Caracterização da síndrome cruzada superior (SCS): relações com dor e hábitos posturais

Abstract

Introducion: The development of portable technological devices due to the need for instant communication, associated with the typically sedentary profile of the current population, leads to the development of postural and musculoskeletal adaptations, among them the Upper Crossed Syndrome (UCS). Objectives: Identify the frequency of the postural pattern associated with the characteristic imbalance of UCS and the existence of a relationship with postural habits, sedentary lifestyle and painful symptoms in university students. Methods: Questionnaires on postural habits and the presence of musculoskeletal pain were performed, muscle strength analysis through scapular and lumbar dynamometry tests, and the maximal repetition test (MRI) of the pectoral muscles, neck flexors and upper trapezius, as well as postural evaluation with the observation of photographic records in the frontal, right lateral and left lateral planes in 50 university female students. Results: Of the volunteers evaluated, 52% presented a typical UCS postural pattern. There was a high index of lumbar, scapular weakness of the pectoral and flexor muscles of the neck. There was a high frequency of painful symptoms mainly in the lower back, neck and shoulders. It was noted that 40% practice physical activity, 77.8% use laptop computers weekly and 100% use smartphones daily. Conclusions: It was not expected in this study to find UCS in all volunteers; however, the postural habits evidenced and the presence of pain are two factors that, although they have been shown to be independent, denounce trends not restricted to UCS but that deserve attention, such as high percentage of low back pain and weakness found in this vertebral segment.
