Effect of Tetrapolar Interferential Current on Primary Dysmenorrhea Associated with Low Back Pain: Randomized Clinical Trial
Bibliographic record
Abstract
AbstractDysmenorrhea is described as pain or weight in the hypogastrium and can radiate to the lumbar region or to the thighs. The use of the vector interferential current (CIV) is based on two sinusoidal currents of medium frequency, modulated at low frequency, and can reach deep tissues in a pleasant way. Despite widespread use of this current under various conditions, there are few studies on its use in primary dysmenorrhea associated with low back pain. The aim of this study was to evaluate the analgesic effect of the Tetrapolar Interferential Current on primary dysmenorrhea associated with low back pain. The study consisted of 20 volunteers, divided into 2 groups: Placebo Group (GP) and Group Treatment (GT), with treatment for 3 days in two menstrual cycles. The variables analyzed were the McGill Pain Questionnaire at the beginning of the first intervention and on the last day after the procedure, and the Visual Analog Pain Scale, applied before and after each therapy. It was observed that for the McGill questionnaire there was reduction only for the treated group, for the Pain scale there were differences again between groups and between evaluations, and the size of the effect showed favorable results in the treated group. The interferential current in the quadrilateral form was shown to be effective in reducing pain in young patients with primary dysmenorrhea.Keywords: Visual Analog Scale.

O uso da corrente interferencial vetorial (CIV) baseia-se em duas correntes sinusoidais de média frequência, moduladas em baixa frequência, podendo atingir tecidos profundos de forma agradável. Apesar de amplo uso desta corrente em várias condições, há poucos estudos sobre seu uso na dismenorreia primária associada à dor lombar. O objetivo do estudo foi avaliar o efeito analgésico da Corrente Interferencial tetrapolar na dismenorreia primária associada à dor lombar. Este estudo foi composto por 20 voluntárias, divididas em 2 grupos: Grupo Placebo (GP) e Grupo Tratamento (GT), com tratamento por 3 dias em dois ciclos menstruais. As variáveis analisadas foram o Questionário de Dor de McGill no início da primeira intervenção e no último dia após o procedimento, e a Escala Analógica Visual de Dor, aplicada antes e após cada terapia. Observou-se que para a o questionário de McGill houve reduç o apenas para o grupo tratado, para a escala de Dor houve diferenças novamente entre grupos e entre avaliações, sendo que o tamanho do efeito mostrou resultados favoráveis ao grupo tratado. A corrente interferencial na forma tetrapolar mostrou-se efetiva na redução do quadro de dor em jovens com dismenorreia primária.Palavras-chave: Escala Visual Analógica.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
