DYNAMIC ARM SUPPORT
FINALLY A SOLUTION
The rise of overuse injuries in baseball continues, with players at all levels, from youth to the majors, experiencing arm issues at an alarming rate. Common overuse injuries include UCL tears, rotator cuff strains, and labrum injuries, often leading to long-term damage or surgery.
The Kinetic Arm offers the most promising, science-backed medical-grade solution to this growing problem. Players can now safeguard their arms while optimizing performance—ushering in a new era of a much-needed evolution in baseball arm care.
The Kinetic Arm incorporates MuscleWeb® activated stabilizing technology, a flexible, multi-directional support system designed to protect the elbow and shoulder during dynamic movements without restriction. Its multi-patented design delivers activated stabilization in the arm’s passive ranges, where stress is highest, reducing strain and injury risk. This unique combination of unrestricted mobility and medical-grade joint support makes the Kinetic Arm essential for safeguarding athletes' arms while optimizing their performance.
The Kinetic Arm provides medical-grade dual-joint stabilization to both the elbow and shoulder during the high-stress phases of throwing and swinging in baseball. Its MuscleWeb® bonded polymer system delivers external support that helps reduce dynamic arm strain, allowing athletes to maintain consistent mechanics and manage the repetitive stress that can contribute to fatigue, soreness, and overuse strain. This biomechanics-driven support technology reinforces both joints simultaneously, helping athletes optimize movement efficiency while minimizing the mechanical load that accumulates over innings, games, and seasons.
Wearing the Kinetic Arm helps optimize performance by supporting efficient mechanics and reducing arm stress during high-intensity throwing and swinging. By providing medical-grade stabilization to the elbow and shoulder, it helps maintain proper alignment and reduce inefficient compensatory movements. This external support reinforces the arm in vulnerable ranges to help minimize repetitive mechanical stress that can lead to arm fatigue, supporting the arm during necessary reps needed to build strength and power without overloading the arm. Allowing full range of motion with essential support to both joints—so you can maximize performance while minimizing risk.
The Kinetic Arm supports active performance and recovery by providing medical-grade external stabilization to the elbow and shoulder, reducing strain during dynamic arm movements. It helps stabilize joints in vulnerable positions, promoting proper alignment and reducing unnecessary stress. This medical-grade external arm system supports recovery and aids in injury prevention by allowing athletes and active individuals to train and build strength while reducing strain that can lead to arm fatigue, discomfort, and overuse related issues.
With more than a decade of research and data collected across elite sports performance labs nationwide, Kinetic Arm has been extensively studied for its effects on elbow torque and dynamic arm stress during high-demand movement. Using advanced wearable IMU sensors and 3D motion-capture technology, testing captured precise, real-time biomechanical metrics during throwing and other high-stress arm actions.
This data has been analyzed by experienced researchers, biomechanists, and performance professionals to better understand how dynamic, external arm stabilization can support movement efficiency, manage mechanical load, and reduce arm strain during repetitive, high-intensity activity.
★★★★★"The Kinetic Arm definitely shows promising uses for not only rehab professionals but also for performance coaches. I foresee that this prototype can usher in a new era of health and performance for throwing athletes."

★★★★★As an orthopedic physical therapist, I really like this product for not only recovery from elbow and shoulder injuries, but also in helping to reduce said injuries in the first place. I have suggested this to numerous baseball and volleyball players who love its results! Fantastic product and I’m glad you guys took the time to think about how to make something like this because it’s definitely making a difference.

★★★★★"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 this product!"

★★★★★"I have now used it with a variety of my athletes in physical terapy 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 becasue 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!

★★★★★"The Kinetic Arm has the capacity to reduce harmful stress on the elbow and its non contractile structures, while at the same time allowing for sustained duration and intensity for practices sessions with overhead athletes. The applicability of this product may extend to various sports including baseball, football, tennis, and track and field athletes. As a physical therapist and strength and conditioning coach, I would strongly consider using this product for rehab and training alike to ensure the long term health of my overhead athletic patient or client."

★★★★★"Not only does the data show a decrease in elbow torque, the Kinetic Arm has the potential to be a great tool for performance and rehabilitation for throwing athletes. After testing it myself and with a few of our golfers, it helped alleviate elbow torque and stress off the trail arm. I'm excited to see the growth of the Kinetic Arm in multiple sports."

★★★★★"I have been a Physical Therapist for over 20 years. I worked with a shoulder specialist, have been OCS certified since 2010, am a Champion Performance Specialist, and am a Certified Arm Care Specialist. More importantly, I am a father whose son plays high school and travel baseball. My son had an arm issue. We have used the kinetic arm (K1 initially) and now the K2 for essentially every throw he has made for the last 2 years. He wears it under his jersey during the games and at every practice. It has been a game changer for my son and essentially all my patients in the last 2 years that have had arm issues."

Kinetic Arm is worn by baseball players at every level, from youth leagues to Division I, including pitchers, catchers, and position players. Constructed with medical-grade materials and a low-profile design, it fits comfortably under uniforms and is worn in practice and in game without restricting movement.
This lightweight, non-restrictive arm stabilizer provides dynamic support to both the shoulder and elbow, helping manage arm stress while maintaining full range of motion. Whether on the mound, behind the plate, or in the field, Kinetic Arm delivers movement-responsive support designed to work with the demands of baseball—without compromising performance.
For young baseball players, managing arm stress during growth and skill development is especially important. As youth athletes progress through repetitive throwing and swinging—often while navigating growth spurts—the shoulder and elbow can be exposed to increased mechanical demands.
The Kinetic Arm Youth Sleeve is designed to support young baseball players as they train, compete, and develop their skills through repetitive throwing and movement. Constructed with medical-grade materials and powered by MuscleWeb® technology, it provides dynamic, non-restrictive support to both the shoulder and elbow to help manage arm stress and support efficient mechanics during growth and high-use phases—without limiting natural motion.
The Kinetic Arm is trusted and worn by professionals at all levels of baseball, from Little League World Series participants to Major League Baseball stars. It has gained significant recognition in Japan, particularly in Nippon Professional Baseball (NPB), where prominent athletes like Shota Imanaga, now in the MLB, use it for recovery, performance, and protection. Its proven effectiveness and medical-grade construction, has led to widespread adoption in professional training programs across MLB, MiLB, NPB, NFL, ATP, and other elite leagues both nationally and internationally.
