title: Ultrasonography in myofascial neck pain: randomized clinical trial for diagnosis and follow-up.
abstract: OBJECTIVE
  A definitive diagnosis of chronic neck pain (CNP) is sometimes not possible. The aim of this study was to understand the possible role of the deep fasciae in CNP and the utility of the ultrasonography in the diagnosis of myofascial neck pain.
  
  
  METHODS
  The morphometric and clinical data of 25 healthy subjects and 28 patients with CNP were compared. For all subjects, the active and passive cervical range of motion (ROM) was analyzed and the neck pain disability questionnaire (NDPQ) was administered. The fascial thickness of the sternal ending of the sternocleidomastoid and medial scalene muscles was also analyzed by ultrasonography.
  
  
  RESULTS
  There were significant differences between healthy subjects and patients with CNP in the thickness of the upper side of the sternocleidomastoid fascia and the lower and upper sides of the right scalene fascia both at the end of treatment as during follow-up. A significant decrease in pain and thickness of the fasciae were found. Analysis of the thickness of the sub-layers showed a significant decrease in loose connective tissue, both at the end of treatment and during follow-up.
  
  
  CONCLUSIONS
  The data support the hypothesis that the loose connective tissue inside the fasciae may plays a significant role in the pathogenesis of CNP. In particular, the value of 0.15 cm of the SCM fascia was considered as a cut-off value which allows the clinician to make a diagnosis of myofascial disease in a subject with CNP. The variation of thickness of the fascia correlated with the increase in quantity of the loose connective tissue but not with dense connective tissue.
