What’s the Evidence for the Use of Cold Laser Therapy in Treating Tennis Elbow in Athletes?

The tennis elbow, known in the medical world as lateral epicondylitis, poses a significant challenge to athletes across the globe. But in recent years, cold laser therapy or low-level laser therapy (LLLT) has gained traction as a potential treatment for this painful condition. But just how effective is this treatment? Let’s dive into the studies, trials, and reported outcomes to uncover the facts.

An Overview of Lateral Epicondylitis

Lateral epicondylitis, commonly referred to as tennis elbow, is a prevalent issue amongst athletes. This condition causes pain and discomfort in the elbow joint, which can significantly impact an athlete’s ability to perform.

Research from PubMed and Google has shown that conventional treatments include physiotherapy, rest, and in some severe cases, surgery. But in recent years, a new form of treatment has emerged – cold laser therapy, also known as low-level laser therapy or LLLT.

LLLT uses low-intensity lasers to stimulate cell repair and reduce inflammation. But what does the research say about its effectiveness in treating tennis elbow?

The Science Behind Low-Level Laser Therapy

Low-level laser therapy (LLTL) has become increasingly popular for its potential in treating various medical conditions. This treatment uses low-intensity lasers or light-emitting diodes to alleviate pain and stimulate healing at a cellular level. The laser’s energy can penetrate the skin and soft/hard tissues, offering a non-invasive and pain-free treatment option.

A quick search on PubMed or Google Scholar reveals numerous studies and trials examining the effectiveness of LLTL in treating various conditions, including lateral epicondylitis.

Clinical Trials and Studies on LLLT for Tennis Elbow

A significant body of research exists in understanding the effectiveness of LLLT in treating tennis elbow. Several controlled trials and studies have been conducted to evaluate this treatment option’s efficacy and safety.

For instance, a study by Stergioulas A’s group, published on PubMed, involved 52 tennis elbow patients. Half of the patients received LLLT, while the control group received placebo treatment. The study found that the LLLT group reported less pain and improved grip strength compared to the control group.

Another trial published in The Lancet involved 82 patients. The findings were similar: patients who underwent LLLT showed a marked reduction in pain and improved functionality.

While these studies provide promising results, it’s essential to note that more extensive, long-term studies are needed to establish LLLT as a standard treatment for tennis elbow.

Reported Outcomes of LLLT for Tennis Elbow

Aside from clinical trials, numerous reported outcomes from patients and practitioners alike suggest LLLT’s potential effectiveness in tennis elbow treatment.

Patients undergoing this therapy have reported reduced pain levels and enhanced mobility, contributing to improved overall quality of life. Furthermore, practitioners have reported success with LLLT, noting improved patient satisfaction and reduced reliance on pain medication.

However, as with any treatment, results can vary greatly from person to person. Factors such as the severity of the condition, individual response to treatment, and adherence to therapy protocols can all influence outcomes.

Reviewing the Evidence: LLLT for Tennis Elbow

In the light of the available evidence, it appears that LLLT could be a promising treatment option for those suffering from tennis elbow. The trials and studies conducted so far show potential for pain reduction and improved functionality.

However, it is crucial to remember that while this evidence is encouraging, it does not yet constitute a definitive endorsement of LLLT for tennis elbow treatment. Further, larger-scale research is needed to confirm these findings and establish the treatment’s long-term safety and efficacy.

In conclusion, while we cannot yet say with certainty that LLLT is the ultimate solution for tennis elbow, the current evidence suggests that it holds significant promise. As with any treatment, it is always recommended to consult with a medical professional before initiating any new therapy.

Further Research into the Application Technique of LLLT

The application technique of low-level laser therapy (LLLT) is a critical factor in its effectiveness in treating tennis elbow. Several factors come into play, such as the laser’s power, the duration of the therapy, and the target area’s specifics.

A systematic review published in PubMed highlights the importance of customizing these factors to the patient’s specific condition for the treatment’s success. For example, the severity of the lateral epicondylitis can dictate the power of the laser used and the duration of each therapy session. In more severe cases, the laser’s power may need to be increased, and the treatment sessions may need to be longer.

Additionally, the patient’s physical characteristics, such as skin color and thickness, can also affect the application technique. Darker and thicker skin may require a higher power setting on the laser to ensure the light penetrates deeply enough to stimulate the healing process.

In a meta-analysis of randomized controlled trials, a variation in the application technique was observed. In some studies, a static application technique was used, where the laser was held in one place for a set duration. In other studies, a dynamic technique was used, where the laser was moved around the impacted region. The meta-analysis concluded that more research is needed to determine which technique is more effective.

This potential variation in the application technique of LLLT indicates the importance of having a trained professional administer the laser therapy.

LLLT Vs. Conventional Treatments: A Comparative Analysis

When comparing LLLT to conventional treatments for tennis elbow, such as corticosteroid injections and physical therapy, several factors come to light.

Corticosteroid injections are a popular treatment for lateral elbow pain, but they come with potential side effects, such as skin discoloration and the weakening of the tendon. On the other hand, LLLT is non-invasive and does not have these side effects.

Physical therapy, another common treatment, requires active participation from the patient and can be time-consuming. In contrast, LLLT is passive and can be administered in a relatively short period.

Several comparative studies found on Google Scholar show that patients undergoing LLLT reported less pain and increased grip strength compared to those undergoing traditional treatments. However, this does not necessarily mean that LLLT is superior.

It is crucial to consider that the effectiveness of a treatment can vary greatly depending on the individual’s specific condition and response to therapy. Therefore, the choice of treatment should be made on a case-by-case basis, with the guidance of a medical professional.

Conclusion

Low-level laser therapy appears to hold promising potential as a treatment for tennis elbow, particularly for athletes looking for non-invasive alternatives to traditional treatments like corticosteroid injections and physical therapy.

The clinical trials and systematic reviews conducted so far suggest potential benefits, such as pain reduction and improved grip strength. Patient and practitioner reports also hint at enhanced mobility and improved quality of life with LLLT treatment.

However, we must remember that these findings are based on short-term studies. More extensive, long-term research is needed to validate the efficacy and safety of LLLT for treating tennis elbow in the long run.

As further research unfolds, it is hoped that a clearer picture will emerge regarding the application technique, ideal treatment duration, and comparative effectiveness of LLLT against conventional treatments. For now, the choice to undergo LLLT should be made in consultation with a medical professional, considering the individual’s specific condition and treatment response.
