A counterforce brace is a specialized strap designed to wrap around the forearm, providing targeted compression. It serves as a supportive tool for individuals experiencing tennis elbow (lateral epicondylitis), aiming to alleviate pain and reduce strain from repetitive overuse of forearm muscles and tendons.
Proper Application of the Brace
Applying a counterforce brace correctly is essential for its effectiveness in managing tennis elbow. Begin by sliding the brace onto the affected forearm, ensuring it is positioned approximately one to two inches (2-5 cm) below the elbow crease. The goal is to place the brace over the muscle belly, not directly on the bony prominence of the elbow where pain is often felt.
For tennis elbow, place the brace’s padded section over the extensor muscle mass on the outside of the forearm. To confirm the correct spot, make a fist or actively extend your wrist; the brace should be situated over the contracting muscles that become prominent. This ensures the brace directly influences the muscle group responsible for the strain, providing optimal support by redirecting forces away from the injured tendon.
Secure the brace firmly, providing noticeable compression without feeling overly tight or restrictive. When you make a fist, you should feel pressure, but tension should subside when your hand is relaxed. Avoid applying the brace so tightly that it causes numbness, tingling, or discoloration in the hand or fingers, as this indicates restricted circulation.
How the Brace Works
A counterforce brace functions by applying targeted pressure to the forearm’s extensor muscles. This compression disperses forces generated by muscle contractions, broadening the area of stress distribution. By doing so, the brace creates a “secondary origin” for these muscles further down the forearm, away from their inflamed attachment point at the elbow.
This mechanism helps to offload the strain on the common extensor tendon, particularly the extensor carpi radialis brevis (ECRB), at its insertion on the lateral epicondyle of the elbow. Additionally, the brace can restrict the full expansion of the muscle belly during contraction, which may diminish the overall force transmitted to the tendon origin. Studies suggest that this targeted support can reduce forces on the tendons by an estimated 13% to 15%, contributing to immediate pain relief and improved grip strength for many individuals.
When and How Long to Wear the Brace
Wear a counterforce brace primarily during activities that aggravate tennis elbow symptoms, such as sports, repetitive work tasks, or lifting objects that strain the forearm. This helps reduce immediate pain and protect injured tendons.
Avoid wearing the brace continuously, especially during rest or sleep. Prolonged compression can reduce circulation and impede healing. While some find night use helps with pain and sleep, only do so if it remains comfortable and causes no discomfort, tingling, or numbness.
The duration of brace use can vary, but many healthcare professionals suggest wearing it for several weeks to assess its impact on symptoms. Consistent daily use during activity may lead to better outcomes. As pain subsides and healing progresses, gradually reduce reliance on the brace until it is no longer needed. Always consult a healthcare professional for personalized guidance.
Common Issues and Brace Care
Users of counterforce braces may occasionally experience issues such as discomfort, skin irritation, or sensations like numbness or tingling. These often suggest the brace is too tight or improperly positioned. Adjusting the tightness or slightly repositioning the brace can typically resolve these concerns, aiming for a firm yet comfortable fit. If pain persists or symptoms worsen despite proper application, seeking advice from a doctor or physical therapist is important.
Caring for the brace usually involves hand washing with mild soap and cool water, followed by air drying. This routine helps maintain hygiene and the brace’s material integrity. A counterforce brace functions as a supportive aid and works best when integrated into a comprehensive management strategy for tennis elbow.
