Summary

Lateral epicondylalgia is a common musculoskeletal condition that approximately affects 1-3% of the general population. Several authors have found greater mechanical pain sensitivity in the radial nerve when compared with healthy subjects. Radial tunnel syndrome exhibits a similar clinical presentation to lateral epicondylalgia. Percutaneous electrical stimulation has shown reduce pain in several conditions. Percutaneous electrical stimulation on the radial nerve could cause an important relief in lateral epicondylalgia.

Hypothesis: Percutaneous electrical stimulation on radial nerve plus exercise therapy in patients with lateral epicondylalgia is better than sham percutaneous electrical stimulation plus exercise.

Conditions

  • Tennis Elbow

Interventions

OTHER

PENS plus exercise

The technique will be performed ultrasound-guided on the radial nerve, the places of the needle's insertions will be the following: * Needle will be placed at under the lateral intermuscular septum between the triceps brachii and brachialis, approximately 10cm superior to the lateral epicondyle * Needle will be placed at the upper third of the forearm on the posterior interosseous nerve after passing the arcade of Froshe The percutaneous electrical stimulation will be realized with a transcutaneous electric nerve stimulation (TENS) current: * TENS Frequency 2 Hz * TENS Pulse width - 250 microseconds * Duration - 30 minutes. * TENS Intensity - Increased at an intensity of visible motor response of the innervated musculature and maximal tolerable intensity. * Administration - One per week Self-management loaded exercises prescribed by a physical therapist, two times per week.
