Objetivo: avaliar a correlação entre contratilidade esofágica e força muscular esquelética em voluntários saudáveis. Métodos: Foi realizado estudo de teste diagnóstico com 20 voluntários saudáveis do sexo masculino entre 20 e 40 anos. Foram avaliados dados demográficos e antropométricos (idade, massa, altura e calculado o índice de massa corpórea). A força muscular esquelética da mão dominante foi mensurada por meio do teste de preensão palmar com um dinamômetro digital, sendo aferida por três vezes e então utilizada a média das medidas aferida em quilogramas (kg). Os voluntários foram submetidos à manometria esofágica de alta resolução, sendo mensurado a integral de contração distal (ICD) e integral de contração proximal (ICP). Variáveis paramétricas foram expressas em média ± desvio padrão (variação) e realizada correlação entre elas foi calculada através do teste de Pearson, considerando como significante p<0,05. Resultados: A idade média dos voluntários foi de 30,85 ± 2,41 (30-36) anos, massa média de 74,90 ± 5,09 (63,52 – 87,13) kg e altura média de 1,77 ± 0,05 (1,70 – 1,87) m. A média das 3 mensurações da força de preensão foi de 39,77 ± 5,27 (28,87 – 49,33) kg. A média das 10 deglutições da DCI foi de 1394,96 ± 753,76 (302,06 – 3209,11) mmHg.s.cm, enquanto das 10 deglutições da PCI foi de 362,01 ± 354,75 (58,8 – 707,10) mmHg.s.cm. Não foi observada correlação linear entre as variáveis força de preensão palmar e DCI (R = 0,0969, p = 0,684) e entre as variáveis força de preensão palmar e PCI (R = 0,0455, p = 0,213). Conclusões: Não houve correlação entre força muscular esquelética e contratilidade esofágica em indivíduos saudáveis.
Objective: To assess the correlation between skeletal muscle strength and esophageal contractility in healthy volunteers. Methods: A diagnostic test study was conducted with 20 healthy male volunteers aged between 20 and 40 years. Demographic and anthropometric data (age, weight, height, and calculated body mass index) were evaluated. Skeletal muscle strength of the dominant hand was measured using a digital dynamometer, with three measurements taken and the mean of these measurements recorded in kilograms (kg). Individuals underwent high-resolution esophageal manometry, and the distal contraction integral (DCI) and proximal contraction integral (PCI) were measured. Parametric variables were expressed as mean ± standard deviation (range), and correlation between them was calculated using Pearson's test, with significance set at p<0.05. Results: The mean age of the patients was 30.85 ± 2.41 (30-36) years, with a mean weight of 74.90 ± 5.09 (63.52 – 87.13) kg and a mean height of 1.77 ± 0.05 (1.70 – 1.87) m. The mean of the three grip strength measurements was 39.77 ± 5.27 (28.87 – 49.33) kg. The mean of the DCI for ten swallows was 1394.96 ± 753.76 (302.06 – 3209.11) mmHg.s.cm, while the mean of the PCI of ten swallows was 362.01 ± 354.75 (58.8 – 707.10) mmHg.s.cm. No correlation was observed between grip strength and DCI (R = 0.0969, p = 0.684) or between grip strength and PCI (R = 0.0455, p = 0.213). Conclusions: There was no correlation between skeletal muscle strength and esophageal contractility in healthy individuals.
