Neck pain affects about 70% of the global population and is known to be the fourth leading cause of disability. It is triggered by improper movement or posture and can be determined by the use of a visual analogue scale (VAS). Mechanical neck pain can occur due to myofascial trigger points (MTrPs). Hence, Martn-Sacristán applied the technique of deep dry needling (DDN) to inactive myofascial pain and found out the association of it with triggering neck pain.
Martn-Sacristán conducted a randomised control study to determine the effect of deep dry needling on individuals with neck pain. The 65 participants enrolled in the research study were between 18 and 65 years of age. They were divided into three significant intervention groups that included the Latent-MTrP group, the Active-MTrP group, and the Non-MTrP group.
The duration for the assessment of neck pain intensity was 1, 6, 12, 24, 48, and 72 hours, with a follow-up of one month. The statement of Consolidated Standards of Reporting Trials (CONSORT) was focused and its checklist was included in the study.
The number of local twitches, neck pain recognition, Neck Disability Index (NDI), pressure pain threshold (PPT), reproduction of patient pain, and VAS were the main factors that were assessed before, during, and after the intervention. The method includes the application of deep dry needling (DDN) and collecting the responses of patients with the assistance of a dichotomous variable. The high reduction in pain intensity was found in participants of the active-MTrP-DDN-group than in the non-MTrP-DDN-group (P 0.01).
Martn-Sacristán concluded that DDN therapy is more effective in reducing pain in the upper trapezius muscle in active-MTrP. Further clinical studies are required to investigate the pain reduction due to the application of dry needling with longer follow-ups, more sessions, and larger sample sizes for better determination of the precise location causing pain.
