Effects of Dry Needling on Latent Myofascial Trigger Points of the Extensor Digitorum Communis

This randomized single-blind clinical trial aims to compare the effects of different dry needling and electrical dry needling techniques applied to latent myofascial trigger points in the extensor digitorum muscle of the dominant forearm in healthy adults. Participants will be randomly allocated to one of five groups: a control group, a Hong fast-in and fast-out dry needling group, a rotational dry needling group, a bipolar electrical dry needling group, or a monopolar electrical dry needling group. The main outcomes will be post-needling soreness intensity and duration. Secondary outcomes will include pain during the needling procedure, pressure pain threshold assessed by algometry, handgrip strength, range of motion of finger flexion and wrist palmar flexion, perceived comfort during the intervention, and perceived interference of post-needling soreness with daily activities. Assessments will be performed at baseline, 5 minutes after the intervention, and at 24, 48, and 72 hours after the intervention.
