It was a longitudinal study of the effects of musculature co-contraction training on the muscles of the vertebral axis of the head and neck in the following two weeks of the experiment.
Study design: Quasi experiment design.
Methods and Subjects: Quantitative researches were used to compare horizontal distances of forward head from the plumb line of the head and neck at the interval of one-week post-experiment and two week post-experiment (four intervals), measured with an improved line level and a smart ruler. Altogether there were 55 subjects (aged 19 to 27) from colleges, 28 females (50.9%), 27 males (49.1%). Among them 39 subjects were aged 19-21 (70.9%).
Results: After the analysis of descriptive statistics, the experiment found with the help of a modified exercise bar, the FHP distances of the subjects significantly decreased. After assessing the distances of forward head at four intervals it was found that the effect started to diminish a week after the experiment and continued to diminish in the second week. After the first week showed the subjects, 19 mild sufferers (34.5％), 29 moderate sufferers (52.7％), 7 severe suffers (12.7％). conducting the paired t-test to analyze the difference of five–pair. it was found the five–pair comparison results also showed different degrees of corrections of forward head postures. The analysis of the four intervals shows there were no statistically significant differences between males and females. Before the experiment, the head forward of those aged 22-24 (6.8 cm) is severer than those aged 19-21 (5.6cm) One–way analysis of variance (one–way ANOVA) analyzed the severity of forward head within the pairs and among the pairs at the four intervals and found only at the intervals of pre–experiment and two–week post–experiment were there obvious differences among the different age groups. After one–way ANOVA and Scheffe’s multiple comparisons, it was found after the experiment, the 25-27 age group improved more than the 22-24 age group. While the average distance of the former decreased from 7.9 cm to 4.4 cm, that of the latter decreased from 6.8 cm to 4.8 cm. After the experiment those aged 25-27 had a distance correction of 3.5 cm better than the other two age groups, but the tracing study of comparison at the one–week post–experiment and two–week post–experiment intervals showed those aged 22-24 had an average retrogression of 0.6 cm, but better than that of the 0.7 cm of the 19-21 group and that of the 3.4 cm of the 25-27 age group. All of them showed as time passed by, the improvement of distances of forward head were diminishing.
Conclusion: The analysis of the statistics of different intervals showed 45 of the 55 subjects had restorations of forward head posture while 6 showed no difference and 4 retrogressed. The successive analysis showed that at the one–week pre–experiment interval, 41 of the subjects had restorations of forward head posture while 6 showed no difference and 8 retrogressed. Further analysis showed at the two–week post–experiment interval, 35 of the subjects kept restorations of forward head posture while 3 showed no difference and 17 retrogressed. Though with diminishing effects, corrections could be observed.
