Avaliação da dor, mobilidade cervical e eletromiografia do músculo trapézio em pacientes com cervicalgia inespecífica pré e pós mobilização visceral: estudo placebo controlado, randomizado cego

Abstract

Non-specific neck pain (NS-NP) is characterized by multifactorial causes, such as a change in the mobility or functioning of viscera that are found in the abdominal cavity, due to a possible neural relationship between these two regions. Thus, the objective of this study was to evaluate the pain, cervical mobility and electromyographic activity of the upper trapezius (UT) muscle in patients with NS-NP pre and post immediately visceral manipulation (VM) and after 7 days. This study was a placebo-controlled, randomized, blind study of subjects with IC. Thirty individuals with NS-NP were divided into two groups: Manipulation Group: 15 subjects treated with visceral manipulation and Placebo Group: 15 subjects receiving placebo treatment. The possible effects of the therapy were verified by the analysis of the pain performed through the Numeric Pain Rating Scale (NPRS) and by the measurement of the area of pain, the electromyographic activity of the UT muscle and the cervical mobility. In the analysis of mobility and pain verified by the area of pain, NPRS and algometry, no significant difference (p> 0.05) was found between the studied groups. The results obtained in the ANOVA of the group interaction (F = 0.09, p = 0.05, p2 <0.001) and treatment vs group (F = 0.69, p = 0.49, p2 = 0.006), showed no influence of VM on the amplitude of the electromyographic signal of the UT muscle. The present study demonstrated that a single intervention of visceral manipulation, of the stomach and liver, does not alter the pain, cervical mobility and electromyographic signal of trapezius muscle descending fibers, both in immediate posttraining and after 7 days.
