Reliability of Cobb’s Angle in a Measurement of Kyphosis – A Meta–Analysis

Abstract

This study aimed at analyzing the literature systematically on the reliability of Cobb’s angle in measurement of kyphosis. Cobb’s angle is the most widely used measurement to quantify spinal deformity. Kyphosis is the spinal disorder in which an excessive outwards of the spine results in an abnormal rounding of the upper back. Cobb’s angle used as standard measurement to determine and trackthe progression of scoliosis andkyphosis. Hence the purpose of the meta-analysis is to analyze the reliability of Cobb’s angle in a measurement of kyphosis Systematic searches in PubMed, Science direct, Google scholar, Cochrane library, Research Gate for systematic review was done. Research article and review article were selected within the published 1999 – 2020. The study design is Meta-analysis study of Analytical type. Study quality was done by PEDro Scale The study duration is about 4 months. A Meta-analysis was conducted by using Medical software to obtain a summary estimate of the standardized mean difference and 95% confidence limit. 100 articles taken for review in which finally 35 articles were summarized. Almost all the study shows that there was a highly significant difference on measurement of kyphosis using COBB’S angle. Outcome of measurement has excellent reliability with the small range of standard error of measurement. Cobb’s measurement had excellent reliability when used to measure kyphosis. The findings confirm the significance and the ease of using this method.
