What constitutes an injury?

4Arm Strong founder Lee Ramage accurately notes, “In baseball, players have only so many throws in their arm before something breaks.” The forearm and elbow were not built to sustain the strain baseball players- especially pitchers and catchers- so often place upon them.

According to a Healthline article medically reviewed by William Morrison, M.D., the forearm is made up of two connecting bones that join at the wrist: the ulna and the radius. It also includes muscles and tendons near and around the bones. An article by Winchester Hospital explains that forearm muscle strain occurs with “a partial or complete tear of the small fibers of the forearm muscles.” These injuries can occur over time, especially with baseball players. By simply stretching the forearm in the usual fashion, players can actually further injure these muscles and tendons they so heavily depend on to play the sport.

Another all-too-common injury for baseball players is the ‘Tommy John’. This injury is the result of tearing the ulnar collateral ligament, or UCL for short. According to an article by Baseball Reference, Tommy John, “results from repetitive use of the elbow during the violent motions involved with throwing a baseball.” An article from Web MD notes that, “Tommy John surgery repairs an injured elbow ligament. It’s most commonly done on college and pro athletes, especially baseball pitchers.”

What are the most common causes of an injury?

Dr. Morrison notes in an article from Healthline that common causes of a forearm injury can include muscle strain and overuse. Repetitive motions, like pitching a baseball over and over again, increase overuse and strain, thus upping the likelihood of a forearm or elbow injury. According to an article on Deep Recovery, pain can arise from “joint injuries, sports injuries, overuse conditions, fractures, and compressed nerves.”

As Driveline Baseball states, “actively pronating the forearm is imperative to protecting the pitching elbow. A reason often given is that pronating the forearm engages the pronator teres muscle.”

Which sports can cause forearm injuries?

Although injuries can result from daily activities, many forearm and elbow tendon injuries are associated with sports. According to an article by the Injury Treatment Group, forearm compression syndrome is common in “kayakers, canoeists and weight trainers.” Injuries can occur in anyone who uses their arms in a repetitive straining motion, like tennis players or rock climbers. Web MDnotes that torn UCL’s are common in baseball, as Ramage mentions, as well as tennis, gymnastics, soccer, football, wrestling, and cheerleading.

How does 4Arm Strong prevent injuries?

Ramage explains that a typical forearm stretch is ineffective in creating enough lengthening of the forearm muscles. In fact, it can actually worsen the injury by pulling at the elbow tendons themselves.

Unlike the typical stretch, 4Arm Strong pins the muscles in their shortest position. The knob on the device tilts the muscles in the opposite direction of the typical forearm stretch without pulling the elbow, thus protecting the elbow from the stretch and preventing further injury.
