RESUMO

Currently, there is no research consensus regarding the influence of body position on verticality perception in acute stroke. In this study, we aimed to compare the influence of half-lying and sitting positions on measurements of the subjective visual vertical (SVV) and the subjective haptic vertical (SHV) of individuals in the acute stroke phase. In this cross-sectional study, we compared these positional experiences in two groups of participants: adults in the acute stroke phase and elderly individuals without stroke. Independent variables were stroke versus no-stroke groups, in half-lying versus sitting positions. Analyzed variables of related interest were cognition (Mini-Mental State Examination or MMSE), stroke severity (National Institutes of Health Stroke Scale or NIHSS), and trunk control (Trunk Impairment Scale or TIS). Dependent variables were visual and haptic verticality, as evaluated by SVV and SHV. There were observed differences in absolute SVV in sitting position between groups (p = 0.021), absolute SVV in half-lying position between groups (p = 0.033), absolute SHV in sitting position between groups (p = 0.003), absolute SHV in half-lying position between groups (p = 0.002), and constant SVV in half-lying position between groups (p = 0.007). In the stroke group there was a higher coefficient of variation of SVV and SHV in the half-lying position compared to sitting position. In the sitting position, we observed a very strong correlation between the TIS and absolute SHV (p = 0.008). We concluded that individuals in the acute phase of stroke had greater misperceptions of visual and haptic verticality than older adults without strokes and that individuals in the acute phase of stroke showed less variability in visual and haptic vertical perception in the sitting position than in the half-lying position. By implication, we should encourage the sitting position in the acute stroke phase and develop early strategies to increase the verticality perception.

RESUMO

Introducción: En China la prevalencia del sobrepeso y obesidad está aumentando de manera vertiginosa. Objetivo: Valorar la autopercepción corporal de los adultos chinos y determinar su relación con los indicadores antropométricos. Métodos: Se realizó un estudio observacional de corte transversal en Panzhihua, China. La muestra estuvo conformada por n = 151 sujetos, con edades comprendidas entre los 18 y 80 años que cumplieron con los criterios de inclusión establecidos. Se les realizó cuestionario a través de una entrevista presencial y mediciones del peso, talla, circunferencia de la cintura y de la cadera, determinaciones del índice de masa corporal, índice de circunferencia de la cintura y la de cadera y el porcentaje de grasa corporal. Resultados: Según la clasificación del porcentaje de grasa corporal se determinó normopeso (10,6 por ciento), 28,5 por ciento con sobrepeso y 60,9 por ciento con obesidad. De acuerdo con el índice de masa corporal se encontró en el nivel delgado (5,3 por ciento), 47,0 por ciento normopeso, 32,5 por ciento en sobrepeso y 15,2 por ciento obesos. Según el índice de circunferencia de la cintura y la de cadera, 34,4 por ciento fue normal y 65,6 por ciento presentó obesidad abdominal. La autopercepción corporal: 54,7 por ciento de los sujetos se autopercibieron como normopeso, 24,3 por ciento tenían una percepción de sobrepeso y 12,2 por ciento se autopercibió obeso. Las correlaciones entre la autopercepción corporal, el índice de masa corporal y el porcentaje de grasa corporal expresaron diferencia significativa (p ;0,05), la autopercepción corporal y el índice de circunferencia de la cintura y la de cadera no evidenció diferencia (p> 0,05). Según la correlación de Pearson, el porcentaje de grasa corporal fue más confiable como indicador. Conclusión: La autopercepción corporal de los sujetos en esta investigación no fue adecuada. El porcentaje de grasa corporal fue el indicador antropométrico más confiable del estudio(AU)

Introduction: In China, the prevalence of overweight and obesity is increasing dramatically. Objective: To assess the body self-perception of Chinese adults and to determine their relationship with anthropometric indicators. Methods: An observational cross-sectional study was conducted in Panzhihua, China. The sample was made up of n = 151 subjects, aged between 18 and 80 years who met the established inclusion criteria. A questionnaire was conducted through a face-to-face interview and measurements of weight, height, waist and hip circumference, determinations of the body mass index, waist circumference index and that of the hip and the percentage of body fat. Results: According to the classification of the body fat percentage, it was determined 10.6 percent normal weight, 28.5 percent overweight and 60.9 percent obesity. According to the body mass index, it was found 5.3 percent in the thin level, 47.0 percent normal weight, 32.5 percent overweight and 15.2 percent obese. According to the waist and hip circumference index, 34.4 percent was normal and 65.6 percent had abdominal obesity. Regarding body self-perception, 54.7 percent of the subjects self-perceived as normal weight, 24.3 percent considered themselves to be overweight and 12.2 percent self-perceived as obese. The correlations between body self-perception, body mass index and body fat percentage expressed a significant difference (p;0.05), body self-perception and the waist and hip circumference index showed no difference (p;0.05). According to the Pearson correlation, the percentage of body fat was more reliable as an indicator. Conclusion: The body self-perception of the subjects in this research was not adequate. Body fat percentage was the most reliable anthropometric indicator in the study(AU)

RESUMO

This study reports on the development, reliability, and validity of a new instrument for obtaining respondents' body image perception, the Brazilian Photographic Figure Rating Scale (BPFRS). This instrument consists of eight photographic images (seven distorted and one accurate) of respondents themselves in standardized poses, taken just prior to requesting respondents to make self-ratings on the instrument. Participants involved in developing and evaluating this instrument were 142 Brazilian women (age 21.8 ± 3.0 years). Ten experts assessed content validity and showed high agreement (defined by ratings of 4-5 on a 5-point scale) with items measuring underlying constructs and high (>70%) interrater agreement. A Pearson correlation demonstrated convergence between the BPFRS and other related scales; a positive correlation was also evident between actual and respondent-perceived body mass index. Both test-retest and Kappa confirmed temporal stability. These findings indicate that the BPFRS can accurately and reliably assess body image dissatisfaction and body perception in young women by deploying realistic, personalized images as stimuli for self-ratings. Implications for further research and treatment of body image problems are discussed.
