Brief Summary

Achilles tendon is a frequent lower-limb tissue where tendinopathy may arise. Percutaneous Therapeutic Electrolysis (EPTE®) is an electronic device that enables to treat accurately, guided by an ultrasound, the tendon injured area by applying a galvanic current through an acupuncture needle. Thus, the first stage of physiological regenerative process may be obtained. Design: Randomized Controlled Clinical Trial. Objectives: To know the effectiveness of Percutaneous Therapeutic Electrolysis (EPTE®) versus a sham intervention at improving pain and function in patients who undergo Achilles Chronic Tendinopathy and to determine the efficiency of Percutaneous Therapeutic Electrolysis (EPTE®) with monopolar needle versus Percutaneous Therapeutic Electrolysis (EPTE®) with bipolar needle at improving pain and function in patients who undergo Achilles Chronic Tendinopathy. Participants: patients diagnosed with Achilles Chronic Tendinopathy. Setting. Infanta Leonor Hospital, Madrid, Spain. Experimental intervention: Percutaneous Therapeutic Electrolysis (EPTE®) with monopolar needle, 330 microamps, 1 min 20 sec versus bipolar needle. Sham intervention: the guide tube of the needle contacted with the skin and the device remained switched on to simulate its functioning.

Detailed Description

Tendinopathy is a common injury among athletes, where the incidence reaches 50%. Nevertheless, industrial workers as well as sedentary subjects may also undergo this pain condition.

Achilles tendon is a frequent lower-limb tissue where tendinopathy may arise. Achilles tendinopathy risk factors have been detailed, such as: age, mechanical axis deviation of lower limbs, excessive training load dosage, and type of work activity. The middle portion of the tendon is the area where Achilles tendinopathy is most likely to be located. Interestingly, correlation between pain severity and the degree of tissue degeneration by imaging diagnosis is hardly showed in chronic tendinopathy conditions. Thus, chronic tendinopathy pain may be mediated not only by peripheral but by central mechanisms.

Percutaneous Therapeutic Electrolysis (EPTE® System; Manual EPTE, 2014 IONCLINICS \& DEIONIC, S.L.) is an electronic device that enables to treat accurately, guided by an ultrasound, the tendon injured area by penetrating the skin with an acupuncture needle. A galvanic current goes through the device to the needle so that the first stage of physiological regenerative process may be obtained. That is due to a chemical reaction that leads to a controlled alkaline burn into the injured tissue and a subsequent basification of extracellular medium. That elicits an inflammatory response; the destroyed tissue is metabolized by phagocytosis process. Design: Randomized Controlled Clinical Trial. Objectives: To know the effectiveness of Percutaneous Therapeutic Electrolysis (EPTE®) versus a sham intervention at improving pain and function in patients who undergo Achilles Chronic Tendinopathy, and to determine the efficiency of Percutaneous Therapeutic Electrolysis (EPTE®) with monopolar needle versus Percutaneous Therapeutic Electrolysis (EPTE®) with bipolar needle at improving pain and function in patients who undergo Achilles Chronic Tendinopathy. Participants: patients diagnosed with Achilles Chronic Tendinopathy. Setting. Infanta Leonor Hospital, Madrid, Spain. Experimental intervention: Percutaneous Therapeutic Electrolysis (EPTE®) with monopolar needle, 330 microamps, 1 min 20 sec versus bipolar needle. Sham intervention: the guide tube of the needle contacted with the skin and the electrolysis device remained switched on to simulate its functioning.

Arm && Interventions

Group	Intervention	Description
Sham group	Sham comparator	Simulating of the electrolysis application.he electrolysis technique was simulated to be delivered. The guide tube of the needle contacted with the skin, located on the painful area, and the device remained switched on to simulate its functioning.
Experimental group 2	Experimental group 2	Electrolysis application with bipolar needle.
Experimental group 1	Experimental group 1	Electrolysis application with monopolar needle.

Primary Outcome Measures

Name	Time	Method
Pain intensity	5 min	Measured by Numeric Pain Rating Scale. Punctuation from 0 point up to 10 points. "0" no pain; "10" the most bearable pain.

Secondary Outcome Measures

Name	Time	Method
Location of the most thickened area	5 min	Assessed by ultrasonography. Distance (in mm) from the Achilles insertion up to the thickening onset.
Achilles tendon thickening	5 min	Assessed by ultrasonography. Thickening was considered when the thickness is 50% greater than the contralateral limb.
Length of the most thickened area	5 min	Assessed by ultrasonography. Distance (in mm) between the two extremes of the thickened area
Lower limb functionality	10 min	Measured by Visa-A Scale. Punctuation from 0 point up to 100 points. "0"point the most inability; "100" points complete functionality.
