Study Of The Causes And Exercise Intervention Of Cross-stitch Neck Shoulder Syndrome

Cross-stitch is craftsmanship which has a long history. This manual skill requires little in simple working environment as well as workers, which in return cross-stitch enjoys a great popularity among the public nowadays. This job demands high focus for a long time, nearly static, of which the traits and category is similar with that of current stitchers, accountants, and computer staff. Long time working, however, caused muscle tension, decreased elastic of muscle, uncomfortable neck-shoulder as well as increased cervicobrachial syndrome. This dissertation aims at studying and analyzing biomechanics which induces mentioned problems. What is more, a further survey will be demonstrated about the cervicobrachial syndromeoccurring among the workers who engage in cross-stitch or similar category jobs. This essay will provide scientific proof and measures for people who got cervicobrachial syndrome out of sedentary working habits.This paper selected six females who know of as well as engage in cross-stitch aging from 20 to 26. They live near enough to facility the quantity experiments. First, we performed myoelectricity test on muscles around neck and shoulders of subjects and collected the surface discharge of neck-shoulder muscles before starting the stitch job. Second step is organizing subjects to stitch for three hours each day in successive ten days and performing myoelectricity test on neck-shoulder muscles again. At last, under the condition of three-hour stitching in ten successive days, subjects were required to do exercise after one-hour work. At the end of the ten-day job with exercises intervention, we performed the last myoelectricity test. The three tests were compared and analyze.The result shows:1,long-time cross-stitch can induce fatigue in neck-shoulder muscles.2, the repetitive cross-stitch work can cause this phenomena occurring ahead of time.3, Appropriate exercise intervention is effective to ease the fatigue which can be deduced by the difference of surface discharge before and after exercises.
