Abstract:   (257 Views)
Background: Ultrasonography (US) can be used to measure the dimensions and the cross-section of muscles. This study aimed to investigate the intra- and inter-rater reliability of the US measures of the cross-section of the longus colli muscle at rest and in contraction states in patients with chronic nonspecific neck pain (CNSNP) and healthy subjects.
Methods: This cross-sectional study was carried out on seven healthy subjects and seven patients with chronic non-specific pains. The cross-section of the longus colli (LC) muscle was measured at rest and in contraction states at the C5-6 vertebrae by two raters using US on two consecutive days. The data were analyzed by the Pearson Correlation Coefficient (ICC).
Findings: The intra-rater reliability was excellent in the healthy (ICC > 0.97) and patient (ICC > 0.095) groups at rest and in contraction. The inter-rater reliability was excellent in the healthy group (ICC > 0.97) in both states and at rest (ICC = 0.98) and in the contraction (ICC > 0.95) in the patient group.
Conclusion: The findings revealed that US demonstrated higher agreement in measuring the cross-section of the LC in healthy subjects and patients with CNSNP. Thus, this method is reliable and can be used to measure the cross-section of the muscles.
