Percutaneous electrolysis is based on the application of a galvanic current through an acupuncture needle. The underlying mechanisms that explain the efficacy of this technique are not completely well understood. The objective is to delve into the neurophysiological analgesic effects of percutaneous electrolysis. Participants will be assigned to one of three intervention groups. The analgesic effects of the technique will be evaluated by means of variables related to endogenous pain modulation.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Sham intervention | Sham Comparator | The needle will be inserted for 90 seconds without galvanic current. |
|
| Low intensity percutaneous electrolysis | Experimental | Galvanic current will be applied with an intensity of 0.3 mA for 90 seconds. |
|
| High intensity percutaneous electrolysis | Experimental | Participants will receive three impacts of galvanic current with an intensity of 3 mA for 3 seconds each. |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Sham intervention | Other | The needle will be inserted into the right common extensor tendon of the epicondyle for 90 seconds without galvanic current. |
|
| Measure | Description | Time Frame |
|---|---|---|
| Changes from baseline in Pressure Pain Thresholds (PPT) | PPTs will be measure by algometry in the common extensor tendon of the epicondyle, bicipital groove and tibialis anterior muscle (all of the right side). | Baseline and immediately after the intervention |
| Measure | Description | Time Frame |
|---|---|---|
| Changes from baseline in Conditioned Pain Modulation (CPM) | CPM will be assess by upper extremity submaximal effort tourniquet test with algometric measures in the common extensor tendon of the epicondyle, bicipital groove and tibialis anterior muscle (all of the right side). | Baseline and immediately after the intervention |

| Low intensity percutaneous electrolysis | Other | A single impact of galvanic current will be applied in the common extensor tendon of the epicondyle (right side) with an intensity of 0.3 mA for 90 seconds. |
|
| High intensity percutaneous electrolysis | Other | Three impacts of galvanic current will be applied in the common extensor tendon of the epicondyle (right side) with an intensity of 3 mA and a duration of 3 seconds each. |
|
| Changes from baseline in Temporal Summation (TS) |
Assessed by Verbal Numeric Rating Scale (11-point). 10 consecutive pressures will be applied in the three previous locations (epicondyle, bicipital groove and tibialis anterior) with the algometer at the intensity of the pressure pain threshold |
