Immediate Effects of Blood Flow Restriction Compared to Isometrics on Pain Threshold and Strength in individuals with forearm myofascial trigger points

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.
