stabilization, particularly to the medial elbow during external rotation and the late cocking phases of throwing, swinging, hitting, and serving. By externally stabilizing the elbow in passive ranges—where peak stress occurs—it helps reduce torque and dynamic stress, minimizing the risk of common overuse injuries such as medial epicondylitis, UCL injuries, and avulsion fractures.

BACK SHOULDER SUPPORT

Embedded polymers overlay the back of the shoulder, providing essential dual joint support and stabilization during force generation and arm deceleration. Acting as an active constraint, it minimizes joint stress by providing multi-directional support to the muscles and ligaments during dynamic arm movements. This polymer web design allows full range of motion while reinforcing the posterior shoulder to help offload stress by aiding in the eccentric control of the scapula and humerus, reducing distraction forces on the posterior shoulder and elbow, and delivering external support as muscles elongate.

reduce arm stress

The Kinetic Arm reduces arm stress for softball players by providing dynamic support to both the elbow and shoulder without limiting mobility. This dual-joint support helps offload dynamic arm stress, allowing players to perform at their best while protecting against fatigue, pain, and common injuries seen in softball, such as shoulder tendinitis and elbow strain.

OPTIMIZE MECHANICS

The Kinetic Arm optimizes performance for softball players by promoting safer arm movement mechanics and stabilizing the arm in its weakest ranges. It reduces stress from repetitive motions, helping to prevent fatigue, pain, and injuries. By allowing players to perform more repetitions effectively, the Kinetic Arm enhances strength and power without overloading the arms, enabling users to focus on skill improvement while minimizing injury risks.

"Excellent Product! I have searched high and low for good adjuncts to care to get my athletes back on the field as quickly and safely as possible and have finally found an awesome product to aid in injury prevention. Not to mention one that finally has some research popping up to back it. The Kinetic arm has been a game changer in my care plans for players returning from surgery or injury along with the athletes who are experiencing medial elbow discomfort with valgus stress or shoulder problems. I highly recommend!"

"I knew this was a must for many throwing athletes struggling with anything from labrum/rotator cuff injuries to UCL strains. I have now used it with a variety of my athletes in physical therapy and have seen it reduce pain with throwing from a 7/10 to a 0/10 by just simply putting it on. Rehabbing shoulder injuries in competitive throwing athletes can be a challenge because of the stress involved with the throwing motion, but with the Kinetic Arms' ability to offload stress while allowing proper biomechanics and full ROM, the process can be streamlined with better outcomes. Highly recommend 10/10!"

B. A pitcher shall not wear any item on the pitching hand, wrist, forearm, elbow or thighs which may, in the umpire’s judgment, be distracting to the batter. Batting gloves shall not be worn on the pitching hand. 

Yes, softball and baseball players wear the K2 sleeve on either arm to help with shoulder instabilities while hitting. This kinetic sleeve provides external support throughout the full range that will not interfere with their swinging motion.

Yes, the Kinetic Arm can be extremely beneficial for catchers, infielders, and outfielders, because they are also susceptible to various arm injuries like shoulder strains, elbow issues, and general wear and tear due to repetitively throwing.

Catchers especially, endure long and physically demanding games, and their arms can fatigue over time.

The Kinetic Arm gives targeted elbow and shoulder support while throwing, to help offload arm stress that can lead to pain, fatigue, and possible injury.

Wearing the Kinetic Arm increases overall arm stability and longevity without excessive fatigue so catchers can maintain better throwing mechanics resulting in more accurate and efficient throws, and more confidence behind the plate.
