Anthropometry, muscular strength and dermatoglyphics of individuals with Down’s Syndrome

Abstract

Introduction:The study aimed at comparing both the dermatoglyphic and anthropometric features of the strength of palmar prehension people with of Down´s Syndrome, users of the FUNAD in the city of João Pessoa -Paraíba -Brazil. Materials and Methods: Thirty individuals with age between 10 and 30 years-old were assessed (male, n = 18; female, n = 12). Thus, the body mass, the height, the body mass index, the strength of palmar prehension and the palmar fi ngerprint complex were identifi ed. The Shapiro-Wilk test verifi ed the distribution of normality, whereas the non parametric data were verifi ed with the Mann-Whitney test and the parametric data with the Student's "t" test. The signifi cance level (p < 0.05) was used. Results: It was verifi ed that among the three investigated variables there were no signifi cant differences neither in the anthropometry nor in the dermatoglyphics, being the strength statistically different with absolute strength (p=0.00) and relative total strength (p=0.01). There was prevalence of the ulnar loop type in 55% of men and 42% of women, with the Simian line being identifi ed in both hands. Discussion: It was thus concluded that the bearers of Down Syndrome reveal specifi c features in the anthropometrics, muscular strength and dermatoglyphics when observed in terms of sexes.Introducción: El estudio ha tenido como objetivo comparar las características antropométricas, de la fuerza de la presión palmar y dermatoglíficas de los portadores de Síndrome de Down, usuarios de la "Fundação Centro Integrado de Apoio ao Portador de Deficiência" -FUNAD -João Pessoa -PB -Brasil. Materiales y Métodos: Fueron evaluados 30 individuos con edad entre 10 a 30 años (masculino, n = 18; femenino, n = 12). De esa manera se ha identificado la masa corpórea, la estatura, el índice de masa corpórea, la fuerza de prensión palmar y el complejo digito palmar. Se ha utilizado la prueba de Shapiro-Wilk para verificar la distribución de los resultados en cuanto a la normalidad, la prueba U de Mann-Whitney para comparar los datos no paramétricos y la prueba t de Student para los paramétricos, siendo éstos analizados con el nivel de acepción (p<0,05). Resultados: Entre estas variables investigadas, se ha verificado que no hubo diferencias significativas en la antropometría y en la dermatoglifia, siendo la fuerza estadísticamente diferente con fuerza absoluta (p=0,00) y fuerza relativa total (p=0,01). Hubo predominio del diseño presilla del tipo ulnar, con relación a la línea Simiesca su presencia ha sido de 55% en los hombres y 42% en las mujeres, en las dos manos. Discusión: Se concluyó que los portadores de Síndrome de Down presentan características específicas en la antropometría, fuerza muscular y dermatoglifia cuando observados los sexos.

Palmar Dermatoglyphics, a Possible Screening Tool among Some Egyptian Children with Acute Lymphoblastic Leukemia

“…This was the explanation of relating characteristic dermatoglyphics with certain medical genetically based diseases e.g. Kleinfelter's syndrome (Cowger, 1993), cerebral palsy (Proloscic et al (2009), Down syndrome (trisomy 21) (Barbosa et al, 2009), diabetes mellitus (Nezhad and Shah, 2010) and bronchial asthma (Maceo, 2011).…”

“…1-The triradii (a, d, b, and t) were identified. (figure 1a and 1b) (Barbosa et al, 2009). The triradial point is the meeting point of three ridges that form angles of approximately 120 degrees with another (Schauman B and Alter M 1976).…”

“…The specific dermatoglyphic traits were claimed to be inherited as dominant, incompletely dominant, recessive, single gene or polygenic with complete or incomplete penetrance and as a variable expression of genes. Dermatoglyphics has been studied in certain clinical disorders which are associated with chromosomal and developmental defects like mongolism, Turner's syndrome, cardiovascular disease, diabetes mellitus, schizophrenia and ischaemic heart disease (Barbosa et al, 2009, Oladipo et al, 2007, and Wang et al, 2008.…”

Somatic Growth of Brazilian Children and Adolescents With Down Syndrome

“…The literature indicates that this disorder leads to changes in development, with the following characteristics: congenital heart disease, hearing and vision problems, atlantoaxial instability, thyroid disorders, obesity, muscular hypotonia, etc. 2,3 . Disturbances in visual and motor functions are also frequent among this population 2 .…”
