RESUMO
Introduction: The radio electric asymmetric conveyer (REAC) is a technology that has the purpose of restoring the cellular polarity triggering the rebalancing of the endogenous bioelectric field, which considering the neurological dysfunctions, affects the neural communication mechanisms. The studies published so far show that the REAC neuromodulation technology has positive effects in treating these dysfunctions, with the principles of endogenous bioelectricity as a basis to achieve these effects. Objectives: This study aims to review the literature that explored the effects of REAC protocols on motor control and to identify which mechanisms would be involved. Materials and methods: This integrative review considered studies that used REAC as a therapeutic intervention directed at human motor control and experimental research with animals that applied REAC to obtain effects related to motor behavior. Results: Ten articles were included, eight clinical and two experimental studies. The clinical studies used the neuro postural optimization (NPO) protocol in 473 patients, of which 53 were healthy subjects, 91 were Alzheimer's disease patients, 128 were patients with atypical swallowing, 12 subjects with neurological diseases, and 189 were without the specification of disease. The experimental studies used the antalgic neuromodulation and neurodegeneration protocols in animal models. Conclusion: The information integrated in this review made it possible to consider REAC technology a promising resource for treating motor control dysfunctions. It is possible to infer that the technology promotes functional optimization of neuronal circuits that may be related to more efficient strategies to perform motor tasks.
RESUMO
INTRODUCTION: Abdominal hypopressive gymnastics appeared as an alternative to traditional abdominal exercises to promote abdominal muscles strength without overloading the pelvic floor muscles (PFM). To determine the activation level of abdominal muscles and PFM and the posture influence in the level of activation in these muscles during abdominal hypopressive gymnastics, we used surface electromyography in young and healthy multipara women. METHODS: This is an observational study with eutrophic nulliparous women aged between 18 and 35 years, with abdominal skinfold less than or equal to 3 cm and active or irregularly active physical activity. Surface electromyography was used for rectus abdominis, external oblique, transversus abdominal/internal oblique (TrA/IO) and PFM assessment in the supine, quadruped and orthostatic (upright standing) positions during abdominal hypopressive gymnastics using normalized electromyographic (%EMG) data. We also analyzed the difference in activation between each muscle and between muscles and positions. RESULTS: Thirty women were evaluated and the mean age was 25.77 years (SD 3.29). The group formed by the TrA/IO muscles and the PFM showed higher %EMG in all the positions assessed, followed by the external oblique and rectus abdominis muscles. A comparison of %EMG of each muscle between the different positions showed differences only in rectus abdominis between the supine and quadruped (p = 0.001) and supine and orthostatic positions (p = 0.004), and in TrA/IO between the supine and orthostatic (p = 0.023) and orthostatic and quadruped positions (p = 0.019). CONCLUSIONS: The results suggest that abdominal hypopressive gymnastics can activate the abdominal muscles and PFM and the position do not have influence on electromyographic activation level of the PFM and external oblique.
