Abstract :
Background: The purpose of this research was to compare the score of functional screening test in dentists with and without the complication of upper cross syndrome. Materials and Methods: A number of 30 dentists (age 39.97±5.47 years and body mass index 23.71±1.82 kg/m2) voluntarily participated in this research, who were selected by available selective sampling method and they were divided into two groups of 15 people (group 1, simultaneously suffering from upper cruciate syndrome anomaly and group 2, without anomaly). Motor performance screening tests including deep squat, hurdle step, launch, rotational stability, push up stability, shoulder range of motion and active leg raising were measured in all participants. Also, the head and shoulder forward a(1)ngel and the kyphosis angel were measured to detect the mentioned abnormalities. Kolmogorov-Smirnov test was used to normalize the data. To compare the demographic variables between two groups, one-way analysis of variance (ANOVA) test, to compare each of the FMS tests between two groups with and without upper cruciate syndrome, the non-parametric U-Man-Whitney test, and if the distribution of the results is normal, from Parametric independent t test was used. Also, independent parametric t-test was used to compare the overall scores of FMS tests. The collected data were analyzed with SPSS version 16 software at a significance level of 0.05. Results: Test scores of deep squat (P=0.003), launch (P=0.001), shoulder range of motion (P=0.000) and rotational stability (P=0.001) between two groups with and without deformities There was a significant difference in forward head and shoulder and kyphosis. However, there was no significant difference between the two groups in the test of stepping over the obstacle (P=0.397), active leg raising (P=0.133) and push up endurance (P=0.143). Discusion: From the results and discussions of this research, it can be concluded that the spine acts as a chain. So that the change in the curvature in any part of it can also change its muscle structure; This means that the muscles in that area can be weak or shortened. These changes in one of part of the spine can cause changes in the muscle structure of other areas.In the present research, according to the score of the seven FMS tests, it was found that the change in the muscle structure of the head, neck and chest causes a change in the muscle structure of other trunk areas and the scores of the tests are reduced.
