Effects of Dry Needling on Latent Myofascial Trigger Points of the Extensor Digitorum Communis
Effects of Dry Needling and Electrical Dry Needling on Latent Myofascial Trigger Points of the Extensor Digitorum Communis: A Randomized Clinical Trial
University Rovira i Virgili
150 participants
Jul 1, 2026
INTERVENTIONAL
Conditions
Summary
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.

Interventions
The skin will be disinfected with 0.5% alcoholic chlorhexidine. With the participant in supine position, a sterile needle will be inserted into the latent myofascial trigger point of the extensor digitorum muscle. Once the needle has reached the trigger point, 10 fast-in and fast-out movements will be performed. The number of local twitch responses will be recorded.
The skin will be disinfected with 0.5% alcoholic chlorhexidine. With the participant in supine position, a sterile needle will be inserted into the latent myofascial trigger point of the extensor digitorum muscle. Once the needle has reached the trigger point, the rotational dry needling technique will be applied according to the predefined study protocol.
The skin will be disinfected with 0.5% alcoholic chlorhexidine. With the participant in supine position, a sterile needle will be inserted into the latent myofascial trigger point of the extensor digitorum muscle. Once a local twitch response has been obtained, the needle will remain inserted and will act as the negative pole. An adhesive electrode connected to the positive pole will be placed approximately one centimeter from the needle. A TENS current will be applied for 15 minutes at a frequency of 2 Hz and a pulse width of 120 milliseconds. The intensity will be increased until visible, non-painful contractions of the extensor digitorum muscle are achieved.

With the participant in supine position, a sterile needle will be inserted into the latent myofascial trigger point of the extensor digitorum muscle. Once a local twitch response has been obtained, the needle will remain inserted in the trigger point. The metallic tip of the Pointer Plus Excel-II device will be placed in contact with the needle, and a TENS current will be applied for 3 minutes at a frequency of 2 Hz and a pulse width of 220 milliseconds. The intensity will be increased until visible, non-painful contractions of the extensor digitorum muscle are achieved.
