Repeatability and intra-rater reproducibility of a digitalized test of body image perception

Abstract

-A body schema is a cortical representation of the spatial relations of body parts. It can be evaluated using the Image Marking Procedure (IMP). However, that instrument lacks information regarding its reliability and a standardized set of procedures. The aim of this study was to test the repeatability and intra-rater reproducibility of an adapted IMP. Methods: It consisted of two steps: (1) adaptation of the instrument; (2) verification of its reliability. Sixty-five young adult women were evaluated on two different days by a single rater, with a one-week interval between evaluations. Three consecutive measurements were performed on each day. Regarding repeatability, for all the variables (coordinates, distances and area), the ICC scores were classified as excellent, with low SEM (<4.5cm) and MDC (<8.5cm) values. Regarding intra-rater reproducibility, only the variables area and distance between the trochanters presented ICC> 0.6. The adapted IMP needs to be conducted only once. Regarding reproducibility, the variables apt for use are the area within the points and the distance between the trochanters. In contrast to the original IMP test, in this adapted version we do not recommend the use of the distances between the shoulders, the hip/waist or the top of the head in relation to the ground.Key words: Evaluation of research programs and tools; Perception; Reproducibility of results. 2) Resumo -O esquema corporal é uma representação cortical das relações espaciais das partes do corpo que pode ser avaliado pelo Image Marking Procedure (IMP), o qual carece de informações acerca da confiabilidade, bem como dos procedimentos de padronização do teste.

Repeatability and reproducibility of a topographic system to evaluate the spine

“…Chaise et al (Chaise et al, 2011) acknowledged the importance of using repeatability as one of the parameters for evaluating the efficiency of a system considering its practicality and accuracy. Schmit et al (Schmit et al, 2017) agreed with this statement, suggesting that excellent repeatability is indicative of efficiency of a system even if only one evaluation is performed.…”

“…Para avaliar a consciência corporal, foi aplicado o teste de projeção de pontos, o IMP (Image Marking Procedure), é um teste frequentemente usado para avaliar a dimensão percebida do corpo, isto é, o esquema do corpo, através da localização percebida dos segmentos (SCHMIT et al, 2017).…”
