Introduction
Tennis elbow, medically known as lateral epicondylitis, is a condition that affects the tendons in the elbow and causes pain and discomfort in the outer part of the joint. Amongst other common repetitive strain injuries, our doctor sees more tennis elbow conditions coming in for shockwave therapy in Vancouver than other types of injuries. Despite its name, this injury is not limited to tennis players alone but can affect anyone who engages in repetitive arm and wrist movements. Traditional treatment methods for tennis elbow include rest, physical therapy, and anti-inflammatory medications. However, in recent years, a new treatment approach called Extracorporeal Shockwave Therapy (ESWT) has gained popularity for its effectiveness in relieving pain and promoting healing. This article explores the nature of tennis elbow, its causes and symptoms, and delves into the science behind ESWT and its potential as a game-changer in the treatment of this common injury.
- Understanding Tennis Elbow
Tennis elbow primarily affects the tendons and muscles that extend the wrist and fingers, attaching to the bony prominence on the outside of the elbow. The condition develops gradually over time due to repetitive stress and strain on the tendons, leading to microtears and degeneration. While tennis players are prone to this injury due to the repetitive motions involved in the sport, tennis elbow can also occur in individuals involved in activities such as painting, carpentry, gardening, and even typing.
The most common symptom of tennis elbow is pain and tenderness on the outer side of the elbow, which may radiate down the forearm. Other symptoms include weakness in the affected arm, difficulty in gripping or lifting objects, and pain exacerbated by activities that involve wrist and forearm movements. Something simple as holding a mug or a frying pan can increase the pain in the affected elbow.
- The Role of Extracorporeal Shockwave Therapy (ESWT)
ESWT is a non-invasive therapeutic technique that utilizes high-energy sound waves to treat various musculoskeletal conditions, including tennis elbow. The shockwaves are generated outside the body and transmitted through the skin to the affected area, stimulating the body’s natural healing process.
There are two types of ESWT commonly used: focused shockwave therapy and radial shockwave therapy. Focused shockwave therapy involves delivering targeted shockwaves to the specific site of injury, while radial shockwave therapy disperses shockwaves across a broader area. Both methods have shown positive results in the treatment of tennis elbow.
The exact mechanisms of how ESWT works are not yet fully understood. However, researchers believe that it triggers several biological responses, including neovascularization (formation of new blood vessels), increased production of growth factors, reduction of pain mediators, and stimulation of tissue regeneration. Additionally, ESWT may break down scar tissue and calcifications, promoting tissue healing and remodeling.
III. Effectiveness of ESWT in Treating Tennis Elbow
Numerous studies have demonstrated the effectiveness of ESWT in relieving pain and improving function in patients with tennis elbow. A randomized controlled trial published in the Journal of the American Medical Association (JAMA) compared ESWT with sham therapy (placebo) and found that ESWT resulted in significantly better outcomes in terms of pain reduction and improvement in grip strength. Similar findings have been reported in other studies, confirming the positive impact of ESWT on tennis elbow.
One of the advantages of ESWT is its non-invasive nature, as it eliminates the need for surgery or prolonged recovery periods. The treatment sessions are usually performed on an outpatient basis and require minimal downtime. However, it’s worth noting that some patients may experience mild discomfort or bruising in the treated area following ESWT.
The success rate of ESWT in treating tennis elbow varies among individuals, and multiple treatment sessions may be required for optimal results. A typical treatment plan consists of three to six sessions, spaced at weekly intervals. Many patients experience significant pain relief and functional improvement after completing the recommended course of ESWT. On average, our tennis elbow patients that receive shockwave therapy in Vancouver will start feeling better after the third treatment. Although this will depend on the severity and chronicity of the tennis elbow condition.
- Considerations and Future Directions
While ESWT has shown promising results in treating tennis elbow, it is essential to consider individual factors and consult with a healthcare professional before pursuing this therapy. Some individuals may not be suitable candidates for ESWT, such as those with open wounds or infections in the treatment area, individuals with certain medical conditions, or pregnant women.
Further research is also warranted to explore the long-term effects and optimal treatment protocols for ESWT. Additionally, combining ESWT with other therapeutic modalities, such as chiropractic, physical therapy or regenerative medicine techniques, may enhance outcomes and provide a comprehensive approach to healing tennis elbow.
Conclusion
Extracorporeal Shockwave Therapy (ESWT) has emerged as a promising and non-invasive treatment option for tennis elbow. By harnessing the power of high-energy sound waves, ESWT stimulates the body’s natural healing processes and promotes pain relief, tissue regeneration, and improved function. As more research is conducted and treatment protocols are refined, ESWT has the potential to revolutionize the management of tennis elbow, providing patients with a safe and effective alternative to traditional treatment methods.
