Arm Overuse Injuries

Softball is a dynamic and physically demanding sport that involves repetitive throwing and swinging, which can cause significant strain on the shoulder and elbow that often lead to pain and overuse injuries.

Softball pitchers are often overused from a young age, which sometimes results in a pitcher throwing over 1,000 pitches during a weekend tournament. The increased throwing volume puts pitchers at a higher risk for fatigue and injury due to continuous play and insufficient rest time.

Although throwing injuries are more common in pitchers and catchers, they are also happening with all position players.

Underhand vs overhanD
PItching motions

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.

We need to understand the fact that all throwing motions cause repetitive strain, micro tears, and fatigue that can lead to overuse injuries. We need to start being proactive by offloading stress externally with the Kinetic Arm.

Front shoulder support

Our patented MuscleWeb™ design overlays the anterior part of the shoulder giving a web of external support and stability to the shoulder while throwing and swinging. This design is engineered to mimic natural anatomical function to help reinforce the shoulder muscles, tendons, ligaments, and joints, during repetitive and explosive arm actions without restriction. Wearing this layer of protection will help to offload dynamic arm stress from common shoulder overuse sites like the biceps tendon, labrum, and rotator cuff.

FULL ELBOW SUPPORT

Our MuscleWeb™ design has built-in elastomers that overlay the elbow to provide targeted support and stability to the medial elbow during external rotation or late cocking phase while throwing. Having this web of external support helps to absorb stress when the elbow is in the most vulnerable ranges and when peak stress is the highest. Wearing this layer of elbow protection is imperative in helping to reduce dynamic valgus stress that can contribute to common elbow overuse injuries like epicondylitis, tendonitis, and UCL injuries.

Back SHOULDER SUPPORT

Our MuscleWeb™ design overlays the posterior side of the shoulder to help reinforce and support the decelerator muscles and scapula area during deceleration while throwing. The embedded elastomers give a web of external support to help stabilize the shoulder and absorb stress at end ranges when peak stress is the highest. Wearing this layer of protection can help the shoulder from ending up in an anterior tilt position which can cause impingement and shoulder overuse injuries, which can also lead to increased elbow stress and injury.

The K2 kinetic sleeve is the best option for softball pitchers. This slim-fitted sleeve gives unrestricted dynamic support to the arm while throwing, by stabilizing the elbow and shoulder when the arm is in the weakest ranges.

The compressive element of the kinetic sleeve helps to secure the humeral head of the shoulder so it stays compressed into the glenoid of the shoulder throughout the windmill motion, helping to offload the stress at the shoulder.

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.

"My daughter has a shoulder injury and the Kinetic Arm has helped her be able to continue to play (along with PT). She plays catcher and corners and the arm takes the strain off of her shoulder and allows her to throw with less pain. She says it is very comfortable to play and hit in. I wish we had tried this product sooner."

"My daughter had something wrong with her arm and she had a decrease in velocity while pitching and throwing. She said her arm wasn't sore at all, but she had a hard time throwing from 3rd to 1st on a line. Something wasn't right. After using Kinetic Arm sleeve for a while, maybe just over a week, she was back to normal. So I bought one for my son, and how we have two sleeves!"

Kau Kris

★★★★★

"My daughter is a national level softball player. She has dealth with shoulder pain from her craft for 3 years. She has used the brace in 4 practices and 3 scrimmages in the past month and she told me her aching pain is gone and the brace does not impact her play negatively. So far it seems like this is the solution we were looking for. "

"I bought this for my daughter playing softball. She was just coming off of 2 months physical therapy and PRP treatments for extreme tendonitis and bursitis in her throwing rotator cuff. Still complained of pain when throwing. First time wearing the K2 she was pain free. I have already noticed an increase in velocity as a bonus. Definitely works as described."
