Effects of Baduanjin and PNF on Upper Crossed Syndrome Among University Students in Henan Province，China

In this study, the comparative design is referred to as a descriptive approach because of its appropriateness. This study was conducted primarily through an experimental intervention. It was a randomized controlled trial of 12 weeks duration. In this process, the research instruments and markers were prepared and then during the experiment, the comparative study was a descriptive comparative method, which was mainly described by comparing the changes in data before and after the experiment. This study includes three main aspects of the variable study. The first aspect was the range of motion of the neck joints, which consisted of six main variables: head extension, posterior extension, left extension, right extension, left rotation, and right rotation. The second aspect is the static postural index of patients with upper crossed syndrome. The FHA and FSA variables were selected for assessment in this study. The third aspect is the rating of patients' self-perceptions before and after the experiment, including the degree of cervical pain, the degree of cervical disability and the degree of anxiety. Also, these three aspects were the main measurements of the pre-test and post-test.

The specific process of this study was to first recruit subjects through WeChat and then screen them according to the UCS criteria set in this study. After screening, 90 university students with UCS were selected for random grouping. This experiment by different intervention methods can be divided into two experimental groups, Baduanjin group and PNF group, and a control group, that is, no intervention group. After the grouping, a pretest was administered to evaluate mainly from neck range of motion, static posture and self-perception. After the pre-test, each group received the experimental intervention treatment for 12 weeks. 12 weeks later a post-test was administered, which was consistent with the pre-test. The final data collected.
