Abstract

Introduction: The way to carry the baby may cause imbalances in muscles related to the spine. Objectives: To investigate the electrical activity of the muscles trapezius descending fibers and lumbar erector during the simulation of carrying a baby. Methods: 20 volunteers right-handed and healthy participate of the study during walking on a treadmill to simulate the act of carrying the baby in different ways: 1) horizontal position; 2) vertical position; 3) Support Type "kangaroo" and 4) Support Type "sling". The EMG results were analyzed by analysis of the intensity of the electromyographic signal of the muscles trapezius fibers descendants and spinal lumbar erector bilaterally. Results: A two-way ANOVA indicated that the way of loading (F(4, 59)=17.1 p <0,001) and next (F(1, 59)=89.6 p <0.001) affected the intensity of the activity spinal erector muscles and also the way of loading (F(4, 59)=6.4 p <0.001) and next (F(1, 59)=59.9 p <0.001) of the trapezius muscle fibers descendants. Conclusions: Kangaroo support generated less activation in spinal muscles during when compared to other situations.
