Clinical Trial Summary

Lateral epicondylitis (LE), also known as tennis elbow, refers to a painful condition at or around the lateral epicondyle of the humerus and common extensor tendon (CET) that is aggravated by dorsiflexion and/or supination of the wrist against resistance. Lateral epicondylitis is one of the most common injuries of the elbow, affecting 1-3% of the population.

Therefore, determining an effective intervention that helps manage the condition and lessens the financial burden is important. Passive physical modalities, including electrotherapy and orthotic devices, are common treatments for the management of elbow pain. Passive physical modalities are physical treatments involving a device that does not require active participation by the patient. In a systematic review, 2017, Dion et al examined the effectiveness of passive physical modalities for the treatment of soft tissue injuries of the elbow, but little evidence exists to support or refute their use.

Clinically, an invasive technique has appeared, known as Ultrasound-guided Percutaneous Neuromodulation (PNM). This minimally invasive intervention consists in the applicacion of a percutaneous electrical stimulation (PES) through an acupuncture needle-like electrode that is placed in close proximity to the nerve or motor point of the muscle with ultrasound guidance. At the clinical level, the PES is always used with the therapeutic aim of relieving chronic pain and neuropathic pain. Similarly, in sports, PES is used with the aim of improving muscular activity. Therefore, according to the characteristics and the therapeutic benefits of this technique, further research is needed to discover multiple clinical indications.

The aim of this pilot study was to examine the effects of a percutaneous neuromodulation intervention in patients with unilateral refractory lateral epicondylitis. Findings from this study may provide further evidence for the relevance of neural tissues in determining the elbow pain and may indicate effects of US-guided NMP technique on the rehabilitation and/or prevention of in patients with unilateral refractory LE.
