Eletromyografická analyza cervikální flexe v závislosti na pozicích těla / Electromyographic analysis of the cervical flexion during different body positions

Author: Hirofumi Sageshima Title: Electromyographic analysis of the cervical flexion during different body positions Aim and Purpose: The aim of this study is to find out the muscle activity and the muscle coordination during cervical flexion in 3 different positions - standing, sitting and supine - with electromyographic analysis in young healthy adults. Methods: This study compared superficial cervical flexor muscles activity during conventional cervical flexion to 20 volunteered healthy subjects with surface electromyography (EMG). The activity of 5 paired muscles - sternocleidomastoid, scalenus, suprahyoid, infrahyoid and superior part of trapezius - were measured when they performed 15-time cyclic cervical flexion-extension from neutral to maximum cervical flexion on 3 different positions - sitting, standing and supine - in random order. Results: Significantly higher EMG amplitude was detected from all measured muscles on supine position than sitting and standing (p < 0.05). It was also confirmed that muscle activation pattern was different according to positions; its amplitude on supine reach the peak in the earlier phase of movement, while it was delayed on 2 other positions (p < 0.05). In terms of onset, all cervical flexors activated together in the very beginning. However, on sitting and...
