Comparative Effect of MEP With or Without Current Emission in the Treatment of Cervical Pain in MTrPs of the Trapezius
Condition: Neck Pain, Posterior; Myofascial Pain Syndromes
MeSH terms: Myofascial Pain Syndromes; Fibromyalgia; Neck Pain
Study type: Interventional

Summary: 
      Myofascial pain syndrome (MPS) is initial to other pathologies such as neck pain or tension
      headaches; the symptoms that are located on the area of myofascial trigger points (MTrPs) of
      specific references in different muscles. MTrPs are palpable, tense bands found in stiff
      muscle that cause pain and swelling. They affect the disruptive soft tissues, resulting in
      deterioration of the muscle and fascia; effects that can be transferred further, through the
      myofascial chain to distant tissues, inducing the referred pain that is the main feature of
      MPS. MTrPs are treated with stretching, massage, analgesics, acupuncture, dry needling,
      electrical stimulation, and ultrasound. Percutaneous microelectrolysis (MEP®) is a new
      technique that uses galvanic current of low intensity and high density. Based on the previous
      reviews, the investigators consider that the use of MEP in individuals who have MTrPs in the
      trapezius is more effective than acupuncture treatment. Objectives: To assess the effect of
      MEP as a technique for treating pain in MTrPs of the trapezius muscle compared to without
      current emission, analyzing function, pain and strength in MTrPs before and after both
      treatments.

      Materials and methods: Randomized controlled clinical research. The study population consists
      of patients of both sexes between 20 and 60 years of age, with medical referral for neck pain
      who do not currently receive physiotherapeutic treatment, pain of at least 1 month of
      evolution, presenting on both sides of the trapezius MTrPs muscle and having signed the
      informed consent. They will be randomly distributed into: group treated with acupuncture
      (control) and group treated with MEP. Both will take place over 3 weeks, with one session per
      week. The evaluation is carried out through the visual analogue scale (VAS), measurement of
      force with a dynamometer and mobility with a goniometer. The score will be recorded on a
      validated neck pain questionnaire (NPQ). The Chi-Square test (test) will be implemented for
      the analysis of categorical data and the &quot;t&quot; test for paired data for quantitative
      data, based on a significance level of p˂0.05 in all cases.
