Clinical Trial Summary

Introduction. The myofascial trigger point (MTrP) is a clinical entity related to different clinical pictures of pain. Dry needling (DN) would be the most appropriate therapeutic option for its treatment, although it has mild-moderate adverse effects, such as post-needling soreness (PNS). The exercise could be a strategy for its management, but no recommendations on the most effective mode have been found. Objectives 1. To determine the effectiveness of the exercise, differentiated according to the dominant mode (concentric, eccentric, isometric), in order to reduce the PNS of latent MTrPs. 2. To analyse the variables that, a priori, can influence the evolution of pain. Methods. Study design .A randomized clinical trial. Scenario Private or home-based consultation in Global Physiotherapy, Madrid, Spain. Participants. Voluntaries, with no symptoms in the triceps surae muscle,>18 years old, who present at least one latent MTrP in medial gastrocnemius. Subjects with: other pathologies of lower limbs, active MTrP in the medial gastrocnemius muscle, contraindications to DN, prior application of DN and/or other therapies in MTrPs during the three months previous to the study (in gastrocnemius muscles) will be excluded. Intervention After DN of the medial gastrocnemius muscle, participants will be randomly allocated to four groups (three experimental groups and one control). In the experimental groups, subjects will be instructed to perform exercise protocols, differentiated according to the dominant contraction (concentric, eccentric, isometric) in muscle the gastrocnemius previously treated. Outcome measures. Pain intensity, by analog visual scale (VAS). Pressure pain threshold (PPT), by analog algometer. Demographics and anthropometrics. Protocol. Before and immediately after DN, the PPT will be evaluated in the latent MTrP. Pain intensity will also be assessed using VAS at two times: the first referred to pain during DN and the other referred to PNS two minutes after DN. The subjects will then be randomly divided into: a control group without any intervention after DN, and three experimental groups with different exercise protocols (differentiated by the dominant contraction: 3 sets x 15 reps, 3s each contraction, 30s of rest between sets) . The pain intensity will be recorded again by VAS, after the exercise session and at 6h, 12h, 24h, 48h, 72h after DN. PPT will also be assessed 2min after DN, after the exercise session and at 24h, and 48h after DN.

Intervention

Other:
• Eccentric exercise
The exercise session will consist of 3 sets of 15 reps, 3´´ per rep, with 30'' rest between sets, of the previous treated gastrocnemius muscle (by DN). Each rep will be a pure eccentric contraction.
• Concentric exercise.
The exercise session will consist of 3 sets of 15 reps, 3´´ per rep, with 30'' rest between sets, of the previous treated gastrocnemius muscle (by DN). Each rep will be a pure concentric contraction.
• Isometric exercise.
The exercise session will consist of 3 sets of 15 reps, 3´´ per rep, with 30'' rest between sets, of the previous treated gastrocnemius muscle (by DN). Each rep will be a pure isometric contraction.
