Percutaneous Electrical Stimulation on Radial Nerve in Patients With Lateral Epicondylalgia
Effectiveness of a Combined Treatment Percutaneous Electrical Stimulation on Radial Nerve With an Exercise Program in Patients With Lateral Epicondylalgia
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.

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 effect of the immediate, short, medium and long-term of PENS on intensity of pain as measured by visual analogue scale (VAS) in patients with lateral epicondylalgia with random assignment to two treatments: PENS plus exercise program or Sham PENS plus exercise program.
Aim #2: The secondary aim of the study is to compare the effect of the immediate, short, medium and long-term of PENS on pain free grip strength, disability as measured by Patient Rated Tennis Elbow Evaluation (PRTEE) and DASH questionnaire and pressure pain threshold (PPT) and area and distribution of pain in patients with lateral epicondylalgia with random assignment to two treatments: PENS plus exercise program or Sham PENS plus exercise program, and determine if psychological factors (fear and avoidance and catastrophism) change with any of the treatments and if is related with the primary and secondary outcomes.

The current will not be working, and the needles will be placed during 30 minutes. - Administration - One per week |
What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Pain Intensity: visual analogue scale
Time Frame: Change from baseline to immediate (single session); 4 weeks; 8 weeks; 16 weeks; 28 weeks; 52 weeks
|
Pain intensity measured with a 100mm (0 - No pain - 100 The worst pain) visual analogue scale
|
Change from baseline to immediate (single session); 4 weeks; 8 weeks; 16 weeks; 28 weeks; 52 weeks
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Patient Rated Tennis Elbow Evaluation (PRTEE)
Time Frame: Change from baseline to 4 weeks; 8 weeks; 16 weeks; 28 weeks; 52 weeks
|
It is a 15-item questionnaire designed to measure forearm pain and disability in patients with lateral epicondylitis.
The PRTEE allows patients to rate their levels of tennis elbow pain and disability from 0 to 10, and consists of 2 subscales: pain and function.
|
Change from baseline to 4 weeks; 8 weeks; 16 weeks; 28 weeks; 52 weeks
|
|
Disabilities of the Arm, Shoulder and Hand (DASH) Questionnaire
Time Frame: Change from baseline to 4 weeks; 8 weeks; 16 weeks; 28 weeks; 52 weeks
|
It includes 30 items assessing (1) degree of difficulty during the preceding week in performing several physical activities because of problems in a upper extremity (21 items), (2) severity of each of the symptoms of pain, activity-related pain, tingling, weakness, and stiffness (5 items), and (3) the problem's effect on social activities, work, and sleep and its psychological impact (4 items).
Each item is answered on a 5-point scale ranging from 1 (no difficulty to perform, no symptom, or no impact) to 5 (unable to do, very severe symptom, or high impact).
The responses to the 30 items are summed to form a raw score that is then converted to a scale from 0 to 100 with a formula.
A higher score reflects greater disability.

To assess the fear of movement and pain-related fear.
The 11 items are scored 1-4, with total scores ranging from 11 to 44.
The addition of all the points obtained from each of the items results in the level of kinesiophobia, with higher scores indicating greater perceived kinesiophobia

Pain Catastrophizing Scale (PCS).
This tool is a 13-item questionnaire designed to measure the three components of pain-related catastrophizing: rumination, magnification, and helplessness, resulting in a unique score.
Each item is responded to on a 5-point scale (0 not at all, 4 all the time) relating the degree to which the individual experiences a thought or feeling of a painful situation.
