Description of intervention(s) / exposure
The effect on pain threshold to pressure and strength will be compared in 3 arms of treatment with individuals with trigger points in the epicondyle area.
A single intervention will be performed on all arms. This session will be done on an individual basis. The application of the technique will be performed by a physiotherapist researcher with more than 5 years of clinical experience. We will monitor adherence with a pulse oximeter.
The first arm (intervention) will receive 50% blood restriction flow therapy with a SAGA FITNESS BFR cuff, and will perform 4 sets of 30 x 15 x 15 x 15 repetitions of epicondyle musculature eccentric exercises at 20% of 1 one-repetition maximum test (RM), with a rest time of 60 seconds between sets. The total duration of the intervention will be around 20 minutes.
The second arm (intervention) will perform isometric exercises at 80% of 1RM through a wrist extension with half of the forearm supported. 5 sets of 45 seconds, with 1 minute of rest between sets. We will monitor the adherence by direct observation.
All treatments will be delivered at the University Clinic of the Faculty of Nursing and Physiotherapy of the Universidad Pontificia de Salamanca, Madrid campus.

Comparator / control treatment
In arm 3 (control) participants will receive high power superinductive therapy equipment (Zimmer emField pro) will be used. The device generates a magnetic field of up to 3 Tesla with frequencies ranging from 1-100 Hz. The participant will remain seated with his/her arm resting on the table.The movable arm of the device will be placed 10 centimetres above the epicondyle area of the forearm, and set the prearranged program “pain in the lateral aspect of the elbow” for 15 min.

Summary
Brief summary
The aim of this study is to determine the effects of eccentric training with blood flow restriction compared to isometric exercise on pressure pain tolerance in people with the presence of epicondyle active or latent myofascial trigger points. The hypothesis is that exercise with flow restriction will increase the pain tolerance threshold compared to isometric exercise or the control group, which can lead to an improvement in the sensation of pain caused by myofascial trigger points.
