Overview
Brief 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 in patients with lateral epicondylalgia is better than sham percutaneous electrical stimulation
Detailed Description
Randomized, double-blind, placebo controlled clinical trial, using Percutaneous Electrical Nerve Stimulation (PENS). PENS is technique to provide a transcutaneous electrical nerve stimulation current throughout needling filaments place close to the nerve. Study Aims: Aim #1: The primary aim of the study is to compare the immediate effect of a single session of PENS on pressure pain sensitivity as measured by pressure pain threshold in patients with lateral epicondylalgia with random assignment to two treatments: PENS or Sham PENS Aim #2: The secondary aim of the study is to compare the immediate effect on pain free grip strength, on intensity of pain as measured by visual analogue scale (VAS) in patients with lateral epicondylalgia with random assignment to two treatments: PENS or Sham PENS.
